A new liquid-phase isomerization process for xylene loop debottleneck and energy savings
In a typical xylene loop, C<sub>8</sub> aromatics are fractionated out of a heavy reformate C<sub>8</sub>+ aromatics stream and collected in the xylene column overhead. Then, paraxylene (PX) from the C<sub>8</sub> aromatics stream is recovered as product—usually by an adsorption or crystallization process—in the PX recovery section.
