摘要
挑选4种具有潜在形成微乳液体系能力的助表面活性剂(1,2-丙二醇、己二醇、二甲基乙酰胺和N-甲基吡咯烷酮)作为废气吸收液,在设定的实验条件下对吹脱产生的2种模拟废气(甲苯、二甲苯)进行吸收研究。实验结果表明,4种吸收液中N-甲基吡咯烷酮对甲苯和二甲苯废气吸收效果最好,最高吸收率可达95%以上,并且2种VOC废气中二甲苯比甲苯吸收效果更好。
Four kinds of co-surfactants which have the potential to form the microemulsion system are selected as absorption liquid, including 1,2-propylene glycol, hexanediol, dimethyl acetamide and N-methyl pyrrolidone. The absorption of 2 simulated waste gas （toluene and xylene ） generated from air stripping under setting experimental conditions is performed. The results indicate that N-methyl pyrrolidone has the best absorption of toluene and xylene waste gas. The absorptivity can be above 95%. And the absorption of xylene is better than toluene. It can provide theoretical reference for the selection of co-surfactant in microemulsion absorption liquid.
