Pressure effect at permeability and deformation of the hollow fiber membrane gas separation module

Abstract

In this paper, the deformation effect in the gas separation process of the hollow fiber membrane module is considered. A technique of gas permeability measurement in a commercial gas separation hollow fiber membrane module is provided. It is determined that permeability and selectivity are nonlinearly dependent on the pressure of the feed stream, this is justified by competing factors. The results of this work will allow introducing the membrane modules into hybrid gas separation units, in particular, into the drying unit of compressed gas.
