Thermo-chemical dehydration technology for the crude oil of North Shaanxi oil fields

Zhang Mou

Abstract

Thermo chemical dehydration of the crude oil of North Shaanxi oil fields is tested by different demulsifiers. The performance properties of the demulsifiers are compared. Excellent demulsifiers for the crude oil are selected out. It is found that the dehydrating efficiency of some demulsifiers used in the district is lower,which would be replaced by other demulsifiers whose dehydrating efficiency is higher in the district.
