Modelling of the liquid phase polymerization of olefins in loop reactors

Abstract In this work a new model for the polymerization of olefins in a loop reactor is presented. The reactor is modelled as two tubular reactors interconnected. In contrast to the traditional equivalent CSTR approach, this model allows important effects such as recycle rate, axial dispersion and heat transfer to be investigated. Some simulation results are presented.
