Level Measurement Solutions for Oil Filtration Skids
Filtration is the process of removing contaminating components from process media. Filtered media can include air, steam, gas, and liquids in a broad range of viscosities. Liquids commonly filtered include water, solvents, heat transfer fluids, hydrocarbons, pharmaceuticals, edible oils, food products, fuels, and lubrication oils. The filtration process is essential to a variety of industries, and ensures a purified end product, smoothly running machinery, and minimal equipment downtime.
This blog post, part of the Magnetrol® series on modular skid systems, discusses oil filtration, one of the most common filtration applications. It also highlights level measurement solutions for oil filtration systems configured as skids.
Process Schematic
Hydraulic oil, turbine oil, lubrication oil, gear oil, transformer oil, and diesel fuel are commonly filtered. Maintaining fluid cleanliness increases the life of critical components on all rotational equipment. A fuel or oil filtration skid typically incorporates a sequential, multifunction filtration system for dehydration, degassing, particle removal, and removal of volatile matter. Fuel and oil skids are developed for specific types of kinematic viscosities and flash points. Stored fuel or oil typically passes through the filtration process and on to a day tank for storage.
Level Measurement Solutions
下麵是常見的水平easurement applications for fuel or oil filtration skids and their associated level measurement solutions:
- Fuel/Oil Storage Tank:Large tanks are typically not included on a filtration skid; though smaller, holding tanks for separator feed may be. Safety-certified level switches and transmitters are required for fluids with low flash points. For continuous level, the Eclipse® Model 706 guided wave radar transmitter is recommended on small tanks; the E3 Modulevel® displacer transmitter or the Pulsar® Model R86 radar transmitter is recommended on large tanks. For point level, the Tuffy® II float switch or the Echotel® 961/962 is recommended.
- Water Separator Vessel:The first step in filtering an oil or fuel stream is to separate the oil or fuel and the water into separate streams. Interface level measurement will actuate a valve to adjust vessel level. For continuous level, the ECLIPSE Model 706 guided wave radar transmitter or the E3 MODULEVEL displacer transmitter is recommended. For point level, an external cage float level switch or the Thermatel® TD2 thermal dispersion switch is recommended.
- Wastewater Tank:從分離過程中的廢水收集在監控的專用收集罐中。在高水平時，水平控製致動傾卸閥以將乐动体育下载水路由到排水管或額外的處理。對於連續水平，建議使用echotel®型號355非接觸式超聲波發射器或型號R82雷達變送器。對於點電平，建議使用回聲型910超聲波開關。
- 日用油箱的燃料或油:The day tank is typically a cylindrical steel vessel with a capacity for storing a four- to eight-hour supply of fuel oil. Level controls ensure proper liquid level. For continuous level, the ECLIPSE Model 706 guided wave radar transmitter; the E3 MODULEVEL displacer transmitter; the PULSAR Model R86 radar transmitter; or the Model R82 transmitter are recommended. For point level, the Models A15 or B15 top-mounted displacer switches or the ECHOTEL Model 961/962 ultrasonic switch are recommended.
