Study on absorption of simulated toluene-containing exhaust gas with emulsion liquid membrane(乳化液膜法处理模拟甲苯废气实验研究)
使用以煤油为油相, Span-85为表面活性剂制取的乳化液吸收甲苯废气,考察了表面活性剂浓度、进口甲苯气体浓度及喷淋液气比对吸收效率的影响,实验在填料塔中进行.结果表明,表面活性剂浓度小于2%时,表面活性剂对吸收效果影响较小,而大于2%时,随着浓度的增大吸收效率有明显的减小；进口甲苯浓度在300~900 mg • m-3的范围内,吸收效率随着甲苯浓度的提高而提高；喷淋液气比在3.0~5.0 L • m-3范围内,吸收效率随着液气比的增大而提高.在选择合适的乳化液及喷淋液气比基础上,处理浓度为300~900 mg • m-3低浓度甲苯废气,吸收效率可达85%以上....
