Abstract
Water containing one or more solvents miscible in the water is heated to its boiling point. Air is introduced into the vapor mixture of steam and the miscible solvent at an air-to-steam volumetric ratio that is sufficient to get good transfer of the miscible solvent from the steam to air and provides an equilibrium temperature of the steam-air mixture compatible with operations of the heat exchanger. The mixture of gases is then rapidly cooled to condense the steam into water so that a substantial portion of the miscible solvent remains volatilized in the air. The air and condensed steam fractions are separated.
