加氢裂化尾油作润滑油加氢原料的工业应用

为合理充分地利用现有资源，中国石化高桥分公司润滑油加氢装置采用VGO掺炼加氢裂化尾油、加工纯加氢裂化尾油以及加氢裂化尾油减压分馏后的塔底油直接进异构脱蜡单元的方法，增加了润滑油加氢原料的来源，改善了润滑油加氢原料的质量。本课题重点对加氢裂化尾油作润滑油加氢原料的工业应用情况进行跟踪分析，考察加氢裂化尾油作润滑油加氢原料时润滑油加氢装置的生产情况。结果表明，掺炼加氢裂化尾油或加工纯加氢裂化尾油可以生产多种高档润滑油加氢基础油。

INDUSTRIAL APPLICATION OF HYDROCRACKED TAIL OIL AS FEEDSTOCK FOR LUBRICATING OIL HYDROGENATION

For the rational use of existing resources,increase the feed sources for lube oil hydrogenation and improve the quality of lube oil feedstock,hydrocracked tail oil is used as lube oil feedstock at the lube oil hydrogenation unit of SINOPEC Shanghai Gaoqiao Branch in the following ways:hydrocracked tail oil blended with VGO,single hydrocracked tail oil and directly processing hydrocracked tail oil after vacuum distillation into iso-dewaxing unit.This paper focuses on the tracking analysis of these industrial applications.Results show that using hydrocracked tail oil as lube oil feedstock in either way,various high quality hydrogenated lube base oils can be produced.
