  • Patent number: 8591769
    Abstract: The present invention is a method of reducing the carbon dioxide balance from a reformer furnace flue gas to the high pressure syngas exit water gas shift reaction unit. Introducing a heated gas mixture into at least one pre-reforming chamber. The heating being provided by indirect heat exchange with one or more of an SMR furnace flue gas or an SMR furnace syngas introducing the gas mixture into a standard H2 PSA unit, wherein the gas mixture is separated into a hydrogen enriched stream and a PSA tail gas stream; introducing the PSA tail gas stream into a CPU system, wherein the PSA tail gas stream is separated into a carbon dioxide enriched stream, a hydrogen rich stream, and a residual stream, and introducing the residual stream as fuel into the reformer furnace along with natural gas.

  • Publication number: 20130156686
    Abstract: The present invention is a method of minimizing the emissions of carbon dioxide from a reformer furnace flue gas to the high pressure syngas exit water gas shift reaction unit. Including heating a first gas mixture by indirect heat exchange with one or more of an SMR furnace flue gas or an SMR furnace syngas, further heating the pre-reformed mixture in a primary reformer, thereby generating a second gas mixture comprising hydrogen, carbon monoxide, carbon dioxide, and a flue gas. Introducing the gas mixture into a standard H2 PSA unit, wherein the gas is separated into a hydrogen enriched stream and a PSA tail gas stream, and introducing PSA feed or tail gas stream into a carbon dioxide removal system, wherein the flue gas is separated into a residual flue gas stream and a carbon dioxide enriched stream.

  • Publication number: 20080078177
    Abstract: Systems and methods for regasifying liquefied natural gas (LNG) are provided. The LNG is regasified by transferring heat from a steam methane reforming reaction to the LNG. In one embodiment, heat is transferred to the LNG from a synthesis gas produced in a steam methane reforming reaction. In another embodiment, heat is transferred to the LNG from a flue gas provided from a furnace heating a steam methane reforming reactor. By using excess heat from the steam methane reforming process, less energy may be consumed to regasify LNG.
