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，都可以使脱除率增加 The separation of organic vapor (V O C) / nitrogen gas mixture was investigated using a roll-to-roll membrane separator made of silicone rubber (L T V) / polyetherimide (P E I) The effects of feed gas volume, concentration, pressure and permeate side vacuum on organic vapor removal rate were investigated. Experimental results show that when the pressure is zero. 6 M Pa, throughput is 1. 03 m 3 / h, and the degree of permeation side vacuum is zero. 02 M Pa, organic vapor removal rate of 90% or more; increase the pressure on the raw material gas side and vacuum on the permeate side, can make the removal rate increased
