Linde Engineering and BASF have developed a new process that combines treatment of natural gas for pipeline transportation with the simultaneous recovery of helium, liquid hydrocarbons, and purified carbon dioxide (CO2).
Helium is commonly recovered from natural gas when a cryogenic separation is employed. The hybrid process eliminates the need for cryogenic conditions, giving access to a new highly profitable helium source.
The process consists of two stages of Linde’s HISELECT® Powered by Evonik membranes, an upstream BASF Durasorb™ hydrocarbon removal unit (HRU), an integrated BASF OASE® acid gas removal unit (AGRU) and an integrated Linde Helium PSA (pressure-swing adsorption) unit.
