Abstract
A process for producing hydrogen includes: passing a hydrocarbon feed though purification sorbent(s), combining steam with the purified hydrocarbon and passing the hydrocarbon/steam mixture adiabatically through a bed of steam reforming catalyst, passing the pre-reformed gas mixture through a fired steam reformer to generate a crude synthesis gas mixture, passing the crude synthesis gas mixture through one or more beds of water-gas shift catalyst to generate a shifted synthesis gas mixture, passing the shifted synthesis gas mixture to a membrane shift reactor containing a bed of water-gas shift catalyst and a CO-selective membrane, cooling the hydrogen-enriched gas mixture to below the dew point and separating off the condensate, passing the de-watered hydrogen-enriched gas mixture to COseparation in pressure-swing absorption apparatus, and recycling at least a portion of the purge gas stream as fuel to the fired steam reformer or to the hydrocarbon feed or purified hydrocarbon feed streams.
