摘要:
Provided is an acid gas separation membrane that includes an acid gas separation layer containing a hydrophilic resin and an acid gas carrier, a hydrophobic porous membrane layer supporting the acid gas separation layer, a porous membrane protective layer protecting the acid gas separation layer, and a first layer having a Gurley number of less than or equal to 0.5 times a Gurley number of the hydrophobic porous membrane layer and the porous membrane protective layer, the Gurley number of the first layer being greater than or equal to 0.1 s and less than or equal to 30 s. Also provided is an acid gas separation method using the acid gas separation membrane, as well as an acid gas separation module and an acid gas separation apparatus that each include the acid gas separation membrane.
