Abstract

SE DESCRIBE UN PROCEDIMIENTO DE SEPARACION DE PARAXILENO EN LECHO MOVIL SIMULADO A PARTIR DE UNA CARGA DE C8 QUE COMPRENDE UNA ETAPA DE ADSORCION EN UNA ZEOLITA Y DE DESORCION POR UN AGENTE DE DESORCION QUE LIBERA UN EXTRACTO Y UN REFINADO Y UNA ETAPA DE CRISTALIZACION DEL EXTRACTO. SE INTRODUCE UN CAUDAL DE AGUA EN LA CARGA, EN EL AGENTE DE DESORCION Y/O EN UNA CORRIENTE DE RECICLADO DE UN FLUJO EN LA COLUMNA, DE MANERA QUE LA MEDIA PONDERADA DE LOS CONTENIDOS DE AGUA MEDIDA EN EL EXTRACTO Y EN EL REFINADO ESTE COMPRENDIDA ENTRE 1 Y 200 PPM. LA RELACION S/F DEL CAUDAL DE AGENTE DE DESORCION RESPECTO DEL DE LA CARGA DURANTE LA ETAPA DE ADSORCION Y DE DESORCION ESTA COMPRENDIDO ENTRE 0,6 Y 2,5.
