摘　　要：炼油厂用于装卸和储存原油的油罐和容器中自然沉淀在下方的原油和其他物质的堆积就会形成罐底污泥,原油储罐中积聚的污泥和固体会减少储罐容积,需要定期清除和处理,继而产生大量的清罐污油,这部分原油无法直接作为下游装置的炼制原料。对清罐污油进行资源化回收,不仅需要满足装置运行指标,还要考虑降低废物的毒性和减少对环境的潜在影响。某炼油厂针对清罐污油采取一种预处理净化技术(Slop Oil Treatment Unit,SOTU),一定程度上解决了清罐污油处置难题,达到了经济、环保双效益。The accumulation of crude oil and other substances that naturally settle below in the tanks and containers used for loading,unloading and storage of crude oil in refineries results in the formation of tank-bottom sludge.The accumulation of sludge and solids in crude oil storage tanks reduces the volume of the tanks,which needs to be periodically removed and disposed,and subsequently produces a large amount of tank-cleaning oil,which is unable to be used directly as a feedstock for the refining of downstream units.Resource recovery of slop oil from tank cleaning not only needs to meet the operational targets of the plant,but also needs to consider reducing the toxicity of the waste and the potential impact on the environment.A refinery has adopted a pretreatment and purification technology(Slop Oil Treatment Unit,SOTU)for slop oil,which solves the problem of slop oil disposal to a certain extent and achieves both economic and environmental benefits.
