Apparatus for recycling solvents containing impurities. This apparatus comprises a distillation column 1 to which there are connected: a device 2 for feeding solvent containing impurities to deliver this solvent at the bottom of the column, a device 3 for removing purified solvent, and a device for removing the impurities. According to the invention the distillation column 1 is leakproof and at the bottom comprises members 12 for heating the impure solvent so that the solvent is vapourised, at the top a condensation device connected to the device for removing the purified solvent for condensing the vapourised solvent and removing the condensed solvent, and a device for reintroducing condensed solvent which is not removed in the impure solvent, mixed with air, with a view to being intimately mixed with this impure solvent, and the apparatus includes components for automatic control of recycling and removing the impurities. <IMAGE>
