Abstract
A process and apparatus for the production of at least one xylene isomer is provided. The process includes passing a first stream to one side of a split shell fractionation column and a second stream to the other side of the column. The second stream has a higher ratio of ethylbenzene to total Caromatics than the first stream. A first overhead stream from the one side is separated and passed as a mixed xylene product and a second overhead stream from the other side is separated and passed as feed to a para-xylene separation zone.
