FIELD: separation of gas mixtures in chemical and gas industries. SUBSTANCE: initial gas mixture is delivered from one end of the apparatus roll, the permeate is unloaded from its other end and the non- permeate is discharged from the central collector. The invention enables the source mixture inlet passage to be increased to 20 sq. cm at a diameter of 90 mm and turbulator thickness of 0.55 mm. EFFECT: higher productivity and reliability of the roll-type apparatus. 3 dwg
