Linde and Evonik collaborate on membrane gas separation

Technology company The Linde Group and the specialty chemicals group Evonik Industries have intensified their collaboration in the area of membrane-based gas separation within the framework of the groundbreaking ceremony for the expansion of Evonik’s membrane production facility held in Schörfling (Austria) on September 30. 

The heart of the collaboration comprises Evonik's polymer-based membrane technology, which will be used in the gas separation and purification plants of Linde’s Engineering Division. With this, Linde completes its portfolio, combining all relevant gas separation processes within one company. Evonik’s Sepuran membranes enable gases such as methane, nitrogen, helium, and hydrogen to be particularly efficiently isolated in pure form from gas mixtures, thanks to more selective separation and higher productivity. 

The collaboration between Evonik and Linde has already resulted in a reference plant for helium purification in Mankota (Canada), which started up in August of this year; this first-of-its-kind helium purification facility uses a hybrid process of membrane and Pressure Swing Adsorption (PSA) technology. The new plant processes 250 Mcmd of crude gas, producing industrial-quality helium of 99.999% purity. 

As a leading player in the international plant engineering business, Linde Engineering has delivered more than 4,000 plants across the globe. 

For more than 50 years the High Performance Polymers Business Line of Evonik’s Resource Efficiency Segment has been developing and producing high-performance polymers that allow new resource-efficient developments in a very wide range of fields.
