Abstract
SE DESCRIBE UN PROCESO Y UN DISPOSITIVO QUE PERMITE PRODUCIR Y SEPARAR CONTINUAMENTE PARAXILENO DE GRAN PUREZA A PARTIR DE UNA CARGA DE HIDROCARBUROS EN C8 AROMATICA. SE UTILIZA EN COMBINACION SUCESIVAMENTE: 1) UNA ETAPA DE SEPARACION DE PARAXILENO DE BAJA PUREZA (75 A 98%) POR CROMATOGRAFIA DE ADSORCION EN LECHO MOVIL SIMULADO, CON UNA RELACION DE CAUDALES DE SOLVENTE SOBRE CARGA DE 1,2 A 2,5; 2) UNA ETAPA DE PURIFICACION Y DE LAVADO DEL PARAXILENO DE BAJA PUREZA MEDIANTE LA FASE RECRISTALIZACION (-25 A +10 (GRADOS) C) DE LOS PROCESOS CLASICOS DE PRODUCCION DEL PARAXILENO POR CRISTALIZACION, EVITANDO ASI UNA PRIMERA FASE DE ESTOS PROCESOS PARTICULARMENTE COSTOSOS EN ENERGIA; 3) UNA ETAPA DE ISOMERIZACION CATALITICA DE LA FRACCION DE LA CARGA AGOTADA DE PARAXILENO POR LA ETAPA DE SEPARACION Y SE RECUPERA UN ISOMERATO QUE SE RECICLA. EL SOLVENTE DE DESORCION EN LA ETAPA (1) Y DE LAVADO EN LA ETAPA (2) ES VENTAJOSAMENTE TOLUENO.
