  • Membrane gas separation process with compressor interstage recycle
    Patent number: 6428606
    Abstract: A process for treating a gas stream containing an organic component and a second gas. The process uses at least two compression stages, followed by membrane separation, with recirculation of the membrane permeate streams to different points in the compression train. The process provides particular benefits for separations characterized by modest membrane selectivity and a high concentration of the organic component in the remaining gas the compression steps.
