METHOD OF SEPARATION OF GASES IN MEMBRANE APPARATUS Russian patent published in 2003 - IPC

FIELD: chemical, gas, food-processing, medical and other industries. SUBSTANCE: method includes delivery of gas mixture to be separated to flat membrane members having central hole; shears of said membrane members are matched with collector channel connected with one of outlet branch pipes; pressure in collector is kept below as compared with pressure of gas flow in inlet passage. Geometric form of flat membrane members does not coincide with form of cross section of inner surface of apparatus; membrane members form helical passage between their edges and inner surface of apparatus. EFFECT: enhanced efficiency of separation. 3 cl
