The present application is directed to a continuous contacting apparatus for separating a liquid component from a liquid mixture. The apparatus comprises: (i) an evaporation chamber ( 15 ) having first and second ends, an inlet ( 50 ) and an outlet ( 55 ) for a carrier gas, and an inlet ( 30 ) and an outlet ( 40 ) for a liquid mixture, wherein the inlet ( 30 ) for the liquid mixture and the outlet ( 55 ) of the carrier gas are located on the first end of the evaporation chamber ( 15 ); (ii) a dew-formation chamber ( 20 ) having an inlet ( 60 ) and an outlet ( 65 ) for a carrier gas and an outlet for the separable liquid component ( 80 ), wherein the inlet for the carrier gas ( 60 ) of the dew-formation chamber ( 20 ) is situated in a countercurrent manner to the inlet for the carrier gas of the evaporation chamber; (iii) a common heat transfer wall ( 10 ) providing thermal communication between the evaporation chamber ( 15 ) and the dew-formation chamber ( 20 ); (iv) a feeding device for providing the liquid mixture onto the evaporation side of the heat transfer wall; (v) an air mover for controlling a flow of a carrier gas through the chambers, wherein the gas flow in the evaporation chamber is countercurrent to the gas flow in the dew-formation chamber; and (vi) a heating apparatus for heating the carrier gas from the outlet of the evaporation chamber, wherein the heated carrier gas is directed to flow into the inlet of the dew-formation chamber. Also described is a process for separating a liquid component from a liquid mixture in a continuous contacting manner comprising employing such an apparatus for such separation.
