Abstract
Apparatus and process for producing a hydrogen-containing product stream and a carbon monoxide-containing product stream from a crude synthesis gas produced in a syngas production unit. Carbon dioxide is removed from the process gas by a non-cryogenic means and the hydrogen-containing product stream is separated from the process gas in a pressure swing adsorber. Residual gas from the pressure swing adsorber is passed to a cryogenic separation unit where the cryogenic separation unit separates the residual gas stream into the carbon monoxide-containing product stream, a hydrogen-enriched stream, a methane-enriched stream, and a carbon monoxide-containing intermediate stream by cryogenic fractionation. At least a portion of the hydrogen-enriched stream is recycled to the pressure swing adsorber.
