Abstract
PROCEDIMIENTO PARA LA PRODUCCION CONTINUA DE POLIMEROS DE ETILENO. CONSTA DE LAS SIGUIENTES ETAPAS: 1. SEPARACION DE LOS POLIMEROS FORMADOS POR LA MEZCLA REACCIONAL EN UNA PRIMERA ZONA DE SEPARACION MANTENIDA A UNA PRESION COMPRENDIDA ENTRE 100 Y 500 BARES. 2. SEPARACION DE LOS POLIMEROS ANTERIORMENTE SEPARADOS DE LOS GASES RESIDUALES, EN UNA SEGUNDA ZONA DE SEPARACION, MANTENIDA A UNA PRESION COMPRENDIDA ENTRE 1 A 1,5 BARES. EXISTE UNA ETAPA INTERMEDIA DE SEPARACION DE LOS GASES RESIDUALES DE LOS POLIMEROS SEPARADOS EN LA SEGUNDA ETAPA, REALIZANDOSE DICHA ETAPA EN UNA ZONA INTERMEDIA MANTENIDA A UNA PRESION DE 10 A 70 BARES, SIENDO ENVIADOS A CONTINUACION HACIA UNA SEGUNDA ZONA LOS POLIMEROS SEPARADOS EN ESTA ZONA INTERMEDIA, MIENTRAS QUE LOS GASES RESIDUALES SEPARADOS EN ESTA ZONA INTERMEDIA SE MEZCLAN CON EL FLUJO DE ALIMENTACION DE ETILENO Y SE COMPRIME HASTA ALCANZAR LA PRIMERA ZONA DE SEPARACION.
