Beschreibung
Zusammenfassung:	A process of producing PX comprising providing a C8+ feedstock, the C8+ feedstock has C8 hydrocarbons and C9+ hydrocarbons, to a crystallization unit under crystallization conditions to produce a PX enriched stream having a PX concentration of at least 99.5 wt % based on the weight of the PX enriched stream, wherein the C8+ feedstock has a PX concentration of at least 70 wt % based on total weight of xylenes in the C8+ feedstock, which the C8+ feedstock having a C9+ hydrocarbons concentration in a range from 1 wppm to 10 wt % based on the total weight of the C8+ feedstock.
