Abstract

SE DESCRIBE UN PROCEDIMIENTO DE SEPARACION DEL P A PARTIR DE UNA CARGA A TRATAR QUE CONTIENE UNA MEZCLA DE XILENOS, EN EL QUE SE HACE CIRCULAR UNA PARTE AL MENOS DE UNA CARGA QUE CONTIENE UNA MEZCLA DE XILENOS EN UNA ZONA LLAMADA DE ENRIQUECIMIENTO (14) ADAPTADA PARA ENRIQUECER UNA PRIMERA FRACCION (15) DE P CCION EN UNA ZONA DE ISOMERIZACION (19) Y SE RECUPERA UN ISOMERADO (20) QUE SE RECICLA HACIA LA ZONA DE ENRIQUECIMIENTO, SE HACE CIRCULAR AL MENOS UNA PARTE ELEGIDA EN EL GRUPO FORMADO POR LA CARGA, EL ISOMERADO Y SU MEZCLA, EN AL MENOS UNA ZONA DE HIDROGENACION SELECTIVA (3) Y EN AL MENOS UNA ZONA (8) DE TRATAMIENTO CON TIERRA. SE REALIZA UNA ETAPA DE SEPARACION (5) DEL HIDROGENO SOBRANTE EN AL MENOS UNA ZONA DE SEPARACION, ANTES O DESPUES DE DICHO TRATAMIENTO CON TIERRA, Y SE RECUPERA UN EFLUENTE QUE SE ENVIA A LA ZONA DE ENRIQUECIMIENTO (14).
