摘要
利用中海油湛江分公司生产的绥中减二线环烷基馏分油制润滑油基础油,针对该油酸值大、密度大、黏度大的特点,采用氨醇脱酸工艺对其脱酸精制,静态实验确定最佳萃取反应条件为:油温为60℃,剂油体积比为2∶1,氨水质量分数为5%;在最佳条件下,调节泵转数比(即流量比)为1∶1,对减二线馏分油进行二段动态脱酸,脱酸后原料油酸值低于0.05 mg(KOH)/g,达到润滑油基础油标准,溶剂回收率达94.67%,制得粗环烷酸酸值为79.475 mg(KOH)/g。
Lubricant base oil is prepared by using Suizhong crude oil from second-line naphthenic base reduction distillate of CNOOC Zhanjiang branch. Ammonia-alcohol deacidification method is used to reduce its acid value,density and viscosity. The optimal conditions determined by static test are 60℃ of oil temperature,2∶ 1 of agent / oil ratio and 5%mass fraction of ammonia concentratio. Under the optimal condition,the oleic acid value is less than 0. 05 mg（ KOH） / g after dynamic deacidification of second-line distillate with 1∶ 1 of flow ratio,which meet the lubricant base oil standards.The solvent recovery rate achieves 94. 67% and the resultant crude naphthenic acid value is 79. 475 mg（ KOH） / g.
