SEPURAN® NG is an especially robust, hollow fibre membrane, which is based on a high-performance plastic that can withstand extreme pressure and temperatures. 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.
How does natural gas processing with Evonik's SEPURAN® NG membrane work?
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.
Use in natural gas sources with high CO2 concentration
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.
