高酸原油脱钙技术进展

Development of Decalcification for High-acid Value Crude Oil

介绍了高酸原油酸值与钙含量之间的关联和钙在原油中的赋存状态、危害。综合国内外原油脱钙方法及应用背景,指出当前脱钙技术及脱钙剂存在的不足;针对现有的高酸值高钙原油的特点,提出螯合、沉淀脱钙法有较好的应用前景,提出研制开发新型、高效、环境友好、廉价的脱钙剂是主要的发展方向。

The relationship between high acid - value and high calcium content, state of calcium, harm of calcium in the crude oil were introduced. Through analyzing the method and development of removal of non -water soluble organic calcium salt from high salt content crude oil in domestic and abroad, the disadvantages of current decalcifying technology were indicated. According to the characteristic of high acid - value and high calcium content of crude oil, it was proposed that chelation deposition of decalcifying had a better application prospects and a kind of new decalcification which was highly efficient, environment friendly and cheap was the main direction of the development.
