ABB’S UK ENGINEERING CENTRE DOUBLES IN SIZE TO MEET RISING DEMAND ABB has doubled the size of its UK Engineering Centre to tackle demand for servicing variable speed drives (VSDs), developing specialist test rigs (STRs) and customer training. Floorspace at the site in Coalville, Leicestershire, is increased from 830 m2 to 1789 m2. The site houses the latest ABB-certified workshop – one of 17 throughout the world - offering repairs and upgrades to low voltage AC and DC drives and medium voltage AC drives. The facility upgrades third party medium voltage drives, as well as those of ABB. “Many operators across multiple industries are finding that their variable speed drives are no longer supported by the original vendor. ABB can integrate new variable speed drives and control platforms to these systems, ensuring operators can continue to benefit from their substantial investment in equipment,” says Stuart Melling, Business Unit Manager, ABB Drives UK. The new facility houses ABB’s STR business, for which a new class of test rig for electric vehicles, incorporating battery simulators and electric chargers, is being developed. The location boasts the largest VSD training school in the UK, offering customers access to certified courses covering low-, medium- and high-power drives. Coalville sees the introduction of the ABB AbilityTM Remote Support Centre. This enables global customers to maximise uptime and optimise processes by having round-the-clock access to drive and automation experts who use cloud-based technologies for preventive and predictive maintenance. Apprentice Lucy Tudor cuts the ribbon at the opening of ABB’s UK Engineering Centre in Coalville
“Being in the heart of Leicestershire with good access to the M1, M42 and M6 motorways, the Coalville facility is a great location for everything from spares distribution to easy access for customer training,” says Paul T.

CASE STUDIES: HOW TWO PETROCHEMICAL PLANTS IMPROVED LEVEL AND FLOW MEASUREMENT Managing petrochemical plants requires monitoring a variety of complex processes. Preventing accidents is a key concern, as well as ensuring that no product is lost and that the highest quality is maintained. The level and flow instrumentation used to monitor these processes often makes a significant impact on plant efficiency and safety. Magnetrol® produces a wide range of level and flow instrumentation that can be used in petrochemical plants. This blog post shares the stories of two plants that improved their petrochemical production and better monitored their facilities by using MAGNETROL products.
PROBLEM: NOT ALL GUIDED WAVE RADAR IS CREATED EQUAL
MOTOR AND DRIVES FROM ABB BRING FARM HISTORY TO LIFE FOR STATELY HOME VISITORS State-of-the-art drives and motor power 200 year old farm machinery used to explain innovation in food production over the centuries. A farm in Cheshire, UK, is bringing 200 years of agricultural history to life for visitors using a 21st century motor and energyefficient variable speed drives (VSDs). ABB and its authorised value provider, Central Electrical, supported the Tatton Hall estate’s £1.3 million Field to Fork project by supplying an ABB motor and eight VSDs to run original farm machinery. They also overhauled and rewound existing motors from the 1930s, 1940s and 1950s, while providing motor and drive selection, installation and commissioning services. Tatton Hall is an historic country estate, incorporating gardens, woodland and a working farm. A major part of Tatton Hall’s Field to Fork project is the restoration of the farm’s Victorian mill, which produced feed for the farm’s livestock using machinery such as grinders and crushers. Previously run by water power, then steam and, finally, electricity, the grinders and crushers are now powered by eight ABB general purpose drives, rated from 2 kilowatt (kW) to 18.5 kW. The VSDs provide a ‘soft start’ which, together with running the mill machinery at lower speed, reduces excessive wear and extends the operating life of the machines. The farm’s miller can use a mobile phone or iPad, connected remotely to the VSDs, to control the grinder and crusher motors to enable them to talk through the demonstrations at different speeds. On the ground floor of the feed mill, a VSD is used to operate a hammer mill which crushes barley, wheat and oats into pig meal. On the first floor is a crushing and grinding machine for preparing cattle feed. Other VSDs run a winnower, a mixer and a sack hoist used to take heavy sacks up to the first floor storage room. An ABB industrial drive is used to run a refurbished steam engine, which originally powered the other farm machines. The VSD solved a problem of excessive vibration during engine startup. This vibration threatened to damage the mill’s foundations. The VSD controls the engine’s motor and gear box to give a soft start, avoiding the vibrations.

it was the only device tested that could produce reliable measurements with a completely dry probe, a probe having only one of the two process media present, and under varying interface conditions.
PROBLEM: MEASURING BLANKETING GAS TO REDUCE COST An oil & gas and petrochemical company in China required nitrogen tank blanketing for their flammable liquid containment. Monitoring the nitrogen was essential to account for leakage and verify flow going into the vapor space of the tanks. Due to the number of tanks, the gas flow was monitored to find the right balance between the necessary nitrogen usage and potential cost savings.
SOLUTION: MAGNETROL recommended its Thermatel® TA2 thermal mass flow meters to monitor the nitrogen for tank blanketing. The meters came fully calibrated and configured so the company could simply install them and power up. THERMATEL TA2 flow meters are very effective in extreme low gas pressures, such as in tank blanketing applications.
One of the world’s largest oil & gas and petrochemical companies was having problems with multiphase applications involving hydrocarbon level with water bottoms and gas vapor space. Guided wave radar (GWR) technology was introduced to monitor these applications. However, the GWR devices selected did not produce a reliable signal throughout the measurement range, and the dynamics of the interface made it difficult to distinguish between the upper level and the water below. There was a threat of loss of primary containment (LOPC) due to these measurement errors.
SOLUTION: MAGNETROL pioneered GWR technology for level measurement and its latest device, the Eclipse® Model 706, is considered the highest performing GWR level transmitter on the market. The ECLIPSE Model 706 was tested side-by-side with multiple GWR competitors for both top level and interface measurements and it was proven to be best-in-class.
RESULT: Total cost of ownership was reduced with calibration verification procedures that could be performed in the field. Since calibrations can cost tens of thousands of dollars and cause process downtime or loss of measurement, this saved money and increased efficiency for the company.
RESULT:
More Information
The ECLIPSE 706 tracked level up to the device’s flanged process connection, above 100% level, with no dead zones or blind spots at the top of the probe. It prevented LOPC by tracking the top hydrocarbon level through the vapor space and also measured the interface (water bottom) due to the superior signal strength. In summary,
MAGNETROL offers numerous level and flow solutions for ethylene applications, including petrochemical production. To learn more about the products we offer and how they can help increase the efficiency and safety of petrochemical plants, download our ethylene brochure.
BREDEL PUMPS SAVE SLOVENIAN WASTE WATER TREATMENT PLANT TIME AND MONEY s "REDEL Pumps replace troublesome progressive cavity (PC) pumps s 2EDUCTION IN MAINTENANCE ALLOWS RETURN ON investment in just 12 months. s .2 %NDURANCE HOSEs provide impressive lifetime handling abrasive sludge Celje is the third largest city in Slovenia and sits at the junction of the Savinja, Hudinja, Ložnica, and Voglajna rivers in the lower Savinja Valley. Serving a population of 85,000 people, the city’s waste water treatment plant (WWTP) used two progressive cavity (PC) pumps to feed a centrifuge with settled sludge. The abrasive nature of the sludge meant that the PC pumps suffered stator and rotor wear, leading to a drop in flow rates, as well as the need for regular maintenance downtime. Maintenance often took several hours to complete and required expensive spare parts. To reduce costs in the Celje WWTP sludge handling duty, Watson-Marlow Fluid Technology Group recommended two Bredel 65 peristaltic hose pumps, fitted with abrasiveresistant NR Endurance hoses, as replacements for the troublesome PC pumps. Bredel hose pumps have no seals, diaphragms, glands, immersed rotors, stators or pistons to leak, clog or wear. And, unlike other pump types, viscous, grit-filled sludge
does not affect their performance. The hose is the pump; a single component change is usually the only maintenance required, with time to change a hose measured in minutes rather than hours. Bredel’s NR Endurance hoses are providing an impressive lifetime of between 10 and 12 months, significantly reducing the need for maintenance downtime, enabling the waste water treatment plant to achieve a return on investment in just 12 months.

HEALTH & SAFETY
REMOVAL OF MICROPLASTICS FROM WATER STREAMS USING MEMBRANE TECHNOLOGY
Martindale Electric – UK market leaders in safe isolation – is pleased to announce the arrival of its latest CABLOK series, which provides installers and maintenance teams with a simple and reliable solution for locking off multiple breakers, switches and valves, to prevent the re-energising of circuits and systems during maintenance, as part of a safe isolation procedure.
The removal of microplastics from drinking, process or wastewater streams is a major step towards the reduction of microplastic pollution found in the environment. The use of plastic microbeads in cosmetics and personal care products has already been banned in the UK and many other countries. However microplastic pollution is still being generated by the waste plastics already in the environment which are aging and self-abrading on a very wide scale. As a result, most water sources now contain background but rising levels of microplastic contamination, which can ultimately feed back into in the human food chain. Crossflow Membrane Technology (CMT), renowned for its success in the removal of bacteria, pesticides, suspended solids and colour from wastewater, is now a practical solution in the fight against the microplastic pollution found in most wastewater streams. CMT works as a physical barrier against microplastics where the particulates cannot pass through the membrane on the basis of particle size, allowing only crystal clear commercially sterile, particle free water to be discharged. All the microplastic particulates and other separated impurities are safely retained in a low volume controllable form ready for further treatment. Axium Process specialises in Crossflow Membrane Technology and is working with companies wishing to evaluate the benefits of

Digitalisation is the best way to get a taste of the future
By Filip Schiettecat, Senior Director Industry Management, Siemens PLM Software BY DEFINITION, THE FOOD AND BEVERAGE INDUSTRY IS FAST MOVING AND ALWAYS CHANGING; MILK GOES OFF, BREAD GETS EATEN, AND WE WANT TO EAT MORE SALADS IN THE SUMMER. But the combination of changing consumer demand, increasing regulation, complex supply chains for global sourcing and distribution, and competition from agile new competitors means food and beverage companies have to move faster than ever. And they have to do all that while still keeping quality high and appealing to customers who want products that suit them perfectly – whether that means gluten free, low sugar or even custom flavours. Market predictions say there will be more changes in consumer packaged goods in the next five years than there have been in the last fifty. The only way to keep up is digitalization, which is your best opportunity to reduce time to market, improve efficiency and get ready for the future of manufacturing. It’s very common for food and beverage companies to be fragmented; that’s not just different departments like product development and marketing, but different product lines will come from different teams who just aren’t connected. If you make both pasta and cheese, they might end up in the same shopping basket and even on the same plate, but if there’s poor communications between the teams behind them you miss out on opportunities to save time and money by sharing information about suppliers and ingredients, process technologies and the shopper who’s buying both of them. Even within the same product line, entering the same information about ingredients over and over again at different stages of the process means the chance to make a mistake every time that information gets recorded. Using a digital thread means information only needs to be entered once and can then be re-used at every stage of the process: from creating the first model of the product that allows you to calculate its nutritional profile, through finalising the product formula and recipe in the lab, to monitoring the whole manufacturing chain and tracking those ingredients from multiple suppliers all the way to your final customer. This kind of traceability is key for keeping products consistent and delivering high quality, as well as being able to comply with regulations and keep recalls as limited and transparent as possible. Managing all of this digitally also saves you money and time. Driven by fashion, social media, broadening interest in different cuisines and increasing concerns about health and allergies, consumer habits and tastes are changing faster than ever. Shoppers want new and interesting products; they want high quality and low prices on everyday items. They want detailed information about what they’re buying, from where and how it was grown to nutritional and allergen information. They want to know if a fruit snack is made with whole apples, apple puree or

freeze-dried apple powder. One day a consumer might be looking for products with alternatives to sugar; next week they might be concerned about artificial sweeteners. They want more choice of products, in exactly the right pack size for them. They even want custom products, whether that’s a new flavour of an old favourite, a lowcalorie or allergen free option or personalised packaging. Mixing up different soft drink flavours in a phone app, 3D printed chocolate souvenirs from your holiday or a pack of cookies with your name and design printed on them might be novelties today, but they’re a sign of the trend to more and more differentiation.
At the same time, the price of raw materials is rising, as are the numbers of regional and global regulations. The EU, for example, is currently proposing rules to increase consumer transparency for ingredients like enzymes and flavourings, GMOs, food and feed additives, smoke flavourings and even food contact materials, as well as cracking down on companies who use the same advertising for products made with different ingredients in different countries. Food and beverage companies need to track and label ingredients for an ever-increasing variety of products and recipes, coming from different suppliers and shipping into different markets around the world through multiple supply and distribution chains. Paper-based processes simple can’t handle the scale and complexity. The bigger your product portfolio, the more variance, volume, complexity or different country regulations you deal with, the more digitalization can help. It’s also a key first step to prepare for the future. That future is digital food: not the food pills of science fiction but wine, beer, cheese, meat and vegetables that have been tracked from the field and farm into the factory for consistent quality.
Dairy Digital Factory
MANUFACTURING WILL DETERMINE THE FUTURE To meet those market demands, you need to develop multiple product variations, which may require different production lines – often more products and processes than you can create and test with traditional methods. Again, digitalization is the way to cope. Creating a digital twin for new products and the processes you’ll use to manufacture them lets you design and simulate product performance to make sure every new variant meets compliance regulations and market needs before you even prototype it at lab scale, so you can scale up quickly, manage testing in production to make sure your production matches what was designed, and track which ingredients from which source make it into which product shipped to which customers. A digital twin can reduce how long it takes to get a new product onto the market by up to half.
Using sensors and automation to handle the milk arriving in a dairy and the fermentation of the cheese it’s used to make can cut production time in half and reduce energy costs without compromising quality. Digitizing cellars and fermentation tanks gives brewers better control over temperatures as well as telling them when they can decant a batch of beer and clean the tanks, given them more time to experiment with beer recipes and letting them brew more varieties of beer without needing to buy more equipment. Recording the pesticide levels in the vineyard and sending alerts if the temperature in a fermenting barrel of wine is too high or too low keeps costs down and the quality of the final bottle of wine up. This kind of sophisticated monitoring and automation may be the exception rather than the norm today, but can you count on your competition not making those investments? To benefit from this kind of flexibility, consistent quality and reduced costs for your own processes, and to get your share of market opportunities that 3 billion new customers will generate by 2020, it’s time to start implementing your digitalization strategy now.

PROCESS MEASUREMENT & INSTRUMENTATION
A BRITISH FIRM HAS DEVISED A DEVICE TO SAVE TIME AND MONEY FOR THOUSANDS OF COMPANIES
HIGH-PRESSURE FLOWMETER MEASURES LIQUID REFRIGERANTS
Adding water to powder or granule mixes has long been done using pails or hosepipes. Time consuming, open to accident and operator error, there has never been a viable alternative. Aquameter Ltd looks set to change that. Their micro-controlled Abacus system delivers exact, pre-selected quantities of water from a single pipe -straight into the mixing vessel. This precise metering of the water means the operator can recreate batch consistency each time. Operation is simple - the quantity of water required is programmed in, the RUN button pushed, and the water flows. A solenoid valve located in the water pipe closes the flow at the completion of the cycle - when the pre-set quantity has been reached. The unit is already in use world wide. Derek Baxter, International Projects Director with Filtrona International in Jarrow, says of the system: “We use the unit for metering water into a carbon-powder mix. Were it not for these units we would be using buckets of water, a line of hose, or a constantly changing mark on the tank - not that convenient.� He goes on: “With this thing we just dial new numbers in, and away we go - it’s obviously more accurate; using the meter than relying on staff to put it in by pail. “
Titan Enterprises, a leading manufacturer of specialist flowmeter, reports on the development of a high-pressure turbine meter for measuring the flow of liquid refrigerants.
For further information please contact; John Morton aquameter limited 8 Woodlands Drive HODDESDON EN11 8AZ Tel: 01992 442 861 E-mail: john@aquameter.co.uk Web: www.aquameter.co.uk
In response to their OEM customer’s requirements, Titan Enterprises designed a flowmeterable to deliver reliable, high performance across 6 flow ranges from 0.05 to 15 litres perminute. To ensure the highest degree of inertness to the refrigerant fluids the flowmeterpolymer components were moulded in an FDA approved grade of Polyvinylidene difluoride(PDVF) and mounted in a 316 stainless steel body.
Incorporating steel reinforced polymer components, to give a pressure rating of 40 Bar, the low inertia turbines of the flowmeter have proven ideal for measuring the low viscosities (0.3 to 0.4 entipoises) encountered with volatile refrigerant fluids measured in the liquid form. With careful sensor selection the pressure drop through the flowmeter is low enough to prevent gas break-out and ensure reliable flow measurement from -25°C to +125°C.

HOFFMANN + KRIPPNER LAUNCHES NEW MINIATURE P53 ULTRASONIC SENSOR ‘SMART’ SENSOR PROVIDES CONTINUOUS FEEDBACK & DIAGNOSTICS A smart valve sensor which provides continuous feedback and essential diagnostics to help plant operators ensure optimum process performance has recently been introduced by sensor specialist ifm electronic. The MVQ smart valve sensor provides outstanding, all-round position visibility with bright multi-coloured LED indication helping plant operators to monitor the flow of media from a distance. For example, is the valve open or closed? Is the valve opening fully? Or is it blocked by deposits? Is it closed properly, or is the seal wearing? If used as a standard sensor the MVQ will provide 3 switched signals for the valve position. However, thanks to the integrated IO-Link interface the sensor becomes a realtime diagnostic device providing continuous real-time feedback, as opposed to a simple, less sophisticated valve position sensor.

The fine resolution of just 0.1º provides operators with accurate information on the conditions inside the valve, with adjustable tolerances to allow for different types of media and the age of the valve. In addition, the MVQ can also measure the time taken for the valve to move, alerting operators to the possible need for maintenance. Any end position of the valve and the size of the sensing range can also be set. Also, a third switch point can be selected, for example for 3-way valves or for a diagnostic alarm. This flexible configuration is enabled with the smart valve sensor by the ifm application software LR Device or an inductive ‘teach button’. For more information contact: Jon Morris, ifm electronic ltd, Hampton, Greater London.

FEATURED ARTICLE
By Matthew Crewe, Managing Director of Green’s
Optimising waste heat recovery brings a range of benefits to processing plants says Matthew Crewe, Managing Director of Green’s Given the need to reduce carbon emissions, protect our environment and reduce fossil fuel consumption, waste heat recovery is increasingly important. There are various ways that this can be done depending on the processes that are being undertaken that result in waste heat, the applications that the captured waste heat is going to be used for and the size and location of the plant.
Components ready for assembly
In processing plants, a waste heat recovery system will usually include economiser/s and/or a waste heat boiler. An economiser unit is typically installed on the exhaust system from a steam and hot water boiler to reduce the flue gas temperature and increase the thermal efficiency. This will be formed of an appropriate tube configuration that will be determined by taking into account the type of fuel that is being burnt, the temperatures that are being handled, pressures and the space available. A waste heat boiler recovers heat from hot gas streams, that still have a relatively high energy content which would otherwise go up the chimney and out into the atmosphere. Capturing the exhaust energy from diesel or gas engines by reducing the flue gas temperature from, for example, 400°C to 180°C, allows processing plants to maximise energy usage and increase production efficiency.
FOR A HEAT RECOVERY CAPITAL INVESTMENT PROJECT, PLANT MANAGERS WOULD NEED TO CONSIDER THE FOLLOWING FACTORS FOR THE RETURN OF INVESTMENT (ROI): s !VAILABLE WASTE ENERGY IN THE EXHAUST GAS SYSTEM s -ANUFACTURING AND INSTALLATION COST OF THE HEAT RECOVERY UNIT s 0HYSICAL SPACE AVAILABLE IN THE PLANT FOR THE HEAT RECOVERY unit s %FlCIENCY SAVINGS BASED ON PLANT OPERATIONAL HOURS s &UEL COST SAVINGS FROM INCREASED PLANT EFlCIENCY s 2EDUCING CARBON AND HARMFUL EMISSIONS
COMMON APPLICATIONS FOR REUSING THE WASTE HEAT THAT HAS BEEN RECOVERED : s PRE HEATING COMBUSTION AIR FOR BOILERS OVENS AND FURNACES s PRE HEATING FRESH AIR USED TO VENTILATE THE BUILDING s HOT WATER GENERATION INCLUDING PRE HEATING BOILER FEED WATER s DIRECT STEAM GENERATION FOR PROCESS OR POWER GENERATION s SPACE HEATING s DRYING s OTHER HEATING OR PRE HEATING FOR INDUSTRIAL PROCESSES However, before a waste heat recovery system can be designed for a processing plant to obtain these benefits, managers need to provide the supplier with information that will help to inform an effective system. This includes the type of fuel that will be used and data about the flue gas including flowrate, composition and inlet temperature. It is, of course, essential to know where the system will be located and the space available which will be used to determine the best materials and tube arrangements.

Using this information, the supplier will work on the optimum thermal design which will include outputs such as the best working fluid i.e. water, saturated steam, superheated steam or thermal oil, flowrate, thermal duty, waterside pressure drop, gas side pressure drop, working fluid outlet temperature and operating pressure. All of this information will then be used to formulate pressure part calculations and develop the mechanical and structural design that specifies factors such as the system’s weight, width and length and, in some cases seismic calculations and wind loading calculations. Use of systems in processing plants brings particular challenges for their waste heat recovery systems. For example, if the plant has a dusty atmosphere, this will influence the types of tubes that are used and which fins are employed. Generally, the fins need to have relatively large gaps between them, which is known as a wide pitch specification. They also need to have as high a heat transfer surface as possible making H-finned tubes a frequently specified solution.
The environment in which equipment operates, varying quality of feed water and rigorous operating patterns can result, over time, in reduction in efficiency or even total machine failure. To avoid this, it is vital to commission a proactive inspection service to identify potential problems with waste heat recover equipment so that they can be addressed in order to maintain optimum efficiency and before they become unnecessarily costly or result in avoidable downtime. This will usually include examination of the internal surfaces of the economiser and waste heat boiler during planned outages to ensure fouling and erosion issues are not occurring and online cleaning equipment such as soot blowers, are operating correctly. Typically, a comprehensive report will be submitted to the client after the examination work, stating the condition of the examined surfaces and recording corrective measures needed so that a plan can be put into place that keeps these vital pieces of equipment working efficiently.
Processing plant managers should also ensure that their chosen supplier has the required experience, track record and industry accreditations to be able to design and manufacture a system that meets all regulatory and insurance needs. This can only be achieved by companies that have stringent quality and technical assessment processes in place and is best checked by visiting their facilities to see what they offer first hand. Having invested in a waste heat recovery system with the aim of making energy usage more efficient and reducing costs, it is highly recommended to initiate a planned maintenance programme to ensure that its lifespan is extended as much as possible and that unplanned outages are minimised.

Finding value
in liquid waste streams
Waste is increasingly being viewed as a resource. From well-established practices such as recycling paper and aluminium, to the development of the circular economy, an increasing volume of resources are now being recovered from materials that were previously seen only as inconvenient wastes. Matt Hale, International Sales and Marketing Director at HRS Heat Exchangers, looks at how value can be extracted from liquid waste streams and what to consider when choosing technology to achieve this. WHY RECOVER WASTE? Waste valorisation is the process of recovering value from waste materials, for example through reusing or recycling them, or by composting or anaerobically digesting them and converting them into more useful products such as materials, chemicals, fuels or other sources of energy. In a circular economy, compared to a linear one, the materials within products are reused, turning previously burdensome wastes into valuable resources. The European Union has proposed to double its rate of resource productivity by 2030 and as part of this, adopted a communication, Towards a circular economy: a zero waste programme for Europe, in July 20141 . Like key industrial stakeholders and businesses, it asserts that moving to a circular economy can have a positive effect on economic growth and strengthen the competitiveness of companies, in addition to providing a number of environmental benefits.
EXAMPLES OF RESOURCE RECOVERY While we are still a significant way away from the commercial development of large scale biorefineries which can treat wastewater streams to produce a range of products including biofuels, energy, fertilisers, metals, inert media and a whole range of fine chemicals, parts of this process are already established. The use of anaerobic digestion (AD) to recover energy and create organic biofertiliser (digestate) from food and sewage waste is now widespread, and there are various examples of material recovery from different waste streams at all scales, from early research through to fully commercial recovery units at industrial facilities and water treatment works around the world. Some examples of this type of material recovery include: s 2ECOVERY OF KEY NUTRIENTS SUCH AS PHOSPHOROUS FROM sewage streams for use as agricultural fertilisers. s 4HE POTENTIAL RECOVERY OF BIOPOLYMERS SUCH AS polyhydoxyalkanoates (PHAs) and polyphenols from the wastewater from olive mills.3 s #HEESE WHEY WASTEWATER #77 COMPRISES WASTE streams including whey and wash-out water, and could be treated using various processes to produce a range of products which are useful in food manufacturing and pharmaceuticals, such as whey proteins, peptides, lactose, glucose and other useful chemicals. s 4HE RECOVERY OF SPENT YEAST PRODUCTS FROM VARIOUS processes for use in food production, such as stabilising and pH buffering. Fruit processing is another sector that is ideally placed to capitalise on the potential value of some of its waste products. Citrus peel waste accounts for up to half the total volume of citrus fruit processed globally and contains up to 80 per cent water. It is a potential source of many useful products including dietary fibre, antioxidants, food colorants and flavours, and contains a wide variety of compounds including cellulose, pectin, sugars, hemicelluloses, flavonoids and essential oils such as D- limonene. MOVING TOWARDS ZERO LIQUID DISCHARGE
UNLEASHING THE POTENTIAL FOR LIQUID WASTE STREAMS Wastewater treatment and ‘water mining’ has also been identified as a key platform on which to base the technological development of such circular production systems 2 . Effective water treatment and material recovery can provide a double economic return. Every cubic metre of recycled or reused water results in a corresponding reduction in mains water demand and wastewater discharge. There are also benefits in terms of the energy and carbon footprints associated with material recovery when compared with primary extraction and processing, together with further environmental benefits arising from reduced waste disposal impacts. In addition, researchers are increasingly identifying food processing and supply chain waste streams as a major resource for the development of bio-based products and processes, suggesting that the valorisation of food waste should focus on both commodity and higher-value speciality products.
16
:ERO LIQUID DISCHARGE :,$ IS A TECHNIQUE BY WHICH LIQUID waste streams are eliminated. Instead of being discharged at the end of the treatment cycle, any wastewater is purified and recycled, while other residues, which often include the type of valuable by-products mentioned above, are extracted. 6ARIOUS PROCESSES ARE EMPLOYED IN :,$ INCLUDING membrane bioreaction, reverse osmosis, electrolysis, filtration and more. However, evaporation is also a key process, both in order to concentrate residues sufficiently to allow their economic extraction or physical removal, and as part of the water purification process. However, solid-liquid mixtures are complex and it is important that the first stage of any potential project includes a research study to evaluate the nature of the waste stream/s and the saturation levels required. In laboratory experiments, HRS evaluates the maximum concentrations that can be reached for different temperature regimes. This then determines the type of equipment we design.
THE IMPORTANCE OF EVAPORATION (23 (EAT %XCHANGERS HAVE BEEN INVOLVED IN :,$ PROJECTS IN Europe using evaporation systems, including the recovery of potassium and sodium sulphates from organic brine waste streams. A typical HRS process might consist of three steps as follows: 1. Evaporation/concentration (using one or more evaporators depending on the materials involved and the level of concentration required) to levels above the saturation point at high[ temperature. 2. Cooling down of the product to provoke the formation of salt crystals. 3. Further crystallisation in specially designed tanks and separation of the crystals that are formed to allow them to be processed for use. In the third step, a supernatant layer of concentrated solution remains after separation of the crystals. This solution is returned to the second evaporator for concentrating again to above its saturation point. CORRECT HEAT EXCHANGER CHOICE FOR PRODUCT RECOVERY Both the evaporation and cooling steps result in a high degree of material fouling on the inside of the equipment, so HRS Unicus Series scraped-surface heat exchangers are used to maintain thermal efficiency and remove fouling as it occurs. Coupled with HRS R Series coolers and customdesigned crystallisation tanks, the result is an efficient process which can work continuously without requiring scheduled downtime. In the example above, two evaporators are used to concentrate and remove pure water from the solution, which can be used elsewhere. The coolers and crystallisers produce solid crystals, and the remaining solution returns to the evaporation process. No liquid waste remains after the process, so that as well as recovering valuable salts, waste management costs are also reduced.
For example, at high temperatures more salts may be dissolved, compared to low temperatures.

AODD pumps
contribute to safety in mines AODD pumps are the workhorses of the mining industry – and have a key role to play in improving the safety of the mining industry. What springs to mind when you read the word “mining�? Probably high on your list is another six- letter word: “safety�. Yes, mining and safety go together like driving and SEAT BELTS 9OU CAN T HAVE ONE WITHOUT THE OTHER /THERWISE you are in big trouble. Unfortunately it hasn’t always been like that, as a trip back in time clearly illustrates. In 1931 in mines around the world – metals, non-metals and coal – there were an astounding 94,221 accidents, of which 1,688 were fatal. Thankfully, safety measures in mines have improved beyond recognition since then. However, the industry is far from achieving its goal of zero fatalities and injuries. In 2016, 7,045 accidents were recorded in mines, of which 26 were fatal. (Source: U.S. Mine Safety & Health Administration, updated December 2017).
In mining operations, pumps are pushed to their limits. Nearly all mining processes occur in extremely harsh, unforgiving conditions. Deep underground, you need equipment that operates reliably and consistently, and that requires minimum maintenance. Step forward the AODD pump! Thanks to their high reliability, AODD pumps are tasked with handling a wide range of solids, abrasives and particulateridden liquids. It would be impossible to name all possible applications, but some of the major ones are as follows:
It’s tough down there!
A number of design characteristics incorporated into a specific, clamped metal AODD pump contribute to an AODD pump’s reliability and make it a first choice for many of these tasks. High on the list is a shock-absorbing polyurethane screen base. This is perfect for absorbing the impact from solid particles. Another is increased internal clearances to prevent aggregate entrapment, which plays an important role in maximizing pump durability. Yet another feature is an integrated suction strainer that often comes with the option of plumbed suction.

HYDRA-CELL’S SEAL-LESS DESIGN ENSURES HIGH PRESSURE COOLANT EFFICIENCY Hydra-Cell High Pressure Coolant Pumps from Wanner are claimed to be the most energy efficient, machine tool coolant pumps available, measured at upwards of 80%, pump shaft to hydraulic power. Being true positive displacement pumps, they maintain this exceptional efficiency virtually irrespective of coolant viscosity and system pressure whereas screw and gear pumps, that rely on the pumped coolant for internal sealing, suffer a marked fall-off in efficiency as system pressure increases or fluid viscosity is reduced. With a Hydra-Cell pump, flow rate is directly proportional to input shaft speed, enabling a variety of accurate control options to be employed. Of great benefit in metalworking is HydraCell’s ability to handle fines entrained in the coolant that can cause major wear problems in pumps with dynamic seals, have bearings immersed in the pumped coolant or have close internal tolerances to maintain efficiency. With no close internal tolerances, no dynamic seals and no bearings immersed in the coolant, Hydra-Cell pumps are not prone to wear, minimising the need for maintenance and guaranteeing efficiency over a long life. And as an added bonus, Hydra-Cell pumps are able to run dry indefinitely with no adverse effects‌ a condition that destroys other pumps with dynamic seals‌ filter blocking remains undesirable but thanks

to Hydra-Cell it is not disastrous. With high pumping efficiency, long service life and minimal maintenance requirement, HydraCell seal-less, coolant pumps can truly be considered to be the high pressure coolant solution with lowest cost of ownership.

Eliminating
lubricant contamination from food processing machinery
Contamination poses serious problems for food and beverage producers. As production becomes more and more reliant upon automated machines, there is yet another source of potential contaminants: spilt or leaking lubricants. Phil Burge, Marketing and Communications Manager at SKF describes how food and beverage manufacturers can avoid this problem. Food and beverage is a major contributor to the UK economy. Early in 2017, the Food and Drink Federation commissioned the global professional services network operator, Grant Thornton, to undertake a study into the UK food and beverage manufacturing sector. Among its findings, the sector manufacturing gross value added (GVA) grew by 27% between 1997 and 2015 (compared with 13% for manufacturing as a whole over this period). In 2017, it accounted for 16% of total manufacturing GVA, making it the largest manufacturing sub-sector in terms of GVA contribution. Food safety continues to be a major concern for the sector. In common with other large economic contributors such as the automotive industry, product recalls can have serious business consequences. For food and beverage producers, product recalls arising from contamination events pose a serious threat to profitability, and as the sector grows its investment in automation and high-end processing machinery, so too does the risk of contamination from essential machine lubricants. The food and beverage industry estimates that between 15 and 25% of its entire maintenance budget is spent as a result of poor lubrication practices. Indeed, as much as 40% of all premature bearing failures in this industry can be tracked down to lubrication problems. While the food and beverage industry has any number of lubrication methods to choose from, not all are recognised under current hazard analysis and critical control points (HACCP) certification scheme, which is widely adopted throughout the industry. Implementing HACCP compliant lubrication management techniques that are primarily designed to eliminate contamination risk is therefore imperative for any food and beverage manufacturers. Several technologies have emerged to support HACCP compliant lubrication practices for food and beverage processing machinery containing bearings or transmission chain driven and flat top conveyor systems. This includes re-lubrication-free bearings, fully automated lubrication systems and NSF H1 certified lubricants. In general, the industry adopts three main approaches to avoiding lubricant contamination: the use of ‘food- grade’ lubricants; the use of sealed bearings or a move away from grease lubrication altogether, towards alternative ‘dry’ or ‘solid’ forms of lubricant technology. Food-grade lubricants are widely used, and are certified for food production punishing, inducing lubricant leakage from bearings and water ingress, both of which will shorten the life of a bearing. Even if a lubricant is food-grade, leakage into a food product is wholly undesirable, so efficiently sealed bearings are commonly used.

Bearings that are required to tolerate frequent wash-downs, such as those used in a poultry processing application, for example, are usually contained within corrosion- resistant composite housings, have stainless steel bearing inserts and a special multi-lip seal that prevents both grease displacement and water ingress. A poultry processing firm that was advised by SKF to use this type of bearing as a replacement for previously installed nickel-plated cast iron bearings, has seen bearing service life effectively quadrupled, with substantial savings made on maintenance and lubricant consumption as a result of the change. Solid Oil
MANUAL OR AUTOMATIC?
High temperature bearings
So-called ‘dry’ methods of lubrication have proved particularly beneficial to the smooth running of conveyors in baking ovens operating at temperatures of 180°C or higher. Bearings within ovens require frequent re-lubrication, because the high temperatures can degrade grease very quickly. A solution is to replace traditional grease lubricated bearings in these applications with like-for-like versions that use graphite cages. Here, tiny graphite particles are eroded from the cage and deposited as a thin layer onto the surface of the steel balls. Graphite is a very effective lubricant, and this thin, protective layer is enough to prevent the direct metal-to-metal contact that ultimately shortens bearing life. Although the cage is wearing away gradually, the effect is very slow and will usually last for the life of the bearing. Reducing the frequency of re-lubrication or eliminating the need for lubrication altogether, and having effective seals that protect against lubricant loss and damaging ingress of contaminants, will go a long way to achieving food safety. A good example is our Solid Oil encapsulated lubricant technology, which can be applied to virtually any bearing. This uses a polymer matrix saturated with lubricant that completely fills the internal space, encapsulating the cage and rolling elements and ensuring that food particles are kept out and chemicals and are virtually maintenance- free. This approach has been successfully applied on a bottle filling station, where previously used stainless steel deep groove ball bearings, although sealed and greased for life, were leaking grease and admitting water during the frequent washdown operations. Replacement our bearings with Solid Oil lubrication had a huge positive effect: bearing service life was extended from 12 weeks to two years, while maintenance costs were slashed and leakage almost completely eliminated.
Manual lubrication in the food and beverage sector raises a number of issues. It is labour-intensive and time-consuming, and imprecise manual metering may lead to over- or underlubrication which will have an impact on machine reliability and the cleanliness of the production environment. Underlubrication is likely to cause leakage of excess grease into the processing environment as bearing seals are compromised and, of course, poor lubrication will ultimately result in the premature wear of bearing rolling elements. Manual lubrication in food and beverage processing environments will also come up against a number of restrictions due to the nature of the operations and the products being processed. Certainly, there will be strict controls concerning access for personnel during production for reasons of safety and hygiene; the process equipment is also likely to be complex and not all lubrication points will be easy to access, leaving often vital parts of machines poorly lubricated or missed out altogether. An alternative approach is to automate the process of lubrication such that all points receive the marketing correct amount of lubricant, at the appropriate time while avoiding the intervention of maintenance staff. In essence, an automated lubrication system comprises easily accessible and refillable central reservoirs from where lubricant, oils or greases, are pumped in precisely metered quantities via a system of pipes directly to a machine’s lubrication points. Automated centralised lubrication systems can be installed at the time of machine installation or retrofitted to existing machines. Examples include our SYSTEM 24 and MultiPoint lubrication systems, which can be mounted for just one or many lubrication points to deliver the right amount of an appropriate lubricant 24 hours a day, seven days a week. The quantities and timing of automated lubricant deliveries will depend on the severity of duty and/or environmental conditions in the plant, and might follow an existing maintenance schedule that reflects these needs. In more advanced configurations, the lubrication cycle might be based on statistical machine data (such as the number of revolutions or other machine ‘events’), on data from real time condition-based monitoring systems or on the results of lubricant analysis. While lubrication is absolutely essential to efficient bearing operation, the food processing industry must make every effort to minimise, at best eliminate, the risk of product contamination from bearing lubricants. This means that processors are increasingly looking at alternatives to traditional food-grade grease lubricated sealed bearings, which have proved to mitigate such risks.

Preparing FOR A
safety audit
Flight passenger safety procedures are so engrained in our minds that it often feels like there’s no need to review them when we get on a plane. As health and safety becomes second nature to us, do plant managers feel the same about an emergency situation in their facility? Here, Clive Jones, managing director of thermal fluid supply and preventative management specialist, Global Heat Transfer, explains how plant managers using heat transfer fluid can prepare for a safety audit. In an environment where employees work in close proximity with potentially hazardous substances, such as thermal fluid, plant managers need to ensure their facility is safe. The best way to reduce risk in these facilities is to adhere to regulations. Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) and THE %XPLOSIVE !TMOSPHERE $IRECTIVE !4%8 137) outline the mandatory requirements for minimising safety risks and protecting workers from fire and the explosion of flammable materials present at the facility. WHAT IS A SAFETY AUDIT? A safety audit evaluates the condition of a facility and its practices to help ensure that it meets regulations and reduces any risk of incidents. Facilities with a thermal fluid heat transfer system need a regular audit to report onsite health and safety procedures because of the potentially dangerous substances present. There is no fail or pass when it comes to a safety audit. The auditors collect information about the facility and its safety procedures. From this, they make recommendations on how to correct the health and safety programme to comply with legislation. REGULAR MAINTENANCE As there is no failing an audit, plant managers do not need to prepare. However, plant managers should consider the main parts of an audit to understand where they should carry out regular maintenance in the facility. Auditors will base the audit on thermal fluid analysis to determine the condition of the oil. They must draw the sample when the fluid is hot, and the system is closed and circulating to ensure it is representative. If thermal fluid analysis results show that carbon is present in the fluid, plant managers may be able to restore the quality by carrying out fluid dilution or filtration. This will help to protect the system, continue production and extend the life of the fluid, while keeping maintenance costs down. Plant managers can also install a light ends removal kit (LERK) to remove volatile thermal fluid components that can be generated at high operating temperatures. LERKs can be used on systems of any
December 2018 – Process Industry Informer
size, but it is important that light ends are collected safely in the liquid phase of the system’s condenser and disposed of safely. As well as fluid analysis, plant managers should regularly check the condition of the pipework, flanged joints, gaskets and seals in the heat transfer system. They also need to check the pressure gauges to ensure that they are giving accurate readings. Carrying out regular checks will help ensure that any system leaks are spotted early. Plant managers should also look out for smoking flanges and leaking gaskets, as both are signifiers of a leak. These will all be checked during a safety audit and any faulty equipment will be recorded. This will have a negative impact on the audit results, but if left unmanaged could lead to something more serious, such as a fire or explosion. PROTECTIVE EQUIPMENT For heat transfer operations to run safely, the system’s insulation needs to be in tact to prevent employees from accidentally coming in to contact with the hot system. Spill kits, which include floor signs, hazard tape, pads, socks and a bin specifically designed for hazardous materials, should be replaced immediately after they have been used to ensure that one is always available in the event of a leak or oil spillage. General housekeeping is also important. Prior to a safety audit, plant managers should ensure that the facility is free from clutter. This makes it easier for the auditors to walk around the facility and see the condition of the system. MANAGING RECORDS Records should be kept up-to-date at all times, as plant managers need quick access to their latest thermal fluid sample results and service audits. Frequent thermal fluid samples should be taken and reported ready for review by the auditor. Best practice for representative sample analysis is at quarterly intervals. DURING AN AUDIT Many plant managers see a safety audit as a reason to check their heat transfer system and processes but having an efficient preventative maintenance plan that runs year- round should mean that preparation is in fact second nature. During the audit, the heat transfer system should be running at its normal operating temperature and conditions so that auditors get an accurate representation of the fluid.
An independent company should be appointed to carry out the audit, in order to ensure that the advice they give is impartial. However, an internal engineer should be present throughout the audit to witness any issues highlighted during the audit. The safety audit mainly focuses on the condition of the thermal fluid and the main components of the system, including the heater, expansion tank and pipework. The auditor may check the condition of the fluid, as well as how often the company takes samples. They also assess whether the company stocks the right level of top-up heat transfer fluid and whether it is stored correctly. When inspecting the system itself, the auditor concentrates on the condition of the system components and confirms whether there are any leaks. The auditor also checks that operation instructions for each component are easy to access. They check the area where parts of the system are housed, particularly the heater. This includes if the heater is in a separate room and whether it is locked or unlocked. They also look for where operation instructions are kept and if the plant has an emergency stop and drain down procedure. The auditors also review the maintenance programme at the facility, primarily how the plant manager tests and maintains the fluid and how the plant manager inspects and maintains the system. They then check procedures surrounding health and safety – from identifying risks, to managing them and communicating them. Auditors check how the company trains its staff about risk management and safety procedures to ensure everyone knows how
to safely work with the system and manage the heat transfer fluid better. WHAT HAPPENS NEXT? Once the auditors have completed their checks, plant managers need to focus their attention on the areas highlighted in the report. After addressing any issues, plant managers can invite the auditor back to look over any changes. The auditor then checks progress and ensures the relevant regulations are being adhered to. The best way to ensure safety audits are passed every time is by introducing a preventative maintenance programme. Regular sampling and visual checks of the system helps manufacturers meet health and safety regulations and prevent the risk of costly breakdowns and hazardous incidents. Implementation of a continuous maintenance programme, such as Global Heat Transfer’s Thermocare, gives plant managers the reassurance that their facility meets the regulations checked during a safety audit. Even though we may not pay close attention flight safety procedures, they are there for our benefit. Similarly, plant managers should pay more attention to regulations and audit recommendations when working with dangerous substances such as heat transfer fluid. Regular thermal fluid analysis and maintenance checks can help plant managers get off to a flying start during an audit.

By Duncan McPherson, CEO at leading gas engine specification and maintenance services, CooperOstlund
Generating off-grid energy The topic of energy is never far from the business and consumer agenda, and with good reason. Rising prices, uncertainty over supply and a focus on sustainability all mean that an innovative approach is needed. Duncan McPherson, CEO at leading gas engine specification and maintenance services provider, CooperOstlund, explains how generating off-grid energy may provide the solution. THE CURRENT DILEMMA There’s no getting away from the fact that our energy infrastructure in the UK is inadequate. The National Grid is dated, inefficient and widely considered unfit for purpose. Demand – especially in peak times – regularly overtakes supply availability. What’s more, with a ban now announced on coal power generation and an already- heavy reliance on power supplied from overseas countries, we’re clearly unprepared for what the future will bring. But the consequences of this could be devasting. Companies are already offered financial incentives to stop working when power is in short supply, and blackouts are a real threat, potentially grinding operations to a halt and irreparably damaging reputation with suppliers and customers alike. The unpredictability of energy prices can also lead to spiralling facilities management costs, hitting a company’s bottom line hard.
DECENTRALISATION AS A SOLUTION Considerable work is already underway to find an effective solution for the future, but a number of techniques are emerging to support industry in the short-term. From peaking plants and on-site energy generation solutions, to blended energy programmes, off-grid generation is quickly becoming the stop-gap. Indeed, it’s predicted that decentralised energy will grow 130% by 2030, representing 14% of the UK’s total generation capacity 1 . And with this growth comes benefits, ecentralised energy, the same study finding that on-site energy generation could help UK businesses save around £33 billion by 2030. Combined heat and power (CHP) and energy from waste are predicted to deliver the greatest savings of £20bn. As the UK leader in the specification, installation, optimisation and maintenance of gas engines (in particular, CHP) we’re at the forefront of this energy revolution, which is heralding a new era in how businesses are adapting to market and regulatory challenges. Effectively a mini power station, CHP engines are almost twice as efficient than traditional grid connectivity… and much more secure! By generating both heat and power (in one single process) at the point of consumption, users benefit from lower energy costs compared to sourcing electricity and gas independently from the grid. Over the past 12 months, we’re experienced a dramatic increase in the number of engines installed nationwide. As well as peaking plant setups (off-grid CHP engines that automatically pump electricity into the grid in times of peak demand), fitting CHP engines in industrial scenarios (to replace mains supply) is becoming popular.
26
An example can be seen in one of our recent peaking plant installations which saw three, 2.7MW CHP gas engines installed at a site in rural Derbyshire. Operational since April 2018, the plant is running at optimum efficiency and generating more than 8.1MWeenergy to support the National Grid in times of peak demand.
with potential interruptions to energy supply. The fact that equipment can be planned, procured and installed to take factors such business type, site size and energy requirements into close consideration, means that businesses can tailor their energy provision to precisely meet their needs – not just now, but also for the future.
THE BENEFITS OF OFF-GRID
LOOKING TO THE FUTURE
Financially, the numbers add up. In fact, by turning gas into electricity rather than sourcing power direct from the National Grid, companies can experience significant savings because simultaneously generating both heat and electricity from a single fuel source, is a highly cost-effective alternative to traditional mains supply.
The future of our energy infrastructure is far from clear; however, innovation is providing new and improved ways to generate power without relying on mains electricity and the shortcomings of The National Grid. While a long-term solution is essential, for now, short-term stop-gaps are already revolutionising our energy landscape.
The secret to CHP’s success is this heat element of the process. By using waste heat, CHP plants can reach efficiency ratings of over 80%, compared to UK gas power stations, which range between 49 and 52% and coal-fired plants at around 38% 2 . As the gas network is under less demand, this approach also improves energy security. When it comes to peaking plants, the ability to inject power into the grid in periods of high demand is hugely valuable. Alongside preventing blackouts, this again improves energy security and ensures our national energy demand can be met.
Embracing alternative energies, such as CHP, can offer businesses a real lifeline in these uncertain times. By producing their own off-grid energy, companies can not only ensure that their operations run smoothly, to budget and without interruption, but also that they’re doing all they can to boost their sustainability credentials in the process. 1 Utilyx: Coming 2 Association for Decentralised Energy
Undoubtedly, one of the main benefits of decentralisation is the pricing stability it offers against grid reliance. By self-generating energy and knowing the costs involved, businesses can safeguard themselves against the challenges of unpredictable wholesale power prices or sharp increases in network costs. This subsequently protects the bottom line, and therefore profits, and mitigates the risks associated

Preventative Maintenance Matters
M
as winter comes calling
artin Geobey, Managing Director, UK & Ireland, at IMI Precision Engineering, outlines how preventative maintenance programmes can help alleviate unforeseen and costly downtime issues as manufacturers get their plants ready for the winter months.
PREVENTATIVE MAINTENANCE CHECKLIST FOR PNEUMATICS To help you, this is a standard preventative maintenance checklist to ensure you are on top of your pneumatic maintenance programme: s #HECK YOUR PISTON ROD HAS NOT BEEN DAMAGED BY material debris, rust or corrosion. s 2EMOVE DEBRIS BUILD UP ON THE PISTON ROD TO PREVENT nose and wiper seals leaking.
The winter months present fresh challenges when it comes to keeping manufacturing plants running and productive. Busy production periods in the run up to Christmas, reduced maintenance staff numbers as they use up annual leave, and the negative impact of cold and adverse weather conditions on machines and plants, can be a combination that is problematic to manage. The answer, therefore, to reducing the potential for maintenance-related issues to emerge during winter is to plan. By planning and implementing a preventative maintenance programme, businesses are able to spot and solve small issues before they have a chance to make a bigger impact.
2. LEARN FROM EXPERIENCE Once a preventative maintenance programme is established, not only will the health and performance of the manufacturing output be enriched, it also sets a solid foundation for an ongoing cycle of continuous improvement. Insight gained from analysing how important components are performing in different environments; how they react to temperature changes and wear and tear, how they deal with altering workload requirements, can help inform and guide plant operation and enable manufacturing organisations to become even more efficient and productive.
This approach puts less stress on maintenance teams to complete jobs within a short timeframe, and reduces the risk that tasks are not always rectified satisfactorily when rushed reactively.
It can also identify high energy consuming components and provide an intelligence-based opportunity to replace them with more efficient solutions, or even take a holistic view about where energy and cost can be saved through the whole production process.
Preventative maintenance scheduling means that all elements of the production process are under constant review to eradicate instances of unexpected failure.
A prime example is the common use of compressed air as a vital resource for manufacturers.
Manufacturers should approach continual preventative maintenance to optimise operational efficiencies for the long term. Examining three key areas will help them to achieve this.
1. USE DATA FOR INTELLIGENCE-BASED DECISION MAKING With the advent of industrial digital technologies (IDTs), organisations now have access to more information about their components’ health and performance than ever before. Data from smart, connected products placed within production lines can deliver a real time, highly accurate view for operators when it comes to assessing performance against critical KPIs, and whether remedial action is required before issues occur. A recent Government report estimated that the use of IDTs could, help reduce machine downtime by between 20 and 30 per cent and reduce plant maintenance costs by between 15 and 25 per cent.
Despite its broad use, it remains one of the most expensive forms of energy with a typical 500 litres/sec unit consuming ÂŁ40,000 of electricity per year. The smallest unidentified and unrectified leak within a compressed air system in an industrial environment will make equipment and production less efficient and significantly increase costs. Recording the data extracted from components is just half the story. It is using the[ experience for the selection of added value solutions that will make the real difference for manufacturers looking for a competitive edge.
3. ADDED VALUE SUPPORT In the unfortunate event when an issue leads to unplanned downtime, manufacturers should be confident that their supply chain is robust, responsive and quality-led. Often the need to obtain spare parts quickly, can have a direct impact upon the speed which an issue is sorted, and the total financial cost of downtime. Making sure your supply chain offers sufficient stock levels, has easy to access technical support and has the back-up of field engineers (if required) can be the ultimate safety net.

NO EMISSIONS AND FLAMMABLE SOLVENTS New water-miscible bonded coatings for elastomers and O-rings Klüber Lubrication now offers new watermiscible bonded coatings free of flammable solvents for the life-time dry lubrication and pre-start lubrication of special applications. Apart from the well-known benefits of dry lubrication, the new product lines significantly improves the sliding and sealing effect of O-rings due to the reduced permeability to gases and liquids. The new product line complements the product families Klüberplus for easier assembly, Klüberflex for dynamic applications and Klübertop for use in the food sector.
“In O-ring lubrication bonded coatings have to fulfill various tasks, e.g. provide a separation effect, simplify assembly, or withstand dynamic loads like in valve lubrication”, explains Rudolf Zechel, Manager Special Projects at Klüber Lubrication. “Bonded coatings for components in the food and drinking waters sector also have to comply with FDA and drinking water requirements. Our new product line combines the advantages of our proven bonded coatings with the additional benefit of being free of flammable solvents, which is why no emissions are released during application.”
Bonded coatings used for O-rings offer numerous advantages. O-rings can be separated easily during automated assembly. They ensure a high level of safety as leakage or twisting of O-rings during assembly is prevented and joining forces are reduced. In addition, contamination of materials. sensors due to lubrication can be ruled out. Bonded coatings can also be used for colouring to minimise the risk of confusion with different sizes or materials. In dynamic applications, dry-lubricated O-rings significantly reduce the friction value and increase the service life of components. This applies to seals subject to several hundred revolutions per minute as well as to low-speed applications such as opening fuel filler caps or operating a bell button. Such applications are efficiently protected from freezing in winter time by using bonded coatings. For more information contact Klüber Lubrication, Andreas Hasslinger, Germany.

AOAC-RI CERTIFIES HYGIENA ULTRASNAP™ SURFACE ATP TEST
Certification one of only two ATP validations worldwide, demonstrates validity of tests for microbes. Hygiena, a global leader in rapid food safety and environmental sanitation testing, today announced the AOAC Research Institute, one of the world’s most recognizable product certification organizations, has issued its Performance Tested -ETHOD3- CERTIlCATE TO THE 5LTRA3NAP Surface ATP Test for identifying the possible presence of microbial contamination. As required for AOAC-RI certification, Hygiena used a third-party laboratory to test the results of UltraSnap on stainless steel surfaces in five food matrices, essentially reproducing a food processing facility.

ENHANCE STEAM QUALITY WITH NEW HACCP GUIDE s &OOD AND BEVERAGE MANUFACTURERS DO NOT ALWAYS include steam within their HACCP s 9OUR QUICK START GUIDE TO INCLUDING YOUR STEAM system in your HACCP details seven steps to help ensure the quality of your final product is achieved at all times s 'UIDE STRESSES THE IMPORTANCE OF TESTING STEAM as an ingredient, just like any other. Those concerned with quality within the food and beverage industry will already be very familiar with the concept of Hazard Analysis Critical Control Points (HACCP), though many will be less familiar with including steam within their HACCP approach. The launch of the new guide aims to provide a stepby-step process to helping facilities managers ensure the quality of their final product is achieved at all times by including steam within HACCP. Authored by Francisco Pedrosa, Regional Clean Steam Specialist at Spirax Sarco, the new quick-start guide aims to offer a helping hand to plant operators in the food and beverage industry in understanding and including steam within their HACCP. Your quick-start guide to including your steam system in your HACCP provides seven easy to follow steps

for operators to end the overlooking of steam within HACCP-based approaches. Steps include: Identifying critical control points, create monitoring processes, and define verification procedures, among others.
“By including their steam system in a HACCP, plant operators can better maintain, and feel more confident about, the quality of their plants output.” says Francisco. “This guide aims to help those operators ensure that the quality of their final product is achieved at all times – reducing waste and energy costs”. “All too often I find myself speaking with plant operators at food processing plants who know that they should be including steam within their HACCP approach but lack the knowledge to do so. It is my hope that this guide will help to mitigate the likelihood of physical, chemical, and biological hazards within the food industry and to create a manufacturing sector that places the proactive management of steam quality and food safety at its core”.

The test results showed very low limits of detection (down to 0.77 relative light units {RLU}, the measure generated by ATP-based luminometers). The results also showed that UltraSnap was able to detect ATP from surface soiled by food and beverages, at dilutions of 1:1,000 or lower. The UltraSnap was shown to be highly selective for ATP, stable and consistent, and to have no statistically significant variability. The validation marks the first of Hygiena’s ATP-based test products, and only the second ATP monitoring device, to receive an AOAC certification. We are delighted that the most used ATP system around the world has been verified and validated for its accuracy and sensitivity by the AOAC,” said Steven Nason, Chief Executive Officer of Hygiena. “This validation is helpful for certain customers and government bodies around the world and validates the claims we have been making on the system for years. ATP testing is the fastest and most effective way for food processing facilities to determine cleanliness levels and accurately identify areas that need attention before food is processed which helps keep our food supply safer.” To find out more about the EnSURE™ quality monitoring system visit: www.hygiena.com/ultrasnap-food-andbeverage.htm To find out more about the UltraSnap™ Surface ATP test visit: www.hygiena.com/ensure-food-andbeverage-processors.html For more information contact Camarillo, Watford, Herts Tel: +44 (0)7534 613974 E-mail: komal@hygiena.com
