  • Modular compact adsorption bed
    Patent number: 8545604
    Abstract: A modular and compact adsorbent bed structure is disclosed for use in an adsorption-based gas separation plant. The conventional adsorbent bed in a gas separation plant is replaced with a plurality of modular adsorbent bed units connected to make the adsorbent bed structure. The modular design requires lower fabrication and maintenance costs; is easier to transport; and is easier to load with adsorbent material.
    Type: Grant
    Filed: December 19, 2012
    Date of Patent: October 1, 2013
    Assignee: Praxair Technology, Inc.
    Inventors: Ashwin Desai, Cem E. Celik, Mark William Ackley, James Smolarek

  • Multi-port indexing drum valve for VPSA
    Patent number: 7867320
    Abstract: The present invention relates to a dual feed and dual vacuum four bed VPSA process for selectively adsorbing a component from a feed stream, e.g., nitrogen from air, to produce an oxygen-enriched gas stream using a multi-port indexing drum valve, a system comprising a multi-port indexing drum valve and method for operating such a system.
