  • Patent number: 8394174
    Abstract: The present invention provides for various processes for recovering high purity gaseous hydrogen and high purity gaseous carbon dioxide from the gas stream produced using steam hydrocarbon reforming, especially steam methane reforming, utilizing a H2 pressure swing adsorption unit in combination with either a CO2 pressure swing adsorption unit in combination with a membrane separation unit or a CO2 pressure vacuum swing adsorption unit in combination with a membrane separation unit. The present invention further relates to a process for optimizing the recovery of carbon dioxide from waste gas streams produced during the hydrogen purification step of a steam hydrocarbon reforming/water gas shift reactor/H2 pressure swing adsorption unit utilizing either a CO2 pressure swing adsorption unit in combination with a membrane separation unit or a CO2 pressure vacuum swing adsorption unit in combination with a membrane separation unit.

  • Patent number: 8303930
    Abstract: The present invention relates to various processes for recovering high purity gaseous hydrogen and high purity gaseous carbon dioxide from the gas stream produced using steam hydrocarbon reforming, especially steam methane reforming, utilizing a H2 pressure swing adsorption unit followed by either a CO2 vacuum swing adsorption unit or a CO2 vacuum swing adsorption unit in combination with an additional CO2 pressure swing adsorption unit. By using an uncoupled H2 PSA and CO2 VSA unit it is possible to produce high purity H2 and high purity CO2. The present invention further relates to a process for optimizing the recovery of CO2 from waste gas streams produced during the hydrogen purification step of a steam hydrocarbon reforming/H2 pressure swing adsorption unit utilizing either a CO2 vacuum swing adsorption unit or a CO2 vacuum swing adsorption unit in combination with a CO2 pressure swing adsorption unit.
