摘　　要：以大连石化公司减三线脱蜡油为原料油,在小试的基础上进行了糠醛精致的中试实验研究。结果表明,改造抽提塔理论板数不少于4块,同时对改造后的装置操作条件进行优化。优化后的操作条件:塔顶温度117℃,塔底温度68℃,剂油体积比2.81∶1。在此条件下,精制油的黏度指数达到105,收率78.01%,酸值为0.024 6 mg/g。满足HVI400SN润滑油基础油质量要求。With the No.3 line vacuum fraction dewaxed oil from Dalian ShiHua company as feedstock,the pilot study of furfural refining is carried out based on the small trial.The results show that the number of theoretical plates for the improved pumping stripper is no less than 4.The operation parameters for the modified devise are optimized.The optimal conditions are shown as follows：2.81 ∶ 1 volumetric ratio of solvent to oil,117℃ of pumping stripper top temperature and 68℃ of the bottom temperature.Under the optimal conditions,the refined oil viscosity index can reach 105,the yield and acid value are 78.01％ and 0.024 6 mg （KOH）g-1,respectively,which can meet the quality requirements of HVI400SN lubricant base oil.
