膜分离技术在天然气净化中的应用现状

Application Status Quo of Membrane Seperating Technique on Natural Gas Purifying

本文综述了80年代以来,国外利用膜分离技术处理天然气的应用现状。目前该技术主要用于分离天然气中的CO_2,已有些用于了分离天然气中的H_2S,特别是用于分离含H_2S较高的天然气并获得满意效果,为含酸气浓度高的天然气处理提供了一种可行的方法。

In this paper, status quo of membrane seperating technique abroad applicated to treat natual gas is summarized. At present, membrane seperating technique is mainly used to seperate CO_2. Sometimes it has been used to seperate H_2S, especially to seperate high concentration H_2S from natural gas and the satisfactory results can be obtained, which offers a practical method to treat high concentration acidic gas.
