ABSTRACT:
This invention is a crystallization process for p-xylene recovery. A single temperature crystallization production stage is used for producing p-xylene from a feed having an above equilibrium p-xylene concentration, such as from a toluene disproportionation process. Scavenger stages are also used to raise the p-xylene recovery rate.
