含油污泥主要产生于油田或炼油厂，对环境造成污染，部分油资源浪费。目前国内外局限于对石油油泥处理，但对页岩油泥处理少有报道，为了解决这一问题，本文提出用热化学法处理页岩油泥。本文以汪清炼油厂油泥为样品，采用热化学法清洗页岩油泥，回收页岩油，并获取最佳清洗工况参数。纯水清洗页岩油泥，考察温度、搅拌时间、搅拌频率、液固比对清洗效率的影响，并确定初始工况参数。通过化学药剂筛选、复配，确定AEO-9∶Na2SiO3=1∶2为最佳清洗剂配方。正交试验确定最佳清洗工况参数。试验分析表明，当清洗温度为75℃、液固比为8∶1、搅拌频率220r/min、搅拌时间30min、药剂投加量为4.0g/L时，含油率为45.26%样品油泥经热化学法清洗后，油泥残油率降为3.03%。清洗液可循环利用，分离出的页岩油经处理后可回收利用，将清洗后的油泥残渣与固硫剂、页岩粉尘等混合后压碇成型，经干燥，进行低温干馏生产，从而实现页岩油泥的资源化、无害化、减量化。

Oil sludge is mainly produced in the oil fields and refineries,causing environment pollution,and wasting some oil resources. Recent research on oil sludge cleaning was limited to oil sludge treatment,with little focus on oil shale sludge treatment. This paper presented thermo chemical method to treat oil shale sludge. Oil shale sludge from Wangqing Oil Refinery was used as the sample. Washing media for oil shale sludge treatment was pure water. The study investigated the influencing factors including temperature,agitate time,agitate rate,liquid-solid ratio on the washing efficiency, and the initial conditions were determined. After screening and remixing,AEO-9∶Na2SiO3=1∶2(the mass ratio)was regarded as the optimal ratio. Orthogonal experiments were conducted to determine optimal washing parameters. The results showed that residual oil rate was reduced to 3.03% from 45.26%in the sample after agitating for 30 min at 75℃ with agitation speed at 220 r/min,liquid-solid ratio at 8∶1,chemical reagent concentration at 4.0g/L. Chemical reagent solvents can be recycled,oil recovery can be used after treatment. After mixing,the residual oil sludge was treated with sulfur-fixing agent and shale dust,then the mixture was molded and dried. The final products can be sent to retort for low temperature retorting.
