摘　　要：随着石油重质化、劣质化趋势的日益加剧,石油中的腐蚀性介质给加工装置带来的腐蚀和安全问题逐渐突出,其中由氯引起的腐蚀已由常减压蒸馏装置扩展到二次加工装置。为明确石油中氯化物腐蚀的特性和原理,以便采取相应的防腐蚀措施,系统介绍了石油中氯化物的类型、来源及分布,概述了不同类型氯化物的检测分析方法,探讨了不同类型氯化物在石油加工过程中的转化机理。As the crude oil became heavier and inferior,the corrosion and safety issues of the processing units caused by corrosive media in petroleum became prominent gradually.Among them,the corrosion problems caused by chlorides extended from atmospheric and vacuum distillation units to secondary processing units.To clarify the characteristics and fundamental principles of chloride corrosion in the oil,so that corresponding anti-corrosion measures could be taken,the types,sources,and distribution of chlorides in the oil were systematically introduced,the detection and analytical methods for different types of chlorides were summarized,and the transformation mechanisms of different chlorides during processing were discussed.
