  • Polymerisation process
    Patent number: 9868802
    Abstract: Polymerization process for the polymerization of monomer in a polymerization system having at least one component attached thereto which component is flushed with a flush medium which enters the polymerization system. Initially, the component is flushed with a first flush medium, and subsequently the component is flushed with a second flush medium.
    Type: Grant
    Filed: June 23, 2016
    Date of Patent: January 16, 2018
    Assignee: INEOS EUROPE AG
    Inventors: Andrew David Bell, Pierre-Marie Cagna, Fabrice Betton, David Heslop, Kevin Peter Ramsay
  • POLYMERISATION PROCESS
    Publication number: 20160297908
    Abstract: The present invention relates to a polymerisation process, and in particular provides a process for the polymeristion of monomer in a polymerisation system having at least one component attached thereto which component is flushed with a flush medium which enters the polymerisation system, wherein initially said component is flushed with a first flush medium, and subsequently said component is flushed with a second flush medium.

  • Polymerisation process
    Patent number: 9376517
    Abstract: Process for the polymerization of monomer in a polymerization system having at least one component attached thereto which is flushed with a flush medium which enters the polymerization system. Initially, the component is flushed with a first flush medium, and subsequently the component is flushed with a second flush medium which differs in composition from the first flush medium. A flush gas containing monomer is used as the flush medium when the polymer production rate is above 10 Te/h.
