Abstract
Processes and apparatuses for producing a Caromatic isomer product are provided. The processes comprise introducing a raffinate product stream comprising Caromatic isomers to an isomerization unit to provide an isomerized stream. The isomerized stream is separated to provide a first stream comprising Cnaphthenes and Caromatic hydrocarbons and a second stream comprising Caromatic isomers. The first stream is passed to an extractive distillation column to provide a recycle feedstream comprising the Cnaphthenes and an extract stream comprising the Caromatic hydrocarbons. The recycle feedstream is passed to the isomerization unit.
