| Abstract: | A polypropylene MFR soft measurement model during the polymerization is built using both mechanistic and statistical methods.According to polymerization mechanism and reaction dynamics,a mechanistic model of propylene polymerization is developed.Neural networks/partial least squares(NNPLS)method is used in statistical model.The application shows that the calculation speed and accuracy of model can satisfy the practical need.The model has been successfully applied to a plant to give the operators guidance. |
