  • Raw material efficiency method and process
    Patent number: 8293853
    Abstract: A method and apparatus are disclosed for controlling product discharge from a fluidized bed reactor and for minimizing the loss of the unreacted monomer in the fluidizing gas upon removing the solid polymer product from the reactor. The method and apparatus utilize at least one detector in the product tank or its vent line and a control system in communication with the detector and the product tank fill valve, along with certain algorithms, to adjust by an iterative process, the product discharge time, thereby maximizing resin fill in the product tank and minimizing the lost reactor gas volume.
    Type: Grant

    Date of Patent: October 23, 2012
    Assignee: Univation Technologies, LLC
    Inventors: John R. Parrish, Jeffrey B. Drabish, Oscar M. Longoria, Jr., James L. Swecker, II
