| 摘 要： | 用萃取法对某炼油厂减二线、减三线脱蜡油进行了脱氮精制处理的小试、中试系统实验。主要介绍了对减三线脱蜡油的中试实验，结果表明：糠醛助剂能有效地脱除脱蜡油中的碱性氮化物，精制油碱氮含量在10μg/g左右，其脱碱氮率高达97.6%；旋转氧弹时间为211min，黏度指数为112。确定减三线脱蜡油糠醛精制工艺中试的最佳操作条件为：抽提塔顶温115℃，底温67℃，剂油体积比2.0，助剂加入量8g/kg。可省去后面的白土补充精制。

| Abstract: | Using a third vacuum side dewaxed oil as feed,the pilot plant test of furfural extraction denitrogenation with assistant(metallic salt)added was introduced in this paper.Results showed that adding assistant in the furfural denitrogenation process could enhance the removal of basic nitrogen compounds in dewaxed oil significantly;the removal rate reached 97.6%.Under the optimum operation conditions of an extractor top temperature of 115℃,an extractor bottom temperature of 67℃,a solvent/oil volume ratio of 2.0 and an assistant adding amount of 8 g/kg(oil),the treated oil had a basic nitrogen content of 10.47μg/g,its viscous index was 112 and its rotating bomb oxidation test time reached 211 min. |
