Abstract

The long-term stability of membranes is determined mainly by their sensitivity to pollutants. Their stability was tested using a novel, multichannel measuring system, which is based on pressure differences. This measuring system is suitable to determine the changes in permeability of polymer membranes. The damaging effects of H2S, BTX and n-dodecane were investigated in terms of polyimide gas separation membranes using nitrogen gas.
