Abstract

SE PRESENTA UN SISTEMA DISTRIBUIDOR (18,36) PARA DIRIGIR UNIFORMEMENTE VAPOR Y LIQUIDO A TRAVES DE LA SUPERFICIE DE UN LECHO FIJO (42) DE SOLIDOS EN UN REACTOR DE FLUJO DESCENDENTE (14). UNA PRIMERA MATRIZ DE TUBOS DESCENDENTES DE EXTREMOS ABIERTOS (33) TIENE UNA PLURALIDAD DE ELEVACIONES VERTICALMENTE SEPARADAS DE ORIFICIOS (39, 40) POR ENCIMA DEL NIVEL DE UNA CUBETA DISTRIBUIDORA (18). UNA SEGUNDA MATRIZ DE TUBOS DESCENDENTES (34) TIENE AL MENOS UNA ELEVACION DE ORIFICIOS (41) PERO NO ELEVACION DE ORIFICIOS A LA MISMA ALTURA QUE LAS ELEVACIONES MAS BAJAS DE LOS ORIFICIOS (40) EN LA PRIMERA CUBETA (33). LA AUSENCIA DE ORIFICIOS PROVOCA QUE LA VELOCIDAD DE FLUJO DEL LIQUIDO A TRAVES DE LA CUBETA DEL DISTRIBUIDOR (18) A UNA ALTURA DADA SE REDUZCA CUANDO ESA ALTURA DE LIQUIDO CAE POR DEBAJO DE LA ELEVACION DE LOS ORIFICIOS (39) SECUNDARIOS DESDE EL FONDO EN LA PRIMERA MATRIZ (33).
