ABSTRACT:
A mixture which consists of organic compounds and water and is obtained in solvent recovery by adsorption and desorption is separated by a process in which the water is removed from the said mixture (3) in an extraction column (1) by means of a highly concentrated alkali solution (4) (extracting agent), the resulting dilute alkali solution (6) (extracting agent) is then evaporated down in an evaporator (7) by means of added steam (8), the steam (9) formed in this procedure is fed to the adsorbers (2) for desorption of the organic compounds, the resulting highly concentrated alkali solution (4) is recycled to the extraction column (1), and the anhydrous organic compounds (5) are removed.
