摘要
针对水吸收法难于处理非(弱)水溶性有机废气的问题,以煤油为油相,失水山梨醇三油酸酯(Span-85)为乳化剂,制得水相/油相(W/O)乳化液膜,进行了吸收模拟乙酸乙酯废气的研究.结果表明:乳化液膜体系对乙酸乙酯废气吸收效率最高可达89%,1h内吸收效率大于50%以上;低温、低表面活性剂体积分数和高废气质量浓度有利于提高吸收速率,在实验条件下存在最佳油水比1∶1.
Considering that water absorption is difficult to treat insoluble VOCs, this paper used emulsion liquid membrane （ELM）, with kerosene as oil phase and Span-85 as emulsifier, as the advanced treatment agents to absorb simu- lated exhaust gas of acetic ether. The results showed that emulsiort liquid membrane system have the highest absorption efficiency for acetic ether by 89% , and the absorption efficiency could be more than 50% in one hour. Some factors, such as low temperature, low surfactant concentration and high exhaust gas concentration, are helpful to improve the absorption rate. There was an optimal oil-water ratio of 1 ： 1 under the condition of the experiments.
