Evonik Industries identified a potential new application for one of their high-performance polymers, which it believed would create added value when used to produce a gas separation membrane. Polymer features in gas separation applications had already formed the basis of several doctoral research projects at the University of Twente. Evonik Industries asked EMI Twente to conduct a feasibility study to determine whether it would be possible to develop a hollow-fibre membrane suitable for gas separation. Having performed a successful proof-of-principle, we transferred the knowledge and technology needed to manufacture the membrane to Evonik. Our input formed the basis for the further development and commercialization of the SEPURAN® product family (www.sepuran.com).
