Claim:
1. Apparatus for producing para-xylene, the apparatus comprising: (a) a catalytic reformer for producing a reformate stream comprising C (b) a first separation system for separating the reformate stream into at least a toluene-containing stream, a C (c) a toluene methylation unit for converting toluene in the toluene-containing stream to xylenes and produce a methylated effluent stream; (d) a transalkylation unit for converting C (e) a second separation system for recovering para-xylene from the C (f) a liquid phase xylene isomerization unit for isomerizing xylenes in the at least one para-xylene depleted stream to produce a first isomerized stream; (g) a first recycle system for recycling at least part of the first isomerized stream to the second separation system; and (h) a second recycle system for recycling at least part of the transalkylation effluent stream to the toluene methylation unit and second separation system.
