摘　　要：近年来,随着常规原油资源日益减少和原油开采技术的提高,非常规原油的产量逐年增加。非常规原油的酸值一般较高,基本都属于高酸原油,高酸原油在加工的过程中会对设备造成严重的腐蚀,而且对石油产品的使用性能产生较大影响,因此,解决高酸原油加工问题具有重大的意义。介绍了国内外高酸原油脱酸的几种工艺,如碱洗脱酸、醇氨法脱酸、酯化脱酸、加氢法、热分解法等方法,并对各种方法进行了对比。In recent years, with the decreasing of conventional crude oil resources and the improvement of crude oil developing technologies, unconventional crude oil production is increasing year by year. Generally, the acid number of unconventional crude oil is high. The crude oil with high acid number may cause serious corrosion to the processing equipment in the refining process. The acid number of crude oil will also impact the performance of oil products. Therefore, it is great significance to solve the processing problems of the crude oil with high acid number. In this paper, several deacidification technologies of high acid crude oil were introduced, such as alkaline wash deacidification, alcohol-ammonia deacidification, esterification deacidification, hydrogenation deacidification ,thermal decomposition deacidification and so on. At last, these oil deacidification technologies were analyzed and compared.
