Xylenes Isomerization

As part of the xylenes loop of an aromatic complex, C₈ aromatics isomerization technologies recover the thermodynamic equilibrium of xylenes from PX-depleted C₈ aromatic streams produced by the PX separation unit.

Different routes for ethylbenzene valorization can be envisaged if conversion to xylenes or to benzene is preferred.
