Abstract
A process and apparatus for producing a hydrogen-enriched product and recovering CO2 from an effluent stream from a hydrogen production process unit are described. The process utilizes a CO2 recovery system integrated with a PSA system that produces at least two product streams to recover additional hydrogen and CO2 from the tail gas stream of a hydrogen PSA unit in the hydrogen production process.
