Abstract

Se describe un sistema de control e inferencia en línea de propiedades físicas y químicas del polipropileno y de sus copolímeros. El sistema comprendemodelos para la inferencia de propiedades físicas y químicas que no se miden en forma contínua ymod elos relevantes para controlar estas propiedades así comotambién el índice de produccion, la densidad del medio de reaccion y otras variables de interés, del proceso. El sistema de control descripto, permitemaximizr el índice de produccion asícomo t ambién, el rendimiento del catalizador en el proceso de produccion.
