초록
A process for producing nitrogen-rich air by feeding high temperature air at 150° C. or more to an air separation membrane module is described. After being placed at 175° C. for two hours, the air separation module exhibits a shape-retention ratio of 95% or more in one embodiment. The nitrogen-rich air can be fed to a fuel tank for an aircraft, for example.

1. A process for producing nitrogen-rich air from the air using an air separation membrane module including an air separation membrane, the process comprising feeding the air at 175° C. or higher to the air separation membrane, wherein the air separation membrane in the air separation membrane module comprises a material having no glass-transition temperature at 300° C. or lower, wherein for the air separation membrane module,at the initiation of the use, an oxygen-gas permeation rate (P′O2) at 175° C. is 20×10−5 cm3(STP)/cm2·sec ·cmHg or more and a rati...
