Abstract
In a gas separation system, a retentate gas discharge port of a first unit Uand a gas inlet port of a second unit Uare connected by a retentate gas discharge line. A permeate gas discharge port of Uand a gas inlet port of a third unit Uare connected by a permeate gas discharge line. A feed gas mixture supply line is connected to a gas inlet port of U. A permeate gas discharge port of Uand the feed gas mixture supply line are connected by a permeate gas return line. A retentate gas discharge port of Uand the feed gas mixture supply line are connected by a retentate gas return line. At least in operation, the gas permeability of Uis higher than that of U, and the gas selectivity of Uis higher than that of U
