常压二线馏分油微波脱酸新方法研究

A new deacid refined method of distillate oil, microwave irradiation, was put forward. The optimum conditions of the refined process are investigated. The volume ratio of solvent to oil is (0.20～0.25)∶1, the pressure is0.04 MPa～0.06 MPa, the radiant time is 6 min under the constant pressure, microwave power is 375W, settled for 25 min the acidity will be reduced from 170.4 mg/100 mL to 8.35 mg/100 mL, which is good enough to meet the best specification of GB, and the refined process has no effect on the quality of the distillate oil. The oil used in this study is common cut 2 distillate from Liaohe oil field. The recovery ratio can reach 99.3%.
