Abstract

Seven-stage counterflow extraction of aromatic hydrocarbons from the toluene-xylene fraction of the reforming catalysate with sulfolane and its mixtures with triethylene glycol was studied. A liquid-liquid phase equilibrium diagram is presented for a pseudoternary system that includes saturated and aromatic hydrocarbons of the toluene-xylene fraction of the reformate and a mixed extractive agent composed of triethylene glycol, sulfolane, and water (48.1: 48.1: 3.8 wt %).
