Title: METHOD FOR INSPECTING SEPARATION MEMBRANE MODULE AND METHOD FOR MANUFACTURING SEPARATION MEMBRANE MODULE
Abstract:
A method for inspecting a separation membrane module (10) is provided with a sealing step for sealing a gas for inspection on a primary side of zeolite membrane (12). The dynamic molecule size for the gas for inspection is greater than 1.07 times the mesh size in the zeolite membrane (12). The gas for inspection has the characteristic of having a rate of reduction for CO2 gas permeation rate in the zeolite membrane (12) of less than 10% when a separation membrane structure (1) is allowed to stand for 60 minutes in the gas for inspection at 25°C and 0.1 MPaG.
