HYDROGEN PRODUCTION FROM STEAM CRACKING TAIL GAS WITH MEMBRANE REACTOR

Abstract: methods of hydrogen (h) production is provided. the method includes: performing steam cracking of a feed to generate an olefin product and a tail gas including methane; reforming the methane to form a syngas including hand carbon monoxide (co); providing the syngas into a reaction vessel to a region external to a tubular membrane in the reaction vessel; providing a steam into the reaction vessel to the region; performing water-gas shift reaction (wgs) of the syngas in the reaction vessel to form a product gas including the hand carbon dioxide (co); diffusing the hin the product gas through the tubular h-selective membrane into its bore; discharging the hfrom the bore of the tubular h-selective membrane; discharging a remainder of the product gas from the external region; and generating heat using the has fuel, where the heat is used for the steam cracking.
