In a typical xylene loop, C8 aromatics are fractionated out of a heavy reformate C8+ aromatics stream and collected in the xylene column overhead. Then, paraxylene (PX) from the C8 aromatics stream is recovered as product—usually by an adsorption or crystallization process—in the PX recovery section.
