  • Devolatilization apparatus and process
    Patent number: 11976154
    Abstract: In at least one embodiment, a devolatilization vessel includes a first set of one or more devolatilization plates and a second set of one or more devolatilization plates. A first distributor is above the first set of one or more devolatilization plates and the second set of one or more devolatilization plates. A second distributor is above the second set of one or more devolatilization plates. In at least one embodiment, a process of forming a polymer includes forming a first polymer solution having a first viscosity and forming a second polymer solution having a second viscosity. The process includes flowing the first polymer solution and the second polymer solution to a devolatilization vessel. The process includes removing volatiles from the first polymer solution and the second polymer solution in the devolatilization vessel to form a devolatilized first polymer melt and a devolatilized second polymer melt.

  • Processes and apparatus for continuous solution polymerization
    Patent number: 9175118
    Abstract: This invention relates to a blocked process for producing polymers of high and low molecular weights utilizing the same polymer separator. The separator is operated in a different mode depending on the molecular weight of the polymer being produced such that the separation system is operated in flash mode for the separation of low molecular weight polymers and operated in lower critical solution temperature (LCST) mode for the separation of high molecular weight polymers.
