GAS SEPARATION COMPOSITE MEMBRANE, AND GAS SEPARATION MODULE, GAS SEPARATION APPARATUS AND GAS SEPARATION METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a gas separation composite membrane having excellent gas permeability, yet achieving high gas separation selectivity and high membrane-formation aptitude and over-time stability; and to provide a module and a gas separation apparatus using the same.

SOLUTION: The gas separation composite membrane has a gas separation layer containing a crosslinked polyimide resin at a gas-permeable support layer upper side. The crosslinked polyimide resin has a structure in which a polyimide compound is crosslinked and linked, and the polyimide compound is a copolymer having at least an imide group-containing monomer component and a monomer component having a specific polar group. The module and the gas separation apparatus use the gas separation composite membrane.
