2003年7月15日,齐化集团PVC分厂采用膜法回收氯乙烯单体开车成功,并于近日正式投入生产使用。该装置是2003年上半年引进的,有机蒸汽膜法回收系统主要采用“反向”选择性高分子复合膜,在一定的渗透推动力作用下,根据不同气体分子在膜中的溶解扩散性质的差异,可凝性有机蒸汽氯乙烯 July 15, 2003, Qihua Group PVC plant using vinyl chloride monomer recovery method successfully, and recently put into production. The device is introduced in the first half of 2003, the organic vapor membrane recovery system mainly uses the “reverse” selective polymer composite membrane, under the action of a certain osmotic impetus, according to the diffusion properties of different gas molecules in the membrane Variations, condensable organic vapor vinyl chloride
