This paper introduces the principle of oil separators,and gives the analysis of its working efficiency, then points out the study method of experimentation about the efficiency of oil separators.

Numerical Simulations on the Helical Pipe Oil-Water Separators for De-Oiling;

The principles and structure characteristics of the common oil-water separator are introduced.

Researching on the process mechanism of mass-transfer of coalescence-plate oil-water separator, a (novel) high efficiency composite coalescence-plate that can enhance the separating process was developed.

The revamp of internal construction of oil water separator in atmospheric-vacuum distillation unit from first generation to the third generation is detailed.

A vertical oil water separator,filled with a newly surface nature changed fiber,was designed to treat oily wastewater.

Gas carrying with wash oil after the benzol washer,disease of wash oil,leaking oil of oil water separator etc.

Study and application of new oil-gas separator for electric submersible pump;

Application of CFD in the modification of an oil-gas separator design;

It is one of the important part of the down hole oil-gas separator study to studying the sport analysis of oil-gas two fluid by applying the experiment method.
