Title:
ACIDIC GAS SEPARATION MODULE
Document Type and Number:
WIPO Patent Application WO/2016/121436
Kind Code:
A1
Abstract:
An acidic gas separation module which comprises: an acidic gas separation membrane that comprises a porous supporting body, a carrier diffusion suppression layer at least a part of which is formed within the porous supporting body, and a facilitated transport membrane which contains a hydrophilic compound and a carrier that is reactive with an acidic gas; and a member for supply gas channels, which serves as a channel for a starting material gas. The projected area ratio of the porous supporting body in the surface excluding the facilitated transport membrane is 50% or more, and the projected area ratio of the carrier diffusion suppression layer in a cross-section in the thickness direction of the porous supporting body is 30% or more. Consequently, the present invention provides an acidic gas separation module which exhibits excellent adhesion of a facilitated transport membrane, while having good durability.
