Open the CIPO recordAbstract From the Canadian patent
The present invention involves a process for separating components of a feed gas containing acid gases and hydrocarbons to form a CO2-rich stream, an H2S-rich stream and a hydrocarbon-rich stream. Separation is achieved by initially passing the feed gas through a plurality of membrane separation units to produce a hydrocarbon stream and an acid gas stream. The acid gas stream undergoes further separation to produce a CO2-rich product stream and an H2S-rich stream. This process is especially adaptable for treating natural gas streams and gas streams resulting from enhanced oil recovery operations.
