Abstract

A distillation system (1) for extracting solvent from a reservoir of solvent containing solute dissolved therein: comprising a pool (14) containing a saturated solution of the solute in the solvent coupled to the reservoir of solvent and further coupled to a pool of clean solvent (23), by a vapour bridge (10) including a conduit (12) having an open end submerged in the pool of saturated solution coupled by a closed bridge having air evacuated therefrom to a conduit having an open end submerged in the pool of clean solvent; the system including a heat exchange subsystem for pumping heat from the vapour over the column of clean solvent to the column of saturated solution.
