  • Process of preparing polyolefin with the discontinuous addition of a thermal runaway reducing agent
    Patent number: 11773192
    Abstract: The present invention relates to a process for the continuous preparation of a polyolefin from one or more ?-olefin monomers in a reactor system, the process for the continuous preparation of polyolefin comprising the steps of: +feeding a polymerization catalyst to a fluidized bed through an inlet for a polymerization catalyst; +feeding the one or more monomers to the reactor, +polymerizing the one or more monomers in the fluidized bed to prepare the polyolefin; +withdrawing polyolefin formed from the reactor through an outlet for polyolefin; +withdrawing fluids from the reactor through an outlet for fluids and transporting the fluids through first connection means, an heat exchanger to cool the fluids to produce a cooled recycle stream, and through second connection means back into the reactor via an inlet for the recycle stream; wherein a thermal run away reducing agent (TRRA) is added to the reactor in a discontinuous way.

  • PROCESS OF PREPARING POLYOLEFIN WITH THE DISCONTINUOUS ADDITION OF A THERMAL RUNAWAY REDUCING AGENT
    Publication number: 20220332855
    Abstract: The present invention relates to a process for the continuous preparation of a polyolefin from one or more ?-olefin monomers in a reactor system, the process for the continuous preparation of polyolefin comprising the steps of: feeding a polymerization catalyst to a fluidized bed through an inlet for a polymerization catalyst; feeding the one or more monomers to the reactor, polymerizing the one or more monomers in the fluidized bed to prepare the polyolefin; withdrawing polyolefin formed from the reactor through an outlet for polyolefin; withdrawing fluids from the reactor through an outlet for fluids and transporting the fluids through first connection means, an heat exchanger to cool the fluids to produce a cooled recycle stream, and through second connection means back into the reactor via an inlet for the recycle stream; wherein a thermal run away reducing agent (TRRA) is added to the reactor in a discontinuous way.
