The Linde Group (Munich, Germany; www.the-linde-group.com) and Evonik Industries AG (Essen, Germany; www.evonik.com) have concluded an exclusive cooperation agreement on the use of membranes for natural gas processing. The two companies will jointly promote
In this hybrid helium-recovery process, hollow-fiber membrane units concentrate a crude gas stream that is subsequently fed to a pressure-swing adsorption process, which purifies the stream to 99.999% helium
membrane technology â€“ Evonik on the membrane and polymer side and Lindeâ€™s Engineering Division as the system integrator for the complete membrane package units. Evonikâ€™s established membrane technology will serve as the basis. The joint product will be marketed by Linde as the â€œHISELECT powered by Evonikâ€ high-performance membrane package unit.
Tobias Keller, head of the Adsorption and Membrane Plants Product Line of Lindeâ€™s Engineering Division, says: â€œWeâ€™re delighted to be extending our successful collaboration with Evonik to the important gas separation market of natural gas processing. HISELECTâ„¢ membranes are opening up new and innovative options in gas separation, especially in combination with our other established processes. With this, weâ€™re consolidating our position as the worldâ€™s leading company for gas separation technologies as well as suppliers of complete separation packages.â€
At the heart of the collaboration lies Evonikâ€™s polymer-based membrane technology. The specialty chemicals company has developed this technology further for the area of natural gas and has recently commercialized it. It is the key component in Lindeâ€™s new HISELECTâ„¢ membrane, which the technology group will market globally in complete membrane package units for onshore gas separation and upgrading plants.
