Abstract

UN SISTEMA PARA PRODUCIR UN COPOLIMERO DE POLIPROPILENO (TAL COMO UN COPOLIMERO DE PROPILENO-ETILENO) DE PROPILENO Y OTRAS ALFA-DEFINAS (TAL COMO ETILENO) PROVISTO DE DOS O MAS REACTORES EN SERIE EN DONDE AL MENOS UN REACTOR DE CORRIENTE ABAJO INCLUYA UN SISTEMA PARA CONTROLAR LA COMPOSICION DEL COPOLIMERO PRODUCIDO Y UN SISTEMA PARA CONTROLAR LA FRACCION DEL PRODUCTO TOTAL QUE ES PRODUCIDO EN EL SISTEMA DE REACCION DE CORRIENTE ABAJO. LA COMPOSICION DEL COPOLIMERO PRODUCIDO EN ESTE SISTEMA Y LA PROPORCION DEL POLIMERO TOTAL PRODUCIDO EN ESE SISTEMA DE REACCION SON CALCULADOS. LOS VALORES CALCULADOS SON COMPARADOS PARA LOCALIZAR LAS AGRUPACIONES DE PUNTOS. LOS AJUSTES A LAS PRESIONES PARCIALES DE LAS ALFA-DEFINAS SON REALIZADAS CUANDO LOS VALORES CALCULADOS NO CASAN CON LOS PREFERENTEMENTE BAJO UN COMPUTADOR DE CONTROL ESTA PREVISTO PARA DESACOPLAR LA INTERACCION DE LAS PRESIONES PARCIALES SOBRE LA COMPOSICION DE COPOLIMERO Y LA CANTIDAD DE PRODUCCION.
