Abstract
A liquid concentrator having a guide rod (1) around which solution flows, in a chamber (2). A heat source (3) surrounds the guide rod. The solution is preferably mixed with an exchange solvent, the exchange solvent having a higher boiling point than the solution solvents. As the mixture flows down the guide rod, the original solvents are preferably evaporated, concentrating the materials of interest, and leaving the effluent relatively more concentrated in the exchange solvent.
