Spiral gas separator elements, gas separator modules and gas separators

摘要

A spiral gas separation membrane element having a center tube and a laminate 7 wound around the center tube, wherein the laminate 7 includes a supply side flow path member 3, a gas separation membrane 2, and a permeate side flow path member. (4) has one or more structures superimposed in this order, the permeate side flow path member 4 has a thickness of 400 μm to 1300 μm, and the gas separation membrane 2 includes the hydrophilic resin composition layer 20 and a porous body. The layer 21 and the permeate side surface layer 22 are films superimposed in this order, and the permeate side surface layer 22 faces the permeate side flow path member 4 and has a Young's modulus of 20 MPa to 400 MPa. Spiral type gas separator element.
