  • Method for designing multi-valve uni-direction blowdown system for a high pressure tubular reactor
    Patent number: 10737229
    Abstract: Provided herein is a unidirectional blow down system for a high-pressure tubular reactor with a hyper that minimizes the tube wall metal temperature during a decomposition event wherein the system prevents the reactor walls from reaching a temperature capable of causing the tube metal to austenize. Also provided are methods of designing and methods of operating a unidirectional blowdown system.
    Type: Grant
    Filed: December 2, 2016
    Date of Patent: August 11, 2020
    Assignee: NOVA Chemicals (International) S.A.
    Inventors: Teresa Yuk Woon Leung, Kamal Kamel Botros, Ross Donald Moreton, Benjamin Milton Shaw

  • 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.
