Title:
HOLLOW FIBER MICROPOROUS MEMBRANE, AND GAS SEPARATION MEMBRANE MODULE WITH SAME BUILT THEREINTO
Document Type and Number:
WIPO Patent Application WO/2023/027052
Kind Code:
A1
Abstract:
[Problem] To provide a high-quality hollow fiber microporous membrane that is concurrently provided with high levels of gas permeability, gas selectivity, and strength. The present invention is characterized by a hollow fiber microporous membrane wherein the carbon dioxide gas flux is 10×10–5 to 200×10–5 (cm3(STP)/cm2/sec/cmHg), the value (carbon dioxide gas flux/nitrogen gas flux) that results from dividing the carbon dioxide gas flux value by the nitrogen gas flux value (cm3(STP)/cm2/sec/cmHg) is 1.3 or greater, and the tensile strength is 0.5 cN/dtex or greater.
