| 摘 要： | 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%,1 h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.

| Abstract: | 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 simulated exhaust gas of acetic ether.The results showed that emulsion 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 ex... |
