  • Process and apparatus for olefin polymerization in a fluidized bed reactor
    Patent number: 7977436
    Abstract: A process and apparatus for gas phase polymerization of olefins in a fluidized bed reactor are disclosed. The process and apparatus employ a vertically oriented fines ejector in order to reduce fouling and reactor downtime.
    Type: Grant
    Filed: March 31, 2010
    Date of Patent: July 12, 2011
    Assignee: Westlake Longview Corp.
    Inventors: Matthew Howard Scott, Kenneth Alan Dooley, Bailey James Salmon, Mark Dewayne Lorenz, Paul Keith Scherrer, Robert Lin, David Lynn Meade, Wayne Scott Strasser, Dwayne Ray Leonard
  • Gas distribution plate for fluidized-bed olefin polymerization reactors
    Patent number: 7939025
    Abstract: A gas distribution plate for fluidized-bed, olefin polymerization reactors is provided. In addition to holes for distributing a fluidizing gas, the plate comprises a plurality of hollow projections for introducing a fluid into the fluidized-bed reactor. The hollow projections, which can be tubes or pipes, extend above the plate towards the fluidized bed and serve a number of purposes. The projections can break apart or penetrate fallen polymer agglomerates or sheets. They can be equipped with flow or pressure sensors to detect a decrease in flow rate or an increase in pressure drop across the projections, which is an indicator of the presence and/or size of fallen polymer agglomerates or sheets. The projections can also break apart the agglomerates or sheets into smaller pieces by delivering blasts of fluid directly into the agglomerates or sheets.
