Dynamic simulation of liquid polymerization reactors in Sheripol process for polypropylene

This work executed mathematical modelling and dynamic simulation of a polyolefin process with pre-polymerization and two loop reactors. Transient changes occurring within the reactors were simulated based on a one-dimensional plug flow assumption. Temperature control in the reactors is germane to the realization of the desired products because of the exothermic reactions, and this was accounted for using cooling jackets. The gPROMS package was utilized as a software platform for modelling and simulation.The results identified the physicochemical changes in each reactor. Molecular weight and polydispersity were predicted. Simulation results were validated with commercial data and agree well.
