Evonik Industries AG is a global membrane technology leader for the gas industry.
Evonik boosts the chemistry of high-performance polymers into highly selective SEPURAN®, PURAMEM® and DURAION® membranes for all gas separation markets. SEPURAN® membranes make it possible to separate gases such as methane (CH₄), nitrogen (N₂), or hydrogen (H₂) from gas mixtures. PURAMEM® membranes separate long-chain hydrocarbons from natural gas or nitrogen mixture. With DURAION®, Evonik enables affordable, electrolytic production of green hydrogen. The advantages of Evonik’s innovative membrane technology are more precise separation and higher productivity. It does not need any auxiliary materials or chemicals. No waste or wastewater is produced that would otherwise require treatment or disposal.
