Sulfolane extractive distillation of aromatics

Extractive distillation recovering benzene and toluene from a stabilized reformate's C6-C7 non-aromatics (represented by methylcyclohexane) using sulfolane, after Figure 10.2/10.6 of T. Brouwer (PhD thesis, TU Twente, 2021). A vacuum solvent-recovery column then splits the aromatics from the sulfolane (reported as its own product rather than recycled). Note: the extractive column (ED) does not fully converge within the solver's iteration cap for this 4-component polar/nonpolar system and returns a partial profile — shown for the process topology rather than as a converged reference case.

Reformate splitter

A single column cutting catalytic reformate into a light benzene/hexane overhead and a toluene/xylene bottoms — the IECR 50, 5680 configuration from the ChemSep casebook.

Reformate splitter via dividing-wall column

A refinery catalytic-reformer stream (benzene/toluene/o-xylene plus a non-aromatic n-heptane proxy) is split into three purified aromatics cuts by a single thermally-coupled dividing-wall column instead of two ordinary columns in series — the same DWC economics as the BTX example, applied to a genuine reformate splitter duty.
