Abstract

An object of the present disclosure is to provide a new method for separating refrigerant gas. The method includes a first step of supplying a feed gas containing at least a refrigerant gas A and a refrigerant gas B to a first module to obtain a first separated gas and a first retentate gas, each having a different composition from the feed gas; a second step of supplying the first separation gas to a second module to obtain a second separation gas and a second retentate gas, the second separation gas and the second retentate gas having different compositions from the first separation gas; A method of gas separation, wherein at least one of the first module and the second module comprises a molecular sieve membrane.
