Permeation properties
Web1. nov 2007 · Gas permeabilities of pure CO2, H2S, CH4, O2, and N2 gases were measured using the indigenously built permeation cell incorporated into a high-pressure gas separation manifold. At the feed pressure of 1 MPa, the membrane exhibited permeances of 15.2 GPU for CO2 and 51.6 GPU for H2S with selectivities of 14.4 and 49.1 for … WebAbstract A series of hydroxyl-group containing polyimides (HPIs) were prepared in order to investigate the structure-gas permeation property relationship. Each polymer membrane …
