  • Publication number: 20230399421
    Abstract: Disclosed herein is a method comprising discharging from a reactor to an absorber a product stream that comprises a polymer or interpolymer, a solvent and hydrochloric acid; absorbing the hydrochloric acid from the product stream in the absorber; discharging the product stream now devoid of substantially all hydrochloric acid to a first heat exchanger; wherein the first heat exchanger is operative to condense the product stream devoid of hydrochloric acid from the absorber; discharging a condensate from the first heat exchanger to a collection drum that is operative to receive a condensate from the first heat exchanger; splitting up the condensate in the collection drum into a slip stream and a second stream; and discharging the slip stream to a compressor; wherein the compressor is operative to pressurize the slip stream prior to recycling it to the absorber.

  • Patent number: 11814456
    Abstract: A method of producing bimodal ethylene-based polymer includes reacting ethylene monomer and C3-C12 ?-olefin comonomer in the presence of a first catalyst in an agitated reactor to produce a first polymer fraction, and outputting effluent from the agitated reactor. A second catalyst is added to the effluent downstream of the agitated reactor and upstream from a non-agitated reactor, the second catalyst facilitates production of a second polymer fraction having a density and melt index (I2) different from the first polymer fraction. The second catalyst and effluent are mixed in at least one mixer. The second catalyst, second polymer fraction, and the first polymer fraction are passed to the non-agitated reactor; and additional ethylene monomer, additional C3-C12 ?-olefin comonomer, and solvent are passed to the non-agitated reactor to produce more second polymer fraction and thereby the bimodal ethylene-based polymer.
