文摘

In the present study a comprehensive mathematical modelis developed to simulate the dynamicbehavior of industrial poly(vinyl chloride) (PVC) batch suspensionpolymerization reactors. Morespecifically, the model predicts the monomer concentration in the gas,aqueous, and polymerphases, the overall monomer conversion, the polymerization rate andpolymer chain structuralcharacteristics (e.g., number- and weight-average molecular weights,long-chain branching, short-chain branching, and number of terminal double bonds), the reactortemperature and pressure,and the jacket inlet and outlet temperatures over the wholepolymerization cycle. Anexperimental reactor is employed to verify the theoretical modelpredictions. It is shown thatexperimental results on the time evolution of reactor temperature andpressure, the jacket inletand outlet temperature, and the final conversion and molecular weightaverages are in verygood agreement with model predictions. The predictive capabilitiesof the model are alsodemonstrated through the simulation of experimental data recentlyreported in the literature.Finally some results on the optimization of the PVC production arepresented.
