| 摘 要： | 针对某炼化企业在石油储运过程中产生的罐底油泥,进行了特性分析及萃取工艺优化实验.结果表明,该罐底油泥含水率约为16.1％,随着烘干时间的延长其脱水速率越来越低;当罐底油泥含水率为4％时,各溶剂的萃取效果均最佳,且溶剂萃取效果从优至劣的顺序为石脑油、120#溶剂油、正庚烷;以石脑油为溶剂时,适宜的萃取条件为：萃取温度50℃,萃取时间30 min,溶剂/罐底油泥（质量比）5,在此优化条件下,可萃油分萃出率大于62％.

| Abstract: | The characteristics analysis and solvent extraction process optimization were conducted for the tank bottom sludges formed during crude oil storage and transportation in a oil refining and chemical enterpise.The results showed that the mass fraction of water in the oily sludge was about 16.1％,and as the drying time extended,the dehydration rate of the sample got smaller and smaller.When the sludge was dried to 4％ of water mass fraction,every solvent had optimal extraction result,and the order of solvent extraction efficiency from good to poor was naphtha,120# solvent oil,n-heptane.The optimized extraction conditions for naphtha were temperature 50 ℃,time 30 min,solvent/sludge mass ratio 5,under which more than 62％ recoverable oil could be extracted. |
