Evonik is one of the world leaders in specialty chemicals. The company is active in more than 100 countries around the world and generated sales of €18.5 billion and an operating profit (adjusted EBITDA) of €2.49 billion in 2022. Evonik goes far beyond chemistry to create innovative, profitable and sustainable solutions for customers. About 34,000 employees work together for a common purpose: We want to improve life today and tomorrow.
Membranes for all gas separation markets
As global technology leader, 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 requires comparatively less energy and does not need any auxiliary materials or chemicals. No waste or wastewater is produced that would otherwise require treatment or disposal.
Thanks to the group’s many years of expertise in polymer chemistry and backward integration, Evonik adjusts the membrane properties already at the development stage of the base material—the high-performance polymer—to produce particularly selective, productive, and robust membranes that can withstand extreme pressures and temperatures in challenging conditions.
Enabling sustainable gas economy
Following the Sustainable Development Goals of the United Nations, Sustainability is the key growth driver and the cornerstone of our product portfolio, investments and innovation management and thus an integral part of Evonik’s strategy. With the innovative gas separation SEPURAN®, PURAMEM® as well as the advanced ion-conducting DURAION® membrane technologies, the specialty chemicals company makes the transition of today’s conventional energy supply to a sustainable gas economy of tomorrow possible.
