Abstract:

Gravity oil water separation is a kind of physical method for separating oil fromwater. Compared with oth-er separation methods, this process has several advantages, such as power free, running cost low, maintenance sim-ple, popularization easy, recycle available, etc. The basic principle and characteristics of the gravity oil water sepa-ration are introduced emphatically. The development of its technique and equipment is expatiated. Furthermore, its development direction is discussed.

Key words: gravity, oil water separation, coalescence
