COMPLEX FOR ACID GAS SEPARATION, MODULE FOR ACID GAS SEPARATION, AND METHOD FOR MANUFACTURING MODULE FOR ACID GAS SEPARATION

[Objective] To provide a complex for acid gas separation that can suppress gas leaks and that has high separation performance and durability. [Composition] A complex for acid gas separation (1) includes an acid gas separation membrane (2), a permeated gas flow path member (5), and a sealing portion (3). The acid gas separation membrane (2) includes a porous support (2B) with pores having an average pore diameter of 0.5 µm or less, and an acid gas separation layer (2A) disposed on the porous support (2B), including water-absorbing polymers and acid gas carriers that react with acid gas in raw material gas. The permeated gas flow path member (5) allows acid gas, which has reacted with the acid gas carriers and has permeated through the acid gas separation layer (2A), to pass therethrough. The sealing portion (3) seals a region required to be sealed with resin, the region being on the periphery of the permeated gas flow path member (5) and the porous support (2B). The sealing portion (3) is made of epoxy resin, the Tg of epoxy resin is 90° C or higher and the content of an inorganic filling material is less than or equal to 30% by mass.
