  • Publication number: 20220227903
    Abstract: A process for preparing an ethylene polymer in a suspension polymerization including the steps of separating the formed suspension of ethylene polymer particles in a solid-liquid separator into wet ethylene polymer particles and mother liquor, drying the wet ethylene polymer particles by a gas stream and forming a gas stream carrying a hydrocarbon load, and thereafter separating the hydrocarbon load from the gas stream and thereby forming a liquid hydrocarbon recover stream, transferring a part of the mother liquor into a work-up section including an evaporator for producing a wax-depleted portion of the mother liquor and a diluent distillation unit for producing isolated diluent from the wax-depleted portion of the mother liquor, wherein a first part of the hydrocarbon recover stream is transferred to the diluent distillation unit without passing the evaporator for producing the wax-depleted portion of the mother liquor.

  • Patent number: 9650454
    Abstract: A slurry polymerization process comprising polymerizing monomers in a reactor comprising baffles, a first slurry feed line for returning cooled slurry from a cooler and optionally a second slurry feed line for transferring reactor slurry from a previous reactor of a cascade of polymerization reactors, wherein the baffle top, the first slurry feed line discharge end and the second slurry feed line end are located below the reactor liquid level.
