  • Methods and systems for co-feeding waste plastics into a refinery
    Patent number: 11939532
    Abstract: The present application provides a method and a system for recycling a polymer. The method includes introducing polymer into a primary melting extruder, producing a polymer melt that is combined with a fluid oil to at least partially dissolve the polymer melt. A secondary mixing extruder mixes these to form a polymer solution that is introduced into a refinery oil stream, producing a polymer-comprising oil stream, which is fed into a refinery process unit. The system includes a primary melting extruder for forming a polymer melt from polymer. A secondary mixing extruder receives the polymer melt. One or more hydrocarbon inflow conduits for providing a fluid oil to the primary melting extruder and/or the secondary mixing extruder are configured to form a polymer solution from the fluid oil and the polymer melt. There is a feed system outlet for feeding the polymer solution to a refinery oil stream.

  • Extrusion coating resin from tubular reactor
    Patent number: 11396562
    Abstract: A method may include polymerizing ethylene in a tubular reactor, where the polymerization is substantially free of a chain transfer agent. A method may include polymerizing ethylene in a tubular reactor, the ethylene having a specific delivery pressure and the polymerization having one or more specific peak temperatures. The molecular weight of the resulting polyethylene may be controlled by the selection of the delivery pressure and the one or more peak temperatures.
