摘要
综述了从重质高酸值原油及其油品脱环烷酸的工艺研究。脱除环烷酸的方法一般可有化学萃取、溶剂萃取、吸收等。介绍了可能用于脱环烷酸的中和剂、破乳剂及表面活性剂。
Progress of the removal of naphthenic acid from heavy sour crude and its fraction is reviewed. Methods of the removal of naphthenic acid are chemical extraction, solvent extraction absorption, and so on. Some neutralization agents, demulsifiers and surface active agents are introduced.
