Abstract

PROCEDIMIENDO DE PRODUCCION DE PARAXILENO DE GRAN PUREZA A PARTIR DE UNA CARGA QUE CONTIENE UNA MEZCLA DE HIDROCARBUROS AROMATICOS DE 7 A 9 ATOMOS DE CARBONO EN EL QUE SE HACE CIRCULAR UNA PARTE AL MENOS DE LA CARGA EN UNA ZONA ADAPTADA PARA ENRIQUECER UNA PRIMERA FRACCION DE PARAXILENO Y SE PURIFICA AL MENOS UNA PARTE DE ESTA PRIMERA FRACCION MEDIANTE AL MENOS UNA CRISTALIZACION A ALTA TEMPERATURA EN AL MENOS UNA ZONA DE CRISTALIZACION. EL PROCEDIMIENTO SE CARACTERIZA PORQUE SE CRISTALIZA DICHA PRIMERA FRACCION ENRIQUECIDA CON PARAXILENO EN UNA ZONA DE CRISTALIZACION QUE COMPRENDE AL MENOS DOS ETAPAS (50,70) DE CRISTALIZACION A ALTA TEMPERATURA, Y PREFERIBLEMENTE ENTRE +10 Y -25 (GRADOS) C. LA ZONA DE ENRIQUECIMIENTO CON PARAXILENO PUEDE SER UNA CRISTALIZACION A MUY BAJA TEMPERATURA, UNA ADSORCION SELECTIVA O UNA ZONA DE DISMUTACION DE TOLUENO.
