摘要
To provide a CO 2 membrane separation and recovery system that is excellent in CO 2 permeability and CO 2 separation selectivity on recovery of CO 2 in a hydrogen production process and the like. The CO 2 membrane separation and recovery system of the present invention comprises a dehydration treatment module (2) preliminary to a CO 2 membrane separation module (1), the CO 2 membrane separation module (1) comprises a hydrophilic zeolite membrane (3) that exhibits CO 2 selective permeability and is formed on a porous substrate, and the hydrophilic zeolite membrane (3) is subjected to a dehydration treatment by a heat treatment at from 100 to 800°C.
