Evonik is building a new hollow fiber spinning plant for the production of gas separation membranes at its Austrian site in Schörfling am Attersee. With the new capacity, the group aims to meet the  demand for SEPURAN membranes in hydrogen, biogas, nitrogen, and natural gas applications. The plant is scheduled to come on stream in the first quarter of 2023. 

"The gas separation market is convinced of our innovative membrane technology. Having developed and established the biogas industry in close cooperation with our partners, we are establishing our SEPURAN membranes as the new standard for efficient gas separation in demanding nitrogen, hydrogen and natural gas applications. The additional production capacities will secure our growth targets in these important markets for us," said Dr. Goetz Baumgarten, Head of the Membranes Innovation Growth Field at Evonik.

SEPURAN Noble membranes extract hydrogen transported through natural gas pipelines selectively from the CH₄/H₂ gas mixture at the delivery points. The base material - the a high-performing polymer polyimide - is produced and processed into fine hollow fibers in Schörfling.
