DESALTING PROCESS AND SYSTEM

摘要

A compact desalting system for use in a process of desalting crude oil comprises a plurality of separation stages. Each separation stage includes a compact electrostatic coalescer ( 42, 62 ) for coalescing water droplets carried with the crude oil and settling means ( 91, 92; 95, 96 ) for settling separated oil and coalesced water droplets. The system includes a vessel ( 46 ) comprising a plurality of compartments containing the settling means and the compact electrostatic coalescers are each mounted in a housing on top of the vessel.
