Influence of Process Parameters on the Gas Phase Polymerization of Ethylene: RSM or ANN Statistical Methods?

Résumé

The direct and interactive effects of process variables, including the use of iso-pentane as an inert condensing agent (ICA), on the rate of polymerization and main physical properties of linear low-density polyethylene (LLDPE) were studied using two different statistical methods. RSM based on a three level five factor Box-Behnken design (BBD) was used to generate the number of experimental runs. The generated dataset was used to develop the RSM and artificial neural network (ANN) models. The effect of the input on the dependent variables was studied using the 3D response surface of the developed RSM model. The developed models were statistically analysed and compared to determine their performance capability. The ANN model marginally outperformed the RSM model based on the computed statistical parameters but provides less information on the variable interactions.
