| 摘 要： | 针对某炼化企业在石油储运过程中产生的罐底油泥,进行了油泥样分析和不同萃取剂萃取回收油分实验.经分析该罐底油泥含水率约16.1％,总有机物含量约34.8％,其中可萃取石油类物质约占总有机物成分的67.0％.考察不同溶剂的萃取效果,结果表明,石脑油90 ～ 110℃沸程段的馏分油的萃取效果和工艺可操作性优越于其他常用溶剂,其萃取效果排序为石脑油90～ 110℃沸程段的馏分油＞120#溶剂油＞正庚烷＞石油醚(90 ～ 120℃)＞石油醚(60 ～ 90℃);用石脑油90 ～ 110℃沸程段的馏分油在优化萃取工艺条件下,经两次萃取可分离出大于96％的可萃取油分,罐底油泥中有机物的萃出率可达64％以上,比120#溶剂油萃取效果高出约3％～5％,实现了罐底油泥更深程度的萃取和资源化利用.
