Abstract: IN AN ISOMERIZATION ZONE, C8 AROMATICS ARE CONVERTED INTO XYLENE ISOMERS AND NAPHTHENES. CONVENTIONAL ISOMERIZATION TECHNIQUES ARE USED TO PRODUCE THE XYLENES AND NAPHTHENES, AND CONVENTIONAL FRACTIONAL CRYSTALLIZATION TECHNIQUES ARE THEN USED TO SEPARATE PARAXYLENE FROM OTHER ISOMERS OF XYLENES. THE DISTINGUISHING FEATURE OF MY INVENTION IS THE SEPARATION OF THE XYLENES FROM THE NAPH-
THENES BEFORE CRYSTALLIZATION AND THEN RECYCLING THE NAPHTHENES TO THE ISOMERIZATION ZONE.
