摘要

According to the composing characteristics of the high-acid crude oil and on the basis of validating traditional distillate acid removal technique by test, the chemical acid removal is the development direction of the acid removal for high-acid crude oil. A series of acid removal agents are successfully developed by the chemical theory and they are the same with the crude oil with different qualities such as high freezing point and high viscosity oil , ordinary heavy oil, and extra-heavy oil. The corollary technologies of the acid removal for crude oil are completed and they include recycle and repetition use of the naphthenic acid and recycle and repetition use of the acid removal agents, and so on. The integrated new acid removal technique for crude oil is formed. The on-site operational process of the technique is simple and it can cooperate with the dehydration and salt removal technique for crude oil. It doesn't need to greatly reform existing technique. The middle-tests of Block 6 in Sudan show that the TAN (Total Acid Number) declines from 10mgKOH/g to less than 0.5 mg KOH/g after two grade acid removal treating; After the first crude oil treating of Block 3&7 is done, the TAN can decline from 5 mgKOH/g to 0. 5 mg KOH/g; After the second crude oil treating of super-heavy oil in Li-aohe, the TAN may decline from 10 mg KOH/g to less than 3 mg KOH/g. According to the middle-test, the operation parameters of different crude oil and different operation process are determined.
