Abstract

UNA ESTRUCTURA DE DESTILACION CATALITICA EN FORMA DE FARDO FORMADA A BASE DE COLOCAR MULTIPLES ESTRUCTURAS EN FORMA DE ESLABONES O DE TUBOS CONTINUOS (22,24) SOBRE LA PARTE SUPERIOR DE UNA PANTALLA DE MALLA DE ALAMBRE, TAL COMO UN ALAMBRE ELIMINADOR DEL VAHO (16), DISPUESTO FORMANDO UN ANGULO RESPECTO AL EJE LONGITUDINAL DEL FARDO, DE TAL MODO QUE CUANDO LA PANTALLA DE MALLA DE ALAMBRE SE ENROLLA, LA ESTRUCTURA ENROLLADA FORMA UNA ESTRUCTURA DE DESTILACION CATALITICA NUEVA Y MEJORADA. EL TUBO CONSTA DE UN ELEMENTO TUBULAR DE MALLA ABIERTO SEMIRRIGIDO, FLEXIBLE (10) RELLENO CON UN MATERIAL CATALITICO EN PARTICULAS (14), EN DONDE LA ESTRUCTURA EN FORMA DE TUBO TIENE UN FIADOR (12) CADA 1-12 PULGADAS A LO LARGO PARA FORMAR UN ESLABON MULTIPLE (22,24).
