Abstract
SE DESCRIBE UN PROCEDIMIENTO DE PRODUCCION DE PARAXILENO A PARTIR DE UNA CARGA QUE CONTIENE XILENOS EN EL QUE SE ENRIQUECE UNA PRIMERA FRACCION EN AL MENOS UN 30 % EN PESO DE PARAXILENO Y SE PURIFICA ESTA FRACCION POR AL MENOS UNA CRISTALIZACION A ALTA TEMPERATURA EN AL MENOS, UNA ZONA DE CRISTALIZACION. MAS PRECISAMENTE, SE CRISTALIZA DICHA PRIMERA FRACCION ENRIQUECIDA EN AL MENOS UN 30 % EN PESO DE PARAXILENO EN UNA ZONA DE CRISTALIZACION (50) A ALTA TEMPERATURA T1 Y VENTAJOSAMENTE ENTRE +10 Y -25 (GRADOS) C, SE RECUPERAN CRISTALES EN SUSPENSION EN UN LICOR MADRE, SE SEPARAN LOS CRISTALES DEL LICOR MADRE EN AL MENOS UNA PRIMERA ZONA DE SEPARACION (52), SE FUNDE PARCIALMENTE LOS CRISTALES OBTENIDOS EN AL MENOS UNA ZONA (55) DE FUSION PARCIAL Y SE RECUPERAN UNA SUSPENSION DE CRISTALES, SE SEPARAN Y SE LAVAN LOS CRISTALES EN SUSPENSION EN AL MENOS UNA ZONA (57) DE SEPARACION Y DE LAVADO Y SE RECUPERAN CRISTALES DE PARAXILENO PURO Y UN LICOR DE LAVADO (58), Y EVENTUALMENTE SE FUNDE (61) COMPLETAMENTE DICHOS CRISTALES Y SE RECOGE UNA CORRIENTE (60) LIQUIDA DE PARAXILENO FUNDIDO. SE PUEDE CRISTALIZAR EL LICOR MADRE EN UNA SEGUNDA ZONA DE CRISTALIZACION A ALTA TEMPERATURA T2 INFERIOR A T1 Y LOS SEGUNDOS CRISTALES PUEDEN FUNDIRSE PARCIALMENTE SE SEPARADOS Y LAVADOS COMO SE INDICA ANTERIORMENTE.
