  • Apparatus and method for producing purified hydrogen gas by a pressure swing adsorption processes
    Patent number: 8431082
    Abstract: The invention relates to a method and an apparatus for producing purified hydrogen gas by a pressure swing adsorption process. Further the invention relates to detecting an operating life of adsorbents in a adsorption tower. The method and the apparatus have a gas supply unit for adding an inert gas to an unpurified hydrogen gas and a detector for measuring an inert gas in a purified hydrogen gas discharged from the adsorption tower.
    Type: Grant
