Abstract
Se describe un procedimiento para la separacion del paraxileno con una pureza muy alta a partir de una carga de isomeros del xileno, donde el procedimiento comprende la adsorcion selectiva de una fraccion enriquecida en paraxileno; al menos una cristalizacion a temperatura elevada de esta fraccion; una isomerizacion de la fraccion empobrecida en paraxileno; se recicla el licor madre hacia la adsorcion selectiva, eventualmente vía un tratamiento con arcilla, seguido eventualmente de una destilacion del efluente tratado. El licor madre puede ser introducido en una unidad de destilacion, seguido de isomerizacion antes de ser tratado en el reactor con arcilla. La cristalizacion puede comprender varias etapas a alta temperatura, la temperatura en una de estas etapas puede ser más elevada o más baja que la de la otra etapa.
