  • Process and apparatus for providing an inert gas to a large volume atmosphere
    Patent number: 8252090
    Abstract: A system and method is presented for reducing a concentration of ambient air used in a feed stream to form an inerting gas in a pressure swing adsorption system. The method includes introducing ambient air into a pressure swing adsorption system to form an inerting gas, introducing the inerting gas to a large volume of atmosphere, thereby inerting at least a portion of the large volume of atmosphere to form an inerted atmosphere, and removing a portion of the inerted atmosphere and introducing the portion of inerted atmosphere to the pressure swing adsorption system to form the inerting gas, thereby reducing an amount of ambient air utilized to form the inerting gas in the pressure swing adsorption system.
