摘　　要：利用硅橡胶（ Ｌ Ｔ Ｖ）／ 聚醚酰亚胺（ Ｐ Ｅ Ｉ） 复合膜做成的卷式膜分离器，进行了有机蒸气（ Ｖ Ｏ Ｃ）／ 氮气混合气分离过程的研究，主要考察了原料气的处理量、浓度、压力以及渗透侧真空度对有机蒸气脱除率的影响．实验结果表明，当压力为０ ．６ Ｍ Ｐａ ，处理量为１ ．０３ ｍ ３／ｈ ，渗透侧真空度为０ ．０２ Ｍ Ｐａ 时，有机蒸气的脱除率达到９０ ％ 以上；提高原料气侧的压力以及在渗透侧抽真空。The experiments of separation of vapor organic component (VOC)/nitrogen (N 2) by spiral membranes model have been done. The membrane is a composite membrane which consists of a silicone rubber (LTV)/poly (ether mide) (PEI). The influence of feed vapor concentration, feed pressure, feed flow and vacuum on the permeate side ect. on separation of VOC/N 2 has been tested. The results showed that with increase feed pressure and vacuum on permeate side separation increased, separation VOC/N 2 can reached about 90%, when feed flow, pressure and vacuum was 1.03?m 3/h,0.6?MPa, 0.02?MPa.
