A new membrane for natural gas processing

By Chemical Engineering |

Sepuran NG (photo) is a hollow-fiber membrane based on a high-performance plastic that can withstand extreme pressures and temperatures. This enables selective separation of sour gases from natural gas, with a high tolerance of higher hydrocarbons contained in the natural gas and consistently high performance of the membrane throughout its lifetime. It 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. It can be used particularly effectively in natural gas sources with a high concentration of CO 2 because, under these conditions, the separating properties of the membrane remain intact. — Evonik Industries AG, Essen, Germany
