    摘要: A method and system for storing and supplying hydrogen to a hydrogen pipeline in which a compressed hydrogen feed stream is introduced into a salt cavern for storage and a stored hydrogen stream is retrieved from the salt cavern and reintroduced into the hydrogen pipeline. A minimum quantity of stored hydrogen is maintained in the salt cavern to produce a stagnant layer having a carbon dioxide content along the cavern wall and the top of a residual brine layer located within the salt cavern. The compressed hydrogen feed stream is introduced into the salt cavern and the stored hydrogen stream is withdrawn without disturbing the stagnant layer to prevent carbon dioxide contamination from being drawn into the stored hydrogen stream being reintroduced into the hydrogen pipeline. This allows the stored hydrogen stream to be reintroduced into the hydrogen pipeline without carbon dioxide removal.

    摘要: 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 CO2-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 CO2 separation 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.
