Abstract: A system and method for discharging a transfer slurry from a first polymerization reactor through a transfer line to a second polymerization reactor, the transfer slurry including at least diluent and a first polyethylene. A product slurry is discharged from the second polymerization reactor, the product slurry including at least diluent, the first polyethylene, and a second polyethylene. The velocity, pressure drop, or pressure loss due to friction in the transfer line is determined, and a process variable adjusted in response to the velocity, pressure drop, or pressure loss not satisfying a specified value.

Abstract: Provided herein are methods of inhibiting polymerization of vinyl aromatic monomers. The methods include distilling a vinyl aromatic monomer in a distillation column to form a vinyl aromatic monomer distillate; removing the vinyl aromatic monomer distillate from the distillation column; combining the vinyl aromatic monomer distillate with 4-tert-butylcatechol (TBC) to form a treated distillate; and adding a reflux liquid that includes the treated distillate to the distillation column liquid of the distillation column. An added oxygen gas may be present in a distillation column liquid in an amount of at least 1 ppmw, based on the weight of the vinyl aromatic monomer.
