Polypropylene production simulation with cape-open interfacing of pro/ii and gPROMS

A dynamic pseudo-homogeneous model was made expressing liquid-phase homo-propylene polymerisation in a stirred reactor with reaction kinetics based on the ziegler-natta catalyst. an energy balance was made to analyse heat management in this exothermic reaction. the model was simulated using gproms process software and validated with a reference paper to ensure the model’s reliability. results of the simulation and the reference agreed with a reasonable degree of error. the method of moments was employed to predict the average molecular weights and the polydispersity and melt flow indices. meanwhile,models for the separation and treatment of the polymer formed were formulated using pro/ii software. consequently,the steady state form of model from gproms was connected by cape-open interface to pro/ii modelling environment. the flowsheet from this multi-scale modelling approach was simulated with industrial data. it is concluded,this approach enables the multi-scale plant simulation for various equipment and rigorous reactor models simultaneously,without much modelling efforts while we maintain accuracies at reduced computational cost. © school of engineering,taylor’s university
