Quick Guide to Updated CRC Energy Efficiency Scheme Major changes to the CRC Energy Efficiency Scheme affecting many manufacturing and engineering businesses - are explained in a free Quick Guide’ published by energy management advisers CMR Consultants . The ‘Quick Guide to the Updated CRC Energy Efficiency Scheme’ is intended to help organisations take prompt action to achieve compliance and to reduce the cost and impact of the energy legislation. CRC affects all public and private sector organisations consuming more than 6,000 MWh/year through their half-hourly electricity meters. This equates to approximately £500,000 plus energy spend per year. Between them, these organisations are said to be responsible for 10% of all UK carbon emissions. Recent changes to the CRC Energy Efficiency Scheme include the abolition of the CRC Performance League Table and revised emissions reporting requirements. Going forward, further changes are predicted, particularly with the introduction of Phase 2. Other simplifications include reducing the number of fuels participants must report on from 29 to 2 (electricity and gas, the latter for for heating) and removing the 90% rule, which required organisations to account for at least 90% of their carbon footprint. “The government has simplified the CRC Energy Efficiency Scheme, but the legislation can still impose a significant cost and resource burden on organisations”, said Dr Cedric Rodrigues, Managing Director of CMR Consultants. “There are two key areas that organisations must consider urgently, which are qualifying and registering for Phase 2 and developing a carbon reduction strategy ahead of Phase 2.” Charging for carbon allowances under the CRC began in 2012 and the tax will remain at £12/tCO2 until Phase 2 begins in April 2014. Participants are required to submit an annual report of emissions by the end of July each year.

Grundfos - the science behind fire protection Fisher Scientific is a leading supplier of laboratory chemicals and equipment who operate from a large site in Loughborough and employ 450 people. As a business they supply 170,000 specialist scientific products - many of which are highly flammable. Due to a catastrophic site fire pump failure, the company had an urgent requirement for a more robust system with better remote monitoring facilities. So Fisher Scientific elected to contact the specialist fire team within Grundfos Pumps to seek their input to design an improved solution. Following consultation, Grundfos specified and supplied 2 FM fire pumps and a Grundfos Remote Monitoring (GRM) system that included wireless systems. The new GRM system now means that any situation that may arise will be captured and communicated via a range of communication options including SMS, email and via telephone. This assurance is backed-up by Grundfos Service being connected within the GRM link. Additionally this Grundfos GRM system also offers a range of continuous monitoring surveillance options specific to this sites requirement. We all know the devastating consequences of fire but being able to install a bespoke system that not only has the ability to keep fire under control but that can also act as an intelligent fire communication hub, means that these Grundfos GRM systems have taken prevention to a whole new level.

ASCO NUMATICS HIGH FLOW FILTER REGULATORS ENABLE ASCENDANT TECHNOLOGIES TO OFFER MORE RESPONSIVE VALVE SOLUTIONS Series 342 stainless steel filter regulators reduce closing time of valves Ascendant Technologies, a specialist valve automation company serving the UK oil and gas sector, has selected filter regulators from ASCO Numatics to help improve the response speed of its valve solutions. By deploying the ASCO Numatics 342 Series of filter regulators, which have a large flow rate, Ascendant Technologies is able to meet the needs of its customers by offering a solution with a significantly reduced valve closure time. Filter regulator flow rates are critical in determining the time required to close a valve. ASCO Numatics 1 /2” stainless steel filter regulators incorporate moulded

reinforced diaphragms, which enable a flow rate up to 4430 l/min. Following performance tests, Ascendant Technologies concluded that the ASCO regulator reduced the valve closure time from 11.7 to 7 seconds. “To meet end user requirements, we needed to improve the response speed of our valve solution,” said Andy McDuff, General Manager, Ascendant Technologies. “We tested a number of filter regulators from different suppliers and the ASCO device outperformed its rivals, helping to significantly reduce the valve closing time.” For Emergency Shut-Down (ESD) applications the response time of the valve can be critical. If the filter regulator is unable to pass enough air to enable the actuator to close the valve in the specified time, then a

booster may need to be fitted. This adds to the overall cost and increases the number of potential leak points. The Series 342 is suitable for ambient temperatures from -40°C up to +80°C (-50°C for arctic conditions is available on request) and for compressed air and gases. It can therefore be installed across many industries, including chemical, petrochemical, oil & gas, refinery, power generation, pulp & paper and process plants.

TOILET PAPER MANUFACTURER INSTALLS SIX QDOS 30 METERING PUMPS � Qdos overcomes aeration problems encountered with solenoid pumps � Easy flow rate adjustment suits different chemical dosing applications � Maintenance intervals up to 4000 hours help minimise downtime The recently launched Qdos 30 metering pumps from Watson-Marlow Pumps Group are delivering significant process improvements at a Brazilian toilet paper manufacturing plant, where no less than six of these innovative ‘no valve’ dosing units have now been installed. What’s more, further Qdos orders could now result from the planned installation of a further new product line.

Crafting success São Paulo-based Manikraft Guaianazes Pulp and Paper Industry Ltd was founded as a family business in 1961. The company is today a 700-employee concern operating out of two production facilities in the city. Over the years Manikraft has brought a number of well-known toilet paper brands to the marketplace, such as the Mascot, Mirafiori and Primavera brands. In fact, the latter is now an established market leader that is exported throughout Latin America. Until recently, Manikraft used solenoid-style diaphragm pumps to dose chemicals such as additives, release agents and resins into the pulp. However, the company encountered problems with incrustation and air bubbles that compromised final product quality. Determined to improve their process, Manikraft investigated peristaltic pumping solutions. With no valves in the fluid path to clog, corrode, or vapour lock, peristaltic pumping sounded to be the perfect solution. Manikraft now needed to choose which peristaltic pump

was the best fit to economically retrofit into their system and deliver consistent quality for the long term.

Key decision The answer arrived in the form of Watson Marlow’s Qdos metering pumps, which are designed specifically for chemical dosing in industrial markets. The main benefit for Manikraft is that these high performance pumps accurately meter chemicals without the need for any valves or ancillary equipment, keeping costs to an absolute minimum - in fact, the total cost of ownership is less than that of a typical solenoid or stepper-driven diaphragm pump.

Matching requirements Qdos was considered a perfect match for Manikraft for a number of reasons, such as accuracy, repeatability, quick maintenance, and budget. In fact, maintenance intervals are up to an impressive 4000 hours at typical usage, reducing the impact of downtime. This is crucial to a company which operates its pumps 24 hours a day. Manikraft varies the flow depending on the application and needed a pump with ease of accurate, repeatable dose adjustment. For instance 90-130 ml/min is preferred for resin dosing; 5-20 ml/min for release agents; and 20-70 ml/min for additives. Qdos fits the need, offering 5,000:1 flow range and 1% accuracy which can be achieved either through the user-friendly HMI or through plug-andplay auto control inputs. As with any retrofit application, matching quality to a tight budget was important. Manikraft was familiar with lower cost peristaltic pumps, including pumps that used separate inverter controls. Though within budget, inverter driven pumps did not offer the speed range, accuracy, compact footprint, or simple operator interface that Manikraft needed. Offering an all-in-one pump solution, the right functionality

for the job, and competitively priced with solenoid diaphragm pumps, Manikraft considered Qdos the perfect solution for them. Qdos pumps also feature the innovative ReNu pumphead technology. Quick and easy pumphead removal and replacement minimises process downtime and requires no specialist tools, training or technicians.

Successive orders Upon seeing Qdos for the first time, Manikraft immediately installed a pump in their process. That first pump delivered such impressive results that a number of further Qdos pump orders followed. In the meantime, Manikraft has worked with WatsonMarlow to use peristaltic pumping elsewhere in the plant, installing the company’s new Bredel Apex high flow hose pumps for transfer of polymers and peroxide dosing.

Vacuum pumps help to save water and energy at the University of Reading The University of Reading is starting to achieve water and energy savings at its Bio Food Hall in the Food & Nutritional Sciences Department following the installation of two Busch RA oil lubricated rotary vane pumps for the vacuum circuit. According to the University’s Energy Manager Dan Fernbank, since the two pumps were installed by AxFlow earlier this year, water savings of between 20 and 30m3 per day are being attained, this being the equivalent of between 7,000m3 and 11,000m3 annually. The University’s Food & Nutritional Sciences Department is the only UK university facility with a fully equipped food processing hall and has access to many specialist analytical research tools. The vacuum circuit is a fundamental requirement for all the laboratories and the piped system runs around the building enabling the various labs to pull off moisture at specific points. “The two Busch pumps which we supplied replaced two vacuum pumps which had been operating since

the building was opened in 1985,” reports Andy Woods, Sales Engineer, AxFlow. “The original pumps had water running through them at a rate of 12 litres per minute for the purpose of cooling, but because it could not be re-circulated, the water was allowed to drain away. By calculating the volume of water being wasted and its cost to the University, a decision was taken to remedy the situation. It was shortly after this that AxFlow Windsor was called in to make a recommendation on replacement pumps.” The replacement Busch oil lubricated pumps do not require water cooling, thereby eliminating any need for water. A further attraction of this pump type is that it is more energy efficient. “We offered the University two options, a liquid ring vacuum pump with partial seal water recirculation and the oil lubricated rotary vane pump,” continues Andy Woods. “Although the second option will require regular servicing, the efficiency savings meant that this option was selected and we went ahead and removed the old pumps and installed the new ones in March.” In terms of water saved, Dan Fernbank reports that this will account for the equivalent of 3% to 4% of the university’s total annual water consumption. “In financial terms, this equates to between £12,000 and £18,000 annually and being a more efficient pump, it is also saving around £1,000 in electricity,” comments

Process Industry Informer June-July 2013

Dan. “It is therefore a major step in our drive to cut our water consumption by 10% and carbon emissions by 35%.” AxFlow offers a comprehensive range of engineering resources to facilities management, environmental and process industries. The Windsor Service Centre operates teams of mobile service engineers for on-site maintenance across the southern half of England, supported by workshop personnel and design engineering resources. “Our Windsor operation is very much geared up to providing support in the building services sector and we offer a wide range of capabilities,” says Bob Jervis, Sales Manager. For instance the repair and servicing of air-handling equipment can involve the replacement of bearings, motors, pulleys and belts, as well as the re-balancing of the fan impeller assembly. We can also carry out the repair or replacement of cooling and heating coils within the AHU’s. In addition there are extensive sales, repair, service and systems engineering operations for all types of fluids handling equipment in Ealing, Huddersfield, Durham and Aberdeen.

Tower of strength Cooling towers face a range of challenges, from contamination in the environment to the stresses caused within the machinery itself, but vibration monitoring has proved to be an extremely cost-effective and reliable way to support and protect the system. Chris Hansford, Managing Director, Hansford Sensors, explains why vibration monitoring is the driving force behind a strong predictive and preventative maintenance programme. Whatever the medium, our appetite for energy remains unquenched but the race is on among power generation companies to provide the most efficient, economical and safe renewable supplies. The desire for clean energy has led to a rise in nuclear power capacity, with over 435 nuclear power reactors now in operation and many more under construction, such as Hinkley point C in the UK. The huge upfront costs of building power stations require the most efficient possible systems to support the investment and meet our demands for energy in the most economical way possible. Our climate change targets are no longer just ideals, they are legally-binding and without robust power stations they will be much more expensive to meet. Like traditional hydrocarbon processing plants, nuclear power stations rely on cooling towers to maintain safe and efficient power generation. With the world’s demand for energy resources still rising year on year, coupled with ever-increasing demands for industry to produce cleaner, more efficient energy, the pressure to maximise efficiency in cooling towers has never been higher. The challenge for providers is to maintain safety while focussing is on low-cost running of the plants. This is where reliable condition monitoring and predictive maintenance can have significant benefits, both in terms of saving money and in ensuring that plant is safe and stable at all times. The common problem of vibration threatens to inflate energy consumption in all engineering industries but in power stations excessive vibration can lead to catastrophic failure. Vibration monitoring identifies such urgent issues as a component wearing to the point of failure, enabling engineers to predict the impending failure, schedule repairs and tackle issues in advance before the spectre of downtime damages profitability. This technology is especially critical within power station cooling towers, because they must remain operational at all times to maximise generation capacity and meet climate change targets. Within each cooling tower is a large fan system, providing forced air to the heat exchangers. The fans within are typically several metres wide and, along with the drive motors, gearboxes and associated linkages and control mechanisms, all of these are prone to vibration if alignment is not performed correctly. In cooling towers, there are many issues for the vibration analyst to consider but, increasingly, many solutions to the challenges posed. Motor access is typically not an issue, since these devices are normally out in the open; however, the problem is more likely to occur in the gearbox, where access is more problematic. The gearbox in a cooling tower is often located above a

large basin and below a large rotating fan. Clearly, any system that minimises the need to access such a hazardous point will enhance safety, uptime and overall plant efficiency and this is why so many cooling tower operators are now installing the most reliable and robust vibration sensors.

Terms & Conditions... Another issue that adds complications in cooling towers is contamination. Fans, motors and gearboxes are all subject to extreme conditions. For example, because cooling towers are often sited in exposed locations, high wind speeds and downdrafts can affect fan operation. Proximity to the sea will bring a concentration of salt in the atmosphere, while any nearby plant will cause dust and particulates to enter the system. All of these conditions will cause corrosion and damage to motor and fan units. Similarly, the position of the gearboxes beneath the fan units means that they are continuously exposed to the flow of water as it is blown down each cell. This means that vibration monitoring equipment must not only be supplied but correctly specified to resist corrosion. For example it has been known for downtime to occur because poorly specified vibration switches have been supplied failed to function due to ingress of moisture. Today, however, suppliers such as Hansford Sensors can prescribe and supply exceptionally robust industrial accelerometers with high IP (ingress protection) ratings to minimise such failure. With knowledge of the best sensor and detection technologies available today and how these can best be used, maintenance engineers can not only prevent failure but also significantly maximise machine uptime. A typical vibration monitoring solution is to monitor the motor at the drive end (DE) and non-drive end (NDE), with the sensors mounted radially to examine motor bearing condition. Sensors on the gearbox input and output shafts are also mounted radially to monitor bearing condition and fan imbalance (velocity), while the addition of an axial accelerometer on the input shaft gives a good indication of the thrust on the shaft. Vibration monitoring technology helps engineers to conveniently manage systems and exercise long term cost control across power generation plants. The level of vibration in rotary or reciprocating motion machinery can be swiftly ascertained at the point of use, while measurements

in excess of safe limits can trigger alert or danger alarms to indicate potential bearing damage. Today’s hand-held data collection devices have simplified the gathering, analysis, use and sharing of machine condition data, either in conjunction with powerful predictive maintenance software systems or as standalone units with the capability to provide on-the-spot advice.

“On or Off” - that is the question? One of the key decisions to make during the specification stage is between online or offline monitoring. Online vibration monitoring, in which the outputs are connected to protection/monitoring or PLC systems, is the preferred solution but if budgets are tight it is also possible to maintain an effective vibration monitoring programme using offline monitoring techniques. In an online system, the vibration sensor is connected to a local junction enclosure and then connected to the PLC via multicore (screened twisted pair) cable. If more detailed analysis is required, vibration modules can be installed with specific filters to suit the characteristics of the cooling towers. For offline monitoring, the local junction enclosure described above is routed not to a PLC but to a switch/connection enclosure. The engineer then conducts monitoring by connecting a data collector to the switch enclosure. Despite the challenges of environment and the stresses caused within machinery during operations, the use of vibration monitoring has proved to be an extremely costeffective and reliable solution for cooling tower operators as the driving force behind a predictive and preventative maintenance programme. From the siting of the sensors to precise product specification, expert advice should be taken on how to maximise cooling tower availability through effective vibration monitoring.

Making more of pro with s Manufacturers are tapping into the benefits more capable sensors and instrumentation can provide, writes Sherborne Sensorsâ&#x20AC;&#x2122; Jesse Bonfeld

More capable sensors enable manufacturers to drive significant improvements in process and plant efficiency, product quality and safety. But while an increasing number of organisations are recognising the need to implement more sensors, or more capable sensors within their processes and facilities, deployment often proves challenging. There are several potential challenges to increased sensor deployment. Most facilities have an existing process and physical layout, where modifications to add additional sensor capabilities could have significant impacts to safety, time and cost - all of which can negatively affect both production and the projected return on investment from the sensor programme. It is often difficult to deploy sensors without shutting down an existing process. Practical considerations include availability of power to operate the sensor, and how to transmit the signal from the sensor back to a local or plant wide monitoring system. Installing new power supply points and signal cabling to support sensor implementation can also be a significant and costly undertaking.

The wireless connection Wireless sensors - and wireless sensor networks in particular - are seeing rapid uptake in manufacturing and industrial facilities. According to analysts at MarketsandMarkets, the global industrial wireless sensor networks market will grow by almost 16 per cent annually to reach $3.8 billion by 2017, with WirelessHART, ISA100.11a, and 6LoWPAN being the major technologies employed, as well as IEEE 802.11, ZigBee, Bluetooth, and cellular (GPRS, GSM, and CDMA). A wireless sensor network consists of â&#x20AC;&#x2DC;nodesâ&#x20AC;&#x2122;, which can range from a few to several hundreds or even thousands, with each node connected to one or several sensors. This model provides a practical solution for bridging information systems and the physical world. One of the major potential benefits is that often a large number of individual wireless sensors can be monitored using a single display device, or with a wide variety of fixed base stations and hand-held readers that are already available. Wireless solutions are shown to reduce installation costs and sensor installation times dramatically. They also increase safety levels because they can often be configured remotely or prior to installation, and swapped out easily for calibration, cleaning and maintenance. Conversely, the more permanent a sensor installation, the more costly the maintenance requirement tends to be. Since a variety of wireless solutions using different communications protocols are now available, it is worth nothing that mixed installations can be more difficult to manage, where these different standards are employed. A solution based on an open format, licence-free wavelength is preferred, to ensure that it does not compromise other

systems using wireless standards such as WiFi and Zigbee. These standards are often found within manufacturing and industrial facilities, and are employed to reduce the challenges and costs of implementing proprietary solutions. Moreover, a solution that combines both wireless data transmission and battery operation with low power consumption is preferable, as this eliminates many of the potentially disruptive aspects of sensor installation and operation commonly associated with wired solutions. One example is the wireless radio telemetry inclinometer, which is seeing growing adoption in the manufacturing sector as it is ideal for permanent angle measurement installations. It is also well suited for troubleshooting or checking the accuracy of angle measurements and alignments occurring across the production environment. Several applications for this technology are now employed, including the use of such a system by a leading manufacturer of heavy over-the-road trucks in the US for accurate caster measurement of the rear drive wheels. The implementation of a wireless inclinometer in this facility improved first pass yields by over 34 per cent.

the problem is identified. Here, the mounting scheme for the sensor is a consideration, since a temporary mounting scheme (where the sensor can be used and then removed easily) ensures a fast, efficient and robust install.

Continuous improvement One of the most vital roles for sensor technology is in providing the data necessary to enable manufacturers to realise a new level of production capability. Data acquisition and analysis has become central to enabling the culture of continuous improvement and lean manufacturing to which the majority of companies now aspire. Continuous improvement not only allows them to enhance productivity and free up capacity, but also serves as a foundation for driving innovation and growth. The aircraft industry for example, is continually looking to develop new composite materials offering viable alternatives to aluminium, titanium and steel. This requires raw material production methods and manufacturing processes at different conditions to those used traditionally, which is driving adoption of more capable sensors and instrumentation throughout the production process - and also in areas where they were not employed previously.

Similarly, wireless sensors measuring flow, pressure, or temperature are proving ideal for process trouble shooting, in scenarios where manufacturers wish to monitor performance of a process in a specific area for a short period of time and then move on to another location until

In another example, metal processing, particularly the steel industry, is becoming more capitalintensive, driven by concerns regarding energy consumption, emissions, and new standards and regulation. Increased use of sensors allows a manufacturer to better control and analyse emissions, improve operational efficiency, and adhere to best practices, standards and regulations. Analysts at Frost & Sullivan valued the market for sensors in the metals industry at $600-650 million in 2011, and noted that the market was growing rapidly, with advancements in sensing and instrumentation and the agility with which

ocess and materials sensors innovation steel makers adopt and implement these improvements expected to have a significant positive impact on their operations. In addition to these examples there are of course numerous other applications that can benefit from todays sensor market development for instance: • monitoring of conveyors/material transport systems - in many cases angle can be used to ensure proper location of a material transport ingress or egress point to/from a storage container, process container, etc • safety monitoring (thinking mostly chemicals here) - ability to monitor large structures that may show some level of allowable movement as processing occurs, but be able to proactively shut down a process in the event the movement occurs outside of a preset limit (think of a vertical structure where for some reason the contents are accumulating unevenly) • process material end product/feed stock loading and unloading...barges, trucks, rail...monitoring of this process to ensure even loading and unloading, again a safety monitoring system • gravity fed systems - process steps where material is moved via gravity from point A to point B and the speed and volume moved are variable, and therefore subject to the angle of tilt of the system itself • mixing processes that involve the movement of a vessel or structure itself, rather than an internal mixing device

Even sensor manufacturers themselves can benefit from advances in sensor technology to improve their processes and realise new levels of production capability. Sherborne Sensors, for example, has a highly capable calibration system that has been in commercial operation for many years. It was upgraded recently using several types of sensors in order to deliver new levels of precision required by increasingly demanding customer applications.

Enhancing old and new Acquiring data about processes and equipment is relatively straightforward using a well implemented programme of sensors. Programmes of continuous improvement and initiatives to reduce power and carbon footprints are key drivers for sensor adoption. The opportunity to consider extending the commercial life of fully depreciated plant and machinery by retro-fitting them with sensors can be significantly less costly than building a new facility, which may not even be viable commercially in today’s restrictive regulatory environment. Manufacturers might also be able to lower operating costs through sensor implementation and upgrade. For example, by closely monitoring the performance of plant equipment and product specifications, manufacturers can implement predictive maintenance activities that ensure these costly procedures are conducted only when necessary. They may also be able to identify and address potential issues before they occur. Such an approach helps to avoid costly unscheduled downtime, as well as excessively proactive maintenance schedules.

Process Industry Informer June-July 2013

Similarly, for a relatively modest investment in equipment and retrofit of more capable sensing devices, manufacturers are able to make more efficient use of raw materials to increase production volume, reduce lead times, improve product quality, or expand the range of products they are able to produce. The implementation of more capable sensors and wireless solutions can also be of benefit at green-field sites. The initial capital outlay for the sensors would be offset by lowered future operational and maintenance costs, while the plant operator would have greater production flexibility as the plant ages and production requirements change. The use of wireless sensors almost always enhances the benefits of an expanded sensor programme, due to the reduced costs associated with the installation and ongoing maintenance of the sensors themselves. As more capable sensors are deployed, the opportunity exists for manufacturers to find even more efficient and effective ways to acquire data, analyse the vast volumes being stored, identify areas for improvement and most importantly, act on the intelligence they provide.

SAVING WASTE IN THE BOILER HOUSE By NIGEL EGGINTON - EBE ENGINEERING

Energy costs today are the highest in recent history. Today’s economic and environmental demands dictate that we get the greatest practical efficiencies from our plants. To do this we must have a basic understanding of what those efficiencies are and how we may implement them. The boiler house is the engine of the modern steam system, so it is important to make sure yours is in good working order by ensuring that vital maintenance and testing is carried out regularly. Steam plant optimisation is the overall improvement of the plant’s operation. The most common strategies used to accomplish this task include and generally focus on, the improvement of primar y equipment operating efficiency, i.e. fuel and energy savings. In heavy commercial and industrial boiler applications these efficiencies are normally found in the application of waste heat recovery equipment, systems and process automation as well as improved operating practices.

VIABILITY OF EXISTING BOILER VESSELS The departure point for any improvements concerning the boilers, with regard to adding economisers or improvements in burners, has to be the physical condition of the boiler vessels themselves. Some of the available Boiler Inspection Techniques that can be utilised are: Ultrasonic Thickness Surveys - Typically these use software and experience to gather large amounts of thickness data and transform it into a colourised report to detect wear patterns or localised loss in tube wall thickness. Radiography - Conventional and Computed Radiography can be used for information purposes such as StressAssisted Corrosion Investigation or code compliance for new installations Visual Inspection (VT) - Visual examination is often used to detect mechanical damage or wear due to harsh service conditions experienced by certain boiler types.

BURNER EFFICIENCY

Older Burners had a series of cams and levers that were calibrated to provide specific amounts of air for a particular rate of firing. Being mechanical items, these wore and sometimes required calibration. They, therefore, had to be regularly serviced and calibrated. Generally, new burners use frequency controlled motors and cams to open air vents and run fans at optimum speeds that can improve performance by up to 3%. Improvements in burner design have also shown that burners older than five years are typically 1-2% less efficient than new burners. It should be noted that any air leaks in the boiler combustion chamber will have an adverse effect on the accurate control of combustion.

Values in kW

The most common economisers are non-condensing economisers. They are heat exchanger coils‚ usually finned‚ that are located in the flue gas ducting at the exit of the boiler, through which feedwater is pumped. The feedwater is fed into the boiler at a higher temperature than would be the case if no economiser were fitted. Less energy is then required to produce steam. Alternatively, if the same quantity of energy is supplied, then more steam can be produced. This results in a higher efficiency. In broad terms a 10°C increase in feedwater temperature will give an efficiency improvement of 2%.

They are designed and operate to maintain the flue gas temperature above the flue gas condensing temperature to prevent corrosion of the flue gas ducting.

The feedwater temperature The pressure at which steam is produced The steam flow rate Boilers that have no flue gas economisers, as general rule of thumb, are typically only 88% efficient in burning fuel. A large element of the burner’s efficiency is concerned with the control of air mixing and combustion. The latest burners re-circulate flue gases to ensure optimum combustion, with minimum excess air. They are also fitted with sophisticated electronic control systems that monitor all the components of the flue gas, and make adjustments to fuel and air flows to maintain conditions within specified parameters. These greatly improved turndown ratios (the ratio between maximum and minimum firing rates), which enable efficiency and emission parameters to be satisfied over a greater range of operation. Burner technology has improved greatly in recent years.

Based upon 45 tonne / hr boiler When gas is combusted, heat energy in the form of evaporated water vapour is released up the boiler stack. This latent heat represents approximately 9% of the initial fuel energy content. The bulk of this latent heat can be recovered by cooling the exhaust gas below its dew point using a direct contact or indirect condensing economizer. It is possible to heat water to about 90°C with an indirect economiser or 60°C with a direct contact economizer. The volume of hot water produced is dependant upon the volume of steam produced and the amount of gas required to produce this steam. The fully condensing economiser requires more additional construction than a non-condensing economizer however as virtually all of the gas energy is recovered paybacks are also similar to the non-condensing economiser and are typically 2 years according to manufacturers.

The burner efficiency is related to the Boiler efficiency, simply compares energy output to energy input, usually in percentage terms:

The heat required to produce steam is calculated (using steam tables) from knowledge of:

The condensing economiser improves waste heat recovery by cooling the flue gas below its dew point, which is about 60°C for products of combustion of natural gas. The condensing economiser reclaims both sensible heat from the flue gas and latent heat by condensing flue gas water vapour (example see Table 1 below). Table 1

NON-CONDENSING FLUE GAS ECONOMISERS

Burner efficiency is based upon the combustion efficiency of the burner and is an indication of the burner’s ability to burn fuel. The amounts of unburned fuel and excess air in the exhaust are used to assess a burner’s combustion efficiency. Burners are considered efficient that have low levels of unburned fuel while operating at low excess air levels.

Boiler efficiency (%) = Heat to produce steam x 100 Heat provided by fuel 1

flue gas to the boiler feedwater. For natural gas-fired boilers, the lowest temperature to which flue gas can be cooled is about 120°C to prevent condensation and possible stack or stack liner corrosion.

CONCLUSIONS AND RECOMMENDATIONS The above graph shows the approximate fuel savings by reducing the flue gas temperature exhausted through the stack. As an approximate guide a non-condensing economiser for a 5.5 tonne boiler producing steam at 7.5 bar would cost between £24,000 to £25,000. The manufacturers claim that payback for this type of economiser is less than two years.

CONDENSING FLUE GAS ECONOMISERS The application difference between a non-condensing economiser and a condensing economiser is that noncondensing economisers are primarily used to heat a smaller volume of water to a high temperature for boiler feed water, and condensing economiser heat a larger volume of water to a lower temperature. Condensing economisers can be more efficient because they can have a lower outlet exhaust temperature and take advantage of the energy in condensed flue gasses (the Latent Heat of Vaporisation). A conventional feedwater economiser reduces steam boiler fuel requirements by transferring heat from the

enclosures

Rittal’s new free-standing SE 8 enclosure Rittal’s new free-standing enclosure the SE 8 is a standardised system with features that can be assembled efficiently. Keeping the costs of engineering and handling in check, free-standing enclosures are used in many areas of industry and in building services management. Typical fields of application are compact machinery and equipment, whose power distribution and automation components can be accommodated in one single enclosure. Unlike baying suites with frames and removable side panels, the body of Rittal’s SE 8 consists of two side panels and a roof made from one piece of sheet steel. For the user, this means that both handling and installation of separate side panels are eliminated. Depending on size, SE 8 enclosures are available as one or two-door models. One particular advantage is that due to the absence of a centre bar, doors can overlap and the 1,800 mm wide, two-door system enclosures offer unimpeded access to complete mounting plates and switch panels. Rittal’s SE 8 offers major potential savings, especially in the larger widths. One single enclosure can thus be used instead of two or three bayed ones. Thanks to the TS 8 sections on the side panels, which Rittal produce in a unique manufacturing process, the user can now easily and quickly install the complete range of accessories familiar from the baying system in the SE 8. System accessories include virtually all the products needed in enclosure configuration. Accessories range from enclosure lights through to climate control solutions. Overall, the user also benefits from the improved interior installation capabilities. Flexibility and additional space are provided by expanding on two mounting levels.

Robust diagnostics help processing facilities comply with fugitive emissions regulations Badger Meter (NYSE-BMI) have announced the introduction of the Research Control® SRD series of smart valve positioners, which deliver robust, actionable diagnostic information about valve performance and help process industry facilities comply with recent fugitive emissions regulations. Badger Meter also released the Research Control SRI series of analog valve positioners. The SRD 960 (explosion-proof) and SRD 991 (intrinsically safe) digital valve positioners provide economical and user-friendly solutions for industries such as chemical, petrochemical, water and wastewater, oil and gas, food and beverage, and pharmaceutical. An optional base model, the SRI 990, provides analog valve control with fast control behavior. The positioner’s control boards can be swapped out to upgrade from an SRI to an SRD. The SRD/SRI positioners are compatible with Research Control valves and most other pneumatically-actuated valves. The positioners are ideal for both new valve installations and retrofitting existing valves. The SRD/SRI can be used to reduce the adverse effects of on-line valve friction, enabling higher thrust and shorter positioning time. Optional limit switches can also be added to stroke or rotary actuators to serve as end positions. A key feature of the SRD is its comprehensive valve diagnostics tool, which continuously monitors for fugitive emissions due to leaks and other unintended or irregular releases of gases, to help process plants meet the ANSI/ FCI 91-1 standard and comply with U.S. Environmental Protection Agency (EPA) emissions guidelines. By early detection of fugitive emissions via SRD’s leak monitoring, process plants can immediately schedule maintenance to minimize potential air pollution from their facilities and avoid fines. The SRD provides real-time performance statistics and facilitates both proactive and reactive process management. The positioner supports methods for evaluation of valve health, operation and configuration. These capabilities, in turn, allow for predictive maintenance, intelligent alarm management, self-surveillance in accordance with NAMUR NE107 recommendations, and service management. The SRD valve diagnostic software is available as Device Type Manager (DTM) for integration into control systems based on Field Device Tool (FDT) technology. The SRD is available with different communication protocols, including analog setpoint (4 to 20 mA) without communication and with superimposed HART® signal, and digital with FOUNDATION™ fieldbus H1 or Profibus® PA communications to provide connectivity to supervisory control and data acquisition systems Mutual (FM) approval for use in EEx flameproof and intrinsically safe environments. The SRD positioner features auto-start with selfcalibration and can be operated from the local display, control systems, controllers, or PC-based configuration and operation tools. A multi-lingual, full text, graphical LCD display, in conjunction with push buttons, allows comfortable and easy local configuration and operation. The LCD display presents data in simple readable text and requires no external device or software to view alarms.

ARI-ZETRIX TRIPLE OFFSET VALVE FOR CHALLENGING APPLICATIONS

Compact, rugged, easy-to-use valve positioner

The ZETRIX design was developed and tested using the very latest generation of tools and advanced German engineering technology, resulting in a premium product triple offset valve that is permanently leakproof, durable and versatile for guaranteed isolation and control in even the harshest environments. Zetrix unites the benefits of a metal-seated process valve with all the advantages of a butterfly design. With its compact dimensions and light weight, this cuttingedge valve is very easy to handle. The triple offset principle guarantees a permanently tight seal, conforming to leakage rate A in accordance with DIN EN 12266-1. It can also be used as an isolation and control valve making it extremely versatile. Available in cast or stainless steel, Zetrix is suitable for liquids, gases and vapours in a wide range of industries and applications. It features a double-flanged connection and can be used with manual, pneumatic, electric or hydraulic actuator. “Following extensive R&D investment, ARI has developed a triple offset valve that will outlast and outperform other valves on the market,” said Nick Davies, UK sales Director at ARI-Armaturen, Tewkesbury. “The new Zetrix valve has been stringently tested and approved to firesafe ISO 10497, German clean air regulations (TA-Luft) and SIL, and is designed to meet the high performance demands of applications where long life and positive shutt-off under arduous conditions is essential it is rated for operation at temperatures from -29°C to +427°C and is available in several nominal diameters from DN 150 to DN 600 with nominal pressures from PN 10 to PN 40.”

The high specification, yet competitively priced Type 3725 Positioner available from control valve specialists SAMSON CONTROLS is a logical development of Samson’s proven range of Series 373x units and provides a compact and rugged, easy-to-use device. In many of today’s process control applications the preference is for ‘smart’, multi-function, digital positioners and it’s often the case that the features in these devices remain redundant in use. In fact, a simple, self-calibrating positioner is ideal for less sophisticated control requirements and the 3725 unit has been developed for these situations. It is ideally suited for precise and reliable control of small or large flows occurring in food processing, pulp and paper or bottling plants. The Type 3725 unit features the best of the proven Samson 3730-1 / 3760 positioners by combining the ‘smart’ features and LCD with an attractive, yet rugged black, UV-resistant polyphthalamide housing and transparent blue polycarbonate cover. Data input and start-up is a simple process thanks to auto-tuning, while position sensing is contactless, performed using an AMR sensor. This method allows greater flexibility and enables the device to remain insensitive to vibrations, such as those generated by steam hammer. The new 3725 positioner is designed to be used with Samson’s family of diaphragm operated valves, and can also be Namur rib mounted for travels up to 50mm as well as fitted to rotary actuators with VDI / VDE 3845 mounting. The 3725 positioner represents a smart, easy-to-use compact unit offering exceptional reliability at the most competitive price.

MORE POWER AND INFINITE CONTROL FOR DRUM EMPTYING PUMPS The Finish Thompson range of drum emptying pumps is now available with the option of a new high performance, variable speed electric motor which provides 650 watts of continuous power combined with infinitely variable speed control. The M5V motor is 40% more powerful than comparable units and this helps to eliminate problems associated with heat build-up resulting from overloading or voltage fluctuations. Available from pump specialists MICHAEL SMITH ENGINEERS the new M5V motors are designed for use with the popular PF, TB and TBF series drum pumps. These new motors incorporate an improved bearing retaining system which eliminates any chance of movement and have larger threads on the motor shaft coupling to help compensate for increased torque. The new speed control system features a robust circuit board mounted potentiometer which uses spade connections to make replacement easier and a resistor circuit which prevents premature failure due to arcing. Also, although usually never required, the carbon brushes can now be replaced. The infinitely variable electronic speed control means fluid flow can be precisely controlled, while the double wall motor housing minimises noise and vibration and a downdraft cooling system helps contributes to extended motor life. These new motor options further extend the capabilities of the established range of Finish Thompson drum pumps which are ideal for transferring many liquids, including corrosives, solvents and viscous fluids. Models are available to handle capacities up to 150 lit/min and viscosities up to 100,000 centipoise.

calibration Minimizing system integration risks with the Beamex Business Bridge Beamex minimizes system integration risks by introducing the Business Bridge - a standardized, but configurable software solution for connecting Beamex CMX calibration management system to an ERP/CMMS system. Integration of various independent IT systems is a requirement in almost any business these days, but many times system integration projects are considered costly and risky, as staying within the original project budget and timetable can be a challenge, specifications and scope of work keep changing constantly during the project and system maintenance of a finished, highly customized integration solution turns out to be difficult and expensive. Beamex minimizes these system integration risks by introducing the Business Bridge - a standardized, but configurable software solution for connecting Beamex CMX calibration management system to an ERP/CMMS system. Mr. Pekka Videnoja, Product Owner of the Beamex Business Bridge solution explains “Many of the common system integration risks relate to the fact that system integration typically requires software development, customization or configuration on both ends of the integrated system, the calibration software and the ERP/CMMS system. We are aiming to minimize these system integration risks by offering a solution where the integration part related to the calibration software is based on a standardized, but still configurable solution”. Having a standardized integration solution brings many benefits. Due to a standardized solution, a system integration project requires less customer-specific software development wmb-611_Layout 1 30/01/2013 11:36 Page 1 work. This means quicker and more reliable delivery. A

standardized solution also means availability of long-term software maintenance contracts with regular software updates for software evolution and helpdesk services. Availability of long-term support contracts also decreases IT system lifecycle risks. The Business Bridge is therefore a safe, less risky and future-proof solution for integrating calibration system with an ERP/CMMS system and the integration project can implemented more quickly and accurately. Jan-Henrik Svensson, VP Sales & Marketing of Beamex explains, “Having a safe and less risky system integration solution with long-term maintenance capability is appreciated in many of our regulated customer industries, such as the pharmaceutical, energy as well as food and beverage industries”. The main purpose of the Business Bridge software solution is to provide a transfer channel for sharing instrument, work order and basic calibration data between the calibration management and ERP/ CMMS systems. System integration itself is beneficial in several ways. Firstly, productivity may increase significantly due to system integration, as data needs to be entered and kept up to date in one place only, instead of manually re-keying the data into two or more separate systems. Secondly, because data needs to be entered only once, human typing errors Beamex Business Bridge

Beamex Field Calibration and delays related to manual re-keying of data are minimized. The Business Bridge solution is available for integrating Beamex CMX calibration software with several of the leading ERP/CMMS systems used in the processing industry. As a software vendor, Beamex is able to offer all key elements of a system supply project, including calibration software licenses, services required for supplying an integrated system (such as consulting, project planning and management, software configuration, installation and training) as well as system support and maintenance programs.

A New Defining Mo Product Lifec In a world of sound-bites and slogans, PLM’s flexibility defies the quick sell especially now cloud computing has made possible a new affordable, easy-touse version. However could this be its strength, rather than its weakness? Colin Watson, corporate director of Symetri, believes the solution’s value lies in its flexibility and those implementing the solution will be the ones to define it - in their own terms. Is the Time Now Right? The early promise product lifecycle management (PLM) held when introduced to the manufacturing market 30 years ago has not been realised. Old-style PLM never filtered through to smaller manufacturers. Solutions were difficult to customise and were usually expensive and complex. Recently, the software developer and vendor, Autodesk identified that using cloud technology, PLM could become a more flexible, useable and affordable version of its old self and introduced Autodesk PLM 360. For manufacturers across both the batch and continuous process industries, the benefits of the approach in terms of streamlined product development, higher project and process visibility and reduced costs are perhaps particularly compelling but the solution can brings benefits and advantages to all types of businesses. Symetri was the first Autodesk partner to be named a PLM 360 specialist. However, this article explores the issues surrounding PLM adoption rather than discoursing on why manufacturers should buy a particular solution. To help provide a broad, accurate market view, Symetri recently set up a roundtable discussion on these issues with a small group of clients. Most were manufacturers

but the group also included an architect interested in using PLM in the world of construction where the increasing use of off-site fabrication is strengthening ties between architects and suppliers. Attendees had much in common; they had all been relatively early adopters of 3D digital design software and were willing to evolve their businesses to match changing conditions. They all represented small businesses with a turnover of less than £30 million - and as such had never previously been in a position to consider investing in traditional PLM. Symetri wanted to encourage them to talk freely so agreed not to name them here. However, all the quotes throughout the article come from them, unless attributed otherwise.

What’s This Got To Do With PLM? Manufacturers, and particularly those in the process industries where the focus is always on optimising continuous or batch processes have been searching for ways to become leaner for decades. The supply chain revolution of the 1990s onwards helped trim away any slack and most believe they have little left to give. Many dinosaurs of business have already become extinct, but smaller organisations can be more flexible and adapt more rapidly to change. All Symetri’s roundtable guests had demonstrated foresight by adopting new

Process Industry Informer June-July 2013

oment for cycle Management technologies and processes such as digital prototyping and design data management. Yet they are wondering where they can go next to become even leaner and more competitive. Meanwhile, there is one further development fundamental to the use of a new kind of PLM to address all these challenges - the cloud.

The Outlook is Cloudy In the design world, the impact of cloud computing could be profound. Designers need increasing computer power to visualise, simulate and analyse complex data-rich 3D models - yet, investing in high performance computers can in the short term cancel out some of the economic gains of digital prototyping. Taking tasks to the cloud eliminates the need for this capital investment. Instead cloud space can be paid for on an ‘as-needed’ basis out of an operational budget. If the cloud can make design tasks, lighter, easier, faster and better, it holds great potential for applications such as PLM.

What Manufacturers Need Now “I know what I want, but I can’t do it yet.” PLM in some form may be able to help - but what exactly do today’s manufacturers want from it? All businesses at the roundtable said they felt the pressure to respond to these global trends. “If we stand still we will go out of business,” was a typical comment. They agreed digital prototyping and design data management had delivered significant cost and productivity savings. But they were still facing three main further challenges: • Re-use of data: All those present design and manufacture bespoke products as part of their portfolio, so the ability to re-use and adapt existing data is paramount to making this customisation efficient and viable. When designers hit on a product people want to buy, they want to recreate it - or at least the core of the product that can then be modified to fit individual customer needs. Problems arise when they need to find the original bill of materials and the part numbers that first helped create that magic. They need an organised way to collect information and piece it together, instead of starting from scratch every time. • Sharing knowledge: There was a consensus that, while a good design data management system is useful for bringing together all the engineering and production elements, it still leaves out the marketing, innovation and creative side of the business model. There is still a big divide between creative and the engineering minds. There was also an overriding view that PLM should be able to capture not just data but the knowledge surrounding it. This would help maintain the integrity of the design and avoid diluting the ‘magic’ that made it a success in the first place. • Anywhere, anytime information: Workforces are increasingly disparate, with teams working in multiple global locations. Without a single, integrated source of totally current, accurate information, errors are almost inevitable. Even a small mistake can

create a major crisis when perpetuated unchecked throughout an entire project. Likewise, managers need fast access to correct figures to make the best possible decisions.

How Do We See PLM Now? There still seems to be uncertainty as to whether PLM is just a database, a process, a business model or a business enabler. It was agreed that in its physical form, PLM is basically a relational database, but its power comes into force when it has been designed to fit an individual business with data and knowledge entered. PLM’s flexibility and all-encompassing nature makes it more difficult to sell quickly. However, in reality this is its key benefit. Its basic function is always the same, but when it comes to the rest, the potential for customisation is part of its value.

Next-Generation PLM While Autodesk’s cloud-based PLM 360 is different from traditional PLM, it delivers all the benefits, without the downside. For a start, because it is paid for as a service - and then only when needed - there is no need for substantial capital expenditure and all the decision-making meetings this involves. It can be switched on instantly via the internet and off again if no longer needed, so can be used for specific projects only if required. Maintenance is carried out by the vendor and upgrades are automatic. This simplicity and affordability means SMBs are no longer excluded from the advantages of PLM. But do these benefits address the issues raised by those at the roundtable? Autodesk PLM 360 is made up of a range of building blocks or apps which can be used according to a user’s demands. These cover all product-related functions from project management and engineering to sales and marketing, and can be easily customised and integrated with existing business systems. Integrated and centralised data and knowledge can be accessed from any location and on any device. So for example, if engineers in a company’s Mumbai office

Process Industry Informer June-July 2013

need to design an original piece of machinery quickly, they can re-use designs of components previously created in Manchester. If knowledge has been captured as well as data, when they need to modify any of these, they can learn why a valve or pump was put in a certain position in the first place to avoid an expensive error.

Conclusion Unlike old-style PLM today’s PLM is affordable and light, yet has the potential to transform, especially when it fits seamlessly into a company’s workflow and integrates with other enterprise systems. The benefits for manufacturers across the process industries where it offers the potential to radically transform previously fixed or static processes, are likely to seem particularly compelling but in a few years’ time it may well be unthinkable for a manufacturer not to have PLM. But will it still be so difficult to define? If so, this could be a sign of success, demonstrating that businesses are taking the technology and moulding it to suit their own demands and challenges.

Process Safebook 1: Functional Safety in the Process Industry A new publication from Rockwell Automation looks at the principles and standards relating to safety in process applications and discusses how to implement effective solutions. Process Safebook 1 - Functional Safety in the Process Industry’ has been published by Rockwell Automation to provide its customers with an overview to functional safety and guidance in the application of IEC61511, the process industry specific implementation of IEC61508. IEC61508 has already been hugely influential and will continue to be the basis of modern safety standards and legal frameworks, so it is essential that personnel with responsibilities at any stage of the life of a safetyrelated system should make the effort to understand it. It covers the safety management of electrical, electronic and programmable electronic systems throughout their lives, from concept to decommissioning and brings safety principles to the management of systems, and safety engineering to their development. At its core is the principle that, in safety planning, safety goals based on risk assessment should be set, and then that the rigour of management and processes should be appropriate to meeting them. This makes the standard goal-based rather than prescriptive, and means that compliance with the standard does not exonerate users of any blame in the event of a safety problem. According to Keith J Kirkcaldy, author of ‘Process Safebook 1’: “The book was originally aimed at sales engineers and designers within Rockwell Automation, to help them understand some of the basic concepts that customers typically ask for; the objective being the provision of cost-effective solutions to their requirements.” The publication evolved from a local, internal publication to one that spread throughout the global organisation. It has now become available as a published book to customers and System Integrators. “It has been written in such a way that it clarifies the terminology and jargon and uses simple language illustrated with examples taken from our own experience,” Kirkcaldy explains. “It shows that compliance with the standards is not just about calculation and analysis and meeting quantitative targets, but also stresses and shows the importance of

competent management and implementation. It shows compliance is not a paperwork exercise with the objective of producing documents but, instead, it is about making sure that adequate information is available.” The book gives an overview of many facets of process safety including, but not limited to: • Safety Lifecycle • Hazards and Hazard Identification • Risk and Risk Reduction • Determining SIL Targets • Allocation of Safety Functions • Reliability Techniques • SIL Verification • Functional Safety, Assessment and Auditing ‘Process Safebook 1’ is just part of the total safety offering from Rockwell Automation, which also includes a comprehensive portfolio of process safety solutions and services. The company also offers similar guidance, products, solutions and services for machine safety. ‘Safebook 4 - Principles of Machine Safety: Legislation, Theory and Practice’ is another book available to order or download. It covers the principles, legislation, standards and application of machine safety. Recognising the impact that safety has across many industries, as well as the challenges and opportunities its customers face, Rockwell Automation has put significant budget and resources behind a strategy aimed at assisting companies to address safety legislation. From white papers and videos through technical publications to machine-level software and library files, Rockwell Automation is your one-stop choice for all things relating to safety - especially if you want it to work for you rather than against you.

ROTATION HANDWHEEL INTERLOCK The MRL Multi Rotation Lock from Netherlocks has been thoroughly tested and awarded the Fire Test Certificate according to ANSI/API and ISO standards. This means that customers can be assured that even in the event of a fire it will continue to function safely as intended, and will not cause additional disruption to the normal procedure of operation afterwards. The interlock was subjected to temperatures of nearly 1000°C for around 20 minutes, and after cooling back down functioned correctly to safely lock and unlock the handwheel valve according to specification. The test, performed by Yarmouth Research and Technology, LLC, found the MRL to be compliant with ANSI/API Standard 607 Sixth Edition - 2010 and ISO 10497:2010. During the test the lock was burned with one key in the lock; after cooldown the lock remained securely locked unless both keys were inserted, whereby it unlocked and operated smoothly as intended. Netherlocks’ MRL is an interlock for multi rotation handwheel -operated valves. Following the interlocking principle, it only allows the handwheel to be turned when two keys are inserted into the lock, ensuring that it can only be operated when it is safe to do so. For example, key 1 might only be released when a relief valve has been opened, thus making it safe to close the main process valve. Once closed, it will release key 2, which can then be used to unlock the next stage of the operation, ensuring compliance with safe procedures. For more information contact Netherlocks BV, J.

MAINTENANCE

TANK CLEANING

Power of ptfe enhances tank cleaning The HydroWhirl Poseidon range of PTFE tank cleaners available from BETE Ltd has recently been enhanced with addition of new models and flow rates as well as improvements in the overall design. The PTFE material of construction ensures that the design is not only hygienic but also highly resistant to corrosive chemicals, so it can handle powerful caustics or the cleaning of acidic environments. However, the biggest advantage of the reengineered PTFE design is the slower rotation speed. As the head turns more slowly than metal equivalents the dwell time for the cleaning spray is higher and results in a concentrated spray action against internal surfaces of tanks and vessels for effective removal of scum rings and tougher residues. This also means that the Poseidon delivers more cleaning power per litre of fluid than 316 stainless equivalents making it the ultimate tank cleaner for mid-sized, hygienic tanks. The HydroWhirl PTFE nozzle provides complete 360º omni-directional coverage and is also designed for quick and easy disassembly, inspection and reassembly using basic hand tools, so downtime is minimised. These new flow rates and slower rotation speeds means the HydroWhirl Poseidon range is particularly effective for cleaning tanks between 0.5 and 7 meters in diameter. It is ideal for food & beverage applications as well as for corrosive chemical processing tanks.

New on-line PV calculator from Status

NEW WHITE PAPER DISCUSSES O2 ANALYSIS IN COMBUSTION PROCESSES

Status Instruments has launched a simple calculator available on its website to enable process engineers to easily calculate the conversion to and from electrical input and the output Process Value (PV) of a control system. By entering the input value in mA or volts the calculator will tell the user the Process Variable (Deg C, Bar etc) for the defined configuration. It can also be used to obtain the input value in mA or volts by entering the output Process Variable (Deg C, Bar etc). “With any signal conditioning unit or transmitter, knowing the relationship between the electrical input (4 to 20) mA or similar and the process value (PV) °C, bar, L/min etc. can be essential in establishing the correct operation of a control system but it can be a laborious task to manually make the calculation. Our new calculator, available on-line, will cut the time and effort normally needed to make this essential calculation,” explains Status Instruments’ Managing Director, Ian Pullin. Status has also added the calculator to its free product configuration software. The new PV calculator can be found at http://www.status.co.uk/calculator.aspx

Once almost the exclusive domain of zirconium oxide analysers, tunable diode lasers (TDLs) are quickly becoming established as the best technique for O2 analysis in combustion processes. Traditional techniques can suffer from variable performance and short sensor lifetime making the reliability, performance and speed of TDLs an attractive alternative.

HONEYWELL INTRODUCES ADVANCED TECHNOLOGIES TO SHAPE THE FUTURE OF PLANT CONTROL ROOMS Improved Cyber Security, Collaboration and Wireless Among New Technology Demonstrations at HUG Americas 2013 Honeywell (NYSE: HON) recently introduced several new technologies that will transform control rooms of the future, including an advanced dashboard to help industrial plants better manage control-system cyber security. The Cyber Security Dashboard is among several advancements being demonstrated for customers at the recent 2013 Honeywell Users Group (HUG) Americas Symposium in Phoenix. Other new control-room technologies highlighted at the event include the Experion® Collaboration Station with expanded capability, the recently announced Premium Platform for Experion Virtualization Solutions, and the newest version of Honeywell’s OneWireless™ Network. Additionally, the company previewed a futuristic console for its Experion Process Knowledge System (PKS) Orion platform that reduces operator fatigue with an improved, ergonomic design featuring a larger display and new alarm lighting. Honeywell expects to launch the Experion Orion Console - which was designed based on input from operators - with the platform’s next release in 2014 to provide better mobility for operators while improving situational awareness. “In many ways, the control room of the future won’t be limited to the control room at all, and that concept is perfectly illustrated through technologies like OneWireless, because it extends the control room to the field,” said Jason Urso, chief technology officer, Honeywell Process Solutions. “At the same time, because we expect increasing connectivity, we’ll see a greater need for cyber security management systems like the Cyber Security Dashboard, and collaboration solutions like Experion Collaboration Station. These solutions complement each other to improve overall plant safety, reliability, efficiency, and sustainability.” The common link between all of these solutions is the ability to help make control-room personnel

more quickly aware of what’s happening in their facilities, including: • Cyber Security Dashboard - In industrial environments that are increasingly comprised of open systems, the Cyber Security Dashboard helps simplify the task of keeping automation systems up-to-date with cyber security requirements. The dashboard consolidates all data onto a single view for better visibility, and it allows users to easily drill down and access more-detailed content such as graphics, trends, documents and applications. Its advanced analytics allow the creation of customized alerts that advise personnel to take actions such as updating anti-virus protection, managing patches, and other ongoing cyber and network security-related tasks. Honeywell is previewing the Cyber Security Dashboard with customers in Phoenix and expects to roll out the tool globally in early 2014. • Experion Collaboration Station - Experion Collaboration Station enables faster responses to both routine and emergency situations by displaying a common view of how distributed assets at multiple locations are functioning. This allows plants to rapidly establish communication among centralized operations, field operations and operational specialists in separate locations. This tool is especially wellsuited for production sites with distributed assets such as offshore oil and gas operations, pipelines, and large refineries with centralized control rooms. • OneWireless Network R220 - OneWireless Network is a universal wireless network that can simultaneously accommodate thousands of field devices to form everything from a simple field instrument network, to a completely integrated plant-wide, multi-application network. The new OneWireless Network Software

R220 introduces a new interface for the Honeywell Enraf SmartRadar Flexline, which enables the device to communicate with the Honeywell Enraf Entis Pro tank gauging system, as well as the Experion Process Knowledge System platform. This allows storage terminal operators to cost-effectively improve their operations with reliable inventory data available in the control room. Operators can also generate recurring yearly productivity gains of 10 percent or more through loss-control and storage-capacity optimization, and improve workforce efficiency with smart mobile applications. Other enhancements include a redundancy feature that allows facilities to reliably use wireless for applications that require measures to prevent single points from causing a system-wide failure. • Premium Platform for Experion Virtualization Solutions - Leveraging blade server technology, Honeywell’s new solution is customized to the specific control applications needed by the customer, making it a turnkey virtualization solution. Premium Platform reduces setup time by up to 90 percent, generates up to 40 percent more energy savings and has 22 percent greater density than alternative virtualized server platforms. In addition, the platform has a longer lifecycle, reduced facility footprint and remote management capabilities in a package that is preconfigured, saving time to deploy.

JUN/JUL 2013

Diverse expertise our industries is SHAPA. A glance at the product finder in the newly configured SHAPA website www.shapa.co.uk will immediately indicate the extent of equipment and services available from a diverse range of companies. The fact that membership has survived all recessional and other pressures over the years is testament to this. Membership has consistently exceeded one hundred companies and organisations for many years. Very many companies have enjoyed SHAPA benefits for several years and there are still founder members extant.

Changes and achievement... Like any company, club or association, SHAPA is a company of committed people, who give their time voluntarily and enthusiastically to run the General Council and the two sub-committees looking after the marketing and technical activities and driving progress to enable all member companies to be equipped to compete. This year we have welcomed a new Chairman in the person of Peter Guttridge, well known and respected within our industries for many years. Following the retirement of our General Secretary John Whitehead after more than a dozen years of splendid service, we are very fortunate to welcome his successor David Green, whose engineering and marketing presence will also be well known to many of you. We once again thank John for his work with SHAPA and wish him good fortune for the future and look for ward to working now with David. SHAPA also recognised Ian Blackmore with an inaugural

The Solids Handling & Processing Association has now begun its fourth decade of continuous progress - hearty congratulations to all concerned and doesn’t time fly! Well, it is very easy to become self congratulatory, but unfortunately at the risk of losing sight of the main purpose of our existence. Perhaps SHAPA exists solely for the benefit and development of its members - this would be an overstatement and missing a crucial point. So, what is the real purpose of SHAPA and how has it survived recession and successive wind changes imposed by successive governments over the years? There is clearly something driving this success and that is, or more correctly, they are the end user customers who rely on the expertise and practical competence of their manufacturing and contracting suppliers. Plant owners and operators may well benefit from choosing suppliers who are members of SHAPA. We are generally all in agreement that the application of science serves more reliably and predictably than “black art”, but from the distant past there has been an element of the “black art” in powder and granular material handling and processing. Fortunately, collective education, technical knowledge and experience have ushered in a soundly based scientific approach to these disciplines. Of course, it would be very difficult to achieve all of this in isolation, however large a company may be. So, by sharing practical and theoretical engineering knowledge amongst like minded companies, quicker progress is possible, guesswork may be eliminated and “industry standard” solutions may be developed, upon which individual companies may build their particular advantages and inject cutting edge ingenuity. Larger installations may be overseen by engineering managers or consultants who require a cohesive set of equipment that performs many tasks, which of necessity will be procured from several companies with individual expertise, to deliver a truly “turn-key” solution to the end user. Compatability of equipment from intake chutes, batch storage containers through to dust-free bagging and out-loading requires co-operation throughout the process. This means implicit (and explicit) trust amongst the manufacturers and suppliers, knowledge of the machine functions upstream of and downstream from any piece of process equipment supplied and in particular how one element will interact with the next. Controls and safety protocols must recognise and take account the operating conditions of surrounding equipment - and so on until all the finest detail is complete. All of this is clearly desirable and indeed essential to maintain end users in a competitive position in their own market place. Furthermore, there should remain scope for later improvements as new techniques and better production equipment are developed and become available. Now, all of this may be more readily achieved if the specialist companies involved can work together successfully, even better if they actually know each other and have worked together previously. The success of technically demanding, or indeed any high volume plant contracts may be enhanced yet further if the engineering managers or consultants employed by the end user know that their selected manufacturers and suppliers can demonstrate that they have access to all the best relevant technical, commercial and legal knowledge. With so many end user industries making use of bulk storage, handling and processing machinery, to cope with a myriad of powder and granular material species, exhibiting truly diverse properties at all stages of storage and processing, this is a big ask indeed. This, however, is the real reason that such companies join a technically based trade association and the only major UK based trade association serving the whole range of

3D, NON-CONTACT LEVEL SCANNER FOR BULK SOLIDS Accurate and reliable level measurement of bulk solid silos, especially where extremely dusty environments create unique challenges for traditional level measuring devices are well documented. However, the introduction of a new and extremely competitively priced 3D scanner brings an affordable solution specifically for bulksolid silos. The APM RL 2000 is the latest offering from level and flow instrumentation specialists ALLISON ENGINEERING and provides real level measurement based on multiple level readings. The ATEX certified RL 2000 provides accurate and reliable non-contact, dust penetrating level measurement for the most demanding environments, including flour, cement and biomass materials. It is particularly effective on tall, narrow silos where conventional level technologies fail. The RL 2000 utilises 3-headed, low frequency (2.7 kHz) transducers which scan the stored product profile to provide operators with a 3D map of the silo. This level of accurate information helps operators to identify both the total inventory and also the product profile which ultimately contributes towards production improved efficiencies and cost savings in stock control. In summary the RL 2000 represents a level control instrument which is extremely competitive with other high specification (and higher cost) radar-based devices and which Allison Engineering is offering on a free-trial basis.

Accurate Feeding and Discharging The GYRO EX Bin Activating Feeder/ Discharger is a bin discharger and an accurate feeder, with up to a 100 to 1 turn down ratio, all in one piece of equipment. It produces a controlled gyratory motion to positively withdraw granular materials from bins, storage silos and hoppers. The GYRO EX bin activating feeder/ discharger uses a radial force to create a uniform circular motion on both the upper activation cone and the lower discharge cone. The stored material load is completely supported by the upper bin activation cone, which has a discharge angle less than the discharge cone. This means all material feeds faster from the lower discharge cone than from the upper bin activation cone, preventing the head load from compacting material in the lower cone as sometimes seen in traditional vibrating bin dischargers. http://www.krausvibratory.com/products/gyroex.html For more information contact Dynamic Air Ltd, Milton Keynes, Buckinghamshire, United Kingdom Tel: +44 (0) 1908 622344 E-mail: sales@dynamicair.co.uk Web: www.dynamicair.com

RAPID RIBBON MIXING FOR TATE AND LYLE FROM JOHN R BOONE LTD John R Boone have supplied a new, high-specification, easy-clean Helical Blade mixer to Tate and Lyle’s food ingredients factory in Mold, North Wales. The new 250Kg capacity mixer has been constructed to meet the factory’s stringent hygiene and safety standards in stainless steel, with ‘u-trough’ adaptations for rapid discharge, lager batch sizes and full-width top doors for easy cleaning that include special safety interlocks.

Tate and Lyle manufacture highpurity food additives and ingredients in hundreds of different types, including some made to the highest Kosher and Halal standards. Therefore when they were looking at replacing an old mixer their key objectives included improving the ease of cleaning and speed of changeover. John R Boone have a great international track record with Tate and Lyle, with Delta Blade high shear mixers already in place in Mold, Lubeck in Germany and Brisbane Australia. Along with other manufacturers, JR Boone were invited to tender for the project, JR Boone proposing one of their well-proven horizontal helical blade mixers (HHBM). HHBM mixers are available from as little as a 50L capacity all the way up to 10,000L. For this application, a relatively small 500L unit was recommended. The HHBM mixer has four mixing elements forming an interrupted spiral, with very precisely calculated geometry and a short length compared to its width; that gives the mixer substantial advantages over conventional ribbon or spiral mixers. The slow-moving mixer arms gently lift and fold the blend end-to-end, in an action that is so efficient that ‘trace’ components can be added directly to the mix with no need to pre-mix. JR Boone made a strong commercial case, which was followed up with trials performed at JR Boone’s pilot scale plant at their Congleton factory. As Brian Jones, Tate & Lyle’s Engineering Manager, put it; “I have known JR Boone for many years, and they have proved their ability to support us technically, both here and in our factories overseas. We ran supervised trials, with the mixed products then going through our full QC test procedure, which they passed successfully”. As mentioned above, the factory has very strict requirements for clean-down between mixes. The JR Boone mixer was fitted with two full-width doors to make it easy to clean every inch of the mixer interior, so much so that cleaning only requires around ten minutes. To make it easier and safer, the doors are counterbalanced and fitted with quick-release catches. JR Boone also met the Tate & Lyle safety system requirements with the addition of a captive key system, a system that interlocks the lids of the mixer with the mixer drive, so the mixer can’t start with the lid open. The HHBM is designed to discharge quickly with the two outer spirals sweeping the entire shell with every revolution, so there is only a very minimal amount of material remaining in the mixer after the batch. An added advantage is the ‘U’ shaped mixer trough provides additional mixing capacity than standard omega shell, giving a 600L batch size to accommodate lower density ingredients. The mixer was commissioned in December 2012, and has been in full production since.

Bulk Materials Handling

4 SP

For many industries the introduction of new materials into processes can bring challenges that not only relate to handling properties, but in some cases are linked to levels of fugitive particle emission during handling operations (i.e. dustiness). Handling a new material without having characterised its propensity to release fines in to the atmosphere can cause implications linked to serious problems such as incorrect sizing/operation of dust extraction and dust handling equipment through to changes in the ATEX rating for a given plant area or the health of workers exposed to dust. Tests to evaluate the dustiness of bulk materials are relatively straightforward- but often overlooked when planning changes in plant operation. Such tests can be undertaken by The Wolfson Centre for Bulk Solids Handling technology in its extensively equipped laboratories at Chatham, Kent.

The unit was specially designed for the continuous and contact free level control of bulk solids material in silos. The SITRANS LR560 2-wire, 78 GHz FMCW radar level transmitter with its small beam angle of 4° and its very short wavelength allows optimum reflection of the bulk solids material even when confronted with a large material mound and can be used for continuous monitoring of solids in silos up to 100 m. The SITRANS LR560’s “plug and play” performance is ideal for most solids applications, including those with extreme dust and high temperatures to +200°C. The unique design allows safe and simple programming using the graphic display with control keys on the unit or via an infrared handheld programmer or alternatively via Hard-, Profibus PA and Foundation Fieldbus communication. The robust stainless steel construction makes the LR560 extremely suitable for all kinds of industrial applications. The unit operates at a high frequency of 78 GHz thus achieving a very small beam angle which eliminates any signal interference at the flange but allows optimum reflection of the bulk solids material. The flange can be adjusted to ensure a perfect positioning of the LR560, ie the angle of the beam can be set to a specific point, for example the outlet of the silo. The lens antenna is highly resistant to material deposits and offers a self-clean function for extremely sticky solids using an air flush connection. The Local display interface (LDI) allows programming and diagnostics on-site making the installation and operation of the unit as easy as child’s play.

Bulk Bag (F By Keith Simpson - Spiroflow Limited

Because of the industry-wide and worldwide success that Bulk Bags, alternatively known as Flexible Intermediate Bulk Containers (or FIBCs), have enjoyed, there has been a major opportunity for designers and manufacturers in the bulk materials handling industry to produce equipment to fill them. Every manufacturer promotes the specific benefits of their Bulk Bag Fillers to win a slice of the market. Accordingly,

Incorrectly filled bulk bags are at best unpleasing to the eye. A point not to be missed by marketeers who would not want their products delivered to customers in bags that resemble ‘Nora Batty’s Stockings’! At worst, incorrectly filled bulk bags are dangerous. Typically, most bulk bags will contain around 1,000kg of material and a bag that falls over could potentially kill someone especially if it is stacked on top of another or it falls from high up in a racking system. Upright and stable bags are essential if the bags are to be stacked, transported by road or loaded into shipping containers. Using today’s Bulk Bag Fillers, perfectly upright and stable bulk bags can usually be filled to the required volume or weight in less than one minute. That’s also about the time it takes to rig a new bag into position and to remove a filled bag at the end of the cycle. This typically equates to a filling rate of around 20 bags an hour. Continuing the ‘health and safety’ theme: this should all happen dust-free and without spillage. Filling machines are available that can achieve filling rates of up to a hundred 1,000 kg bags an hour and more but, they are very dependent upon so many variables that, in most cases, 50 to 60 bags an hour is more realistic. When selecting a Bulk Bag Filler, the number of bags to be filled an hour is the starting point.

it is essential that those suppliers chosen to submit offers can offer references or demonstrate the

For customers wanting ‘Weights and Measures’ (OIML) approval, reputable suppliers of Bulk Bag Fillers will offer an automatic ‘gain-in-weight’ weighing system probably with programmable one-touch controls. Using such, the operator can control Bulk Bag Filling operations, accurate to +/- 1%, as well as controlling the upstream material feed devices too. The Bulk Bag Filler feed system, whether a conveyor or storage silo above, will be instrumental in enabling the Filler to achieve the bag filling rate required. So, it is best to work with a supplier who can handle those aspects of the system too - and, including all the controls!

veracity of their claims. Any supplier worth his salt will have a Test Centre for the purposes of the latter.

Next is to know whether the bags are to be filled by weight or by volume. Sometimes the decision is easy! For example, if the end product is to be sold by weight then the Bulk Bag Filler will need ‘Weights and Measures’ (OIML) approval. However, there are some consumer and industrial products that are sold by volume such as soil, soil improvers and packaging materials. Other times, it may be necessary for production control to know what is in bulk bags within the factory. Bulk bags are often used to store and/or move intermediate materials in/around the factory between production processes. If such material is to be measured subsequently by way of some other means (such as a receiving hopper on

8 SP

load cells, a metering feeder or a container on a weigh scale) then knowing the weight of the contents in bulk bags used for this purpose may not be relevant. That is, unless it is important for the accountants to know for their monthly reports/annual stock-takes. In which case knowing their contents by weight could be crucial. However, knowing the weight for production or inventory purposes usually means that ‘Weights and Measures’ approval is not required for any Bulk Bag Filler used to fill such bags.

The majority of users will want filled bags mounted on pallets pallet and to remove them by forklift truck. However, there are still some of the heavier industries that prefer to shift bags via their loops. Accordingly, bag removal by pallet or by their loops is another deciding factor in the type of Bulk Bag Filler required. Given today’s robotics, it is now possible to have a fully automated Bulk Bag Filling System. Hitherto, most automated systems have, in truth, only been semi-automatic - still requ-

FIBC) Filling iring the bulk bag to be rigged onto the Bulk Bag Filler manually. Now robots can be used to achieve this too - meaning the whole process from placing a pallet, to rigging the bag, filling the bag to removing the filled bag can be completely automated. Clearly, such automation comes at a price which can usually only be justified in the highest of volume packing applications that operate 24/7. Some of the key elements to consider for Bulk Bag Fillers, whether manually or automatically operated, include: Bag inflation device: inflates the bulk bag (and its liner - if it’s a lined bag) with ambient air and creates slight positive pressure to remove wrinkles and properly form the bag. This assures maximum material capacity and removes folds and creases that could cause problems on discharge. This facility also enables the bag to be inflated with nitrogen or other inert gases when packing materials that oxidise during storage.

detachment of the bulk bag loops to/from the Bulk Bag Filler. This operation is especially beneficial when using a powered roller conveyor as it ensures the bag loops are released before the roller conveyor operates. Movable Filling Head: bringing the filling head to the front of the filler is another aid for easier, safer and faster bag hanging which reduces operator fatigue and eliminates the need for the operator to step onto the filler - which must be avoided at all costs with a roller conveyor base. Roller Bed: the roller bed system, either manual or powered, enables filled bags to be removed from the filler onto a queuing conveyor and an empty bag to be rigged even went a forklift truck is not immediately available making for increased productivity. Electric or pneumatic vibrators: during the filling process, vibrators improve material densification in the Bulk Bag. This increases productivity, maximises the use of space and ensures that filled bags are safe for further handling, storage or transportation and that they are aesthetically pleasing too. ‘Rise and Fall’ Bulk Bag Fillers Where delicate products are to be filled into bulk bags, some Bulk Bag Filler manufactures such as Spiroflow for example have developed fillers which raise the bottom of the bulk bag close to the filling head and they lower the bag as the bag fills. This has proven to be a very successful way of eliminating the damage that can be caused by delicate products dropping great heights.

Ten Top Tips for Bulk Bag Fillers: 1. Match Bulk Bag and Filling Equipment There’s no such thing as a ‘standard’ bulk bag. Bulk bags should be designed specifically to meet your requirements just like the bulk bag filling system. If they are not customised to work together, you’re not maximizing productivity, profit and potentially safety. Bulk bag filling requires systems thinking and customisation to optimize results.

Filling Head with inflatable mechanical seal: this option speeds up bag rigging and ensures a dust tight seal between the Bulk Bag Filler and the bulk bag for hygienic, dust-free operation. A properly designed filling head will also facilitate escape of the displaced air/gas as the bag is filled. Vented air from a product containing dust must be filtered through an appropriate dust extraction system. This is usually the factory’s central system but, where such is not available, most Bulk Bag Filler suppliers can offer integral filtration systems. Powered Height Adjustment: this option enables the operator to quickly adjust the filling head height between filling cycles to accommodate differing size bulk bags. Rear Bag Loops that move forward: for easier bag hanging. Automatic opening of bag hooks: this simultaneously opens/closes all bag hooks to allow for faster attachment/

2. Improve Bulk Bag Stability A recent survey proved that almost 50% of bulk bag filling operations report problems with bulk bags slumping or falling over. This is a safety hazard and compromises productivity and profitability. It also causes inefficient use of warehouse space. Plus, better-densified product requires a shorter bag for a given weight thereby reducing packaging costs. Significant improvements can be achieved by solving densification problems. 3. Optimise Upstream Equipment If the upstream process and related equipment providing product to the bulk bag filler is not optimised you can be suffering from inconsistent weighing, low productivity and anaemic profitability. A customised approach must be taken to integrating bulk bag filling with your production processes to ensure maximum productivity and profitability. 4. Improve Weighing Accuracy If you sell your product by weight and each bulk bag is overfilled by more than 0.5 - 1kg, you are giving away product for free. A bulk bag filling system that weighs precisely and consistently will instantly generate incremental revenue and profit.

SOLIDS HANDLING AND PROCESSING

5. Automate Typically, 1,000kg bulk bags can be filled on a single station machine at rates of 20 - 25 bags per hour with consistent weighing accuracy of ± 0.5 - 1kg and even up to 50 to 60+ bags per hour if pre-weighing is used on a triple station filler. Significant productivity increases can be achieved by automating your bulk bagging operation while improving bag stability and weighing accuracy. 6. Improve Warehouse Utilization 70% of those surveyed indicated that stacking bulk bags was important to them. Can you stack your filled bulk bags 2 or 3 high? If not, you may be passing up an opportunity to significantly increase your warehouse utilisation... and your customer’s. 7. Increase Filling Operation Productivity Is bulk bag filling a bottleneck? Do you have to increase production and your filler can’t keep up? Do you have to manually top-up each bag to its target weight? Could you generate more profit if you could fill bulk bags faster? Does your filling system require more than one operator? Poor productivity is a critical concern of unsuccessful bulk bag filling operations and a key area for improvement. 8. Reduce Packaging Cost Do your filled bulk bags have empty space at the top when you fill them or after they sit in the warehouse? Do your bulk bags have internal baffles to try and improve their stability? If so, you are paying too much for your bulk bags and the combination of the right equipment, application engineering and bulk bag design can solve your problem. 9. Improve Application Engineering Does your bulk bag filling system do what you need? Has it ever? If not, your bagging operation is likely unproductive, less profitable than it could be and possibly even a safety hazard. A customized Optimization Analysis can determine how you can make overall improvements to your bulk bag handling operation. 10. Improve Ergonomics Do your operators struggle with your filling equipment? Do they have to walk into the machine to rig a bag or walk on roller conveyors to attach the bag lifting loops? Does your bulk bag filling equipment require too long a reach to attach the fill spout? Bad ergonomics pose a safety concern and if the filling equipment isn’t easy to use your operators will be unmotivated and unproductive.

New Sieve Technology provides faster Product Changeover at Deloro Stellite Plant Switch to modern sieves cuts product changeover downtime by 300% and achieves ROI in months at coatings operation in Indiana In the quest for greater margins, no processor can afford excess downtime at product changeovers. Nor can they afford excess labor to clean and maintain cumbersome, outdated machines. Yet to avoid cross contamination, especially in bulk powder applications, no corners can be skipped. That’s why streamlining the production process from input to final product screening can be critical. When a coatings processor avoided a production bottleneck by upgrading to a new sieve technology, it saw product changeover accelerate, with rapid payback adding to the bottom line. “We cut downtime from product changeover in third and enhanced product quality by switching to the Russell Finex Compact Sieves,” says Bob Minton, maintenance manager at Deloro Stellite’s coatings operations in Goshen, Indiana. “By expediting cleaning, preventing cross contamination and aiding product quality, we achieved ROI on the Compact Sieves in a few months.”

A Need for Speed Deloro Stellite is a global provider of solutions to industrial wear problems, where heat, corrosion and abrasion can limit component life. It produces proprietary metal alloys from cobalt and nickel, which have metallurgical and physical properties suited to industrial wear challenges. At its coatings operations, sieving was a critical process since the size of powdered metals controls its flowability into customers’ weld points in a range of applications. To streamline production and enhance quality, the company planned to add a new sieving process for all initial powder inputs and final powder products at its Goshen, Indiana plant. While the company used traditional sieves for lower volume powder classifying, Minton felt traditional sieves were too slow and complex for Deloro Stellite’s current needs. “With 5,000 product variations, we’d have to take apart each sieve, clean it and put it back together 10 to 12 times a day,” explains Minton. “We needed a sieving technology that was easier to use than the same old type that’s been on the market for 40 years.” The traditional sieves were cumbersome to work on, take apart, clean and put back together. And if the seals weren’t aligned properly, they could leak, potentially ruining a product batch. “Band clamps wore out, bent, broke or cracked, and the seal had to line up all the way around the flange,” says Minton. “It took two people to work the seal around large diameter units, with no alignment pins or guides.” Fine powder sometimes worked its way into the clamp bolt threads on these traditional sieves too. When this happened, the sieve operators would call maintenance to have the bolt cut off and replaced with a new one. Maintenance was also called whenever sieve vibration adjustments were needed. All this added to production downtime.

At a bulk powder processing show, a traditional sieve supplier promised to show him an assembly “shortcut” but was unable to put the unit back together. Minton decided he’d had enough of traditional sieves, so began a search for low maintenance units in an effort to streamline the production process and simultaneously reduce man-hours.

Speed Delivered In search of a solution, Minton turned to a state-of-the-art Compact Sieve” from Russell Finex. The unit’s design and ease of use impressed Minton, who felt it would expedite product changeover and improve bulk powder processing. A trial proved him right, and now there are four Compact Sieves at the Goshen plant. “One operator can take apart and put together a Compact Sieve in less than a minute with no tools,” says Minton. “Just undo four latches by hand, lift the top off, and then lift the screen out. To assemble it, reverse the process. It seals perfectly. Because the screen drops into a recess, there’s no chance of misalignment; and cleaning is easy with a vacuum line.” “Everything’s right there, easily accessible,” says Minton. “Pop a cap off the end of the motor and there’s your vibration adjustments. It’s so easy to do adjustments that one of our junior process engineers re-aligned it. We showed him once, and he was comfortable enough to make the adjustments himself.” Minton estimates the new sieve technology saves about an hour a day in production downtime, compared to the cumbersome product changeover process required by traditional sieves. Product output and quality are also improved by the new Russell sieves. Traditional designs incorporate a spring-mounted base and a custom motor with a pair of eccentric weights at the end of the motor shaft. However, this design lacks accuracy in controlling the force of vibration imparted to the mesh screen, and is typically limited to a speed of 1200 rpm. In contrast, the Compact Sieves” from Russell Finex omit the need for springs and instead uses a patented rubber suspension system. Combining this with its high speed 1800 rpm vibratory motor and easily adjustable weight system allows much higher forces to be transferred through the mesh screen itself. This creates a more finely-tuned and vigorous action, significantly raising sieving efficiency. “The adjustable weight system makes it easy to set the machines up,” says Minton. “It helps us get the right time on the screens to get every bit of powder possible, while minimizing product loss to oversize.”

The design of these sieves can go a step further to increase throughput by using the Russell Vibrasonic” deblinding system in conjunction with the screen. By energizing the wires of the screen mesh with an ultrasonic vibration, the friction between the product and the screen is effectively removed. In the case of the Russell Finex machines, mesh “blinding” is eliminated, helping to move material through the screens faster. Since the Compact Sieves are crevice-free and entirely constructed from polished stainless steel including their stands, all surfaces are easily cleanable. “The Compact Sieves make it easy for our operators to quickly and cleanly complete product changeovers without tools,” says Minton. “They help with output, product purity, and product loss. Saving even one product batch from possible cross contamination could pay for the cost of the sieves.” “With the new sieves, our customers get a better quality product and better deliverability in the long run,” concludes Minton.

Low Pressure Phase Convey Written by Schenck Process UK The pet food industry has long searched for a method to convey finished product from process to storage and packaging in a reliable, inexpensive, maintenance-free system that yields little or no breakage. In the past the industry has relied heavily on mechanical methods. There are many advantages and disadvantages to conveying with mechanical and pneumatic systems. Mechanical Handling is fairly inexpensive if conveying a short distance or transferring between process operations. However, the equipment - bucket elevators, conveyor belts, chain conveyors, and screw conveyors - have many moving parts. In addition to being high maintenance, they also provoke serious cross-contamination concerns, produce high amounts of breakage and occupy large amounts of space within the plant. In addition, the ability to change from horizontal to vertical with a mechanical system poses design layout problems. Pneumatic conveying methods are fairly well known but typically misunderstood and disregarded due to the perceptions of breakage. Advances in system design and control makes low pressure continuous dense phase (LPCDP) a simple way to pneumatically convey dry pet foods with minimum product breakage and cleanliness unmatched by mechanical conveying methods.

Pneumatic system options

Pneumatic systems include both dilute phase and dense phase systems. Dilute phase systems convey at air velocities high enough to keep the particles suspended in the air stream. The high velocities required to convey in this manner often generate high amounts of breakage. Dense phase systems convey particles below the minimum velocity for suspension flow characteristically in a slug or moving bed. Low velocities are gentler on all kinds of product and therefore produce less overall breakage. The air requirements for dense phase systems are significantly less than dilute phase. Dense phase systems can be further categorized into batch dense phase and continuous dense phase. Batch dense phase is the classic method of conveying at low velocity. The material is dropped into a pressure vessel and then the material is forced into the convey line using relatively small volumes of compressed air. Although this method can result in reduced product breakage, it is a batch process, it can have greater headroom requirements and is not so flexible for varying rates and products. Continuous dense phase employs a precision machined airlock to continuously introduce material into the convey line, requires a relatively low amount of headroom and is still able to gently convey at low velocities. A disadvantage of using an airlock is that leakage of air through the airlock can generally result in unstable systems. However, stable dense phase systems are attainable when using an airlock, if the leakage air is accounted for in the air supply controls.

12 SP

SOLIDS HANDLING AND PROCESSING

e Continuous Dense ying of Dry Pet Foods Slug formation in a dense phase system is the key to minimizing product degradation. Slugs of material that gently form and move through the system are stable and are less likely to break products such as kibble. A system that constantly forms and breaks plugs in a convey line is said to lack stability and can damage the product as much or more than mechanical methods.

Maintaining consistent product feed Stable dense phase systems are a result of consistent product and air supplies that are fed to the convey line. Consistent product feed is managed by way of an airlock rotating at a constant speed. Maintaining consistent convey air supply (QS) is difficult because the leakage through the airlock (QL) is constantly changing as a result of the pressure below the airlock. For a constant QS, where QL is constantly changing, then the convey air (QC) will be constantly changing as well. However, a system that varies QS according to the pressure below the airlock to account for the varying QL can deliver a constant supply of air to the convey line. (See Figure 1) This can however be accomplished by linking pressure transducers at the material feeder (airlock)to a variable air flow valve downstream of the blower unit. The air flow valve â&#x20AC;&#x153;Macturiâ&#x20AC;? automatically adjusts to pressure fluctuations at the Figure 1 feed point, and therefore instantaneously expands and retracts the supply air to account for fluctuating airlock leakage. Consistent material and air feed at proper material-to-air ratios produce proper slugging and therefore a stable dense phase conveying system. The characteristic of a LPCDP system that designates it as low pressure is the friction associated with moving a slug of material through the system. By minimizing the friction generated by the slug, the differential pressure needed to move the slug down the convey line is minimized. This in turn ensures a minimal convey pressure considering the convey pressure is essentially the sum of the individual differential pressures of the slugs. Much of the friction minimization is material intensive. Products such as pet foods have porous surfaces and low densities. Together these characteristics indicate the product will naturally generate very little friction. Further measures are taken to reduce the friction in these systems including: polished stainless steel piping, seamless pipe joints and long radius elbows.

Receiving area for raw materials A concern when debating the use of a low pressure dense phase system can be the compressed air source. High pressure plant air is generally required as the motive force, as opposed to a Roots type blower due to the pressures involved. Low Pressure Continuous Dense Phase (LPCDP), however, characteristically conveys under 1 barg. The air source is then optional depending on the individual plant needs. A plant that is running low on

SOLIDS HANDLING AND PROCESSING

high pressure air can opt to employ a Roots type blower. Conversely, a plant that has an ample supply of high pressure compressed air can reduce their capital expense by using their existing air so long as the compressed air quality is acceptable. With many of the misconceptions and mysteries of LPCDP addressed, one can then look at the pure advantages this system possesses as compared to its mechanical counterparts. With many pet food plants functioning more as a human food plant, housekeeping becomes a significant issue. While most mechanical methods are hardly dust free and often uncovered, pneumatic lines are completely enclosed and filter out dust at the destination. This feature results in great leaps in cleanliness and sanitation. Maintenance is a huge issue when comparing pneumatic systems to mechanical methods. Very few moving parts means less parts that can wear, break or come off track. Rather than thousands of bearings, rollers and belts, the moving parts on an LPCDP system include only an airlock, variable orifice and an automatic valve. Properly designed and operated systems can eliminate plugging issues. Changing product in the convey line is accomplished by a simple purge with nearly zero cross contamination. Thousands of man-hours can be saved on this point alone.

Reduced pet food breakage LPCDP systems convey pet food products gently and with consistently less breakage or fines generation than either dilute phase systems or mechanical methods. The reduced amount of product degradation that occurs in the LPCDP system benefits the overall process. Reduced amounts of fines that are screened off the product equate to less reworked material. Less reworked material equates to a more efficient process and higher quality product. Likewise, packaging lines also benefit when less fines are generated, because fewer fines are actually packaged. This is perceived as the most substantial advantage. The final step to assessing the viability of incorporating an LPCDP system is analysing the ease of system integration. The inlet of the system requires only a minimal headroom. This is often ideal for feeding off other pieces of equipment such as dryers, or conveying from storage such as bins or silos. The convey line can then run to any destination desired, through nearly any path required. Pneumatic convey lines run horizontally, vertically, through walls, through floors and across ceilings as needed. Prototypical PLC configurations and equipment are used to control LPCDP systems. Thus, controls are easily integrated to work with other processes and the states and alarms of other systems. Lastly, the capacity and flexibility of LPCDP systems are superior to other convey methods. Altering rates is often as simple as altering the speed of the airlock and changing the air supply to match. Conveying a product with very different characteristics is usually as simple as changing a few constants in the PLC configuration. This can be done automatically for systems that routinely convey various products through the same convey line. All things considered, LPCDP is more versatile, gentler to the product and requires less maintenance than dilute phase conveying or any of the several mechanical conveying methods. With the recent swing the pet food industry is making toward improving efficiency, cleanliness and sanitation of their plants, LPCDP is a sound investment. The Schenck Process E-finity LPCDP system has been installed in many Pet Food factories providing the full range of benefits outlined in this report.

System Selection - can a Level Playing Field Exist? Introduction When purchasing plant or equipment the desire to get the best value is often driven by an over emphasis on the price quoted in tender documents and the relationship between this and the (invariably) strongly constrained capital budget used to deliver the project. This article will consider the implications of ‘value engineering’ on system (or equipment) design and functionality. The main issues The main problem that can present itself to project managers / engineers is often related to the meaningful evaluation of tender responses. It is by no means unknown for five equipment suppliers to submit significantly different designs - all of which would have been based on a common supplied specification. This can present major issues for the evaluation of the systems. Often the fact that each supplier will have provided a process guarantee will be perceived as a minimisation of risk by the end user and can in some cases drive the final selection down the route of who can provided the combination of low cost and quickest delivery time on site. In principle, this premise for selection does not seem unreasonable and certainly falls in with project management practices across many sectors of industry. However, what appears to a rational approach to selection can ‘back fire’ badly if the technical risk of what is being offered is not correctly assessed or even identified in the first instance. A failure to fully address technical risk can lead to the installation of inappropriate equipment, extended commissioning and possibly a long term failure to attain projected production rates.

Where can it all go wrong? One of the main reasons why such variations in tender responses can be generated is often due to vaguely written specifications that lack sufficient technical rigour upon which to base a fully informed design. A balance should be made between allowing sufficient latitude for suppliers to implement their specialist knowledge with the specification framework and ensuring the inclusion of key technical points to steer their collective responses in a concerted way. This may sound like common sense for the initiation of a tendering process for any industry - but it is all the more critical for the process industries that work with powder or granular materials. The storage and handling characteristics of bulk materials make them very sensitive to the finer points equipment or system designs - which is one reason why so many plants experience problems with processing these types of material.

An example of the dilemma that can develop relates to the seemingly simple task of procuring a storage silo. Often the main guidance in the specification will focus upon spatial constraints and vessel volume requirements. Reference to the materials to be handled is likely to range from sparse (i.e. its name) to un-useful from a design perspective (angle of repose, tapped bulk density, median particle size). Consideration as to how the material is likely to behave when passed through the equipment is usually limited to “....discharge reliably...” - again, not very helpful in a practical sense. The questions that should be asked at the time of writing the specification ought to consider: does the material ‘cake’ if stored for too long, is it prone to segregation, does it gain strength with time such that flow initiation may be an issue, how accurate will the feeder discharge requirements be (the vessel must be designed with these in mind if high accuracy is required). Too often these questions are not posed or insufficient information is available to form a meaningful view.This leads to ambiguity in the requirements the most fundamental of which is whether core flow or mass flow is 1) Arching

a process requirement. These are basic items which are often omitted. Whether a supplier will seek clarification of what is actually needed is unlikely if the specification is seen as being a definitive document. In such instances a failure to make clear reference to how the process is intended to work (or how the equipment is intended to integrate with existing plant) can be taken as an indication that no special considerations for design exist. This, in effect, can give suppliers a relatively free hand to fall back on previous experience and standard equipment ranges to evolve their response. Thus a specification can generate quite diverse options between suppliers.

2) Rat-holing

Failure to apply a knowledge of powder flow behaviour can lead to equipment problems; 1) Arching 2) Rat-holing 3) Hammer-rash

3) Hammer-rash Perhaps one of the more potentially damaging aspects of the progress towards a final installation (following initial acceptance) is the implementation of ‘value engineering’ to a design that is quite likely already in quite a (technically) stripped down form in order to bring the costs down to a level that make it competitive. In such instances it is not unknown for aspects of equipment considered to extraneous to the main function to removed altogether. Again, commercial pressures can be seen to increase the risk to the efficiency of the final plant, but the real danger lies in the failure to correctly identify the risks that are being increased. It is unfortunate that the widespread lack of reference materials combined with minimal opportunities for engineers to familiarise themselves with the technology of powder/granular materials characteristics and handling, makes this type of exercise potentially a high risk activity in its own right!

Conclusion In answer to the consideration as to whether an ‘even playing field’ can exist to assess tenders? - possibly not as long as the technical aspects of tender documents are subsumed purely by commercial consideration. If suppliers are presented with technically sound and rigorous specifications that fully consider the requirements of the bulk materials being handled, a more meaningful comparison has a more chance of occurring. However, the underlying message for end users and suppliers is that an awareness of bulk solids handling and the nuances of the products to be processed must form one of the underpinning elements in any of the procurement steps discussed in this (brief) article.
