Multi-stage membrane systems are arranged so that, with the same number of modules and compressors, mixing losses upon combining recycle and feed streams are minimized. Membrane surface area and power requirements are reduced thereby.
An improved membrane process for the production at high or very high purity, of a less selectively permeable component of a feed gas containing said component and a more selectively permeable component, comprising: (a) introducing the feed gas at a feed pressure to a first stage membrane module of a membrane system containing a total of at least three membrane module stages, said system being capable of selectively permeating the more selectively permeable component thereof; (b) separately removing the less selectively permeable component from the first ...
