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

摘要

A complex for acid gas separation includes an acid gas separation membrane, a permeated gas flow path member, and a sealing portion. The acid gas separation membrane includes a porous support with pores having an average pore diameter of 0.5 μm or less, and an acid gas separation layer disposed on the porous support. The permeated gas flow path member allows acid gas, which has permeated through the acid gas separation layer, to pass therethrough. The sealing portion seals a region required to be sealed with resin, the region being on the periphery of the permeated gas flow path member and the porous support. The sealing portion 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.

1. A complex for acid gas separation, comprising:
an acid gas separation membrane including:
a porous support with pores having an average pore diameter of 0.5 μm or less; andan acid gas separation layer disposed on the porous support, the acid gas separation layer including water-absorbing polymers and acid gas carriers that react with acid gas in a raw material gas; a permeated gas flow path member that allows acid gas, which has reacted with the acid gas carriers and permeated through the acid gas separation layer, to pass therethrough; and a sealing portion that seals a region on the periphery of the permeated gas flow path member and the porous support with resin, the region being required to be sealed, wherein the resin is made of epoxy resin, the Tg of the resin of the sealing portion is 90° C. or higher, and the content of an inorganic filling material is less than or equal to 30% by mass.
