The Linde Group and specialty chemicals group Evonik Industries have taken a leap forward in membrane-based gas separation processes after commencing construction on a site expansion in Austria.

The groundbreaking ceremony for the development of Evonik’s membrane production facility was held in Schörfling on 30th September, which will see Evonik’s polymer-based membrane technology being used in gas separation and purification plants of Linde’s Engineering Division.

Evonik’s SEPURAN® membranes enable gases such as methane (CH4), nitrogen (N2), hydrogen (H2) and helium (He) to be efficiently isolated in pure form from gas mixtures through more selective separation and higher productivity.

The partnership has already resulted in a reference plant for He purification in Canada with a first-of-its-kind He purification site, which is owned and operated by Weil Group Resources whilst the Tier One corporation handled the design and engineering of the facility, using the pioneering hybrid process of membrane and pressure swing adsorption (PSA) technology. It processes 250,000 m3 of crude gas a day and produces industrial-quality He of 99.99%.

Dr. Axel Kobus, head of Evonik’s Fibres, Membranes and Specialties Product Lines, commented, “The synergies arising from the collaboration between our two companies are evident: The translation of our profound polymer and technology expertise into a powerful and wide-ranging membrane product portfolio perfectly complements Linde’s high expertise in plant engineering and gas separation.”

“The combination offers the ideal conditions to jointly develop new markets for gas separation.”
