  • Method and apparatus for reducing static charges during polymerization of olefin polymers
    Patent number: 6905654
    Abstract: The present invention relates to a method and apparatus for controlling static charges in a fluidized bed olefin polymerization reactor. Static charges which develop in the polymer products are measured and, if they fall outside a predetermined range, static charge control agents are introduced into the reactor. By controlling the static charges in the reactor, sheeting and drooling can be controlled.
    Type: Grant
    Filed: February 7, 2003
    Date of Patent: June 14, 2005
    Assignee: Univation Technologies, LLC
    Inventors: Mark Peter Bartilucci, Ernest Raymond Davis, Jr., Brian J. Egan, Robert Olds Hagerty, Per K. Husby
