Abstract

LA PRODUCCION DE PARAXILENO SE REALIZA A PARTIR DE UN REACTOR DE DISMUTACION PARASELECTIVA DE TOLUENO, EL EFLUENTE ES DESTILADO PARA ELIMINAR EL TOLUENO Y EL BENCENO EN AL MENOS DOS COLUMNAS DE DESTILACION (C1) (C2), LOS XILENOS (8) ESTAN SOMETIDOS A AL MENOS UNA CRISTALIZACION (10) ENTRE +10 Y -30 (GRADOS) C. EL LICOR MADRE (14) SEPARADO SE SOMETE EN PRESENCIA DE TOLUENO A UNA ADSORCION SOBRE TAMIZ ZEOLITICO EN LECHO MOVIL SIMULADO (15). ESTE LIBERA UN REFINADO (16) QUE CONTIENE TOLUENO EMPOBRECIDO DE PARAXILENO QUE SE DESTILA EN UNA COLUMNA DE DESTILACION (C4) Y UN EXTRACTO ENRIQUECIDO DE PARAXILENO QUE CONTIENE TOLUENO, QUE ESTA RECICLADO EN LAS COLUMNAS (C1, C2). LOS CRISTALES DE PARAXILENO ESTAN PURIFICADAS POR LAVADO CON TOLUENO Y DESTILACION O POR FUSION PARCIAL (30) SEGUIDA DE UN LAVADO POR PARAXILENO FUNDIDO DE ALTA PUREZA.
