Abstract

Las realizaciones se relacionan, en general, con métodos para el monitoreo o control de reacciones de polimerización que incluyen reacciones que producen productos poliméricos multimodales que emplean catalizadores múltiples en un reactor único. Las realizaciones presentan métodos para monitorear rápidamente y controlar las reacciones de polimerización sin necesidad de tomar muestras y analizar las propiedades del polímero. El método utiliza datos de control del reactor y datos de la existencia de material en una función matemática de indicador guía para controlar las condiciones del reactor y, de esa manera, de los productos producidos en esas condiciones. Reivindicación 1: Un método para calcular un valor de indicador guía target (LIT para controlar un reactor de polimerización y, de esa manera, controlar las propiedades de un producto polimérico producido en el mismo, propiedades que comprenden el índice de flujo (FI) determinado según el Procedimiento Bn de ASTM D1238-01 en la condición 190/21.6, que comprende: a) calcular un indicador guía target (LIT) que corresponde a un producto polimérico objetivo, donde dicho indicador guía target,(LIT) se define de la siguiente manera: LIT=(In(FIT)-A1-C´1 x FIH)/C´2; donde FIT es el índice de flujo target del polímero que se ha de producir después del ajuste de las condiciones de reacción según un nuevo indicador guía (el índice de flujo se determina de acuerdo con el Procedimiento B de ASTM D1238-01 en la condición 190/21.6 en el cual: A1=In(FIT)-C´2 x LIP-C´1 x FIHO; y donde FIO es el índice e flujo medido del polímero producido de acuerdo con el indicador guía anterior de las condiciones del reactor; donde C´1 es una constante relacionada con el sistema catalítico; donde LIP es el indicador guía calculado por una técnica de promedios exponencialmente ponderados del período de tiempo anterior para el período en el cual se determina el FIT y FIHO de las muestras, donde el LIP es un promedio móvil exponencialmente ponderado del LI, calculado con un factor de ponderación l =1-exp(-Dt/(tiempo de permanencia del polímero) sobre la base del tiempo de permanencia del polímero en el reactor, donde el cálculo es LIP = (l + LI)+(1-l)xLIT-1; donde FIHO es el índice de flujo del polímero de mayor peso molecular medido en el polímero producido de acuerdo con las condiciones del indicador guía anterior, determinado por la fórmula: FIHO = In (-0,33759 + 0,516577*In(I21.6)-0,01523*(I21.6/I21.6)); en la cual se determina el índice de flujo del polímero de peso molecular más elevado producido por el sistema catalítico bajo los parámetros actuales del reactor, estimados según los modelos que exhiben cambios del FIH basados en los cambios de las condiciones del reactor; C´2 es una constante relacionada con el sistema catalítico y b) cambiar por lo menos un parámetro del reactor a fin de ajustar el indicador guía en pos del nuevo valor de indicador guía objetivo.
