1. In many applications, this is rectified by coalescer / filter vessels. 2. It consists of two separator stages and the electrostatic coalescer . 3. Then, the air usually will pass through a water separator coalescer or the sock. 4. The coalescer at the top of the prewash entrained and carried out of the vessel. 5. The second-stage filter uses coalescer inserts to achieve the final de-oiling. 6. Normally the oil from the separator is routed to a coalescer to further reduce the water content. 7. Part of the process equipment on the FPSO is an electrostatic coalescer with the VIEC technology from Hamworthy. 8. By keeping the treatment and settling sections separate, a compact electrostatic coalescer can be obtained that can also be retrofitted. 9. An alternative to this type of coalescer is a flow through pre-coalescer that is installed upstream in a separator tank. 10. An alternative to this type of coalescer is a flow through pre-coalescer that is installed upstream in a separator tank.
