These presentations provide an understanding of two-phase and three-phase separators, describe how they work and what the design procedures are for sizing them. Then, different methods and procedures are described for oil treating and associated equipment design. Oil desalting is the process of removing water-soluble salts from an oil stream. This presentation describes the equipment commonly used and provides references for sizing the equipment. Crude oil or condensate stabilization describes the various processes used to stabilize a crude oil or condensate stream, and presents a preliminary method for determining liquid recoveries through stabilization.
