ABSTRACT:
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.
