Abstract

LA OPERACION DE UN PROCESO FCC SE PERFECCIONA MEDIANTE EL USO DE UNA NUEVA CONFIGURACION DE DESACOPLADOR DEL ELEVADOR DE REACTOR NUCLEAR, QUE RESULTA EN CATALIZADOR ESTANDO SUSPENDIDO EN UNA ZONA DE DESACOPLAMIENTO EN UNA SECCION 29 DEL ELEVADOR, PROXIMA O POR ENCIMA DE LAS ENTRADAS 34 DE CICLON DEL ELEVADOR, COMO UNA CONSECUENCIA DE VAPORES, Y CATALIZADOR QUE SALE DEL ELEVADOR A TRAVES DE LAS ENTRADAS DE CICLON, PARA OBTENER UNA DENSIDAD CATALIZADORA SUSPENDIDA, QUE ES SUPERIOR A LA DENSIDAD CATALIZADORA FLUYENTE MAS ABAJO EN EL ELEVADOR. EL CATALIZADOR SUSPENDIDO PROPORCIONA UNA ZONA DE DESACOPLAMIENTO QUE REFUERZA LA SEPARACION DEL CATALIZADOR DE LOS VAPORES DEL PRODUCTO. EL ELEVADOR 22, 26, 29 OPERA EN CONDICIONES QUE EVITAN TODA DESCARGA IMPORTANTE DEL VAPOR DEL PRODUCTO PROCEDENTE DE SU EXTREMO 40 SUPERIOR. LA DISPOSICION PROPORCIONA ADEMAS UN METODO CONVENIENTE PARA AIREAR VAPORES DE DESPRENDIMIENTO, INTRODUCIDOS EN 26, Y QUE SALEN POR EL SISTEMA DE CICLON DEL REACTOR 34, 36, 42, 44.
