  • Mitigation of wax levels in the high pressure low density polyethylene process
    Patent number: 9879098
    Abstract: In the high pressure polymerization of ethylene homopolymers or copolymers, conditions in the high pressure recycle system may lead to the build-up of low molecular weight oligomers and waxes. Sequentially draining knock-out pots, located downstream of a high pressure separator, at regular intervals can reduce the build-up of low molecular weight oligomers and waxes during the high pressure polymerization of alpha olefins.
    Type: Grant
    Filed: May 19, 2015
    Date of Patent: January 30, 2018
    Assignee: NOVA Chemicals (International) S.A.
    Inventors: James A. Auger, Craig Allan Hulet, Ross Donald Moreton, Benjamin Milton Shaw, Amanda Dolores Murphy
