摘要： A manufacturing method for an acidic gas separation membrane sheet includes: a step of preparing a hydrophilic resin composition liquid for forming a hydrophilic resin composition layer (S1); a step of removing bubbles contained in the hydrophilic resin composition liquid (S2); a step of applying the hydrophilic resin composition liquid onto a first porous layer to form an applied layer on the first porous layer (S3); and a step of laminating a second porous layer on the applied layer to form a laminated body (S4). The step of removing bubbles (S2) includes: a step of applying a shear to the hydrophilic resin composition liquid (S2a); and a step of leaving the hydrophilic resin composition liquid (S2b).

摘要： Provided are a spiral-wound gas separation membrane element, a manufacturing method therefor, a gas separation membrane module and a gas separation apparatus that include the element. The element includes a laminated body wound around a perforated central tube and including a separation membrane-flow channel member composite body. The composite body includes a gas separation membrane including a first porous layer and a hydrophilic resin composition layer. The gas separation membrane is folded with the first porous layer being located outside the hydrophilic resin composition layer. The composite body also includes a flow channel member that forms a gas flow channel, the flow channel member being sandwiched in the folded gas separation membrane. The flow channel member is provided with a first cover that covers one end portion of four end portions. The first cover is located closest to a turn-back part of the folded gas separation membrane.
