Coriolis Mass Flow Application Story – Wax Production in UK UK wax manufacturer Kerax Limited has installed an OPTIMASS 7300 mass flowmeter to improve the accuracy of production processes at its plant in Chorley, Lancashire. Application: Kerax produces a variety of different waxes to be used in making castings and as ingredients in products such as adhesives. Each formulation requires the blending of two or three types of wax plus a number of additives. The mechanical meter previously positioned on the input to the blending vessel was not able to provide the accuracy needed for Kerax’s increasingly stringent process control. Problem: The wax flowing through the meter can vary in density from 0.8 to 1.0 kg/litre and in viscosity from 5.5 cP to 1,200 cP. It can be flowing at rates varying from 1.8 to 15 tonnes / hour with pressures from 1.4 bar to more than 4.1 bar at temperatures ranging from 20 to 120°C. Solution: OPTIMASS 7300-T 50 The installed OPTIMASS 7300 Coriolis mass flowmeter is capable of handling the wide variation in process conditions whilst still delivering accuracy of +/- 0.1 per cent. STRAIGHT TALK To maintain a consistent product temperature, the OPTIMASS meter is fitted with a heating jacket that can be fed with hot water or steam.

Application Story – Siemens Gasification Test Rig STRAIGHT TALK The Siemens gasification centre in Freiberg, Germany, is one of the most comprehensive gasification test facilities in the world. Its gasification reactor is rated at five MWth and can be adjusted to different feedstock conditions. The facility also includes a range of feedstock preparation systems and related gas cleaning process units. A test rig for large-scale, high-pressure feeding tests and further equipment for coal and slag analysis (e.g. fluidization and viscosity) complement the facilities. With this equipment, a broad range of test conditions can be simulated. For the examination of fouling in heat exchangers, a test rig was designed to gain experience when preheating process water up to 220°C. Thermo oil is used as a heating medium in the heat exchanger. Both the monitoring of temperature and a reliable monitoring of the volume flow are decisive factors for the evaluation. An OPTIMASS 9000 from KROHNE was installed to control the thermo oil volume flow. The mass flowmeter records the volume flow of the thermo oil at 230 °C and 10 barg. The maximal permissible temperature of the thermo oil is 300°C.
