Abstract
Processes for producing a hydrogen-enriched gas stream are described. A hydrocarbon containing feed is processed in a hydrogen production process unit, and the synthesis gas formed is subjected to a water gas shift reaction. The shifted synthesis gas is sent for processing to recover hydrogen and carbon dioxide. The hydrogen and carbon dioxide recovery processes involve separating a purified hydrogen product stream and a purified carbon dioxide stream from the shifted synthesis stream and recycling synthesis gas to the reforming feed after recovery of COand H, thereby avoiding carbon slip from the process and lowering the overall carbon intensity.
