介绍了以聚醚嵌段酰胺(PEBA)膜材料制备出的分离膜在有机蒸气回收方面的应用。分别从材料的特点、分离膜的制备方法以及膜的分离性能等方面进行分析,表明PEBA这种新型膜材料在有机蒸气回收方面的优良性能。并对复合分离膜的底衬阻力对复合膜分离性能的影响进行了分析,最后对气体膜分离在有机蒸气回收中的应用进行展望。
The application of the separation membrane prepared with polyether block amide (PEBA) membrane material in organic vapor recovery is introduced. The characteristics of the material, the preparation of the separation membrane and the separation performance of the membrane were analyzed respectively, which showed that PEBA is a new type of membrane material with excellent performance in organic vapor recovery. The influence of the liner resistance of the composite separation membrane on the separation performance of the composite membrane was analyzed. Finally, the application of gas membrane separation in the recovery of organic vapor was prospected.
