The CMS membranes are produced by pyrolyzing polyimides like 6FDA:BPDA-DAM and show improved production (flux) and exceptional separation (selectivity) when compared to the precursor polymer and polymeric membranes in general.
The impact of impurities on the CMS membrane must be understood in order to use it in actual production plant applications. This paper will discuss common impurities found in the ethylene plantâs purification train, specifically, the potential impact of these impurities on the membrane. These impurities include hydrogen sulfide, water, carbon dioxide, acetylenics, and carbon monoxide.
