Abstract: Solvent refining on the second vacuum dewaxed distillate refined from the mixed oil of Daqing and Weizhou using furfural was investigated. Calibration on theoretical plate number in the extraction column, multistage static extraction and pilot plant experiment were carried out in turns. The results show that theoretical plate number in the column is two. Viscosity index of refined oil is 100 under both simulatetwostage extractions when the value of volume ratio of solvent to oil (S/O) was 5.47∶1 and simulatefourstage extractions when the S/O was 3.2∶1, and the yield of refined oil is 64.07% and 66.01% respectively. Besides, viscosity index of the refined oil is 101 in the pilot plant with four theoretical plates when the S/O was 327∶1, and the yield of refined oil is 70.5%. The lubricating base oil meets the quality specification of HVI150SN.
