FIELD: process engineering. ^ SUBSTANCE: invention relates to separation of gas mixes by means of semi-permeable membranes and may be used in gas, oil, chemical industries, etc. Proposed method comprises feeding gas mix into membrane gas separation unit. Flow of gas not penetrated into membrane unit is directed to consuming equipment. Flow of gas penetrated in membrane unit is directed for other needs. Flow of gas not penetrated into membrane unit is restricted and directed into membrane unit for blowing penetrated gas flow. Pressure of both penetrated and not penetrated gals flows is reduced to below atmospheric pressure by means of vacuum compressors and compressed for direction into either storage or forcing into natural formation, or for further processing. ^ EFFECT: higher degree of extraction, lower power consumption. ^ 6 cl, 4 ex |
