摘　　要：针对中国石化荆门分公司生产的120BS光亮油在低于5℃的环境下存储一定时间后出现絮状物的情况,对絮状物的成因及解决方案进行攻关。在实验室分析絮状物的组成结构,对不同加氢改质条件的含蜡基础油进行脱蜡试验,并在工业装置上进行了防止光亮油出现絮状物的生产实践。结果表明:光亮油中出现的絮状物为正构烷烃、支化度低的链烷烃和带长侧链的环烷烃等高凝点组分;通过优化原油比例、控制丙烷脱沥青、糠醛精制和加氢改质各生产环节工艺条件,可为酮苯脱蜡装置提供优质原料;在原料性质稳定的前提下,酮苯脱蜡装置采取严格控制滤机温洗操作、降低溶剂水含量、控制好冷却速率、优化工艺条件等措施可以生产出没有絮状物、质量符合中国石油化工股份有限公司120BS光亮油标准要求的APIⅡ类基础油。The floccules in 120BS bright stock produced in SINOPEC Jingmen Company occurred during storage in an environment below 5 ℃. To solve this problem, the analysis of floccules structure and dewaxing test of the hydrotreated bright stock were made in lab and industrial trial practice was con- ducted. The results indicate that the floccules consist of high solidification point hydrocarbons, like long chain paraffin, less branched alkanes and long side chain naphthene and that the good and stable quali- fied feed for acetone-benzol dewaxing can be obtained by optimization of crude oil composition, operation conditions of propane deasphalting, furfural extraction and hydrotreating, and the 120BS bright oil without the floecules can then be produced by carefully controlling the operation conditions of each step in acetone-benzol dewaxing process. The 120BS complies with the standard of API Ⅱ and SINOPEC.
