Title:
GAS SEPARATION MEMBRANE ELEMENT, GAS SEPARATION MEMBRANE MODULE, AND GAS SEPARATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/153062
Kind Code:
A1
Abstract:
This gas separation membrane element includes: a gas separation membrane including a first porous layer and a non-porous resin composition layer; a feeding-side space for feeding a starting material gas to the gas separation membrane; a permeation-side space for a permeated gas that has been permeated through the gas separation membrane; and a sealing part for preventing the starting material gas and the permeated gas from mixing. The gas separation membrane element is such that if the pressure [kPaG] in the supply-side space is increased from P1 to P2 and is then decreased to P3, the degrees of permeation [mol/(m2·s·kPa)] of a test gas at the pressures P1, P2 and P3 are respectively defined as F1 to F3, each of P1 and P3 is set to 500 kPaG and P2 is set to a pressure at which F2/F1 = 2, then the relationship in formula (I) is satisfied. Formula (I): F3/F1 ≤ 2.0
