摘要
采用自主研发的萃取剂ZYHM对胜利油田含聚油泥进行处理。实验研究了剂泥质量比、萃取温度、搅拌速度、搅拌时间、萃取级数对除油率的影响以及萃取剂的回收效率,确定了最佳工艺条件,即在室温、剂泥质量比为3∶1、160r/min的转速下搅拌30min,除油率可达93.6%,底泥含油率可降至0.66%。萃取剂通过减压蒸馏回收,回收率可达97%,循环使用6次后的萃取剂除油率仍可达到90%。与传统萃取剂相比,萃取剂ZYHM具有成本降低30%、去除效率高、循环使用效果好的优势。
The polymer-containing oily sludge from Dongying Shengli oilfield was treated by the self-developed extractant ZYHM.The optimum technological conditions were determined by studying the effects of agent-mud ratio,extraction temperature,stirring speed,stirring time and extraction degree on the oil removal efficiency and recovery efficiency of extractant.At the conditions of room temperature,the ratio of extractant and sludge is 3∶1,30 min stirring time at 160 r/min rotational speed,the oil removal rate can reach 93.6%,and the oil concentration of sludge is decreased to 0.66%.The extractant ZYHM can be recovered by vacuum distillation,and the recovery rate is 97%.After 6 times of recycling,the oil removal rate of the extractant ZYHM can still reach 90%.Compared with the traditional extractant,the cost of extractant ZYHM is reduced by 30%,and it has higher removal efficiency and better recycling effect.
