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.

Sulfolane liquid-liquid extraction of aromatics

Liquid-liquid extraction of aromatics from a refinery catalytic-reformer stream with sulfolane, after Figure 10.1 of T. Brouwer (PhD thesis, TU Twente, 2021). A countercurrent extraction cascade pulls benzene and toluene preferentially into the sulfolane-rich extract, leaving a methylcyclohexane-rich raffinate.
