  • Patent number: 11918991
    Abstract: A reformer furnace is provided for use in converting a hydrocarbon feed into a synthesis gas stream. The reformer furnace includes at least one bayonet reformer tube located at least partly within an enclosed volume. The reformer furnace includes a first support arranged to support the second end portion of the at least one bayonet reformer tube against the second endwall of the reformer furnace.

  • Publication number: 20240059563
    Abstract: A plant and process for producing a hydrogen rich gas are provided, said process comprising the steps of: reforming a hydrocarbon feed in a reforming step using an autothermal reformer (ATR) thereby obtaining a synthesis gas comprising CH4, CO, CO2, H2 and H2O; shifting said synthesis gas in a shift configuration including a high temperature shift step; passing the shifted syngas to a first hydrogen purification unit, e.g. a PSA unit; passing a portion of the off-gas from the first hydrogen purification unit to a second hydrogen purification unit, and using off-gas from the first and second hydrogen purification unit as e.g. fuel for a preheater unit before the ATR.

  • Publication number: 20230294985
    Abstract: A plant and process for producing a hydrogen rich gas are provided, said process comprising the steps of: reforming a hydrocarbon feed in an autothermal reformer thereby obtaining a syngas; shifting said syngas in a shift configuration including a high temperature shift step; removal of CO2 in a CO2-removal section by amine wash thereby forming a hydrogen rich stream, a portion of which is used as low carbon hydrogen fuel, as well as a CO2-rich gas and a high-pressure flash gas stream. The high-pressure flash gas stream is advantageously integrated into the plant and process for further improving carbon capture.

  • Publication number: 20230271829
    Abstract: A plant and process for producing a hydrogen rich gas and improved carbon capture are provided, said process comprising the steps of: reforming a hydrocarbon feed by optional prereforming, autothermal reforming (ATR), yet no primary reforming, thereby obtaining a synthesis gas; shifting said synthesis gas in a shift section including a high temperature shift step; removal of CO2 upstream hydrogen purification unit, thereby producing a hydrogen rich stream and an off-gas stream, and where at least part of the off-gas stream is recycled to the process, thus to the ATR and optional prereforming, and/or to the shift section.

  • Publication number: 20230114501
    Abstract: Process and plant for producing a synthesis gas by catalytic steam reforming of a hydrocarbon feedstock in a steam reforming unit, wherein water is removed from the synthesis gas as a process condensate, wherein boiler feed water is introduced in the process, and wherein said process or plant produces at least two separate steam streams: a pure steam which is generated from at least a portion of said boiler feed water by the cooling of synthesis gas, and a process steam which is generated by evaporating at least a portion of the process condensate by using synthesis gas, optionally together with pure steam and/or flue gas from the steam reforming unit.
