Process for increasing xylene isomer to benzene ratio

Apparatuses and processes are provided for regulating C7 and C8 feed to an aromatics complex to increase the ratio of a selected xylene isomer to benzene ratio. Reformate may be split into three cuts in a splitter column. A side cut stream comprises predominantly C7 hydrocarbons and a bottoms steam...

Zusammenfassung:	Apparatuses and processes are provided for regulating C7 and C8 feed to an aromatics complex to increase the ratio of a selected xylene isomer to benzene ratio. Reformate may be split into three cuts in a splitter column. A side cut stream comprises predominantly C7 hydrocarbons and a bottoms steam from the splitter column comprises predominantly C8+ hydrocarbons. The relative proportion of the C7 and C8+ hydrocarbon streams sent to the aromatics complex are metered to determine the resulting ratio of a selected xylene isomer to benzene produced by the aromatics complex.
