Abstract
A method for recovering a water soluble solvent contained in a raffinate stream produced by an aromatic compound extraction process, comprising: (a) mixing said raffinate stream with a first aqueous stream, in a high turbulence conditioning zone ; (b) passing the effluent resulting from the conditioning zone to a water extraction zone, and extracting said solvent from said effluent therein, with a second aqueous stream; and (c) recovering from said extraction zone a stream of aqueous extract, containing said solvent, and a refining stream substantially free of said solvent.
