摘要 针对某炼化企业罐区混存轻质、重质和化学性质活泼的混合污油的情况,在延迟焦化装置加热炉系统进行了混合污油的回炼,通过工艺流程优化改造和投用后的效果分析,解决了混合污油较难处理的问题。回炼混合污油后,主要产品柴油收率升高2.59百分点,月平均增效228.07万元。本次延迟焦化装置污油回炼项目的实施,是重油装置处理轻油工艺流程上的一次探索性创新,对焦化装置加工乙烯焦油具有一定的借鉴意义。 In view of the mixed waste oil with light,heavy and active chemical properties in the tank farm of a refining and chemical enterprise,the mixed waste oil was reprocessed in the furnace system of the delayed coker.The difficult problem of treating mixed waste oil was solved by the optimizing the technological process and analyzing the effect after putting into use.The results showed that after refining the mixed waste oil the yield of diesel increased by 2.59 percentage points,and the monthly average efficiency increased by 2.2807×10^(6) Yuan.The implementation of the mixed wase oil refining project of delayed coker is an exploratory innovation in the light oil treatment process of heavy oil unit,which has certain reference significance for the processing of ethylene tar in coker.
