1 前言通常气体混合物的分离、纯化和富集采用低温技术、吸收技术、吸附技术和催化技术。而现在还可使用膜分离系统。在过去的15年中已研制出分离气体混合物的膜分离方法,并得到广泛的认可,今天,许多气体混合物分离采用的薄膜分离流程正跃跃欲试替代传统的分离方法。薄膜分离技术应用的 1 Introduction Generally, the separation, purification and enrichment of gas mixtures are carried out using cryogenic technology, absorption technology, adsorption technology and catalytic technology. Now it is possible to use membrane separation systems. Membrane separation processes for the separation of gas mixtures have been developed over the past 15 years and are widely recognized. Today, many membrane separation processes used to separate gaseous mixtures are eager to replace the traditional separation methods. Application of membrane separation technology
