<p>PROBLEM TO BE SOLVED: To provide a purge gas distributor capable of rapidly and easily adjusting the flow rates of a purge gas to a plurality of gas separation membrane modules when the modules are connected in parallel. SOLUTION: The gas outlet side caps 11 of a plurality of gas separation membrane modules 1 are connected to a manifold unit 12 and each branch communicating passage 25 of the manifold unit 12 is lined to the purge inlet port 18 of each of the gas separation membrane modules 1. The flow rates of a purge gas to the gas separation membrane modules 1 are adjusted together by a flow rate adjusting means 15 such as a needle valve while monitoring a pressure gauge 26 attached to the manifold unit 12.</p> |
