Abstract: The research progress of demulsification mechanism in recent years is reviewed.The types of demulsifier commonly used are introduced.The demulsification performance of different demulsifiers is discussed, including the target, the effective addition quantity, the number of recycling and the demulsification rate.Through the comparison of various demulsifier properties and the mechanism involved.Combining with the present research situation,it is discussed which demulsification mechanism is meaningful to the research of demulsifier in the future,and the future research direction of demulsifier is prospected.
