Abstract
A process and apparatus for producing a hydrogen-enriched product and recovering COfrom an effluent stream from a hydrogen production unit are described. The effluent from the hydrogen production unit, which comprises a mixture of gases comprising hydrogen, carbon dioxide, water, and at least one of methane, carbon monoxide, nitrogen, and argon, is sent to a PSA system that produces at least two product streams for separation. The PSA system that produces at least two product streams separates the gas mixture into a high-pressure hydrogen stream enriched in hydrogen, optionally a second gas stream containing the majority of the impurities, and a low-pressure tail gas stream enriched in COand some impurities. The CO-rich tail gas stream is compressed and sent to a COrecovery unit, where a CO-enriched stream is recovered. The CO-depleted overhead gas stream is recycled to the PSA system that produces at least two product streams.
