摘要
以克拉玛依稠油减四线馏分油为原料,在200kg/h微通道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,微反应器脱酸工艺的一级脱酸率大于85%,高于工业装置的两级脱酸效果;该工艺能够大幅度降低剂油比,降低装置回收溶剂的能耗,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了一项新技术。
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.
