     Abstract

     Crude oil extracted from wells is often mixed with salt and water and forms a stable emulsion. Breaking this emulsion and removing water and salt from crude oil, is the first process. Addition of heat and electricity, chemicals are used to break the emulsion of crude oil. Demulsifiers plays a major role in breaking crude oil emulsion. There are several types of polymeric surfactants are presented as demulsifier.Two research team ACECR Tehran branch is doing a research project about demulsifier for the National Iranian Oil Company (NIOC). One of these demulsifiers are polyester amides that have been studied in some recent research in the world. In this paper, a class of this type of demulsifiers synthesized and products are evaluated in terms of performance. Preparation methods and results of performance evaluation methods for these materials are presented in this paper.   Finally, the discussion and conclusions, some suggestions for future approaches to these compounds is presented.
