PROBLEM TO BE SOLVED: To provide a spiral type module for acid gas separation: which is produced by winding around a laminate including an acid gas separation layer having a facilitated transport membrane; which has no defects in the facilitated transport membrane; and which has high quality.SOLUTION: A problem is solved by that a spiral type module for acid gas separation has: a supply gas flow path member which is a flow path for the raw material gas; an acid gas separating layer having, on the surface of the supply gas flow path member side, a carrier that separates the acid gas from the material gas flowing through the supply gas flow path member and reacts with the acid gas, and a facilitated transport membrane containing hydrophilic compound for supporting the carrier; a permeation gas flow path member which is a flow path where the acid gas that permeates through the facilitated transport membrane flows to a center cylinder; and at least one of a fluorine-based coating and a silicon-based coating formed on the surface of the facilitated transport membrane side of the supply gas flow path member. |
