USING DEMULSIFIERS FOR PHASE BREAKING OF WATER/OIL EMULSION

Amir Mosayebi, Reza Abedini

Open publisher page 17 citations

Abstract

Demulsification (emulsion breaking) is necessary in many practical applications as the petroleum industry and waste water treatment in environmental technology. The emulsion stability results from the presence of interfacial barrier preventing coalescence of the dispersed water droplets. The most effective method to overcome the problem is to demulsify the crude by using demulsifiers. The demulsifiers will destabilize the interfacial film between the droplets. Demulsifiers with amine and polymeric groups were used for breaking of water in crude oil emulsion, in this study. The relative rate of water separation were determined via breaker tests. The polymeric group demulsifier had better performance on breaking emulsion than amine group demulsifiers.
