A gas separation process and system for integrating a gas permeable membrane system with a multiple bed pressure swing adsorption system to produce a mixed gas product having a preset adjustably controlled gas ratio and a high purity second gas component. The permeate stream from the gas permeable membrane system is fed to the PSA unit and the tail gas from the PSA unit is compressed and blended with the non-permeate stream to form the mixed gas product. The pressure of the permeate stream is controlled to adjustably control the gas ratio of the mixed gas product.

A process for integrating a permeable membrane separating unit having gas permeable membrane with a pressure swing adsorption unit to produce a blended product of mixed gas components from a multi-gas component feedstream containing such gas components comprising the steps of: directing said multi-gas component feedstream to said permeable membrane separating unit to separate said multi-gas component feedstream into a permeate feedstream of more readily permeable gas components and into a mixed component non-permeate feedstream of less readily permeable components; passing said permeate feedstream to said pressure swing adsorption unit to produce a high purity gas component and a tail gas feedstream of mixed permeate gas components; and mixing said tail gas feedstream with said non-permeate feedstream to form said blended product of mixed gas components.
