  • Debottlenecking of existing polyester plants
    The enormous need for polymers worldwide emerged a typical problem to polymer plant owners. Although their plants have been designed for a certain capacity, a higher throughput is always requested. Sometimes the capacity is increased by more or less than 200%. Most of the machines and reactors

  • Handbook of Polymer Reaction Engineering, Two Volumes
    6.8 Emulsion Polymerization Reactors 286 .
  • Single-Site Catalysts for Propylene-Based Polymers
    The polymer catalyst yield in turn depends on catalyst activity/time/temperature relationships (catalyst life), and the residence time within the polymerization reactor .
  • Polystyrene
    The polymerization reactors may be conventional completely mixed jacketed stirred tank reactors, linear plug flow tower or column reactors, or reactors of proprietary designs such as Fina’s horizontal plug flow reactor (56197).
  • Linear Low Density Polyethylene
    The resulting catalyst slurry is fed to the polymerization reactor .
  • Computationally Efficient Model Predictive Control Algorithms
    The computer was used for control for the first time in 1959 (in a polymeri- sation reactor control system) [15].

  • Ethylene
    Molding resins containing at least 80 wt% of methyl methacrylate and up to 20 wt% of methyl, ethyl, and (or) butyl acrylates are produced continuously in bulk by (1) continuously feeding to the polymerization reactor a monomer feed containing 0.01 to …
  • Syndiotactic Polystyrene
    … being fluidized by the agitator, the polymerization temperature being maintained by evaporative cooling and coolant through the reactor jacket, the recycle to the reactor being controlled by a cascade control linking the polymerization temperature control to the polymerization reactor pressure control (56500 .
  • Non-Metallocene, Single Site Catalysts
    Polymerization reactor stability problems, high costs of the metallocene cocatalysts, and difficulties experienced by film manufacturers in processing the metallocene derived polyethylene were factors discour- aging initial market acceptance and widespread commercialization.
  • Bimodal Polyethylenes
    Catalyst from S-108 is conveyed to catalyst storage vessel S-201 in Section 200, which is located near the polymerization reactors .
