摘要: 中海油气(泰州)石化有限公司以绥中SZ36-1减三线馏分油为原料,通过高压加氢装置生产环烷基润滑油基础油(简称基础油),包括U30变压器油、N4010橡胶增塑剂等。针对该装置生产环烷基基础油的收率标定结果比设计值低的问题,分析了其影响因素,并相应采取提高原料油中润滑油组分比例、增大空速、降低脱蜡反应深度、控制产品指标等措施来提高环烷基基础油收率。结果显示:环烷基基础油的平均收率由改进前的83.67%提高至86.50%,提高2.83百分点;收率最高可达89%。

Abstract: The naphthenic base oil (U30 transformer oil, N4010 rubber plasticizer) was produced by a high-pressure hydrogenation unit in CNOOC Oil & Gas (Taizhou) Petrochemical Co., Ltd. Aiming at the problem that the calibration results of naphthenic base oil produced by the unit was lower than the designed value, the influence factors was analyzed. In order to improve the yield of naphthenic base oil, some measures was taken, such as increasing the lubricating oil composition of the feedstock, increasing the space velocity, reducing the depth of the dewaxing reaction, and controlling product indicators on their indicator boundaries. The results showed that the average yield of naphthenic base oil was increased from 83.67% to 86.50%, and the highest yield could reach 89%.
Key words: naphthenic, base oil, lubricating oil, high-pressure hydrogenation
