EDITOR’S COMMENT

A NEED FOR A NUCLEAR EXPLOSION – PEOPLE THAT IS!

T

he governments current target for building a further 5 nuclear plants has moved from 2025 to 2030 – okay it’s a considerable and costly programme and no doubt along the way there will be hiccups, but one thing that it ensures is a considerable number of jobs for the building industry which is of course great. However, in the meantime there is an enormous mountain to climb; that of finding the expert staff to manager them. Sadly today there is a decline in the graduate uptake across the whole of the process industries and the traditional manufacturing industries; chemicals, pharmaceuticals, food & beverages etc are suffering as more attractive options open for them, areas such as the automotive and aerospace industries for example and this is compounded as older & experienced engineers become fewer. With the industry continually developing and introducing new technologies and with a lower graduate base to follow on, will robots become even more dominant? There will be great opportunities in the ‘new nuclear age’ but where will the ‘new’ batch of qualified engineers come from to man these new establishments? Let the campaign to find them start now!

SPECIALIST CDM FOR THE PROCESS & CONSTRUCTION INDUSTRIES A new company specialising in the supply of Construction (Design and Management) services for the process engineering and construction sectors is reporting a huge demand for their services following the changes to the CDM regulations that came into force on April 6. HFL:CDM Ltd was established in July 2015 as a direct response to customer demand for CDM consultancy for process engineering projects but has already been selected to provide these for Bio Products Laboratory (BPL) Ltd, the Elstree-based producer of human plasma products in a three year alliance, and several other clients in the chemical, petro-chemical and pharmaceutical sectors. HFL:CDM Ltd’s Managing Director, Wayne Baxter, commented, “Our sister company, Haden Freeman Ltd, had provided Health & Safety advice to the process industries from its formation in 1984, including CDM specific support since the regulations were introduced in 2007. This included the provision of CDM Coordinator, a role in which we worked for a large number of our process industry clients, in addition to our expertise in HAZOP, HAZID and Functional Safety projects.” “Following the changes to the regulations in 2015, however, and the resultant increasing demand for CDM advice and services within the construction and process industries, HFL-CDM was set up not only for general construction clients but also for those undertaking new build or expansion schemes to their production and processing plants. – a niche field requiring construction, engineering and H&S expertise and experience. This includes the provision of the all-important Principal Designer role.” “Process Engineering projects differ from normal construction in several critical ways, foremost of which is the specialist knowledge of various engineering disciplines required to understand the total project – civil, structural, mechanical, chemical, electrical, control systems, instrumentation and safety engineering are involved in most process industry projects whereas normal construction projects require a less broad range.” “However, where we might differ from other providers of such services, is that we are not just professional H&S providers but rather bring real, practical experience of large complex construction projects which enables us to dramatically reduce risk for our clients via tried and tested lean management principles. There are many firms offering resources which explain the new regulations but we are one of the few that has real multi-discipline expertise and experience to enable us to offer almost a ‘one-stop shop’ to both the process and construction industries.” For further details, please contact Wayne Baxter by E-mail: wbaxter@hadenfreeman.com.

APPLICATIONS NOV SUPPLIES MORE MONO™ PUMPS TO MAJOR ANAEROBIC DIGESTION OPERATOR NOV has provided two of its Mono™ progressing cavity pumps which are now helping manage some 12,000 tonnes of material each year, including 7,500 tonnes of food waste, at a major recycling plant in Weston-super-Mare. An EZstrip™ transfer pump and a Compact C range pump were installed as part of an Anaerobic Digestion (AD) process operated by the award-winning waste management company, Cory Environmental. Three other EZstrip pumps are also in use at the plant. “We are one of the UK’s leading waste management companies, and our customers rely on us to provide them with reliable and efficient waste management and recycling services,” says Alistair Holl, Director of Cory Environmental Resource Management. “Our existing Mono equipment from NOV had performed well, and that was a major factor in our decision to use two additional Mono pumps to handle the depackaged organics which go into our AD process. This is mainly food waste which can be quite aggressive on the rotors and stators of any pumps involved, so it was also important that we chose equipment that we knew would deliver in this sort of demanding application.” NOV’s focus on developing pumping solutions which are designed to meet the specific requirements of specialist industries such as AD made the company an ideal pump provider for Cory Environmental.

NOT SHAKEN, NOT STIRRED… BUT MIXED Maximising the benefits of renewable energy continues to be the focus for an increasingly diverse range of companies who are continuing to invest in the anaerobic digestion (AD) process and a new bio-energy plant at the Glendullan distillery is a good example. Diageo Scotland Ltd, have a number of distilleries in the ‘Whisky Trail’ area located in Speyside, Perthshire and have invested around £1bn in increasing production capability and enhancing their bioenergy facilities. Mixing is an essential part of the AD process and SYSTEM MIX LTD who market the Rotamix Dual Zone Mixing System, have made an important contribution in supplying mixing equipment to both the Dailuaine and Glendullan distilleries. The mixing system installed at the Dailuaine Bioplant consists of a single Vaughan HE10R12-381 horizontal end suction chopper pump driven by a 37 kW rated motor and 4 internally floor mounted double nozzle assemblies to mix a 24.5m diameter digester tank. The success of this initial AD project was an important factor in the decision to upgrade the Bioplant at the Glendullan distillery, where another single pump mixing system is operating successfully. As the sole UK suppliers of the bespoke design ROTAMIX (Digester Mixing) and STM (Small Tank Mixing) tank mixing systems using the integral VAUGHAN chopper pump, System Mix are making an important contribution to the success of AD plants in the ‘food’ waste sector. For example, problems such as solids settlement are commonplace reducing active digester volume and can result in a significant reduction in output, leading to failure of compliance requirements. Also compressors in ‘traditional’ gas mixing systems and submersible in-tank propeller systems are often associated with labour intensive maintenance issues, resulting in process downtime and associated costs.

APPLICATIONS NEW VEGA LEVEL SENSOR REACHES PARTS OTHERS CAN’T! Another success for high frequency contactless radar level sensor E&JW Glendinning is the largest independent supplier of quarry and concrete products both to the trade and direct to the end user in Devon and Cornwall. Over recent years, they have embarked upon an expansive programme of modernisation and automation, creating a state-of-the-art aggregates processing and supply facilities, which is essential to their business goals and to compete in the modern aggregates market. As part of this they need high-tech sensor solutions to deliver the automation and control philosophy they are seeking. They make high demands on equipment to get the best performance out of their plant. The secondary crusher at the heart of the screening and grading plant in the quarry is typical of this requirement. The feed hopper above it is a critical process control point, this is where the majority of aggregate comes through at some stage. It is a noisy, dusty environment, with unpredictable flow patterns and material behaviours. The crusher itself is capable of processing up to 400 tonnes an hour and the whole plant 4000 tonnes a day. With this level of throughput, its vitally important to get accurate information and control to optimise productivity, energy consumption and product quality from the crusher. Originally, as is the case with most sites in the sector, non contact ultrasonic level sensors were installed. However, the noise, dust and product build up regularly delivered unreliable performance for the control they required. This single measurement problem resulted in regular production halts, poor process and energy management and resets of the sensors to clear the problem. The ultrasonic units required regular maintenance: from cleaning transducers, adjusting angles and tweaking software to try and make them perform as they wanted. Their engineers needed to improve the plant performance to a level that satisfied both their customers and themselves. To achieve this they turned to VEGA to trial one of their new VEGAPULS 69 radar level sensors in this tricky, critical control point. The application consists of a feeder hopper over 8m high and around 5m square at the bottom two sides slope down onto a central crusher feed. The hopper can be fed from any one of three different conveyors, which can be simultaneous, and the stone size feeding in can be from dust up to 250 mm, as the majority comes from the primary crushing plant. Inside the feed silo it gets a heavy build up of stone on the ‘shoulders’ of the coned section, forming a narrower ‘rat hole’ to the bottom. This material rarely moves, so it was important for the sensor to be able to reliably read down past this point. The VEGAPULS 69 was installed in the existing mounting position of the ultrasonic sensor, very close to the main infeed into the bunker. It was commissioned by the plug-in programmer on the top of the device. As soon as it was installed on the empty silo, with no extra adjustments, the sensor was able to read right down to the bottom of the bin to the outlet conveyor, which boded well. Then, with just a few minor adjustments to optimise the performance of the sensor and its output, the radar has worked successfully without incident for over 3 months, providing a smooth level output to enable operators to effectively control crusher throughput and the conveyor speeds. This without need for extra maintenance work and a reduction in downtime caused by measurement problems, a first for this area of the process. So why is this radar so different? VEGAPULS 69 works with very highly focused 79GHz microwaves, not sound waves, to provide a very small beam angle (3.5°), along with optimised sensor performance for solids handling. This, combined with radar’s natural immunity to inflight dust, filling noise and air turbulence, means it promises to be one of the most capable and versatile solids level sensors ever. It is now proving itself in difficult unmeasurable applications. The site engineer said “We like VEGA sensors, as we install them, fit them and they get on with their job. We don’t have to keep going back with minor tweaks”. He added, “We also like the continuity of the programming system, all that is needed to set a sensor up is the PLICSCOM display/programmer that simply slots onto the housing that enables access all of the information and gets a sensor up and running quickly and easily and only need one programmer for all devices.” E&JW Glendinning are now confident enough of the radar devices’ performance, that they have embarked upon a schedule of installing them across the plant, replacing ultrasonic sensors.

MONO™ PUMP from NOV SET TO REPEAT 30-YEAR SUCCESS

COLCHESTER ZOO PUMP OVERHAUL

A Mono™ Compact C progressing cavity pump from NOV has replaced a previous Mono pump that had operated without any problems for over 30 years. The new pump is being used in fertilizer production by GrowHow – a leading UK fertilizer manufacturer, and a major supplier to the chemical process industry. The original SH80 pump had given good effluent transfer service for over three decades. “It was still working well, but GrowHow decided to upgrade to a new pump,” explains NOV’s Paul Green. “We proposed a Compact C range pump as the modern alternative.” “We needed something which combined excellent suction lift performance with the ability to handle high suspended solids content,” continues GrowHow’s Chris Smith. “It also had to withstand the very aggressive nature of the effluent, so that it could provide a high level of reliability. The new pump has fitted the bill perfectly and is providing even better performance than the old SH80 unit.” The new pump is driven by a fixed-speed gearbox, operates at 245rpm, handles a 3.25 bar pressure and provides a 19 m3/h capacity. It draws the effluent from an interceptor pit on a 3m lift, and transfers it over 100m to a holding sump.

Gibbons Engineering Group conducted an overhaul of the two main 55kW water pumps serving the Colchester Zoo sea lion enclosure. This was because vibration readings were exceeding ISO recommended levels, while the mechanical seals required replacement. Gibbons’ comprehensive package of work included the lift and shift of the pumps which were returned to our premises for The sea lion enclosure at overhaul and re-instated on completion. The project also included the replacement Colchester Zoo of the bearings plus removal and reinstatement of the coupling assembly. For precision alignment, the coupling was set up using our state-of-the-art laser aligner. The refurbished pumps and motors were set to work and checked for running current and vibration levels before returning to normal service.

INDUSTRIAL PERISTALTIC PUMPS REDUCE THE COST OF OWNERSHIP FOR PAPER AND PACKAGING MANUFACTURER Challenge A leading paper and packaging manufacturer in Australia was using Air-Operated Double Diaphragm (AODD) pumps to deliver 4-colour ink to its printers. The on-site AODD pumps were using considerable amounts of compressed air and required constant maintenance due to the wearable parts (seals and valves). This was resulting in unacceptable long downtimes and high cost: for repair and purchase of new parts. The customer requested for pumps that could offer increased durability and low maintenance, reducing the cost of ownership by lowering repair/service costs. In addition and more importantly, the pumps needed to deliver shear sensitive inks to the printers without foaming or separation. Solution After assessing the process, Australian Verderflex distributor, Global Pumps were able to recommend the Verderflex Rapide R8 Peristaltic Industrial Tube Pumps to replace existing AODD pumps. The Rapide R8 belongs to the Verderflex® Rapide family of simple to operate industrial tube pumps which are perfect for heavy duty applications, where viscous mediums are being pumped. The R8 has a maximum flow rate of 470 l/hrand discharge pressures of up to 2 bar. These industrial peristaltic tube pumps have a compact footprint, deliver high output, offer multi-directional orientation of the pump head and are available with dual pump head as an option. These key features make the Rapide easy to integrate into your working process. The customer saved both cost and time by having high dependability and only one wearing part – the tube. With a simple clamping mechanism enabling tube change, the pumps are easy to maintain onsite, without requiring specialist repairs. There are no seals or valves to replace, nor impellers that can become clogged. Result A very happy customer quoted that the Verderflex Rapide R8 is a “great pump and very reliable”. In addition to the benefits described above, the customer was delighted that the pumps also save money on ink during setup/cleaning between jobs by being reversible. They simply pump any unused ink back into the supply after the print job is finished. For more information contact Verderflex Ltd, Castleford, West Yorkshire.

STEEL MAKER IMPROVES ROLLER TABLE RELIABILITY WITH AC DRIVES A steel maker is improving the reliability of its roller table by retrofitting four ABB variable-speed drives. The roller table has 80 rollers to transport finished steel billets at Celsa Manufacturing’s plant in Cardiff. Each drive controls four banks of 20 roller motors. Celsa’s existing roller table drives were obsolete and it was getting difficult to source spares for them.As a trial, ABB authorised value provider, APDS, installed an ABB general purpose drive, ACS550. Although the objective was not energy saving, APDS estimate that Celsa will be saving about 30 percent on its energy costs for this drive. All the motors are connected to the drive using scalar control. Some drives do not like the inductance imbalance that goes with trying to control so many motors, but with the ABB drive, it’s simply sized for 20 motors and there is no need for a filter.

APPLICATIONS

“EASY DECISION” TO UPGRADE TO SPIRAX SARCO’S HEAT EXCHANGER SYSTEMS CONSIDERABLE SAVINGS FOR FLOWPLANT CUTS LEIGHTON HOSPITAL’S WATER THANKS TO INVEND™ HEATING COSTS BY 10-15% The UK’s leading distributor of industrial maintenance, repair and overhaul (MRO) products and services, Brammer, has helped Flowplant save 60 per cent on its consumable spend through industrial vending solution, Invend™. Flowplant manufactures and supplies equipment for a range of industrial applications, such as drain and sewer cleaning, abrasive blasting and descaling and hydrostatic testing. It is essential for them to have sufficient stock of consumables to ensure downtime is minimised. One of the problems was with small value, high volume items, as they are difficult to track and control in terms of stock holding. Storage was another problem area for Flowplant, with items either locked up in cupboards which slowed down access, or handed out items to all employees, leading to a high volume of cash tied up in consumable stock. Additionally, Flowplant’s historic management of low-value consumables consisted of paper ordering and the purchasing department having to constantly liaise with stores, which were not always open when stock was required. Brammer’s Invend™ allowed Flowplant to benefit from an industrial vending machine service without the upfront cost of having to purchase the machine. Brammer installed the Invend™ machine into Flowplant’s factory, giving site managers a complete oversight of what is being used, by who and how often. It can be used on a 24/7 basis. Mark Bastable, Managing Director of Flowplant, said: “We have been delighted with the introduction of Invend™ in our manufacturing facility. We have received fantastic feedback from our operators, who find the ease of use a considerable benefit, as well as the availability of equipment to them during all times of the day.” For further information, visit www.brammer.co.uk/invend

ROTORK CMAS ENABLE SHALE GAS WELL COMPLIANCE WITH EPA EMISSIONS MANDATES

Leighton Hospital has cut its water heating costs by an estimated 10-15% per annum by upgrading its hot water system to two Spirax Sarco EasiHeat™ steam-to-hot-water systems. The installation by Leighton Hospital, a 540bed acute hospital in Crewe, brings the total number of EasiHeats at the site to ten, underlining the hospital’s confidence in the technology’s superior reliability and energy efficiency. The EasiHeat systems will supply almost 90% of the DHW in the main hospital building. “Our aims in installing the latest EasiHeat systems were to achieve a more accurate control of our outgoing water temperature, eliminate wasted energy due to storing large volumes of hot water, and reduce/eliminate scheduled maintenance works regarding annual inspections,” explains Brian Colley, Energy & Environmental Engineer at Leighton Hospital. “We have a lot of experience with plate heat exchange systems, which meant our decision to upgrade to the EasiHeat systems was an easy one to make – we knew they would be perfect for this project.” Spirax Sarco EasiHeat is a ready-to-install system that uses steam in a compact, plate heat exchanger to deliver water on demand at a constant, stable temperature. As the hot water is supplied on-demand, there is no need to store it, avoiding the associated energy losses and significantly reducing the risk of Legionella. “Before we installed the EasiHeat systems, we had to pasteurise the water by keeping it at 80°C for an hour before we could open it up onto the circuit. Then, because it is domestic hot water, we had to cool it down before it could be used, which was a huge waste of energy. Installing the EasiHeat systems means it is no longer necessary to store hot water, which will reduce carbon emissions.” The EasiHeat systems are also expected to reduce maintenance costs at Leighton Hospital. Unlike calorifiers which are pressure vessels and must be stripped down for annual insurance inspections, EasiHeats do not need to meet this requirement, saving substantial maintenance costs.

Rotork CMA electric control valve actuators have delivered an efficient and reliable process control solution and eliminated venting and greenhouse gas emissions in compliance with new environmental protection legislation at remotely sited shale gas installations in the USA. Traditionally, spring diaphragm actuators powered by the produced gas have been used, but recent EPA (US Government Environmental Protection Agency) mandates now limit this process to lower fugitive emissions caused by bleed gas. A shale gas company in Louisiana was therefore looking for an affordable and efficient low power solution that could be run by solar panels to replace existing actuation equipment and control a variety of fluids at line pressures up to 413 bar (6000 psig). Most shale wells and flow lines are unmanned and located in remote areas that are difficult and expensive to monitor. Skilled technicians must check data and perform manual shutdowns, increasing costs for the time to travel to site, identifying the problem and stopping the flow, which is not cost-effective or practical. Actuators provide an ideal solution to automate valves at the remote wells. The key objective was to provide an efficient and reliable process control actuator which could be retrofitted on installed valves to reduce costs and downtime. Rotork’s local agent Setpoint Integrated Solutions engineered an interface to enable CML-250 actuators to be easily fitted to installed valves and improve the level of control, without venting gas and with the low power demand required for solar powered operation. Designed for quarter-turn, multi-turn and linear valve operation, robust Rotork CMA actuators perform numerous process control valve, choke valve, metering pump and damper applications demanding precise position control and continuous modulation. Single-phase or DC electrical power is all that is required for simplified installation and control valve actuation. Explosion proof certification to international standards is available for hazardous area applications. Recent developments enable the CMA to be specified with increased functionality encompassing local controls, LCD positional display and programmable fail-to-position performance. The success of this solution has enabled the Louisiana customer to standardise on the CMA actuator for future flow control applications. Around the world, increasing numbers of CMA actuators are used for similar duties.

ENERGY SAVINGS IN THE CAN FOR BRAMMER AND BALL Expertise in pump management and maintenance from Brammer, the UK’s leading distributor of industrial maintenance, repair and overhaul (MRO) products and services, has delivered £30,000 in energy savings for Ball Packaging Europe, a leading manufacturer of beverage cans. Ball regularly reviews opportunities for reducing energy consumption as part of a commitment to reduce the carbon footprint of its beverage cans by 25 per cent by 2020. Identifying its high pressure can cleaners as an area for improvement, they called in Brammer to conduct an extensive audit. Each of the two production lines at Ball’s Rugby site is supplied with hot water by five immersible pumps. Brammer found that the 10 pumps within the can cleaners were at least 20 years old, providing an opportunity to upgrade to more modern, energy-efficient models. With a run time of 8,400 hours per annum, based on the pumps running 24/7 for 50 weeks of the year, Brammer identified potential energy savings of more than 450,000 KWHh/yr. With a clear opportunity to provide more efficient, cost effective pumps which would reduce consumption and optimise flow, Brammer worked with strategic partner Grundfos pumps to recommend replacements – Grundfos MTRE64 and MTRE45 series pumps – and carry out initial energy monitoring. The new pumps were installed as part of a fully integrated pump, motor and variable speed drive package, and were selected on the basis of the warranty and support available within Brammer’s turnkey solution. Thanks to a significant reduction in energy usage, the associated cost savings have provided Ball Packaging with a return on investment in only 12 months, with projected savings set to rise beyond £400,000 in the next ten years. John Cosgrove, Plant Systems Manager at Ball Packaging Europe, commented: “We were impressed with the thorough up-front audit from Brammer, as well as the comparison testing and custom fabrication the team were able to provide. The installation was quick and caused negligible disruption to our production processes. We are now looking at how we can replicate these results at our other sites.” For further information on Brammer’s MRO products and value-added services, visit www.brammeruk.com

MAKING THE MOST OF YOUR

IT INFRASTRUCTURE Tony Mannion, Business Unit Leader Industrial IT from SolutionsPT, looks at the pressures faced by manufacturing businesses and the tell-tale signs that they’ve outgrown their infrastructures.

M

aking the jump from SME to a larger enterprise is exciting, but not without its challenges. Having the right software and technology in place is essential to growing a business, yet many companies – particularly manufacturers – are being constrained by out-dated process and applications. So how can decision makers identify when their IT systems have reached the tipping point? Following the recent financial downturn and subsequent on-going recovery, it is now essential for manufacturers to ensure they maximise their assets and applications to achieve their business goals. As IT has become an increasingly vital service to manufacturers, so too has the requirement for systems not to fail and for performance to remain consistent. In order to stay ahead of the curve, UK manufacturers must utilise the latest innovations in technology. This becomes increasingly important when you consider a recent Government Department for Science report, which highlighted the UK manufacturing industry as one of the sectors that will undergo drastic change in the coming years, as the impact of the Internet of Things becomes more widespread. The Internet of Things is just one of a host of new approaches that will allow manufacturers across the country to gather smarter, ‘realtime’ analytics meaning they can see how and why their factories are performing. However, before manufacturers are in a position to adopt and adapt, they must take a close look at the quality of the IT systems they are currently running. There are many pressure points that manufacturers need to be aware of when it comes to the performance and strength of their IT systems. Ageing assets and legacy replacement are among the costliest hurdles, often requiring replacement to avoid unexpected and unnecessary downtime. Increased competition requires systems which give manufacturers the edge and ability to operate faster and increase productivity. With cyber threats increasing across the globe, security and resilience is now, more than ever, a key aspect of IT systems.

BEWARE – LITTLE THINGS MEAN A LOT…

Identifying these potential issues before they turn into more serious problems is vitally important and there are a number of tell-tale signs that can help manufacturers spot the first signs of an outgrown IT system. For instance, if the cost of maintenance and continued usage of the system become prohibitive, it is time to look at a replacement structure. Similarly, as businesses grow, so too does the amount of data that is generated. If systems are not set up to support this growth then manufacturers could be basing key decision making on false, incomplete or inaccurate data. Accurate data is essential to achieve operational intelligence and drive efficiency. The inability of systems to adapt is a further indication that it is time to reassess IT provisions. This can be identified by businesses spending vast amounts of time and money integrating data from different sources and equally large resources used on system maintenance. The most damaging result of inflexibility can be as the company is growing and expanding into new markets or launching new ranges, the infrastructure and system it is based on is limiting and therefore holding it back. Today’s

PROCESS INDUSTRY INFORMER September 2015

manufacturers need to offer their customers flexibility. Whilst some may want a standard product, others will require variations bespoke to certain markets. Older systems often prevent manufacturers responding flexibly to these requests, leading to lost revenue opportunities. As a company grows, so does its geographical spread. Opening international offices or production sites will only add to the pressure placed on existing systems. These offices, or sites, need to be able to communicate seamlessly. They will all be producing their own data, but to ensure the overall business is operating efficiently, engineers and operatives need access to all the information being produced. If the correct system is in place then data silos are created where potentially valuable data that could drive business decisions is simply wasted. Often the most costly indicator that a manufacturer has outgrown its IT systems is when it becomes over reliant on manual processes – processes that, in an ideal scenario, the system could take on itself. IT is supposed to drive efficiency by making automation processes easy to implement and increase output standardisation. However, if the system is not performing, existing workloads will be added to through the necessity to manually check systems and correct any issues. This said, few companies are able to afford a complete overhaul of their IT systems and infrastructure, so the key to delivering much needed improvement is by managing the existing legacy systems. This can be achieved by carefully protecting and preserving IT investments to ensure that they remain operational and perform to a high standard for as long as possible.

DON’T PANIC, HELP CAN BE AT HAND…

Legacy systems can also be migrated onto new manageable, scalable technology. Legacy IT system migration is the process of transferring data or programs from one computer system, software application or website to another. This may involve physical system migration, when old hardware is no longer capable of meeting the needs of the system or if it has been damaged. It may also take the form of software or databased migration, where files, data, users and many other settings are transferred between systems. Ensuring that the right knowledge and experience exists within organisations can guarantee that IT systems are maximised to work efficiently, delivering the support and services required. However, this does not have to mean employing an entire new workforce of IT specialists. In truth, the skills gap within the IT sector means that more companies are turning to managed services to support their IT systems. This means that a third party can be used to manage and monitor IT systems, allowing manufacturers to benefit from their expertise and knowledge, whilst providing the peace-of-mind that systems are operating as expected and risk and downtime are reduced. Ensuring that factories are secure from cyber threats, operating efficiently and producing to a high quality should be high on any manufacturers list of priorities. What links these separate issues is that they can all be improved by ensuring that IT systems are fit for purpose. Importantly, it is now time for manufacturers to review their plant floor infrastructure and what options are available to them. It comes down to a simple choice – preserve and protect or modernise.

STAYING CYBER SAFE IN INDUSTRY By Jonathan Wilkins of Stafford based European Automation In 2014, the total number of cyber security incidents detected rose to 42.8 million according to PWC’s Global State of Information Security Survey 2015, which you can find at http://goo.gl/ MZR3zg. For those of you that have not done the maths, that is 117,339 attacks per day, every day. And these are just the strikes that were detected and reported.

T

o comprehend the sheer extent of current threats, antivirus business Kaspersky has created an interactive map. It depicts the number and type of cyber threats in real time. If you are reading this white paper online, I am sure you will agree that it is almost hypnotic. If you are reading offline, I recommend you visit http:/cybermap.kaspersky.com. But the map is also incredibly worrying. The total number of security attacks detected increased by 48 per cent from 2013 to 2014 and there is little evidence to suggest this percentage will decrease in 2015. Despite these figures, it appears that information security programs have actually weakened, due largely to naivety and inadequate investment. In the industrial sector alone, companies reported a 17 per cent increase in detected security incidents in 2014. The resulting financial costs increased by 34%, while research from Barclays suggests that nearly 50% of businesses that suffer a cyber security attack cease trading. This special report analyses the increasing global cyber threat and outlines the value of implementing a business focussed security strategy to ensure the wellbeing of both employees and industrial automated systems.

WHO DONE IT?

The year 2014 featured some of the biggest hacking and cyber security breaches of the decade. It seems nobody was safe, not even the biggest corporate players. eBay, Sony Pictures Entertainment, Apple and Sony Playstation, were all victims of cyber attacks in one form or another. Interestingly, there is one thing most security threats have in common and that is the source. The results of PWC’s survey illustrate that 34.55 per cent of companies asked, reported that the attacks on them last year were estimated to originate from current employees of the company and 30.42 per cent from former employees. These were the two biggest culprits. Statistically, you are far more likely to come under cyber attack because of someone plugging in a corrupted USB stick to your network, than you are to be specifically targeted by a hacker trying to exploit a weakness in an automated system. However, that’s not to say that you shouldn’t prepare for both eventualities. Hackers still ranked highly in the survey - third with 23.89 per cent of companies surveyed pinning their security attacks on them. However, there is another, less prevalent threat that companies should be aware of too. Every business encounters third parties on a daily basis - such as consultants, contractors, suppliers and providers. It is imperative that the information shared

18

with these parties, on and off site, is restricted to an appropriate level. 18.16 per cent of businesses surveyed responded that they believed their current third party providers were responsible, actively or passively, for their cyber attacks. For example, the US retail giant Target had a considerable breach in 2013 when the personal identifiable information (PII) and credit card details of customers were stolen. The multi-staged hack began with Target’s heating, ventilating and air conditioning supplier, who, it would seem, had access to Target’s network. Credentials were stolen from the US vendor using common malware implemented through an e-mail phishing campaign. This was the hackers’ way in. The moral of the story is that to develop secure systems, companies must implement technical, conceptual and organisational measures to prevent different types of security threats.

WHERE TO START

In a manufacturing context, typical security incidents include infection by malware, unauthorised use, manipulation of data, espionage and denial of service - the latter being an attempt to make a machine or network resource unavailable for its intended users. Defence against these kinds of threats takes more than simply investing in new software or hiring a Chief Information Security Officer (CISO), although these measures are a good start. Changes need to be implemented from the ground up. Before we get ahead of ourselves there are certain steps that should be taken prior to anything else. To evaluate properly the likely threats, system owners must first assess the weak points of that system - including the human element. In an automated environment, this may reveal a scenario in which a property of the whole is considered beneficial from an automation perspective, but detrimental from security one. For example, a remote device that is free to gain access to a programmable logic controller (PLC) without authentication saves time in an automated process. However, from a security perspective this is a definite weak point. It is necessary to identify these weaknesses in order to access risks and take appropriate action. Manufacturers and industrial companies should pay particular attention to three core areas. The first is the weak points that arise due to improper equipment or software implementation. This could be a faulty device or piece of programming. The rise of interconnectivity and the Internet of Things allows everything in a

PROCESS INDUSTRY INFORMER September 2015


factory to communicate using a common protocol, generating a large amount of data. This brings us to the second area companies should focus on: securing the mass data flow so that hackers cannot exploit it. Finally, weak points often arise due to organisational measures, or lack thereof. For example, it is important to ensure that the CISO’s team update operating systems, web browsers and applications whenever necessary. This negates the worry of using a product that has known flaws, which a developer has corrected in a later version. You should implement a corporate policy dedicated to updating software to solve this problem. Overall, it is essential that, during an initial security assessment, the team identify, group and isolate the critical information belonging to the business so that the CISO’s team can properly protect it. This should be the main priority for any company concerned with its cyber security.

NETWORK PROTECTION

One of the most effective means of safeguarding automated production systems is cell protection. This form of defence is especially effective against a number of different threats, including man-in-the-middle attacks, whereby the attacker has the ability to monitor, alter and inject messages in a communications system. Cell protection employs a security integrated component that supervises access to an automated cell. This is often referred to as a doorman, because it plays the same role as its human namesake by deciding who can and who can’t come in. The most common device used for this purpose is an industrial Ethernet communications processor that integrates a firewall and virtual private network (VPN), filtering out attacks and keeping the network connection secure. Cell protection also prevents unauthorised access and control, denial of service attacks and online threats via the office network. However, it is important that risk assessments and security measures don’t focus solely on automated systems. Staff, suppliers and third party providers should also come under scrutiny.

SECURITY VIA EDUCATION

Part of the current problem is that the topic of cyber security isn’t being elevated to a board level discussion in most companies despite the damaging consequences of security breaches including loss of production, reduced product quality and safety threats to both humans and machines. Most governments have created or are in the process of creating, cyber security regulations that impose conditions on the safeguarding and use of PII. Companies that fail to sufficiently protect sensitive information risk financial penalties. Despite this, some companies remain ignorant. Regulations are particularly prevalent across Europe and should serve as an example of what countries that do not yet have legislation should expect in the near future. The US also has mandatory conformance policies when it comes to companies protecting PII. At the beginning of 2104, the US implemented a framework for improving cyber security infrastructure: a set of industry standards and best practices aimed at helping organisations manage cyber security risks. However, these measures have been heavily criticised for not going far enough, especially in light of the recent high profile Sony Pictures Entertainment hacking scandal allegedly involving North Korea. To help educate businesses in the ways of information security, the UK Government has allocated £860 million until 2016 to establish a National Cyber Security Programme. Part of this agenda is to ensure the UK is one of the most secure places to do business online. This comes after it was revealed that 81 per cent of large corporations and 60 per cent of small businesses in the UK reported a cyber breach in 2014.

Under the programme, the Government has developed a cyber essentials scheme to give companies a clear goal to aim for. This will allow businesses to protect themselves against the most common cyber security threats but also advertise that they meet this standard. For more information about the scheme, go to www.gov.uk/government/publications/cyber-essentials-scheme-overview. In addition, a ‘Ten steps to cyber security booklet’ is available for anyone seeking advice on current risks and methods of prevention. The literature outlines important elements when creating a business-focussed security strategy, such as risk management regimes, secure configuration, network security, user privileges, education and awareness, incident management, malware prevention, monitoring and home or mobile access. The security booklet can be downloaded by going to www.gov.uk/government/publications/cyber-riskmanagement-a-board-level-responsibility. Businesses that want to find out more about how to increase their security levels can also access a useful guideline document from the industry standards agency PROFIUBUS & PROFINET International (PI). The Security Guideline for PROFINET was originally developed in 2006 and later revised at the end of 2013. It specifies ideas and concepts regarding how and which security measures should be implemented. It also contains a list of commonly used security acronyms and offers a series of proven best practices, such as the cell protection concept mentioned earlier. PROFINET’s guide can be downloaded by going to http://goo.gl/yT7rKW. The information is out there for companies seeking advice regarding cyber security. However, from the statistics provided by PWC’s survey, it would appear that industrial product companies are already leading the way.

INDUSTRY

On the whole, cyber threats are increasing and yet information security budgets seemed to decrease in 2014. The industrial products market is the exception because it has created budgets to protect itself. According to the PWC security survey, this sector, more than all other surveyed - power and utilities, healthcare, retail and consumer, technology and financial services - appears to understand rising security risks. Moreover, it’s investing accordingly. Information security budgets for industrial products companies have soared more than 150 per cent in the past two years. In 2014, information security spending represented 6.9 per cent of PWC survey respondents’ total IT budget, the highest of any sector surveyed. However, in 2014, security incidents in the sector also increased six fold. So perhaps even a 150% increase is not enough. The result of this investment has been notable improvements in security processes and technologies, as well as training initiatives. However, there is still generous room for improvement.

STAY SAFE

Megatrends such as Industry 4.0, the Internet of Things and big data have driven industrial automation to a completely new level, creating more efficient and sophisticated production lines. Industry is integrating its manufacturing lines with IT layers and the traditional industrial automation pyramid is collapsing due to the need for faster, cheaper and more effective production. However, there is a price for these gains: with greater openness, interconnectivity and dependency comes greater vulnerability. There is a definite need for more training when it comes to cyber security, both at the top and bottom of the manufacturing ladder. Too often businesses slip into common pitfalls - believing they are either untouchable or not a target. If the majority of cyber attacks in 2014 were committed by current employees of the affected company, how many of these do you think were undertaken knowingly? Or were they the result of an individual not fully understanding that his or her actions could lead to security breaches? Understanding that you don’t have to be a desirable target for hackers and that cyber threats can be the result of non-malicious, poor judgement from one employee is key to understanding the risks. Even if management wholeheartedly implements a dedicated cyber security downwards, all it takes is one malware-infected device plugged into the network to cause disruption. We cannot prevent accidents, but it is possible to manage them by instilling knowledge in employees and putting in place reliable monitoring devices and procedures for when an attack occurs. Security training shouldn’t be limited to a one off seminar for the staff and an initial systems upgrade. Patch maintenance and updates need to be carried out as and when vulnerabilities are revealed or new software is released. Senior management need to implement vigorous maintenance and monitoring policies. Security is a constant and evolving concern, not something that can be solved with one quick fix. Risk assessments need to be undertaken for suppliers, providers and contractors and restrictions on information should be put in place. Again, this can’t simply be an initial appraisal. Unified procedures should be written up and followed when dealing with any third party that requires a certain level of information from a business. With financial investment and appropriate attention paid to cyber security infrastructure and procedures, a business will be ready should a malicious external attack take place. Otherwise, a company does not just face loss of production and financial penalties; there is also loss of reputation and potential danger to both machines and humans to consider.

THE ENERGY SAVINGS OPPORTUNITY SCHEME (ESOS) & PUMP SYSTEM AUDITS The Energy Savings Opportunity Scheme (ESOS) Regulations 2014 came into force on 17 July 2014 and are a mandatory energy assessment and energy saving identification scheme for large undertakings (and their corporate groups). The scheme applies throughout the UK. ESOS Energy Audits have the potential to increase businesses profitability and competitiveness by identifying cost-effective savings which, if implemented, will improve energy efficiency. The scheme is estimated to lead to £1.6bn net benefits to the UK, with the majority of these being directly felt by businesses as a result of energy savings. ESOS is the UK Government’s approach to transposition of Article 8(4) of the EU Energy Efficiency Directive, which requires all large (non-SME) enterprises to undertake energy audits by 5 December 2015 and every 4 years thereafter. The scheme’s regulations are published on the government’s legislation website http://www.legislation.gov.uk/uksi/2014/1643/contents/made More information about the Energy Savings Opportunity Scheme can be found on the ESOS webpage https://www.gov.uk/energy-savings-opportunity-schemeesos Guidance has also been published to help potential participants in the scheme understand their obligations and on page 43 of the full ESOS guidance document you will see that the ISO/14414-Pump System Energy Assessment standard is referenced as an auditing methodology that can be accepted by “Lead Assessors” approved by the Environment Agency. Accordingly it is hoped BPMA CPSA accredited persons (who are trained according to the IS0 14414 standard) will be recommended by Lead Assessors to undertake the pumping system elements of company energy audits. And bear in mind: • Pumps are the largest consumers of global motive power • Pumping System improvements can deliver up to 40% reduction in energy costs - and therefore improve user bottom line P&L account performance • The fact that BPMA’s CPSA scheme has been designed to help by equipping people with the skills to conduct a Pumping System Audit in accordance with ISO/14414 So when considering auditing your pumping systems, remember the BPMA Certified Pump System Auditor Scheme (http://www.bpma-cpsa.co.uk) has established BPMA as THE body to train and certify personnel who undertake “Pumping System Assessments” as referenced in UK Government Energy Strategy documents BPMA are now offering the opportunity to attend a four day residential course culminating in certification and eventual personal ID “Certified Pump System Auditor” status following approved audits.

WEG LAUNCHES COMPACT HYDROELECTRIC GENERATORS WITH SHORTER LEAD TIMES WEG, a global leading manufacturer of drive technology, has launched two new series of efficient, high quality and compact hydroelectric generators - GH11 and SH11 - with up to 70% more power density than previous models. As a result, engineers can benefit from a low weight and space-saving solution for easier installation. The new generators are also available with shorter lead times thus helping hydroelectric power stations to reduce downtimes and increase productivity. With rated capacity from 500 to 18,000 kVA., the GH11 and SH11 8-pole to 36-pole hydroelectric generators are available with frame sizes from IEC 630 to IEC 1800 and output voltages from 400 V to 13.8 kV at 50 or 60 Hz. The hydroelectric generators provide excellent reliable performance. The GH11 series is designed for standard applications with relatively small and simple turbines, while the robust SH11 series is designed to meet more demanding specifications for turbines and complex hydroelectric power stations. The SH11 generators have a modified mechanical and electrical design that allows them to be operated with higher inertial forces and relatively large axial and radial loads despite their compact construction. They can also withstand adverse conditions such as high continuous speeds or load shedding. WEG’s generators are easy to install and commission in existing plants because the design is based on a standard technology platform. WEG has standardised the production of the new WEG3793 The GH11 series of hydroelectric generators offer generators and key components are provided in the preliminary design stage. As a result, cost-effective and smart solutions for common hydroelectric the manufacturing process is therefore similar to series production and end users can benefit applications without forcing users to sacrifice efficiency or quality from shorter delivery times. The generators are highly versatile and can be easily adapted to individual application specifications. “WEG is committed to helping its customers increase efficiencies throughout its process, and this includes reducing downtime. By delivering products to customers as fast as possible means they can get their process up and running quickly, therefore maximising productivity and profitability,” says Marek Lukaszczyk, European & Middle East Marketing Manager at WEG. Both the GH11 and SH11 can be installed either horizontally or vertically and are available in versions for brushless excitation (with or without an auxiliary exciter) or static excitation with brushes.

Pioneering for You 4


REDUCE COSTS WITH A SUNDYNE HMD KONTRO SEALLESS SUMP PUMP Sundyne HMD Kontro has extended its range of vertical inline sealless pumps with the development of a sump pump variant. The new GSPVS, which meets the requirements of API 685 (as applicable to this style of pump) and is fully ATEX compliant, has been designed for use in tank farms for tank fuel transfer, as well as in oil and gas refineries, chemical and petrochemical processing plants. The vertically mounted GSPVS pump provides all of the benefits of a magnetic drive pump in a compact package, using fewer parts with no seal systems for reduced cost operation. Composed of modules which can be joined to reach a total assembly length up to five metres / sixteen feet, the GSPVS is mounted on a base available to ANSI B16.5 or to customer specific requirements, including lifting points as standard. The modular construction uses a flexible jaw coupling to join drive shafts and to absorb misalignment, decreasing vibration and increasing life expectancy. Greased for life ball bearings are used along the column, removing the need for lubricating or cooling the intermediate sleeve bearings using system fluid. The use of labyrinth bearing seals and a suction strainer avoids external contamination to maximise seal and lubrication life. Sundyne HMD Kontro has more than twenty-five years’ experience in API applications and over a sixty-five year heritage in magnetic drive technology. It was the first pump manufacturer to develop a sealless pump. With stricter demands for the safety and welfare of both personnel and the environment being imposed, sealless pumps are playing an increasingly important role. Sundyne HMD Kontro is continuously developing and extending its range, as improved magnet drive technology enables ever more efficient and powerful pumps to be built, widening the application scope of this versatile pump format.

ACT NOW TO BEAT EU CHANGES TO WASTEWATER TREATMENT REGULATIONS - In the wake of changes to EU wastewater treatment legislation, the right preparation and early investment in accurate chemical metering makes commercial sense - Both municipal and industrial wastewater processors must take heed - Better chemical metering is an important step in that process

by Andrew Ashton, UK Sales Manager, Watson-Marlow Fluid Technology Group Over the past few months, signals have been emanating from Brussels that hint at tighter wastewater treatment regulations. For instance, not only has Carlos Moedas, EU Commissioner for Research, Science and Innovation, recently been calling for better treatment systems for wastewater, but former Environment Minister, Janez Potocnik, has backed a Friends of the Earth report lobbying for improvements on water reporting and pollution.

PUNITIVE MEASURES

Time is of the essence regarding this increasingly urgent matter, as a number of recent actions indicate. Since March of this year, the EU Commission has taken France to court over non-compliance with legislation on urban wastewater treatment, and asked Poland to bring its national laws on groundwater protection into line with the Groundwater Directive. Put simply, recent EU documents on water policy contain key recommendations that encourage action on industrial plants and pollution. History shows that such recommendations and encouragements are often precursors to law.

UNDERCURRENT OF CHANGE

Clearly, there is an undercurrent of change with regard to wastewater and its associated treatment, for both municipal and industrial processes. As with all change, the trick is to make improvements ahead of the game, which means that water companies, the treatment chain and industrial water users, need to start thinking about correct and thorough preparation, as well as investment in the right technology. Better treatment of wastewater, through improved chemical metering technologies, is among the primary ways to help. Better chemical metering is important for many reasons. For example, to help reduce operational expenditure, higher concentrations of chemicals are being used by plants to help reduce transportation, handling and storage costs. This increases the demands on metering pumps for higher accuracy, higher viscosities and greater chemical compatibility. As a result, the inherent precision and performance attributes of the latest peristaltic chemical metering pumps are proving increasingly popular.

COMPATIBLE TECHNOLOGY

Beyond precision, an increase in chemical concentration requires the pump fluid contact materials to have stronger chemical resistance. Although this can prove problematic to many pump types, in peristaltic metering pumps, nothing but the tube touches the fluid, eliminating the risk of the pump contaminating the fluid, or the fluid contaminating the pump. This also makes this pump type ideal for high concentration or aggressive chemicals. The absence of ancillaries, such as back-pressure valves, pulsation dampeners, degassing valves, foot valves, strainers and float switches, all of which are typically required to support a diaphragm pump installation, is another major benefit. As a result, peristaltic metering pumps, which instead feature a single piece pumphead, offer simpler configuration, reduced spares inventory and lower total cost of ownership (TCO).

MAINTAINING EXCELLENCE

Maintenance remains a key driver in the water treatment market. With the recent recession and economic conditions that remain challenging, many plants have seen budgets squeezed. As a consequence, there has been reduced spend on infrastructure and operations, which has led to poorly maintained facilities without adequately trained staff to repair them. This makes switching to peristaltic metering pumps – which unlike gear pump, piston or diaphragm pumps commonly used for chemical metering, feature no expensive seals, valves, diaphragms or rotors to leak, clog or corrode – a shrewd business move. For example, a 520DuN/REM peristaltic pump from WMFTG has met the immediate needs of three chemical dosing schemes implemented recently at

6

various Severn Trent Water facilities. Deployed as part of a temporary dosing rig constructed by engineering group, Costain, the three schemes to date have seen the peristaltic pump used for ferrous chloride and ferric sulphate dosing. The feedback has been very positive: “In my mind there are so many things that can go wrong with a metering pump,” says Paul Pearson, Process Commissioning Engineer at Costain. Only the tubing requires replacement, which is quick and inexpensive, and provided this is done at the recommended intervals, there won’t be any problems. We’ve certainly had no issues so far.”,” he concludes. Peristaltic metering pumps score well against other pumps types in a number of performance areas. For instance, while a typical diaphragm metering pump a flow range of 100:1, this is expanded to 875,000:1 with a peristaltic pump.

TRANSPORTATION AND ACCURACY

The accuracy of a peristaltic pump is 0.5% in comparison with the 5% accuracy of a typical solenoid pump. Chemicals are not cheap, hence accuracy can be enormously beneficial in terms of saving costs’. For example the Togliatti, Russia plant of steel wheel manufacturer, Mefro Wheels, has opted to use our latest Qdos 30 metering pumps at the facility’s water treatment unit. As well as featuring patented ReNu pumphead technology, which is fully contained for safe, tool-free maintenance, the pump’s metering accuracy clearly caught the eye of Mefro engineers. “When compared with some manufacturers of metering pumps, including diaphragm types, we were surprised by the high accuracy characteristics declared in the brochure,” says a Mefro spokesman. “However, following operational measurements, these characteristics were substantiated completely.” Consider this; to reduce the cost of transporting chemicals, more and more companies are using higher concentrations. For example, calcium hydroxide in suspension is normally offered at 18%; but to be competitive on transportation, this is being increased to 45% in the UK. Higher concentrations require greater accuracy to ensure that chemicals are not over- or under-metered.

MORE ADDED VALUE

Boosting the added value offer, peristaltic pumps do not require pumped fluid to be continually present, which means the pumps can run dry without costly downtime or repairs. Furthermore, the recovery of the tube as part of its operating principle creates a powerful self-priming action that allows the pumps to move liquids containing entrapped air. Peristaltic metering pumps also offer reversible action, so if a blockage should occur it can be cleared at the flick of a switch.


the use of modern pumphead technology on peristaltic models ensures safe containment.

FLOCCULATION

Many plants use diaphragm pumps to perform flocculation, The use of common clarifying agents such as ferric chloride can lead to clogging - an unwanted effect that increases both maintenance and process downtime. Moreover, environmental conditions such as temperature, affect fluid viscosity and consequently diaphragm pump performance. In fact, most diaphragm pumps struggle to pump viscosities of 2500 cP or more. Typically, flow must be reduced to 25% and the system designed sufficiently to achieve accurate performance. Conversely, the latest peristaltic pumps deliver accurate metering even with fluctuating viscosity, while their powerful suction capability eliminates the need for a day tank or specialist piping schemes.

HIGHER FLOW OR HIGHER VISCOSITY?

For applications where extremely high flows or product viscosity are present, robust hose pumps can provide the solution. Market leading hose pumps deploy heavy duty bearings within the pump rotor, eliminating overhung load. In addition, high torque gearing aligns directly to the pump housing and is protected by a buffer zone. Among the key features of hose pumps are: suitability for high viscosity and/or high flow applications; suction lift capability to 9 metres; dry running and selfpriming; simple design; no slippage (allowing true positive displacement for accurate and repeatable metering); no ancillary equipment; and full reversing capability to blow out suction and drain lines safely. Convenience food manufacturer, Greencore Group Plc is an excellent example of a business that has achieved significant savings in downtime and repair costs on the water treatment plant Greencore thanks to the installation of a Bredel 50 high pressure hose pump. At this Yorkshire site, our technology is used for dosing a magnesium hydroxide solution [Mg(OH)2] that helps correct fluctuations in pH levels caused by food effluent, resulting from frequent wash-downs. Switching from a ‘budget’ dosing pump to the this model means there are no longer any abrasion issues leading to downtime or repair, thus reducing costs. According to Greencore Group, the pump “paid for itself extremely quickly”

PRE-EMPT CHANGE – AND START SAVING NOW

In general, smarter water management and pumping technologies represent the optimum strategy for treatment facilities moving forward. This is because water is on course to be scarcer than oil by 2030, with demand outstripping water supply by 40%. Close to half the world’s population will be living in water stressed areas. And yet wastewater reuse stands at just 2.4% of all water withdrawals globally. Public attitudes to wastewater reuse will need to change, with greater levels of chemical metering becoming a necessity.

With the tides of change clearly beginning to shift in regard to wastewater regulations, organisations and companies should grasp the chance to improve performance. In the first instance, getting ahead of potentially tighter legislation can provide a certain level of futureproofing. Secondly, it can save money when competitor organisations are later rushing to install the systems required to catch up. In short, there’s no sense in waiting; embedding the best wastewater treatment systems not only begins to save money immediately, it pre-empts changes and places businesses in a better position to win new contracts.

APPLIED SOLUTIONS

Among common water treatment applications is disinfection using chemicals such as sodium hypochlorite, which is known to create gas locking and crystallisation in diaphragm pumps. When metering disinfectant, flow rates and pressure changes can fluctuate, impacting metering accuracy. Diaphragm pumps are often set to ‘over-dose’ to ensure water quality is maintained as they are frequently not accurate below 30% of their peak flow. For sodium hypochlorite this “over-dosing” usually results in excessive levels chlorine which need to be subsequently removed, thus increasing the quantity of dechlorination chemicals required. In contrast, class-leading peristaltic pumps deliver predictable, accurate metering at variable pressure, even in fluctuating process conditions. Gas locking and crystallisation issues are also eliminated. A related industrial water treatment process is pH adjustment, as water pH influences the effectiveness of disinfection. Furthermore, accurate pH control is critical to meet water standards and ensure process continuity. However, metering alkalis such as calcium hydroxide, or lime slurry, creates issues with mechanical damage to the pumps due to the abrasive nature of the chemical, while metering acids carries safety implications and can corrode pipework and equipment. Conversely, peristaltic pumps minimise pH ‘overshoot’. In addition, suspended solids are handled with no risk of clogging.

REAGENT DOSING

High accuracy to optimise yields is a prerequisite in applications such as reagent dosing. Here, peristaltic metering pumps deliver linear and accurate metering across the flow range, improving the efficiency of flotation cells and increasing mineral yields. Reagents such as sulphuric acid are hazardous and can damage pumps, but

UK FLOWTECHNIK’S REVOLUTIONARY NEW PROGRESSIVE CAVITY PUMP Accurately dispense fluids and pastes containing up to 60% fillers.UK Flowtechnik Ltd, sole agent for the UK for the Beinlich Pump, synonymous with Gear Pumps for many years has recently launched a new small-scale progressive cavity pump, the VISCO.pump®. This innovative pump has been designed specifically to enable the precise dosing of fluids and pastes proportional to speed. The VISCO.pump® can be used in many areas of industry and its pumping principle allows for precise dispensing of beads and dots as required, normally as part of an automated process. The pump is well-suited to applications such as; adhering to magnets in motors and loudspeakers, for LED strips, glob topping, dam-and-fill processes, underfilling, for sealing housings, greasing motor shafts, applying cooling paste on chips or for dispensing PU. The newly developed pump is able to accurately dispense liquids and pastes with up to 60% filler content. The dosing quantity can be set to be absolutely linear, with a dosing accuracy and repeatability of ± 1% or less. With such a linear volumetric efficiency and high predictability on delivery, this makes the pump almost “Plug&Go” when regarding the control theory, making handling and using the pump considerably easier than other pump designs and also reduces the cost of installation and commissioning. The VISCO.pump® can be retro-fitted into existing systems if required. Richard Price, UK Flowtechnik’s Managing Director, said, “The size of the VISCO. pump®, combined with its meticulous precision in continuous dosing of fluids and pastes, sets it apart from other pumping technologies currently available and we’re delighted that we now have this innovative solution which delivers continuous dosing across a broad range of applications with exceptionally high accuracy and repeatability. “It is generating considerable interest across all the major advanced engineering sectors, from aerospace and automotive, through to electronics, medical and pharmaceuticals.” “We are constantly faced with new challenges using existing pump technologies. At times gear pump technology is not the best choice for dosing and dispensing of fluids, particularly those containing materials that are shear-sensitive or containing solids. The new technology is based on the volumetric principle of an endless or infinite piston where the core components; rotor and stator form a perfectly sealed metering chamber. The eccentric movement of the rotor allows for a low-shear motion of the medium from one chamber to the next chamber without damage to the media.”

KSB PUMPS HELP AERATE ANGLIAN WATER

Pumps are big energy consumers that currently account for 10% of global electricity and many are needlessly inefficient. Today by focussing on changing to high efficiency pumps that incorporate advanced motor technology, an average pump’s energy consumption can be reduced by up to 60%. Efficiencies are a function of good pump design and not purely a standalone benefit so it is important to understand the true value of pump efficiency. This means that to achieve the highest overall efficiency the complete installation needs to be examined in terms of the entire system, as opposed to just viewing the pump in isolation and being able to deliver real energy savings with a short return on investment, of less than 2 years is now reality. By thinking beyond the pump and taking the entire pumping system into account it is possible to optimise the way pumps, drives, controls & protection, measurement and communication units work together as part of one system. A manufacturer like Grundfos, can incorporate specific demands with our application expertise, take these requirements, and translate them into state-of-theart pump intelligence - for any application. This approach that is both integral as well as encompassing the integrity of the entire system and is called Grundfos iSOLUTIONS. The need to optimise and control speed is something that will continue to gain in importance within areas such as building services, industry and wastewater applications and therefore the ability for systems to become increasingly synchronised, will also continuous to play a more significant role.

KSB have supplied two new Amerex KRT pumps with specially fabricated Duckfoot for Jet Aeration tank at Anglian Water’s Southend. The need for energy savings, improved carbon footprint and lower whole-life costs is becoming an important driver for innovation in Anglian. As a result KSB Amarex KRT duty standby pumps were installed in their Jet Aeration tank at the Southend site to replace existing pumps. KSB Amarex KRT is a vertical, single-stage submersible motor pump in close-coupled design. It is available with various impeller designs and can handle all types of abrasive and aggressive waste water in water and waste water engineering. The Jet Aeration tank was commissioned and built at the Southend site during the mid 1990’s by Anglian Water and serves two functions: Transfer of atmospheric oxygen into the liquid and the agitation of the tank contents. The Jet Aerator consists of three components: The KSB Amarex KRT pump which provides recirculated and pressurized liquid to the jets, the air blower which provides oxygen to the submerged jet at the necessary pressure; and the jet assembly itself. A twin guide rail system was supplied for installation using a specially designed and fabricated straight-pattern duckfoot by KSB Ltd. Two submersible KSB Amarex KRT pumps were installed at the outlet base of the jet aeration tank, with suction level at the pump at 0.5m, discharging to a 400mm GRP pipe down the centre of the 32m long x 12m wide tank. The KSB Amarex KRT pumps are rated at 370 l/s delivering against a static head of 5.18m and friction head of 0.91m, giving the total developed system head of 6.1m. A 200mm air pipe is mounted above the water pipe and the air/ MLSS flow is Jet Aerated through 32 nozzles. Efficient aeration is all about maximising the contact of oxygen from air with the wastewater. At the heart of the process in the Southend Jet Aeration tank are the KSB pumps. Liquid is discharged through the inner jet nozzle as a high velocity jet stream, and spreads slightly as it travels through the outer air/liquid nozzle. Within the air/liquid nozzle, the spreading liquid jet stream traps air prior to discharging into the basin. The high velocity air/ liquid cuts through the static basin liquid until the momentum dissipates creating a ‘’plume’’ of air bubbles which rises to the surface. Due to the turbulence caused by the large difference in velocity between the jet and basin liquid, the bubbles formed are quite small and create a powerful air-lift effect. Mixing is therefore caused by the liquid jet action, and by the flow of liquid/bubbles in the plume rise area. As air flow to each nozzle increases, more air will escape the plume and rise directly over the jet as larger bubbles. In order for the jet to operate properly, air must reach the nozzle properly. This means that an equal amount of air must reach each nozzle, and the jets must all be at the same elevation. Project Manager Alison Taylor of WRNI stated; ‘This Project has been delivered in an integrated collaborative approach with KSB working alongside AW Operations and the @one Alliance to meet the demands of the site in a timely, efficient and effective manner’.

After almost 40 years of continuous service the pumps at Northumbrian Water’s Great Lumley Raw Water Pumping Station had reached the end of their useful life. Pumping water from the River Wear along a two kilometre pipeline to Great Lumley Water Treatment Works, maintenance had become ever more frequent and in order to ensure the site was fit for future generations, replacement was essential. Working closely with consultants Amec and supporting the appointed contractor BAM Nuttall, SPP Pumps used its expertise and engineering excellence to provide a solution that delivered maximum efficiency, performance, operability and total cost of ownership. Four SPP LLC GT20A 4 stage dry well mounted vertical turbine pumps were specified and installed to provide a true whole-life cost solution, with SPP’s unique dry well pump suction connector ensuring that vital installation dimensions and a water-tight solution were delivered. A critical factor in the installation was the need to maintain water delivery throughout the refurbishment process, just one of the challenges associated with the project which also demanded the resolution of several key points namely: o Low net positive suction head available (NPSHa) o Severely limited space o Three fixed connection points with no flexibility- suction bend, discharge pipe and motor room floor o No discharge thrust block to restrain momentary back thrust and pump movement on start-up and shutdown Stuart Wallis was SPP’s Sales Manager (Water). He explains how the company’s depth of engineering knowledge and innovation enabled the delivery of the perfect solution: “The SPP Water Business Unit worked closely with our engineering team to develop an innovative adaptor, we then mounted and assembled the suction connector onto the clients duckfoot bend. This complex installation was completed to programme and, when commissioned, the suction adaptor met all the challenges, performed as designed and together with the rest of the installation represents the very best in engineering solutions.” For Northumbrian Water, Hedley Young, Project Manager - Investment Delivery - commented: “We have gained a solution that gives Great Lumley Water Pumping Station a more secure supply of water, more efficient and easy to maintain pumps and a cost-effective whole life installation to continue delivering the best customer service.”

FEATURE

HOW EFFICIENT ARE YOUR MOTORS REALLY? Around the world, legislation relating to electric motor efficiency is tightening in an attempt to reduce carbon emissions and damage to the environment. However, far less attention is paid to some of the practicalities. Here, Lucie Hodkova of Exico looks at how best to determine the efficiency of an installed motor.

M

otors are the greatest consumers of electricity in the world, with about 70% of all power generated being used by them. Since the Rio Earth Summit a generation ago, there has been a continuous effort to improve motor efficiency, with much effort being put into drafting efficiency standards and new testing methods for newly manufactured motors, which get gradually tighter over the years. However, this approach misses the point that there is a huge number of motors already in use around the world and their efficiency does not come under anything like so much scrutiny. So, a review of the motors in your place of work may well lead to the identification of significant improvements to your energy efficiency, carbon footprint and – perhaps most importantly – saving on your utilities bill. If you use machine tools, automated manufacturing systems, conveyors, or other ‘technical’ equipment, each of these is likely to use a number of motors. If you have air-conditioned offices, there will be motors driving pumps and fans. Medical equipment, displays, test stands, lifts, escalators, extractor fans in kitchens and laboratories are all motor-driven and, typically, their efficiency may never have been checked! All motors should have their efficiency checked and it may be best to start with those motors that are used a lot; if a motor runs constantly or for long periods, any inefficiency will have a compounding effect over time. Other motors that would be worth investigating early include those that are more than 7–10 years old, that have been repaired or rewound, that were originally installed for one purpose but have since been switched to a different duty, or those that appear to be oversized for their role. In essence, a motor’s efficiency is the ratio between the electrical power input to the motor and the mechanical power it outputs. Both types of power are measured in kilowatts or horsepower, so are directly comparable. The Energy-related Products (ErP) Directive however changed the testing method of how the efficiency has been calculated. This means that the IE efficiencies for a particular motor may be declared lower than it was under EFF efficiency rating scheme. All motors have a rated load, but most are designed so that they run over a range of loads. Typically, the load will be 50% to 110% rated load and generally, motors are at their most efficient at 70% to 80% load. The dropoff in efficiency can be very significant outside of this small optimum window, particularly in smaller motors. Fortunately, there are several quick and easy ways to check that a motor is optimally loaded. The simplest is probably to feel its temperature (be careful, it could be very hot). If it is unusually warm it is probably overloaded. The next step is to check the nameplate values on the motor and compare these with the calculated load. This will require a little technical knowledge and some interpretation. It is important to note that the stated values for the motor are

34

only true at the rated motor voltage, so the supply voltage must be checked too. Further, the total load on the motor may be the sum of several separate loads including the driven load and mechanical losses in the transmission system. At this point power factor may need to be considered. Power factor is the ratio between the theoretical or calculated power being supplied and the actual power delivered to the motor. Again using a multimeter, the power in the mains near the motor can be measured. If a power factor correction unit is present, the theoretical and actual values will be very similar giving a small power factor ratio. Larger power factor ratios must be incorporated into relevant calculations. The next step is to calculate the power output. A simple practical method to do this is to compare the rated and actual output speeds of the motor. The rated speed is calculated from the theoretical speed of a motor and is related to the frequency of the supply and the number of poles in the motor. The actual speed can be measured using a tachometer, strobe light, calculated from production rates etc. There are other methods for calculating motor efficiency; these may include special devices, computer models or complex analytical processes. In practical terms, the best answer may be to bring in an expert, who will probably be able to check ten motors in the time it would take you to do one! There is no absolute answer to the question ‘What is acceptable efficiency for an installed motor?” In each case you have to compare the current efficiency to the potential improved efficiency and work out the energy/cost implications over the duty cycle and remaining life of the installed motor. Once you have determined the efficiency of each motor you have to decide whether to accept it, rebuild it, or replace it. As a general rule, smaller motors are better replaced than repaired; it’s a cheaper option and automatically ensures that the latest efficiency standards are being met. With larger motors, the repair/replace decision is harder and unique to each situation.

OF:

HOWEVER, WE CAN DEFINE A RULEOF-THUMB STRATEGY ALONG THE LINES

· Motors that are significantly oversized or inefficient should be replaced with properly sized ones that meet current efficiency standards fairly urgently. · Motors that are moderately oversized or somewhat inefficient should be replaced when appropriate. · Motors that are properly sized but older should be replaced with modern high efficiency units when appropriate. · Sometimes, fitting a variable-speed drive to an existing motor will pay significant efficiency dividends. · Check the duty cycle of each motor: if there is a lot of idling time, consider PLC control to switch it off instead. · Some motors are deliberately oversized so that they have a bit of extra power in reserve to overcome stiction, blockages, icing, etc. A properly sized motor and variable-speed drive will provide the same effect far more efficiently. · And finally, developing a motor management strategy may be best done with the help of your expert.

FLUIDS & LIQUIDS HANDLING inc. Pumps & Valves

PFA LINED GEAR PUMPS SUIT AGGRESSIVE OR HIGH PURITY LIQUIDS When pumping applications involve aggressive liquids such as inorganic acids, bases and salts, or those that are regarded as high purity where contact with metallic components must be avoided, the Liquiflo Polygard Series pump are the ideal choice. These PFA lined magnet drive gear pumps are perfect for accurate and reliable pumping of challenging liquids such as Hydrochloric Acid, Ferric Chloride, Sulphuric Acid, Hydrofluoric Acid, Sodium Hypochlorite, Nitric Acid, Sodium Hydroxide and Chromic Acid. Available through MICHAEL SMITH ENGINEERS these pumps feature nonmetallic wetted parts and offer the important characteristics of zero leakage and therefore safer pumping. They are available in seven sizes in both DIN and ANSI flanged connections and provide flows up to 47 lit/min at differential pressures to 7 bar and they can operate at temperatures to 90ºC. Among the advantages of PFA lined stainless steel housings for these types of pump is that they do not suffer from wicking problems associated with fibre reinforced housings while the effects of heat entrapment and corresponding thermal expansion issues are minimised, as are the effects of fluid absorption. The stainless steel housings also increase the strength and durability required for process pump applications. In addition to their corrosive resistance Liquiflo PFA lined pumps provide smooth, pulseless flows so they are easy to monitor and control, also their accurate output (within +/- 2%), means wastage is eliminated. They are also designed for easy servicing so downtime for routine maintenance is minimal. Further details are available from Michael Smith Engineers Ltd, Woking, Surrey.

BELLOWS SEAL VALVE IDEAL FOR CHALLENGING APPLICATIONS Liquids handling specialists PUMP ENGINEERING offer the extensive range of Badger Meter control valves which enable the precise control of liquids and gases in the most challenging applications and demanding environments. A good example of this is their range of valves available in a bellows seal design, such as their Type 808 bellows sealed globe valve. This is an ideal choice for critical, zero-fugitive emission, high-purity or high-vacuum applications where the potential for hazardous emissions has to be eliminated. The bellows forms a flexible static seal that is leak-free, as long as the integrity of the bellows remains intact. However, should the valve fail, a set of back-up packing allows the valve to continue to operate safely until repairs can be made. The valve is available in sizes ¼”, ½”, ¾” and 1” and standard features include interchangeable trim sets, bellows packing, PTFE CV ring back-up packing and PTFE bellows gasket. The trim characteristics available are; linear, equal percentage, quick-open, or double taper. A range of accessories to enable the valve to suit specific application requirements includes positioners, filter regulators, gauges, I/P limit switches and solenoid valves. Badger Type 808 Bellows Valves can be widely used in industrial applications including research and process plants on liquids, gases or steam.

FLUIDS & LIQUIDS HANDLING inc. Pumps & Valves REDUCING ENERGY & WATER COSTS IN HYGIENIC CLEANING The food and drink manufacturing industries are large users of power and water and their associated costs impact on production and finished product costs. It is, therefore, in manufacturers’ interests to employ technologies that can reduce these costs, as well as comply with UK government energy saving initiatives. However, it is not always that easy, making it necessary for management to identify application areas where costs can be reduced. One major government initiative on energy is ESOS (Energy Savings Opportunity Scheme), this being a mandatory energy assessment scheme for larger companies with turnovers in excess of Euros 50 million and a balance sheet total of Euros 40 million/or employ over 250 people. ESOS was established by the government to implement Article 8 (4-6) of the EU Energy Efficiency Directive (2012/27/EU), with the ESOS Regulations of 2014 giving effect to the scheme. Administered by the Environment Agency, organisations that qualify for ESOS must carry out ESOS assessments every four years, with the first assessments having to be carried out and notified to the Environment Agency by the 5th December 2015. With plant hygiene being a priority for food and drinks manufacturers, expenditure on cleaning systems and water is always going to be a major concern. However, it is one area where savings can be made and will make a positive contribution to an energy assessment report. Many food and drink processing plants operate multiple sanitation wash-down systems that are sized to run at full demand at all times, with the water being re-circulated until it is required and the demand is increased. This is very uneconomic both in terms of energy consumed and water used. However, an energy efficient wash-down system has been developed by Cat Pumps that is suitable for food and drink production plants of all sizes. NEW SOLUTION Cat Pumps’ Wash-Saver pump package has been developed for centralised hygiene and sanitation cleaning systems and only uses water when it is required. The Wash-Saver is a fixed, multiple gun pressure wash down system utilising Cat Pumps’ high pressure plunger pumps in combination with a sophisticated variable speed controlled motor arrangement and control panel. As the pump remains fully primed and pressurised even when in idle mode, water is delivered at the required pressure and flow as soon as any wash-down gun is activated. This removes the need for the water to be continuously re-circulated, resulting in significantly lower energy costs and water usage. The energy savings achieved can be used as part of the ESOS assessment carried out by companies to demonstrate ESOS compliance. HOW IT WORKS Water consumption demand is managed by the Wash-Saver control panel, designed specifically to match demand with supply. The Wash-Saver uses a feedback signal from a sensor to a variable speed drive (VSD) to control the pump speed. The pump, drive motor, accessories and VSD panel come fully assembled, tested and pre-configured to match customers’ individual requirements. Furthermore, the system can be provided with an optional pre-piped water header tank, with installation into an existing centralised high-pressure pipe system being a simple procedure. The control panel can be readily incorporated into a factory automation system or linked into a local area network. As each additional gun is opened, the pump speed ramps up rapidly in response to the increased demand, and then gently slows down when no longer required. As a result, each operator will not notice any drop-off in cleaning performance when coworkers activate adjacent guns. When left in idle mode for longer periods of time, the control stops the pump completely, yet the system still responds instantly when any wash-down gun is activated. Built-in protection against dry-running should there be any disruption to the water supply, as well as automatic detection of both minor and major pipework leaks, come as standard. TYPICAL INDUSTRY ENERGY SAVING Illustrating how energy savings can be made, Cat Pumps has evidence that shows the value of energy savings that have been achieved when running its Wash-Saver system under the same operating conditions and for the same length of time as pitot tube pump wash-down pumps in a food processing plant. Running 50 wash-down guns at pressures of 50 bar and 16l/ min at an energy cost of 0.114p, the energy costs for the WashSaver were £13,497.43 and £31,693.82 for the standard pitot tube pump system, realising a saving of £18,000. SUMMARY Most large food processing and production sites have a centralised hygiene or sanitation cleaning system, many of which feature one or more high pressure pumps feeding a distributed array of wash-down guns and lances. Using high pressure water demonstrates several advantages over chemicalbased cleaning, not least of which are the effective removal of deposits and simpler wastewater disposal. The additional advantages of using a wash-down system using a high pressure triplex plunger pump is that the pump does not suffer the problems of lime-scale build up, which is common on pitot type rotary pumps, and they can be serviced in-situ thereby reducing maintenance time and costs.

The unique capability for Bronkhorst to accurately measure and control low to ultra-low flows has increasingly been called upon for research & development within the Oil & Gas industry with even the largest of global multi-nationals becoming reliant upon their expertise and experience. Clearly the precise measuring/controlling capability is important but perhaps more so is the in-depth knowledge and collaborative approach to process improvement and cost reduction. Despite a vast product range Bronkhorst have found that specialized solutions are more commonly required within this industry sector. One such solution is the capability to offer the world smallest flow range meter/controller using Coriolis technology in combination with dedicated pump technology to provide research establishments the flexibility to test and develop at laboratory scale whilst maintaining the pressures and conditions required by the Oil & Gas Industry. This same technology can then be up-scaled for field-test and ultimately production requirements. Currently, researchers are either manually dosing or using such devices as syringe-drivers to deliver the smallest of quantities of liquid into vials, vessels or reaction chambers. Both methods are tried and tested and, with years of application, are known to work adequately. However, as the need for greater precision, higher repeatability and greater reproducibility has developed so the need for finer control of the flow or dose has followed. The answer is simple - Bronkhorst not only has the ability to measure the tiniest of flows but also to directly control the addition or dosing of the additive by using a proportional control valve, an electro-shut off valve or by directly controlling a suitably specified pump. The researcher therefore receives a complete solution, fully integrated and tested, ready to “plug and play”. The total solution not only gives the user the confidence that the actual flow rate required is being delivered but also provides instantaneous readout, data logging and diagnostics. Further advantages include the ability for continuous flow mapping without, for example, the need to change out a syringe once it has run empty. This improves the integrity of data, ensures longer run times and, with the programmable software, can automate the process for un-manned experimentation. Over-dosing is reduced, the need to re-run experiments is reduced whilst cost- and time-efficiency are improved. A clear application where Bronkhorst has been successful is the dosing of performance chemicals, both within R&D and within Production. Solutions can be supplied from component level through to simple-to-use systems with the emphasis firmly based on quality, service and support. Components include the ATEX Zone 1 Coriolis Meter and Controller for gases and liquids with a flow rate capability as low as 50 milligrams per hour. More complex solutions include the Dosing Cube with programmable dosing rates, master/slave functionality and process diagnostic tooling. The use of Coriolis technology has additional benefits as the determination of density further aids process optimization. Recent shifts within the industry have further strengthened the need for a critical review of both project costings and mid- to long-term returns and the specific expertise of Bronkhorst within low to ultra-low flow applications has, as a result, seen particular focus. The capability to measure, and control, the smallest flows of both gas and liquid offers a great many benefits – no revenue streams are ever left un-measured, not one drop of additive is ever wasted and auto-calibration of analytical equipment can be refined to truly exceptional levels... A further development within Bronkhorst R&D is a multi-parameter module for the measurement of properties in gases. The module uses a combination of Coriolis, pressure and thermal technologies to derive real-time continuous measurement of viscosity and heat capacity to bring new advantages for Formation Analysis and Core Sampling Techniques. The technical specification is equally impressive, to mention but a few; accuracy is +/-0.2% of Reading, the instrument is certified to ATEX Zones 1 and 2, on-board PID control is standard, as is over-run protection and a self-learning function, the turn-down ratio is 2000:1, flow rates down to 50 milligrams per hour are easily achieved and the physical size (“the smallest Coriolis instrument inthe world”) is perfect for multiple injection points within confined spaces.

A PRACTICAL GUIDE TO IMPROVING TEMPERATURE MEASUREMENT ACCURACY By Gary Prentice, National Sales Manager Moore Industries-International, Inc. For many temperature applications, getting a high level of accuracy is vital. This new white paper highlights how plant and site engineers can ensure the most accurate temperature measurement for critical applications. It details steps that can also help end users improve the stability of their measurements and reduce calibration costs. “A Practical Guide to Improving Temperature Measurement Accuracy” shows how to select the best sensor for a particular application and ways to improve the accuracy of the sensor you choose. In particular, it details the reasons why 4-wire RTD sensors are almost always the best choice for high-accuracy temperature applications. Using 4-wire RTD sensors eliminates the errors caused by a copper lead wire. The paper also explains the relationship between classes of sensors (such as Standard and Premium Grade thermocouples and Class A RTDs) and their error rates. Along with learning how to select sensors, the paper also covers how to reduce errors caused by plant noise, using bath calibration to minimize RTD measurement errors and the relationship between remote I/O and temperature accuracy. TEMPERATURE MEASUREMENTS CAN BE CATEGORIZED INTO THREE GROUPS:

1) Those which do not require accuracy. You simply need to know if the temperature is stable or going up or going down. 2) Those which do require accuracy. Strategies in this paper will help with those measurements. 3) Those where there is uncertainty about the accuracy requirement. If the measurements in this category are on a Preventive Maintenance schedule for calibration or verification you may want to take steps to improve accuracy. The same steps we take to achieve higher accuracy also result in reduced drift and that would have a positive impact on your maintenance frequency. Improving accuracy and reducing measurement drift are often related and can have measureable results. This paper shows how to: • Select the best sensor for the application • Reduce errors caused by external environment • Reduce errors caused by lead wires • Reduce measurement errors

SENSORS AND ACCURACY

There are times when the temperature sensor is selected based on convenience, what is on the shelf or the “plant standard.” It is not uncommon to see a Type J or K thermocouple measuring a temperature that should be measured with a Platinum RTD. ASTM and IEC temperature standards provide us with sensor measurement uncertainty. If we pick a sample temperature of 500°F (260°C), the uncertainty of a standard grade J or K thermocouple is ±4°F (±2.2°C) while a Class A 100Ω Pt RTD has an uncertainty of ±1.2°F (±0.67°C).

Many process engineers and technicians prefer RTDs. Selecting the best sensor for the application greatly affects the accuracy of the measurement and an RTD is the most accurate sensor to use when the process temperature is within its measuring range. But you will need to use less accurate thermocouples when you need to measure temperatures

PROCESS INDUSTRY INFORMER September 2015

that are hotter than the RTD’s upper measuring limits. In these instances you will want to take specific steps with thermocouples to improve the accuracy of the measurement results. You can improve sensor accuracy by using thermocouples constructed with Special Tolerance (also called Premium Grade) wire. The reduced error is achieved by using wire with higher purity alloys. At 500°F (260°C), the uncertainty of a Special Tolerance thermocouple is about ±2.0°F (1.1°C). Sensor selection is very important to measurement accuracy. As stated above, a Class A Pt RTD uncertainty is about ±1.2°F (±0.67°C) at the same operating temperature. To simplify the process of choosing a sensor, you can operate from the assumption that changing from a Standard Grade thermocouple to a Premium Grade thermocouple cuts the error rate in half; changing from a Premium Grade thermocouple to a Class A RTD cuts the error in half again.

THE ROLE OF THERMOCOUPLE EXTENSION WIRE IN MEASUREMENT ACCURACY

Thermocouples wired back to a PLC or DCS must use thermocouple extension wire. Unfortunately the extension wire Figure 1. Moore Industries TCM is yet another source of measurement Remote IO (top) and Moore error. Using standard grade J or K Industries TDZ3 Transmitter extension wire also adds another ±4°F (bottom) (±2.2°C) error. You can cut the error rate by using premium grade extension wire, which has half the error rate of standard extension wire, just as with premium thermocouples. (These error figures are only true when the wire is new and “pure.”) Over time the error gets worse as the wire gets contaminated from the atmosphere

in your plant and the wire is exposed to temperatures greater than or lower than the wire tolerances. There are many instances where contamination causes even more “drift” than the original uncertainty of new thermocouple wire. If the uncertainty caused by thermocouples was a fixed offset, we could simply calibrate it out and be done with it. But when the error is in the form of drift that changes over time, calibration becomes a Preventive Maintenance program that few want to take on. Most plants prefer to avoid that extra labor whenever possible. How do you solve these problems? Start by determining how much error is caused by the thermocouple extension wire. Most people overlook this option until Plant Operations declares there is a problem or a catastrophic measurement failure occurs. We all know thermocouples fail, but it is easy to forget that thermocouple extension wire also fails. When it does, it has to be replaced. If you replace the extension wire with new extension wire, you perpetuate the same problems by reintroducing the error and drift it causes. You may have to live with thermocouples, but you don’t have to live with thermocouple extension wire – you can replace it with other solutions. Two options for replacing thermocouple extension wire are temperature transmitters and remote I/O hardware. (Figure 1) Both use copper wire to transport their signals back to the control system. Unlike thermocouple extension wire, you can expect the copper to last the life of the plant. Modern I/O products have performance characteristics similar to transmitters and can save a lot of money. You still need short sections of extension wire when you use these transmitters or I/O products. Use special grade thermocouple wire instead of standard extension wire in these cases to further minimize the error.

error of about ±4.7°F (±2.6°C). If you are trying to achieve a ±1°F (.55°C) measurement accuracy, this corrosion is standing between you and success. You can spend your life calibrating this error out or eliminate the error totally with a 4-wire RTD. Remember the voltage measurement is high impedance so, for all practical purposes, there is no current flow thru R2 and R3 and no voltage drop (Figure 3). The voltage is only measured across the RTD. R1 and R4 are never measured, thus they cannot create a differential resistance and an error. When using 4-wire RTDs, for all practical purposes, there is no error caused by the lead wire. 4-wire RTDs can have a lead wire of any length and the leads can undergo constant resistance change and still cause no measurement error. It is still important to ensure your total resistance does not exceed the drive capacity of your constant current source. Typically modern day temperature transmitters offer enough current drive to support RTD circuits that have up to 3-4K ohms of total resistance. With lead wire error eliminated you are able to focus on the sensor and measuring device to further reduce error. The only reasonable objection to using the 4-Wire RTD is that the existing legacy input card only accepts 3-wire RTDs. This is old technology and should be considered for replacement.

COMPENSATING FOR RTD LEAD WIRE INACCURACIES

Copper wire is used for RTD lead wires. If you are familiar with 3-wire RTDs you know one lead is called the compensating lead. Between copper and a compensating lead you might believe that RTD lead wire does not contribute to the measurement error. Unfortunately, this is not true. Copper wire can cause significant error in an RTD measurement because RTDs are resistors and copper wire is resistance. There are many contaminants in a typical process plant that cause corrosion and this corrosion changes the resistance of the copper lead wires. This resistance change in the lead wire can cause error. To eliminate lead wire error the solution is to use 4-wire RTDs. Here is why: When a third lead wire is added to the RTD, the measurement is made with today’s electronics by taking two voltage measurements (as shown, V1 and V2). The important thing to remember is that these are high impedance voltage measurements. For all practical purposes, there is no current flow through that third lead; thus R2 never enters into the equation. (Figure 2)

Figure 3.: 4-wire RTD diagram There is another option to consider if you are not able to use 4-wire RTDs: switch from 100Ω Pt RTDs to 1000Ω Pt RTDs. As stated earlier in this paper, 1Ω of resistance imbalance in the current carrying legs of a 100Ω Pt element produces about ±4.7°F (±2.6°C) error. If you change to a 1000Ω sensor that same 1Ω of imbalance will have onetenth of the effect. The 1Ω of imbalance error drops to about ±0.47°F (±0.26°C). While the use of the 1000Ω 3-wire RTD is a big improvement over the use of a 100Ω 3-wire RTD, it is not a panacea. When the lead wire resistance imbalance changes, that causes the measurement accuracy to change. That means you still need a calibration program to temporarily eliminate the error. The 4-wire RTD is still the single best solution because it removes all lead wire error and eliminates the need to calibrate due to the inevitable corrosion.

PLANT NOISE

Figure 2.: 3-wire RTD diagram Constant Current Source R1 R2 V1 Red = High Impedance 100 Ω Pt RTD R4 V2 V1 gives the value of the lead wire resistance R1. V2 gives the value of the RTD + R4 lead resistance. Subtract V1 from V2 and as long as the lead resistances R1 = R4, only the value of the RTD remains. This is an accurate measurement. Realize that too many things work against making R1 and R4 identical when accuracy is your primary concern. Wire gauge intolerance and work hardening varies the resistance. Even if no human error takes place during installation, corrosion constantly works against the measurement and is the main reason R1 never equals R4. So what happens if the lead’s resistances are not equal? If the resistance imbalance is as little as 1 ohm, a 100Ω Pt RTD has an

40

VFDs, motors and radios create “normal” levels of EMI and RFI which can cause errors on temperature measurements. Thermocouple and RTD signals are very low level mV signals. It does not take much noise to cause significant distortion of the measurements. If you are wiring these low level signals back to the control system please use best practices to keep noise off these signal wires by using drain wires, proper grounding and physical separation. A better solution is to convert the low level signals to high level signals as close to the temperature sensor as possible. The same amount of noise will affect high signals less than low level signals. Signals like 4-20mA, HART or RS-485 survive most typical levels of noise.

THE TEMPERATURE MEASUREMENT DEVICE AND REMOTE I/O

When you finally get to the actual temperature measurement device your ability to make significant improvements to accuracy has passed. Modern temperature transmitters and temperature I/O systems from major instrument companies have similar performance specifications. If you are trying to differentiate the finer points you might compare these specifications: • The greater the input resolution the measuring circuit can detect, the smaller the changes in the sensor’s temperature can be detected • Long term drift spec is a measure of the transmitter’s stability • RTD Excitation current should be low to minimize the self-heating error

PROCESS INDUSTRY INFORMER September 2015


• Seek the highest Input Impedance possible so that the measuring device does not draw current • Advanced diagnostics help to predict failures If you are pursuing the very highest accuracy, you have to deal with the final “as built” error in the RTD. The transmitter can be used to calibrate out that final offset error and match you to the ideal curve. Such a process delivers a typical transmitter and sensor combined accuracy of less than 0.05% of span. Putting a temperature transmitter or remote I/O near your sensor digitizes your temperature measurement. You create two more errors if you then send that signal back to the control or data acquisition system using 4-20mA: 1. D/A error occurs when creating the 4-20mA 2. At the control system, an A/D error occurs when turning the signal back to digital Using the HART digital signal is one way to avoid the conversion errors. MODBUS Serial or MODBUS over Ethernet is another option to keep the measured value digital. In summary, using transmitters and remote I/O helps: • Eliminate errors caused by thermocouple extension wire • Avoid errors caused by noise • Keeps the signal digital and avoids the analog conversion errors If you are direct wiring temperature sensors back to the DCS or PLC, it likely means that you did not want to pay for temperature transmitters for each of those data acquisition points. If you use modern remote I/O instrumentation instead, you will actually save money on instrumentation and wiring. It has the same accuracy, ambient temperature specifications and sometimes similar hazardous area certifications as you would find on temperature transmitters at a fraction of the cost. The remote I/O digitizes all the temperatures and can deliver them as 32-bit floats to the DCS or PLC MODBUS port using your choice of physical layers. Remote I/O also eliminates thermocouple extension wire and all the associated drift, errors and replacement costs.

PRACTICAL STEPS TO IMPROVE YOUR MEASUREMENTS In conclusion, here are a few practical steps you can take to improve your temperature measurement accuracy. Remember that these steps also improve the stability of your measurement which minimizes your calibration expenses. • 4-wire RTDs eliminate the errors caused by the copper lead wire • Use premium grade thermocouples and premium grade extension wire if the temperature to be measured requires the use of thermocouples • Be sure to use noise protection installation techniques whenever you have long extension wire runs • Mount transmitters or remote I/O as close to the sensors as possible in order to get rid of long thermocouple extension wire runs which are an error source, have a finite life, and are expensive to replace • Get rid of the final RTD offset error by bath calibrating • Buy the highest accuracy and highest stability transmitter or I/O you can afford • Once you have spent all that money to get your signal digital, keep it digital so there are no more errors introduced

TAKING A LIFE CYCLE APPROACH TO

INSTRUMENTATION Considering the total life cycle of your instruments will help you decide when to maintain and when to replace. Wayne Deeks, Instrumentation Service Account Manager for ABB Measurement & Analytics Service, explains what’s involved in maintaining instrumentation through its operational life and what to do when it’s time to upgrade.

A

time comes in the life of every measurement instrument when it becomes obsolete. Whilst it may be working perfectly, doing the job it is supposed to do accurately and well, the lack of any technical support or spare parts will mean it is nearing the end of its practical working life. But what is obsolescence? How is it defined and who says when an instrument has reached that status? What can be done to mitigate it and can it in fact be planned for? Like many other items of equipment, instruments go through four phases in their lives. At each phase, particular levels of support are offered by the manufacturer. These four phases are Active, Classic, Limited and Obsolete. The Active phase is the sales and manufacturing phase. At the end of this phase, volume manufacture ceases and the product moves into the Classic phase. Complete life cycle support is guaranteed throughout these two phases. The Limited phase is where this product support is gradually ramped down, ending in the Obsolete phase when no product support is offered for the instrument. Most instrument vendors keep to the same scheme, with roughly equivalent durations for each phase. On average, an instrument can have a lifespan of 10 -15 years as long as it continues to be supported and it is not unknown for users to still be using obsolete equipment that is 20 or more years old. The danger of using instruments in the obsolete phase is that there is little or no possibility of replacing worn parts. This can lead to more inaccuracies in reading, resulting in a possible degradation in product quality. Inaccuracies in flow measurement of such commodities as gas or water could reduce a utility’s profits, while large offsets in critical instruments could have serious consequences for safety or result in non-compliance with regulatory requirements. Also, a consistently inaccurate instrument could erode confidence in its ability to provide a reliable measurement, leading to staff ignoring its reading. This could prove particularly problematic in applications such as measuring the purity of water driving turbine blades, for example. Inaccurate instrumentation readings could lead to a build-up of mineral deposits on the turbine blades, causing significant pitting and other damage. In these cases, the instruments are monitoring, not controlling, and users need to be fully aware that if an electrical fault occurs they will have to replace the instrument.

GET THE DETAILS RIGHT TO PROLONG LIFE

The useful life of an instrument can be extended by ensuring routine maintenance, servicing and calibration is conducted according to the manufacturer’s recommendations. Another factor is having the right instrument that has been properly sized and specified for the application and which is able to handle operating conditions such as ambient temperature and vibration. A user should also have contingencies for when the instrument does breakdown, including having an arrangement in place to call out the manufacturer or its agents to repair a failed instrument. The response time can vary among manufacturers, who often offer different levels of response depending on the criticality of the unit. This can range from five days, down to three days or to 24 hours. Identifying the effects that breakdowns can have and identifying high risk instruments is essential in choosing the desired response time. For super-critical applications that must be back on line to comply with regulations or to avoid serious losses in revenue, a 24 hour response may be vital. An example was an ABB customer that was losing £20 to £30,000 for every 3-4 hours the instrument was down. Another is one of the UK’s main airports, which

42

employs instrumentation to measure the run-off of cleaning chemicals used on the runway. The airport needs a 90 percent up time for the instrument and every four hours off line counts as a full day, meaning 24 hour response is essential. Power stations also need this type of fast response as they must adhere to strict emission levels laid down by the Environment Agency. Tempting though it may be to specify a fast repair response from the vendor, this must be balanced against the criticality of the application, the losses incurred on failure and the increased cost of the rapid reaction. Having access to spares and keeping a stock of consumables is also a factor. It was once common for instrumentation users to keep one unit in use and another on standby, though pressure on costs has made this practice less common than it once was. Similarly, fewer users now keep an extensive spares stock, preferring their instrumentation suppliers to hold bonded spares on their behalf.Instigating a lifecycle plan means instrumentation users can plan upgrades and repairs effectively.

MANAGE THE LIFE CYCLE FOR BEST RESULTS

Understanding which phase your instruments are in and which course of action to take to maximise their life is the aim of a Life Cycle Assessment or LCA. With ABB, the life cycle assessment begins with a life cycle audit. This highlights the condition of the equipment, its revision status and necessary maintenance needs for its operating environment. This helps formulate the best maintenance programme and identifies the appropriate migration points. The life cycle audit has a number of features. The process begins with a site survey of installed instrumentation and analyser equipment, followed by an evaluation of the life cycle status of ABB and third party equipment. The condition of the products is evaluated and their installation to ISO guidelines is confirmed. The final stage is a comprehensive inventory and life cycle report, including recommendations. The life cycle audit offers a number of benefits. One of the main ones is that it provides knowledge of the equipment condition and revision status to aid maintenance planning and costing. It also helps set out a life cycle management plan to prolong equipment life and avoid premature failure, while also assisting with the development of life cycle planning and budgeting. Once the exact condition of the equipment is known, the next stage is a life cycle management service to provide effective maintenance, migration and obsolescence planning as part of an integrated programme. Essentially, the life cycle management plan implements recommendations from the life cycle audit and develops preventative maintenance schedules for installed devices based upon criticality. It also implements appropriate predictive maintenance technologies, as well putting in place any support functions needed. Its central benefit is that it enhances the condition and reliability of instruments and extends operating life. It makes the correct resources and parts available to implement upgrades, while providing lower cost of ownership and minimal disruption.

SUMMARY

Taking a rational approach to instrument servicing and replacement such as taking a whole life approach, is the only sure way to get cost-effective, extended use from valuable plant assets and in turn ensure that quality, safety, compliance, production time and revenue is maximised.

CARBON BRUSHES A NEW LEASE OF LIFE

Jon O’Brien, Application Engineer at Morgan Advanced Materials, discusses the evolution of carbon brushes and the maintenance techniques that can extend the life span, improved motor performance and reliability of these essential components, as well as providing guidance on the material choices available.

W

HAT IS A CARBON BRUSH?

Although they may differ in size, shape and technical composition, carbon brushes used in DC motors and generators all fulfil the same basic function – to transfer electrical current from a moving device to a stationary point and vice versa, within a circuit. The main function of the brush is to conduct current without interruption, meaning the point at which the brush transfers current from its surface to the moving collector is critical. During operation, a film – or patina - is automatically formed on the surface of the collector, and this is critical in conducting current and reducing friction. Carbon brushes were first patented in 1885 by Scottish inventor Professor George Forbes. They proved a more effective conductor than the earlier brushes which were made of strands of copper and frequently left deep scratches and grooves in the collector, resulting in the need for regular resurfacing. Additionally, the hard metal brushes would themselves often wear away, releasing debris which could short circuit the collector by becoming wedged in moving parts. Gauze brushes, an early alternative to copper, provided improved surface contact and reduced segment wear, but were much more expensive than their copper counterparts. The use of carbon brushes minimises sparking and arc damage at the point of contact, while the low friction characteristics and lubrication properties of carbon minimise damage to the collector (commutator or slip ring) surface, reducing the amount of wear debris that can collect within the machine. Carbon brushes are also more versatile than copper alone, as they can be adjusted for individual applications by altering the ratio of carbon to metal powder – brushes with a high metal content perform best with low voltage and high current, while a higher carbon content results in a brush ideal for high voltage and low current density. Despite the benefits of carbon brushes over their copper predecessors, friction between the brush and collector is inevitable and eventually causes wear to the surface of both. As carbon is the softer of the two, it will wear faster, and is therefore designed to be easily replaced. The life of the brush can also be affected by factors including the holder design and alignment; temperature and humidity variations; contamination by debris or lubricants; vibration; or changes in current, speed or pressure. Effective inspection and maintenance are therefore critical in avoiding both unnecessary downtime and premature replacement.

GENERAL MAINTENANCE POINTS

Routine condition-based maintenance begins with a visual inspection of the carbon brush and associated components. Brushes, holders, collectors and connections should all be regularly checked for general condition, cleanliness and contamination from excessive dust or grease. When inspecting collectors, the patina (an oxidised film which forms on the surface) should be closely monitored as this will reduce frictional wear and so improve the life of the brush, as well as minimising the wear on the collector. Brushes fitted to a freshlyturned collector are liable to wear faster than brushes running on an established patina as the patina takes a while to fully form, and this should also be taken into account during inspection. The alignment of brush holders should be measured to ensure there has been no slippage or shifting which could hasten wear and damage, while brushes themselves should be thoroughly checked from terminal to contact surface – with particular attention paid to contact faces where a smooth, well-polished surface is indicative of good performance.

INFLUENCING FACTORS

Damage to carbon brushes can occur due to mechanical, electrical or environmental factors, and inspection schedules can be designed around common faults in these areas. Mechanical problems which must be identified

44

quickly include poorly mounted or aligned holders; worn springs; eccentricities in wear patterns on the collector; and incorrect pressure. Contamination, temperature and humidity are among the environmental factors which may cause premature damage or quicken wear, and the causes of any ambient changes should be identified and rectified to prevent further damage. Poor commutation, leading to sparking, as well as a lack of a fully formed patina, are electrical factors which can lead to wear of both the brush and commutator.

VITAL CHECKS

If a brush is found to be wearing prematurely, maintenance engineers should work through a list of vital checks which will uncover the causes of shortened brush life and inform the corrective strategy. The following should be ascertained: - Current density - Collector run-out - Surface speed - Collector temperature - Humidity - Brush pressure - Amount of sparking - Duty cycle - Level of vibration during operation - Appearance of the patina/ collector film - Brush set-up in terms of whether it is correctly aligned - Spacing of brush holder - The presence of any contaminants nearby Discovering if any of these factors is beyond acceptable limits, combined with the brush life history taken from maintenance records, should lead engineers to diagnose and rectify problems, whether they are mechanical, environmental or electrical.

MECHANICAL CAUSES AND SOLUTIONS

As previously discussed, mechanical issues can cause problems such as ill-fitting brushes in the holder. If the fit is too tight, it will cause sticking which in turn will lift off the collector, breaking the current path. Too loose a fit allows movement of the brush in the holder which in turn will cause intermittent breaking of the current flow. When fitting new brushes, it is advised to bed the brushes into the shape of the collector as illustrated in Figure 1. To ensure the brushes are fitted correctly, check that brushes are free to move easily in their boxes after bedding in and cleaning. Brushes and holders manufactured to either IEC 136 or DIN 4300 tolerances should always be selected.

BRUSH HOLDER ALIGNMENT

Carbon brushes are fitted into holders which are designed to keep them in the correct position and allow the brush to run on the surface of the collector to transfer the maximum current and so deliver optimum performance. There are two main types of holders; one in which the brush is rigidly attached to a swivel arm, and the other in which the brush is free to slide in a supporting box. Slide type holders are generally

classified according to the angle at which the brush meets the collector as per Figure 2.

brush surface of the brush (Figure 6). If the brush is overloaded, it is advisable to check the brush material and ensure use of a brush with the optimum current density for the application. Low load – often evidenced on variable load motors seen in steel mills by streaking on the commutator - can potentially be overcome by selecting a brush grade suitable for a broad spectrum of loads including light load running.

Fig. 5

Fig. 6 To ensure the brush is at the optimum distance from the collector – and so prevent brush movement issues or the brush holder arcing current to the collector - the holder should be positioned approximately 2.5mm from the collector. If distance falls below 2mm or exceeds 3 mm, the window holder needs to be reset as shown in Figure 3.

ENVIRONMENTAL ISSUES AND PROPOSED SOLUTIONS

Interruption to the formation of the patina can be caused not only by mechanical and electrical issues but environmental issues such as; ambient temperature, humidity, contamination, vibration and maintenance standards – all of which can have an impact on the film formation. For the film or patina to form correctly, optimum conditions are required. Moisture is essential, with humidity levels of less than 4.6 mg/L (1.5 grains/ft3) potentially disrupting this process. Cooling air is often supplied from outside and is generally forced directly onto the collector, but problems can arise if the air is too hot or too cold. Furthermore, at low load, the collector may never achieve normal operating temperature – which will also impact on the film formation and ultimately on the brush performance.

Fig. 7

SPRINGS AND SPRING PRESSURE

The final area that can cause mechanical and also electrical issues, is that of spring pressure. To prevent inequalities the spring pressures should be the same across all the brushes in the motor or generator. Such inequalities - where some brushes are optimally configured while others are at too low or high a spring pressure – are likely to result in rapid mechanical or electrical wear, and may also cause selective action across the whole system. Due to the radial travel of the brush through the holder as it wears, it is advantageous to use constant force (CF) springs. Figure 4 shows the force in these springs is constant over a wide range of spring extensions. As the spring travels down the brush holder, the force remainconstant until it has reached 0.8 times the diameter of the coil. To optimise performance, a rubber tufnol top with a locating radius should be fitted to allow best possible location of spring with damping to reduce any potential vibration issues.

Fig. 4

COMMON ELECTRICAL ISSUES AND SOLUTIONS

Poor commutation, leading to sparking, as well as a lack of a fully formed patina, are electrical factors which can lead to wear of both the brush and commutator. This is frequently evidenced by ghost marked surfaces on the brush (Figure 5), which could indicate issues such as an incorrect neutral point or interpole problems. The neutral point should be checked with a neutral meter before any further issues are investigated. Overload, low load or varying load can also cause damage to the brushes, holders or collector. Overload current will be shown by burnt flexes or a pitted

GRADES OF BRUSH MATERIAL

The brush/ holder/ collector system plays a key role in optimising motor uptime. Ensuring continuous, even current flow is paramount and correct brush grade selection is vital to that process. Various grades are available depending on the specific application requirements. Entity in a steel mill motor, for example, a combination of issues may be present such as contamination, high temperatures, varying current loadings with periods of light load running and vibration caused from other equipment in the area. For this application, an electrographitic grade, able to cover a spectrum of current densities, coupled with a CF spring and rubber Tufnol top design to counter vibration, is a recommended solution. As well as electrographites, the most commonly used brush grades are metal graphites, natural graphites, resin-bonded products, metal impregnated products, and hard carbon/ carbon graphite products. Electrographite, used for both commutation and collection, consists of carbon which has been partially transformed into graphite by heating the material to temperatures between 2200°C and 2800°C. Electrographite is suitable for a range of applications including DC drives and AC rings, with current densities normally in the range 4 to 16A/cm2 and surface speeds up to 50m/sec. Metal graphite products are mainly used for collection, except in low voltage applications. Specifiers typically choose between copper, which is best at current densities 12 to 30A/cm2 and surface speeds up to 30m/sec, and silver which is suitable for the same speed range but for low voltage applications with good signal integrity, and varied current densities from just above zero to 30A/cm2. Natural graphite products are also suitable for collection applications, particularly Turbine Alternator (TA) exciters with steel sliprings, current densities up to 12A/ cm2 and surface speeds up to 80m/sec. For commutation applications, resin bonded products are ideal for applications where there is high contact drop (poor commutation) or in low current/ temperature applications with current densities up to 8A/cm2 and surface speeds up to 30m/ sec. At higher current densities up to 30A/cm2 and surface speeds up to 40m/ sec, metal impregnated products are the best choice. The final option is hard carbon/ carbon graphite, which is suitable for current densities up to 10A/cm2 and surface speeds up to 30m/sec in older applications or where commutation is difficult for any reason.

FOOD GRADE THERMAL FLUID ESSENTIALS With thanks from Global Heat Transfer.

It is reported that there are around 4000 companies operating high temperature thermal fluid systems in the UK and Ireland alone. Roughly one in five of these systems is used in the manufacture of food products. However, the current framework of self-governance and external audits means there is a potential for companies to use thermal fluids not suitable for incidental contact with food. In this industry report, Global Heat Transfer analyses the benefits of using food grade thermal fluid and establishes why some food and beverage manufacturers opt not to.

F

OOD GRADE – AN INDUSTRY ‘MUST’

Heat transfer refers to the transfer of thermal energy. In this process, heat transfer fluids (HTFs) act as a heat carrier between a heater and a heat consumer. This is the basic requirement of a wide range of industrial processes and the principle behind indirect heat transfer plants. Indeed, a recent report estimated that the value of the market in 2011 was $1,684 million and by 2017 this will increase to $2,557 million. A food manufacturer should source food grade HTFs that are suitable for use in food processing. Food grade fluids carry a HT-1 certificate issued by governing bodies such as NSF International and the US Food and Drug Association (FDA). Any manufacturer that wants to sell into the US food market must abide by the correct standards. In the case of the NSF, the components of a thermal fluid are compared against the NSF’s registration guidelines for proprietary substances and nonfood compounds. Based on a toxicological analysis, a HTF can then be registered as HT-1. The supply of food grade HTFs is highly regulated in Europe and companies must comply with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) and CLP (Classification, Labelling and Packaging) regulations, which refer to the classification, labelling and packaging of substances and mixtures. Failure to use FG oil in a food application can result in the loss of the manufacturer’s top tier accreditation if the EFSIS (the European Food Safety Inspection Service, part of SAI Global Insurance Ltd.) learns that an inappropriate product is being used. Furthermore, food grade thermal fluid is a requirement for manufacturers that want to supply to the top supermarkets and fast food chains in the UK, in compliance with the British Retail Consortium’s (BRC) global standards. Members of the BRC include Tesco, Sainsbury’s, Asda, Morrisons, Waitrose, Aldi, McDonalds, KFC, Burger King and many more retail giants. Thus, compliance with the standards outlined by the BRC is a must for companies wanting to reach these distributors. A list of recommended food grade HTFs

is also commonly reviewed by insurers and food retailers. With all these compliance and control standards in place, the lack of commercial awareness is surprising. At Global Heat Transfer, we still meet food manufacturers who are keen to sell to the European and US markets, but are not entirely aware of what mandatory requirements exist for HTFs. Unfortunately, on an international scale, there are still ways to get around the current regulatory framework and use HTFs that are not suitable should they come into contact with food products. For example, one such justification is that a company can choose to dispose of all products that come into contact with the fluid. The real problem is that food manufacturers are central to all the external audits and controls mentioned previously, but there is no one mechanism to ensure that food grade HTFs are used in the processing of food. Hazard analysis and critical control point (HACCP) is an internal Food Standards Agency document used to define the acceptable contamination limits for a food. But instead of using a non-toxic food grade fluid, some manufacturers may choose to dispose of all food that comes into contact with an HTF. Lastly, an insurer could stipulate the use of a food grade HTF, but confirmation that a food grade HTF is used would be based on a paper-based audit only. Insurers also assess the frequency that an HTF is sampled and chemically analysed to ensure the flash point temperature of the HTF is being managed as stipulated. However, at no point would the insurer request the HTF to be sampled and chemically analysed to validate documentation. On a final note, some companies still do not fully appreciate the costs they can incur if things do go wrong with their heat transfer system or if entire batches of products need to be discarded. Better awareness of the complexities of thermal fluid would be beneficial for food and beverage manufacturers, suppliers and the general public. Recalls of food and beverage products due to contamination concerns have risen significantly over the last decade and the associated costs can be

crippling. Not to mention the inevitable dent the incident will leave in the company’s reputation.

FOOD GRADE VS. NON-FOOD GRADE FLUIDS

Food grade thermal fluids are highly refined mineral oils designed specifically to be used in the processing of food. They are non-toxic, non-irritating and have no odour to ensure consumer safety in the event of a leak or spillage. As you can imagine, this is an essential health and safety measure in the food processing industry. Food grade fluids consist of a complex combination of hydrocarbons obtained from the intensive treatment of a petroleum fraction with sulphuric acid and oleum, by hydrogenation or via a combination of hydrogenation and acid treatment. A food grade HTF consists of saturated hydrocarbons with carbon numbers predominantly in the range C15 to C50. A recent test carried out by Global Heat Transfer illustrated that, on average, carbon residue for food grade fluid was lower than non-food grade. 1,223 fluid samples were examined - 280 food grade943 non-food grade. These were taken from 97 customers (24 food grade HTF and 73 mineral HTF) with multiple HTF system lines based at multiple locations in the UK and Ireland. All identified systems were sampled whilst performing under normal operating conditions. A 500 ml sample of the HTF was withdrawn from the system using a custom designed sampling device. The sampling method ensured a true and representative sample of the HTF was obtained. The first aspect of this analysis showed that carbon level was 0.10 and 0.23 of the percentage weight for food grade and non-food grade respectively. This reflects a percentage difference of 118 per cent (- 0.12/0.10 * 100). Total acid number (TAN) levels were also lower for food grade HTF (0.13 versus 0.18 - food grade versus non-food grade HTF). The data clearly showed mean and maximum values for carbon residue and TAN were higher for non-food grade HTF than for the food grade one. Individual data was then explored and linear analysis showed there was a strong positive relationship between carbon residue and TAN for both types of HTF. The analysis demonstrates the non-fouling nature of a food grade HTF, making it more sustainable and less costly in the long-run. HTFs suitable for use in food processing are commonly referred to as ‘nonfouling’, which means when they thermally degrade, they produce small carbon particles that are suspended in the liquid. Moreover, the carbon formations are less sticky and this reduces the extent of adhesion to the internal surfaces of a heat transfer system. It is important to remember that all HTFs undergo thermal degradation over time. At high operating temperatures, the bonds that exist between hydrocarbon chains will start to break and form shorter (commonly referred to as ‘light-ends’) and longer chained hydrocarbons (‘heavy-ends’). Both of these products have consequences for the safety of a HTF system and for HTF sampling. The build-up of light-end components is a potential fire risk because they decrease the ignition temperature of the HTF. The accumulation of heavy-ends results in the formation of sticky carbon deposits or sludge and can be monitored by analysing the carbon residue in a system. The same is true for oxidation of a HTF: this leads to the formation of carbon sludge and acids. Sludge or soft carbon will lead to a carbon coat forming on the internal surfaces of the HTF system and with time this will harden. The insulating effect of carbon means that the HTF system is less efficient: heat transfer rates are reduced resulting in longer heat-up time and lower production rates. Also, the hard carbon deposits work to form hot spots and have the potential to cause heater tubes and electrical elements in the HTF system to burn-out. The salient point is that routine heat transfer fluid analysis is the only accurate way of assessing the condition of HTFs and predicting when the system needs topping up or flushing. Ideally, all plants using heat transfer fluids should create a robust lifecycle maintenance plan that contains regular sample analysis and careful flashpoint management and thermal fluid condition maintenance. Safety can be further enhanced in food and beverage manufacturing by using non-fouling food grade HTFs that have a lower tendency to result in carbon residue than non-food grade HTFs. This will implicitly mean a reduction in maintenance and production costs and should eliminate the unwelcome prospect of discarded product batches.

CONCLUSION

Global Heat Transfer’s analysis of both food grade and non-food grade fluids revealed the former was less fouling to systems, had a lower carbon residue and lower TAN levels. This means higher safety levels, as well as lower maintenance and operational costs in the long run. Despite these obvious advantages, some food processing facilities still don’t use food grade transfer fluids. We believe food and beverage manufacturers require a higher level of awareness when it comes to the regulatory, environmental and maintenance benefits of using food grade heat transfer fluids in food and beverage applications. We believe awareness is the key to make food and beverage manufacturing more cost-effective in the long run, while ensuring companies don’t make any unnecessary sacrifices when it comes to product quality and process safety.
