Optimass Application Story

Application: Beer Brewing at Grolsch in Holland

When Grolsch built their new state of the art brewery at Enschede, they equipped it with KROHNE flowmeters, including OPTIMASS meters for the more demanding applications where there is high viscosity or no conductivity.

In the brewery applications this includes dosing liquid sugar and hops and for measuring carbon dioxide levels in the cold recovery system.

OPTIMASS is capable of high measurement accuracy of 0.1 % for fluids and 0.5% for gasses. Our mass flow meters can measure density and volume flow as well as calculating Brix or Plato with the concentration option.

Grolsch’s tests actually showed better than 0.1% accuracy when dosing 8 kg batches of hops

Application Note

Why use Optimass?

Due to the very high viscosity and the subsequent need to reduce the pressure drop, it is necessary to choose a meter whose operating point lies in the lower range of the flow rate.

In this case Optimass shows a marked improvement over the competition.

Zero Stability

Various doses were checked against a certified scale. The following diagram shows how impressive the performance of the new Optimass was. The low flow cutoff was switched off during the tests.

CERVECERÍA BAVARIA S.A. is a beer monopoly in Colombia which ranks number 10 of the largest breweries world wide. They have seven plants in Colombia, dominate the beer market in Ecuador and Panama, and produce more than 60% of beer consumed in Peru. Among their plants in Colombia, they have CERVECERÍA LEONA, one of the more modern plants in South America, built in 1994. Because BAVARIA is focused on increasing efficiency, they want to measure several points of the process to detect process loss. So at LEONA they instigated a pilot trial using mass flow meters for wort in kitchens as well as for bright beer after filtration.

Through local representative Control Engineering S.A., KROHNE beat E+H, ABB and Siemens (Danfoss) with the best technology; the lowest pressure drop on process and a reasonable price. But what really impressed LEONA was the wide flow range Optimass could handle, because production will be doubled over the next 5 years, and our meters could make the transition.

Application Story – loading of milk in FranceCheese Producers sometime have to sell excess milk or buy in from other suppliers according to their production demands and quotas. They have various options available to measure this.

Application :To accurately record the quantity of milk loaded into the tanker trucks from the storage areas of the factory. As the milk is pushed through the pipes by water, density measurement is used to determine the cut-off point so only milk goes into the tankers.

Why did the customer choose KROHNE:The KROHNE sales team in France were able to use their experience to help the customer to choose Coriolis mass flowmeters instead of the weighbridge option, and to demonstrate to his customers that this was a reliable billing solution, without having to resort to custody transfer transactions.

Model chosen:The OPTIMASS 7000 has the technology. With its single straight tube, it is totally cleanable inline and approved for hygienic applications. The density measurement is used to limit the range of density between 1025 Kg/m3 and 1040 Kg/m3, allowing differentiation between the passage of the milk and the water.

Benefits to the customer: Simple daily operation; reduced investment cost with the meter installed online in the loading pipes, avoiding the need for civil engineering works to build a weighbridge.

Optimass

One of the UK’s leading speciality vegetable oil refineries is relying on the installation simplicity and accuracy of KROHNE’s revolutionary OPTIMASS Coriolis mass flowmeters to monitor the flow of their products into road tankers.

Application Vegetable oils with a variable loading temperature and a viscosity of between 8cp and 100cp, are pumped from storage tanks at an average mass flowrate of 60 tonnes per hour using centrifugal pumps. They are routed through two separate pipework systems, and pass through the flowmeters before reaching the loading points. The OPTIMASS meters send a pulse output to a batch controller to measure the mass of oil being pumped; when the totalised mass flow reaches a predetermined level the batch counter stops the pumps.

Above The OPTIMASS meters installed directly in a two metre high inverted u-bend to ensure there are no vapour inclusions within the meter during operation Why KROHNE?

This customer, Tovarna Sladkorja Ormoz, is a sugar producer in Slovenia. They use lime milk as a flocculent and require the concentration of lime milk to be constant. In order to achieve this they purchased an Optimass T 50 with the Baumé concentration option. Due to the abrasive nature of lime milk, transition pieces were installed. As the Optimass T 50 meter is measuring at the upper velocity limit (6 m/s) for abrasive applications, after three months' operation the KROHNE agents in Slovenia made a resistance check and removed the instrument to see if any damage on the transition piece or instrument had occurred. More than 47,000 tons of lime milk had passed through the instrument but there was no trace of wear, either on the transition piece or on the instrument. The customer was very satisfied with the measurement.

Application Story – Bio-Ethanol Production in US & CanadaFuel Ethanol (200 Proof) is a renewable, clean burning & high octane fuel that is better for the environment than gasoline. It is also bio-degradable and far less toxic than fossil fuels and can be used on its own (E100) or blended with gasoline (E10, E85 etc).

Ethanol can be produced from starch/sugar rich feed stocks such as grains/cereals (corn, wheat, rice etc) , potatoes, cassava, beet/sugar cane and today even from cellulosic biomass sources viz. wood chips, switch grass, corn stover's, municipal waste, recycled paper etc.

Of all these feed sources the Dry Grind/Milling process used for corn (or wheat) feed is the most popular in US & Canada. Typical OPTIMASS applications on a Dry Grind/Milling process (shown on right) include density measurement for slurry tanks , liquefaction mash, syrup draw , rectified & final proof measurements.

Liquefaction Mash(feed preparation for fermentors)

Slurry #1 Density ( Slurry Preparation)

Corn Slurry and syrup drawn from evaporators can be extremely nasty & viscous and will clog almost any bent tube designs - it is here that the single straight tube Optimass offers significant benefits.

Also lower pressure drop is a desirable feature as energy optimization is of utmost importance on these high energy intensive processes. It are for these reasons that Krohne is able to demonstrate value over our competitors.

Krohne Inc has over 60+ installation ( and 50 more on order) of OPTIMASS 7000 series (S25/S50 tubes) on the corn slurry/mash & syrup applications . Additionally on each of theseplants our 7000 series (S15 tubes) are installed on liquid ammonia feed lines that feed nutrients into the slurry tanks andfermentors.

Why KROHNE:The only Straight Tube Tantalum meter on the market!


Application Story Varnish Production at BASF Coatings AGBASF Coatings division develops, produces and markets a range of top quality innovative vehicle, car repair and industrial varnishes and coating materials for buildings and offers the corresponding coating processes. The Münster site is one of the biggest varnish plants in the world with a total area of 400,000 square meters.

In order to operate the mobile paddle mixers used in the colour grinding process without supervision over 36-48 hours BASF used a flowmeter to trigger a leakage alarm. This meter needed to fulfill high specifications in terms of accuracy. The properties of the media made things even more difficult. The raw materials for varnishes are high-viscosity media which are processed at a low flow rate. They have viscosities of 7000mPas and over, and are also shear thinning - their behavior changes with the flow rate. The DN 40 flowmeters also have to cope with high pigment contents. BASF Coatings did not want to risk any further pressure loss otherwise they would have to increase the performance of the pump. BASF Coatings thus opted for the OPTIMASS, a mass flowmeter which is virtually made for this application thanks to its straight-tube design.

The grinding system is designed for a flow rate of approx. 5000kg/h. Communication with the PLC takes place via the OPTIMASS's 4…20mA signal output. Every 90 seconds the PLC saves a flow measurement and compares it with the subsequent values. If there is a difference of 360kg/h, the system is automatically shut down. At present, further tests are underway to halve the leakage value.

• Less pressure loss• Less abrasion• Suitable even for large flow volumes• Wide measuring range• No risk of blockage

Application Story - Liquefied gas measurement in UK

The liquefied gas is distilled into several fractions which are used as active ingredients in pharmaceutical products. It was essential that F2 Chemicals found a way to measure the flow of the liquid reliably to ensure the consistent, high quality of its products. The measurement technology F2 Chemicals previously used to measure the flow of liquefied perfluorobutane and acetone did not provide the reliability which was critical for F2’s process.

Specialist chemical manufacturer F2 Chemicals Ltd has installed KROHNE’s OPTIMASS 8000 Coriolis mass flowmeter to improve the reliability of liquefied gas flow measurement at its plant in Lancashire.

Perfluorobutane and acetone are contained in 100 litre industrial cylinders and are charged into the distillation column and refluxed through the OPTIMASS Coriolis mass flowmeter at flow rates of between 40 and 200 kg/hour and at pressures of between 2 and 7 bar. The temperature of the liquefied gas varies between -5°C and +15°C. A 20 mA signal is taken from the OPTIMASS and fed into a DCS. The reading is manually monitored and the distillation process adjusted according to temperature.

Measurement reliability improved significantly since the KROHNE OPTIMASS 8000 Coriolis mass flowmeter was installed.

F2 Chemicals installed KROHNE’s OPTIMASS 8000 Coriolis mass flowmeter because of its ability to measure liquefied gas reliably and accurately at low temperatures. Its twin “u”shaped measuring tubes provide excellent signal-to-noise ratio and measurement turndown. This was important considering the low pressures of the gas being measured.

Application Story: Liquid Sulphur measurement in Russia

Ammofos plant in Cherepovets

Ammofos AG at Cherepovets is one of the leading Russian manufactures of phosphate fertilisers, and part of the chemical conglomerate JSC Fosagro AG The focus of the company is the production of sulphuric acid. Raw materials used in production are sulphur and pyrite.

OPTIMASS 7050 T25 mass flowmeters are used to measure the flow of molten sulphur with a temperature up to 145°C.

Problem: The temperature has to be kept above 130°C to prevent the sulphur from hardening and crystallising, and other measurement systems encountered problems.

Solution: The Optimass meter with its efficient heating jacket prevents the product solidifying. The great advantage of the single straight tube meter is its low pressure drop. The other advantage is that, if the product does solidify the straight tube is easy to clean out and restart the process.

Polymerising Vessel

Water and Initiator 22 Bar

Asahi Glass Fluoropolymers UK Ltd installed four KROHNE OPTIMASS 7000 T10 flowmeters to measure heavy gas flow at its polytetrafluoroethylene (PTFE) manufacturing plant in Lancashire. Each OPTIMASS replaced 2 previous measuring devices for pressure and temperature.Tetrafluoroethylene (TFE) is a dense, almost liquid, heavy gas used in the production of PTFE.

The TFE gas is produced in a separate area of the factory and pumped into the PTFE manufacturing plant through a common pipeline 24 hours per day. The common gas feed is then split into four lines to produce different grades of PTFE, each of which is fitted with an OPTIMASS flowmeter.

Process ParametersMedium : TetrafluoroethyleneFlow Range : 0 ... 20 kg/minDensity : 144.8 kg/m3Viscosity : 0.0135 cPTemperature : 4 °CPressure : 24 bar

The OPTIMASS T10 meters measure the TFE gas into a polymerising vessel with great accuracy. The gas is then combined with water and initiators in the reactor to produce the PTFE slurry which then has the water removed to leave the end product.

Advantage for the customer:With the installation of these meters AGF improved the accuracy of gas measurement and eliminated the need for two measurement devices.

Sand Separation

INDUSTRY: MINING COUNTRY: SWEDEN METER: OPTIMASS T40

Råda Sand AB is a producer and supplier of fine sand to various industries including concrete, filtration manufacturer etc. To be able to get the fine sand out of the water, they have to add the right amount of flocculent chemicals to settle the sand. The mass concentration controls the whole process in a ratio with the volume flow. We supplied the customer with an Optimass MFM7050 T 40. Application: Flocculent Dosing Why KROHNE? Problem The customer required accurate dosing of the flocculent (inorganic coagulant) due to the high price of the flocculent and to improve efficiency. Solution The only equipment suitable for the customer was the Optimass due to its single straight tube, which is less susceptible to abrasion.

The fluid is very abrasive due to its sand content (<10%) so the cones on the inlet and outlet sections have to be narrow. The Optimass is used to measure the concentration of the sand mixture to provide an input to the controller which governs the ratio of flocculent addition to the mixture. Process Parameters Media: Sand/Clay slurry (<10% Sand >90% Water) Pressure: 2 barg Temperature: 15°C (Ambient) Flow capacity: 15000 l/h Sand content: 800 kg/h

Application Story

Salt Mining in AustriaShortly before its 25th Anniversary, Saline Austria in Ebenseemodernised its installation in order to optimise production processes and minimise environmental impact.

The brine tanks accumulate a slurry of chalk and gypsum at the bottom which has to be drawn off periodically. This led to a lot of the brine also being lost. However with the use of Optimass meters to measure the density, the valves can be closed as soon as pure brine is measured. The slurry density is around 1.3 kg/l and drops to 1.15 with pure brine.

The Adaptive Sensor Technology of Optimass removes the problem of external influences affecting measurement by using its own internal mass as a self compensating mechanism therefore responding quickly to changes in density.

Additionally a KROHNE Optimass is helping to improve the environmental impact as the waste water slurry from the process is no longer discharged into the Traunsee Lake but pumped back from Ebensee via a 20 km pipeline where it is forced into the salt caves of Bad Ischl which in turn displaces new brine. This is then returned by a separate pipeline. Here also, the KROHNE meter is being used for density control.

Application: Salt production

Why KROHNE?Problem: Loss of brine when slurry drawn offSolution:Prompt shut-off with Optimass density measurement

Paper Coating Plant produced by OEM customer, BVG for Paper Mill in Germany

Application: Discontinuous Paper Coating Our customer BVG in Greifenberg is an important Original Equipment Manufacturer (OEM) for the paper industry operating world wide. The installation of this extremely compact discontinuous coating kitchen was made by BVG’s Dr. Bauer at a paper mill in Germany. BVG have also developed innovative continuous coating plants for other customers with on line coating and on line satinage using our Coriolis meters. Problem The problem for the end user lay in the recipe for the coating colour. There were always bonding problems between the background and the coating. This could have been caused because the required level of dosing accuracy was not achieved with the previously used positive displacement meters. Getting accurate and responsive measurements of the highly viscous and dense products batched such as clay, latex, carbonate and dispersants was difficult. Solution

Density Measurement of Carbonate Slurry in the Paper Industry

The measurement of the density of Carbonate slurry has evolved considerably in the last few years in the paper industry and in particular at this customer in Finland.Initially the density was measured using Radiometric density meters and, combined with an Electromagnetic flowmeter, the mass flow was calculated. Here Berthold density meters and KROHNE IFM5110F Magnetic Flowmeters were used.Later on this measurement method was discontinued due to the ‘percieved’ dangers of Radiometric measurement and Single Straight Tube Coriolis meters were used to replace this technology. The process involves and evaporation process where the slurry is continuously circulated till the correct density is achieved in the evaporator. The Carbonate slurry is then pumped to a storage tank. A KROHNE 300 G+ was used for this process. In the initial production and mixing of the slurry and 800G+ was used. Further enhancement of the process was made using the Multi I/O option in the mass meters. This provided the plant engineers with more data with respect to the process, apart from density, eg temperature, mass flow etc.Later orders of mass flowmeters from KROHNE had the Profibus PA option which gave the plant engineers more flexibility in the control and monitoring of the plant.

New Evaporator

When it was decided to install a new evaporator the natural progression was to use the new Optimassmeters from KROHNE.

This project was started in October 2002 and fully commissioned by May 2003. Here an OptimassMFM7051 T40 with Profibus PA was used.

KROHNE Magnetic flowmeter Model IFM 5090 WITH Profibus PA was used for water addition to the process.

Optimass

One of the biggest Shell petrochemical production facilities in Europe is at SHELL Berre (close to Marseille), Application: Truck loading The customer needs to load the exact quantity of SAP oil into the tanker to avoid any overloading. The trucks are then weighed on a weighbridge to get a custody transfer measurement of the mass. If there is an overload, the truck must come back to an offloading station, losing valuable operating time. If the tanker is not totally filled, then transportation costs increase.

The previous installation was less than ideal, and 7 larger meters were replaced with Optimass T 40 and T 50 meters without any pipeline modifications. This was a requirement, as Shell was not able to stop the loading stations in order to do the work. The measurement results were immediately excellent without any special adjustment or field calibration of the meter. For a 26 ton fill, the measurement accuracy improved to ±0.2% with Optimass from the previous ±0.8 to 2.5%.

ISPAT Nova Hut a.s. is one of the largest metallurgic plants in the Czech Republic. It is an integrated steelmaking concern with a metallurgical production and large engineering shops. The metallurgical production is of a mass character, the main products being welded and hot-rolled seamless steel pipes, long products and wire rod, hot rolled sheets and strips. The engineering production (e.g. steel mining supports) is geared for batch production. Their coking plant is the largest coke producer in the Czech Republic.

ISPAT Nova Hut has been using several hundreds of KROHNE magnetic inductive flowmeters and flow controllers (mainly on water measurements) and additionally ultrasonic flowmeters (on demineralised water and tar), level radar (blast furnace stock level, hydrochloric acid level measurement) and mass flowmeters (fuel oil, top gas and steel sludge measurement). All instruments have been subjected to demanding operating conditions.

In the blast furnace, during the pig iron production process, a lot of top gas is generated. The gas (with temperature 200 – 500°C) contains from 30 to 100 g/m3 of dust. The gas is cleaned with sprinkling water, which then flows into settling basins. Here the mud settles and then it is pumped first to thickeners and after thickening to a separator. For the process control it is necessary to know the density of the mud pumped from basins to thickeners and from thickeners to the separator.

The customer had been using nucleonic density meters for 10 years. These meters require special approvals and checks and a lot of maintenance. Moreover they could not be in operation without product flow. For this reason the customer decided to test 2 KROHNE mass flowmeters Corimass MFM 4085 G+ - 1500 G. After 6 months´testing, 8 pieces of Optimass T50 mass flowmeters were ordered.
