    摘要： A segregated steam system and process in a hydrogen production facility wherein boiler feed water is heated by indirect heat exchange with a reformate, the heated boiler feed water is used to heat water condensate formed from the reformate, the heated water condensate is passed to a first steam drum for producing steam for a reformer feed gas mixture, and a second portion of the heated boiler feed water is passed to a second steam drum for producing steam for export.

    摘要： Method of making a product gas mixture comprising providing a first gas mixture, contacting the first gas mixture with a lean absorber liquid at a first pressure and absorbing a portion of the first gas mixture in the lean absorber liquid to provide a rich absorber liquid and a non-absorbed residual gas, pressurizing the rich absorber liquid provide a pressurized rich absorber liquid, stripping the pressurized rich absorber liquid with a stripping gas at a second pressure greater than the first pressure to provide a pressurized lean absorber liquid and the product gas mixture, and reducing the pressure of the pressurized lean absorber liquid to provide the lean absorber liquid at the first pressure. The first gas mixture may be a synthesis gas comprising hydrogen and carbon dioxide.

    摘要： Process for producing hydrogen where multiple streams are heated in parallel with reformate that has passed from the shift reactor. Each of the multiple streams are heated from a temperature below the dew point of the reformate to a temperature above the dew point of the reformate by reformate that is cooled from a temperature above the dew point of the reformate to a temperature below the dew point of the reformate. The multiple streams can include two or more of water condensate, boiler feed water, hydrocarbon feedstock, and pressure swing adsorption unit by-product gas.
