Correlation Between Surface Film Pressure and Stability of Emulsion

Abstract

A new approach for the determination of stability of crude oil emulsion is described. A strong correlation has been established between surface film pressure and stability of emulsions. It has been shown that stability of emulsion is directly proportional to film pressure. It has been concluded that prior to demulsification, the study of physical characteristics of the film-forming material can be very useful in selection of suitable demulsifiers in resolving oil field emulsions in petroleum industries.
