Abstract
AbstractThe main objective of this work is the implementation of a nonlinear dynamic data reconciliation (NDDR) procedure for the in‐line monitoring of the bulk propylene polymerization, as performed in a real industrial site. Special attention is given to monitoring of the melt flow index (MI) of the polymer product obtained in an industrial extruder at different operating conditions. In order to do that, a model is developed to describe the polymerization process and the controlled degradation of polypropylene in a reactive extruder. The model is implemented in real time, allowing for in‐line and real‐time monitoring of the plant operation.
