摘　　要：原油中的无机氯化物主要以碱金属和碱土金属盐形式存在,利用电脱盐装置可以有效地脱除这些氯化物。有机氯化物来自采油过程中使用的含氯助剂,早期研究认为有机氯主要分布在原油轻馏分中,近年研究表明有机氯的分布较为复杂,在原油的重馏分中也含有较大量的氯化物,且现有的电脱盐装置并不能有效地脱除原油中的有机氯化物,因此需要开发新的脱除有机氯化物的方法。Inorganic chlorides in crude oil exist mainly in the forms of alkaline metals and alkaline-earth metal salts,and can be effectively removed by using electrostatic desalting units.Organic Chlorides are from chloride-containing additives used in oil production.It was believed by the research in the early stage that the organic chlorides were mainly distributed in the light distillates of the crude oil.The research in recent years show that the organic chlorides is quite complicate,the heavy distillates also contain large amount of chlorides,and the existing electrostatic desalting units can not effectively remove the organic chlorides from the crude oil,so new methods for organic chloride removal need to be developed.
