【摘要】:含油污泥是严重影响油田生产环境的一大危险废物,不仅含有大量原油资源,且处理难度大。本文针对吉林油田含油污泥,筛选几种有利于油、水和泥分离的药剂进行复配,通过正交实验确定OP-10(D)∶SDS(B)∶PAC(G)=2∶3∶3的最佳清洗剂配比,运用热化学清洗法从含油污泥中回收原油。利用单因素实验法分别考察了热洗温度、液固比、搅拌强度、搅拌时间、热洗次数及pH值单一因素对样品含油污泥清洗效果的影响。实验结果表明,最佳工艺条件为:选取热洗温度80℃,液固比为4∶1,药剂量为1%,搅拌强度为120 r·min-1,搅拌时间为30 min,pH为8,热洗后的清洗废液经处理调整至初次清洗浓度可循环利用。在最佳工况下,将含油率为51.13%的污泥样品洗至脱油率为96.75%,较好的回收了污泥中的原油,达到了保护环境的目的,具有经济价值。
[Abstract]:Oily sludge is a major hazardous waste which seriously affects the production environment of oil fields. It not only contains a lot of crude oil resources, but also is difficult to deal with. In this paper, for oily sludge in Jilin Oilfield, several kinds of chemicals which are favorable to separating oil, water and mud are selected and the optimum ratio of cleaning agent of OP-10 (D): SDS (B): PAC (G) 2: 3: 3 is determined by orthogonal experiment. Crude oil was recovered from oily sludge by thermochemical cleaning. The effects of heat washing temperature, liquid-solid ratio, stirring intensity, stirring time, heat washing times and pH value on the cleaning effect of oily sludge were investigated by single factor experiment. The experimental results show that the optimum technological conditions are as follows: the hot washing temperature is 80 鈩,
