Title:
MIXED GAS SEPARATION DEVICE, MIXED GAS SEPARATION METHOD, AND MEMBRANE REACTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/153057
Kind Code:
A1
Abstract:
Each of a plurality of first cells (111a) opens at opposite ends in the longitudinal direction, and is provided with a separation membrane (12) on its inner side surface. A second cell (111b) closes at opposite ends in the longitudinal direction. A support body (11) is further provided with a slit (117) extending from an outer side surface (112) of the support body (11) to the second cell (111b). Mixed gas is supplied to one end surface (114) of a separation membrane complex (1) in the longitudinal direction. Sweep gas is supplied to the slit (117) opening to the outer side surface 112 of the support body (11). If the sum of cross-sectional areas of all the first cells (111a) vertical to the longitudinal direction is A, the sum of cross-sectional areas of all the second cells (111b) vertical to the longitudinal direction is B, and the sum of opening areas, on the outer side surface (112) of the support body (11), of all the slits (117) at one end in the longitudinal direction is C, then A/C is 1 to 50 inclusive, and B/C is 0.5 to 20 inclusive. Consequently, it is possible to improve the separation performance of mixed gas in a separation device (2).
