原油乳状液的稳定性研究与新型破乳剂研究进展

Research progress of the stability of the crude oil emulsion and new types of demulsifier

综述了原油乳状液中天然表面活性物质,如沥青质、胶质、石蜡晶、固体颗粒对原油乳状液稳定性的影响,并综述了相关因素影响机理的研究现状。针对原油乳状液现有的稳定情况,介绍了几种新型破乳剂的研究进展。

Research advance of the effect of natural surfactants on the stability of water-in-crude oil emulsion was summarized in this paper,the natural surfactants involve asphaltenes, resins, naphthalene and solid particles and so on. The research present situation of the factors concerned of emulsion-breaking mechanisms was analyzed also. Basing on the stability of water-in-crude oil, the research advance of several new types of demulsifies in water-incrude oil are presented.
