Abstract
UN METODO PARA DETENER, BAJO CONDICIONES DE EMERGENCIA, UNA REACCION DE POLIMERIZACION DE OLEFINA EN PRESENCIA DE UN CATALIZADOR BASADO EN UN METAL DE TRANSICION EN UN REACTOR DE FASE GASEOSA, QUE SE INTRODUCE A DICHO REACTOR UNA CORRIENTE DE ALIMENTACION DE MONOMERO, SE DESCARGA DE DICHO REACTOR UN GAS DE RECICLAJE COMPUESTO DE MONOMERO, COMONOMERO, HIDROGENO Y DILUYENTES Y SE LO DIRIGE A TRAVES DE UN CIRCULADOR Y DE POR LO MENOS UN INTERCAMBIADOR DE CALOR, Y DEVOLVIENDO LUEGO EL GAS ENFRIADO AL REACTOR, LA MEJORA EN EL METODO CONSISTE EN INTRODUCIR UN GAS VENENO EN EL REACTORPARA DETENER LA REACCION, DIRIGIENDO POR LO MENOS UNA PARTE DEL GAS DE RECICLAJE O LA CORRIENTE DE ALIMENTACION, A TRAVES DE UN MECANISMO IMPULSOR AUXILIAR ASOCIADO AL CIRCULADOR, PARA MANTENER LA OPERACION DE DICHO CIRCULADOR A UN NIVEL PARA MANTENER CONDICIONES FLUIDIZADAS EN DICHO REACTOR.
