Simulation in a Loop Reactor for Polypropylene

Features of a loop reactor are introduced and fluid flow is analyzed and a mathematics model is developed on the basis of the performance data in 70 kt/a polypropylene plant of Jingmen petrochemical complex. After the differential equations are solved by computer technique, the relations between the parameter profiles (such as solid content, component concentrations, temperature in the reactor, the cooling water temperature, the polymerization rate, the chain transfer rate and the catalyst deactivation rate, etc.) and the reactor length are obtained, which provides the theoretical basis for optimizing operation of PP loop reactor.
