  • METHOD AND SYSTEM FOR PRODUCING HYDROGEN USING AN OXYGEN TRANSPORT MEMBRANE BASED REFORMING SYSTEM WITH SECONDARY REFORMING
    Publication number: 20160152469
    Abstract: A method and system for producing hydrogen using an oxygen transport membrane based reforming system is disclosed that carries out a primary reforming process within a reforming reactor, and a secondary reforming process within a reactively driven and catalyst containing oxygen transport membrane reactor with or without an auxiliary source of heat to support primary reforming process within the reforming reactor to first form a synthesis gas product. The auxiliary source of heat is disposed within the oxygen transport membrane based reforming system proximate to the reforming reactors and comprises an auxiliary oxygen transport membrane reactor or a ceramic burner. The synthesis gas product is further treated in a separate high temperature water gas shift reactor and optionally in a separate low temperature water gas shift reactor. Hydrogen is produced from the resulting hydrogen-enriched gas using hydrogen PSA.
