摘要: 用大庆尼罗混合减三线脱蜡油为原料,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2~3块。剂油体积比为6∶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酸值均小于0.03mgKOH/g,收率分别为64.53%与75.33%。具有4块理论板数的中试装置在剂油体积比为2.81∶1条件下得到的精制油酸值为0.0246mgKOH/g,收率为78.01%。精制油产品质量能够满足HVI400SN润滑油基础油的质量要求。

Abstract: Furfural refining towards the third vacuum dewaxed distillate refined from the mixed oil of Daqing and Nile was investigated. Calibration of theoretical plates number in the extraction column,multi-stage static extraction and pilot plant experiment were carried out. The results show that theoretical plates number in the column is 2 to 3. Under simulate-two-stage extractions,acid value of refined oil is below 0.03mgKOH/g when the value of volume ratio of solvent to oil (S/O) is 6. The acid value of refined oil meets the standard under simulate-four-stage extractions when the S/O is 3.2. The yields of refined oil are 64.53% and 75.33% respectively. Besides,acid value of the refined oil is 0.0246mgKOH/g in the pilot plant with four theoretical plates when the S/O is 2.81,and the yield of refined oil is 78.01%. The lubricating base oil meets the quality specification of HVI400SN.
