| 摘 要： | 大庆涠洲混合减二线脱蜡油为原料,先后进行了工业装置理论塔板数标定、多级静态及中试规模的糠醛溶剂精制实验研究。结果表明,工业装置理论塔板数为2块。剂油体积比为5.47∶1的假二段实验与剂油体积比为3.2∶1的假四段实验精制油的黏度指数均可达到100,收率分别为64.07%与66.01%。具有4块理论板数的中试装置在剂油体积比为3.27∶1条件下得到的精制油黏度指数为101,收率为70.5%。精制油产品质量能够满足HVI150SN润滑油基础油的质量要求。

| Abstract: | Solvent refining on the second vacuum dewaxed distillate refined from the mixe d 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. |
