ECN Grants Ceramiques Techniques Industrielles License on HybSi Nanofiltration Membrane Technology

(Nanowerk News) Ceramiques Techniques Industrielles (CTI), as one of the market leaders in inorganic membranes, has obtained a license for the commercialisation of the HybSi® membrane technology from ECN. The HybSi® nanosieve allows the purification of various industrial solvents at a reduced cost and at an enhanced efficiency. It further combines an outstanding performance with unprecedented long term stability.
Important fields of application can be found in the production of bio-fuels and in the separation of azeotropic mixtures. In comparison with conventional separation technologies, major gains in the energy efficiency and improvements of the product quality can be obtained. The unprecedented stability in acid and aggressive conditions at high temperatures of the HybSi® membranes allow for a revolutionary step in the utilisation of pervaporation membranes. The HybSi® membrane technology was originally developed by ECN, in collaboration with the Universities of Twente and Amsterdam.
Francois Garcia (Chairman CTI): "This license on the HybSi® membrane technology allows us to expand our portfolio from filtration processes to molecular separations. In recent years, we have doubled our turn over and we anticipate that a significant growth will come from this license. After the inauguration of the new facilities of our sister company Orelis Environment in October, this is the second important achievement within a few months. We will work together with our clients and partners to present a commercial attractive solution to challenging separations problems during 2012."
Jaap Vente (Manager Membrane Technology, ECN): "We are very pleased that a market leader in the field of ceramic membranes can profit from the commercial opportunities of our HybSi® membrane technology. We are convinced that the competitiveness of our membrane system will increase significant and that large scale application has come another step closer to reality."
