DESALTING PROCESS

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.
