Title:
METHOD AND APPARATUS FOR PRODUCING ACIDIC GAS SEPARATION MEMBRANE SHEET
Document Type and Number:
WIPO Patent Application WO/2019/097995
Kind Code:
A1
Abstract:
This method for producing an acidic gas separation membrane sheet comprises: a step (S1) for preparing a hydrophilic resin composition liquid for forming a hydrophilic resin composition layer; a step (S2) for removing air bubbles from the hydrophilic resin composition liquid; a step (S3) for forming a coating layer on a first porous layer by applying the hydrophilic resin composition liquid onto the first porous layer; and a step (S4) for forming a laminate by superposing a second porous layer on the coating layer. The step (S2) for removing air bubbles includes a step (S2a) for applying a shear to the hydrophilic resin composition liquid and a step (S2b) for leaving the hydrophilic resin composition liquid at rest.
