Abstract

A combination solvent extn-steam distn. process for aromatic hydrocarbons recovery is improved by: (a) introducing high pressure steam to a steam ejector (b) passing the steam obtd. to a heat exchange, where it is condensed by heat exchange with cooler lean solvent coming from the bottom of a distn. column; (c) returning the lean solvent from (b) to the bottom of the distn. column; (d) passing part of the condensate from (b) to a heat exchanger, where it is vaporised by heat exchange with the warmer lean solvent from the bottom of the distn. column; and (e) passing the vapour from (d) to the steam ejector.
