摘要: 以克拉玛依稠油减四线馏分油为原料,在200 kg/h微反应器上进行脱酸新工艺中试试验研究。试验结果表明:与同时运行的工业装置相比,微反应器脱酸工艺一级脱酸率大于85%,高于工业装置两级脱酸效果,该工艺能够大幅度降低剂油比,降低装置回收溶剂能耗,而且简化了脱酸工艺,为从重质原油馏分油中抽出大分子石油酸提供一项新技术。

Abstract: Pilot plant tests of removing naphthenic acid from the 4th vacuum side cut of Karamay heavy crud were carried out on a 200 kg/h microchannel reactor. Test results showed that the acid removal rate of this single stage microreactor process was more than 85%, which was better than that of the industrial two-stage extraction process with the same feedstock. Besides, this new process simplified the acid removal process, its solvent to oil ratio and energy consumption were much lower. It offers a new choice to remove large naphthenic acid molecules from heavy crude fractions effectively.

Key words: microreactor, asid removal, pilot plant test
