Abstract

Se describe un procedimiento para la produccion de polietileno de alta densidad (HDPE) o polietileno lineal de baja densidad (LLDPE) en reactores de fasegaseosa, aislados o combinados, usando catalizadores de cromo o de Ziegler-Natta, provistos con e l control en línea de ciertas variables de procedimientos comoasí también propiedades físicas de la resina producida. Dicho procedimiento comprende el uso de modelos para la inferencia de las propiedades físicas yvariables de procedimiento no medidas continuamente, además de modelos relevantes para el control de dichas propiedades y condiciones operativas delprocedimiento. El control de las variables del procedimiento provee además la maximizacion del ritmo de produccion y productividad del cata lizador en lareaccion de polimerizacion.
