SPG Steiner and Evonik to strengthen collaboration in membrane-based gas separation

With immediate effect, SPG Steiner GmbH expands its strategic cooperation agreement with Evonik.

With immediate effect, SPG Steiner GmbH expands its strategic cooperation agreement with Evonik. The specialty chemicals Evonik and the technology group SPG Steiner are successfully cooperating together focusing on the defossilization and plant efficiency of energy industries through Evonik’s gas separation technologies.

“The cooperation with SPG Steiner underlines our strategic approach to shape the transformation of today’s energy sector towards greater efficiency and lower emissions by using our advanced membrane technologies for efficient gas separation. This can only be achieved through strong commitment and engagement with partners along the entire value chain," says Dr. Goetz Baumgarten, Vice President Membranes at Evonik.

“The ongoing global challenges of climate change, raw material scarcity, energy supply, nutrition and healthcare cannot be met without efficient separation technology. Membranes have by far the greatest potential in this regard. SPG Steiner GmbH is proud to renew and cooperate with Evonik, leading the defossilization of the industry creating tomorrows energy - Next Energy”, says Philippe Steiner, Managing Director at SPG Steiner.

The PURAMEM® VOC membrane by Evonik presents a new polymer-based membrane technology for efficient separation of long-chain hydrocarbons from natural gas or nitrogen mixtures.

The technology features a consistently high selectivity over a long period of time under demanding operating conditions and has been optimized for special applications, such as in natural gas processing, emission control in tank farms or in the chemical and process industry.

The modularized process packages of SPG and Evonik feature a small foot print, reduced OPEX and maintenance costs. The design is easily scalable and can be adjusted to any capacity unlike conventional technical approaches.

Evonik is a global membrane technology leader for the gas industry. By offering its innovative gas separation and ion-conducting membranes, the specialty chemicals company makes the transition of today’s conventional energy supply to a sustainable gas economy of tomorrow possible. 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.
