摘要:
The present invention involves an efficient process for separating components of a gas stream by integrating a cryogenic separation unit and a membrane separation unit. One embodiment provides for the generation of one or more nitrogen-rich streams in the gas or liquid phase, or both, from a stream comprising oxygen and nitrogen; e.g., air.
