MOSCOW (MRC) -- Evonik has launched new membrane for efficient natural gas processing - SEPURAN NG is an especially robust, hollow-fiber membrane, which is based on a high-performance plastic that can withstand extreme pressure and temperatures, as per the company's press release.
This enables particularly selective separation of the sour gases from the natural gas, high tolerance of the higher hydrocarbons contained in the natural gas, and consistently high performance of the membrane throughout its lifetime. Overall, Evonik’s innovative separation technology features significantly increased recovery of methane, which has a corresponding effect on the profitability of natural gas processing plants.
The modular structure of SEPURAN NG has been designed for conventional, membrane-based natural gas processing plants so that, during the membrane exchange, no further adaptations are required to the existing equipment. For this purpose, Evonik is working together with established, world-leading gas separation companies that support plant operators in process implementation in order to make the most of the advantages of the new membranes.
The membrane is designed for the challenging process conditions of natural gas processing with complex gas compositions and typical pressure and temperature conditions up to 70 C. It can be used particularly effectively in natural gas sources with a high concentration of carbon dioxide because, under these conditions, the separating properties of the membrane remain intact.
Evonik’s SEPURAN product family includes innovative membranes for biogas upgrading, nitrogen generation, and helium and hydrogen processing. They are produced at the Evonik site in Schorfling (Austria). The basic material - the high performance plastic - is manufactured in the neighboring Evonik site in Lenzing. The new SEPURAN NG membrane for natural gas processing rounds off the product portfolio.
As MRC informed before, in late June 2018, the technology company The Linde Group and the specialty chemicals company Evonik Industries concluded an exclusive cooperation agreement on the use of membranes for natural gas processing. The two companies will jointly promote membrane technology - Evonik on the membrane and polymer side and Linde’s Engineering Division as the system integrator for the complete membrane package units. Evonik’s established membrane technology will serve as the basis. The joint product will be marketed by Linde as the "HISELECT powered by Evonik" high-performance membrane package unit.
Evonik, the creative industrial group from Germany, is one of the world leaders in specialty chemicals. Its activities focus on the key megatrends health, nutrition, resource efficiency and globalization. Evonik benefits specifically from its innovative prowess and integrated technology platforms. Evonik is active in over 100 countries around the world.
