Document Type and Number:
Japanese Patent JP2020163282
Kind Code:
A
Abstract:
To provide a gas separation membrane system that can suppress running costs.SOLUTION: The gas separation membrane system is provided with: (a) a first gas separation membrane unit 31: (b) a second gas separation membrane unit 32: (c) a third gas separation membrane unit 33; (d) a fourth gas separation membrane unit 34; and (e) pressure boosting means 21, arranged on a raw material gas line 10, which boosts pressure of raw material gas, which is configured so that residues of permeated gas in the second gas separation membrane unit 32, permeated gas in the third gas separation membrane unit 33 and not-permeated gas in the fourth gas separation membrane unit 34 are recirculated into a side closer to an upstream than the pressure boosting means 21 of the raw material gas line 10.SELECTED DRAWING: Figure 1
