Abstract
Los procesos para la recuperación de paraxileno de por lo menos dos corrientes de alimentación que contienen isómeros de xileno. El proceso incluye dirigir a una zona de recuperación de paraxileno que comprende por lo menos una zona de cristalización, una corriente de alimentación pobre en paraxileno que tiene una proporción de paraxileno con respecto al isómero de xileno total de 0.50 o menos, y también dirigir a la zona de recuperación de paraxileno, una corriente de alimentación rica en paraxileno que tiene una proporción de paraxileno con respecto a isómeros de xileno total superior a 0.50. Una corriente de producto que contiene paraxileno se recupera de la zona de recuperación de paraxileno que tiene que tiene una proporción de paraxileno con respecto a isómeros de xileno total mayor que la de la corriente de alimentación rica en paraxileno. El proceso proporciona mejoras en la eficiencia de recuperación de paraxileno y/o costo eficacia.
