Software module for the simulation of the single particle growth in heterogeneous olefin polymerization

Software Module for the Simulation of the Single Particle Growth in Heterogeneous Olefin Polymerisation:

A software module was developed for the simulation of the single particle growth in heterogeneous olefin polymerisation. The mathematical model, namely the random pore polymeric flow model, was built under the Studio Fortran environment and is based on the well-known polymeric flow model as well as on the Stefan-Maxwell generalized diffusion equations.

The predictive capabilities of the single particle model were demonstrated by simulating:

(i) the effect of initial catalyst size,
(ii) the effect of the active site concentration,
(iii) the effect of catalyst morphology (e.g., extent of polymer crystallinity, etc.),
(iv) the effect of the hydrodynamic conditions on the particle polymerisation rate, particle growth and particle overheating of highly active Ziegler-Natta catalyst particles (e.g., fresh or prepolymer) in gas-phase olefin polymerisations.
