PROBLEM TO BE SOLVED: To provide an acidic gas separation module which comprises a facilitated transport membrane including an acidic gas carrier reacting with the acidic gas in the presence of water and has high separation performance.SOLUTION: An acidic gas separation module 10 has a laminated body 14 obtained by laminating a supply gas flow channel member 30 through which a raw material gas 20 including at least an acidic gas and moisture is supplied, a facilitated transport membrane including an acidic gas carrier reacting with the acidic gas in the raw material gas 20 supplied to the member 30 in the presence of water, and a member 36 for a permeation gas flow channel through which the acidic gas reacting with the acidic gas carrier to permeate the facilitated transport membrane flows. The module is obtained by winding the laminated body 14 on a permeation gas-collecting tube 12, on the wall of which the through-holes 12A are formed. The member 36 for the permeation gas flow channel has a plurality of grooves 36R on the face of at least a side of the facilitated transport membrane, and the angle &thetas; between the grooves 36R and the central axis of the collecting tube 12 is 0° or more to 75° or less. |
