ABSTRACT:
In an apparatus for distilling liquids an improvement is provided wherein distillate is heated within an auxiliary reboiler for further removal of volatile impurities, with the operating environment of the auxiliary reboiler being isolated from the main ambient atmosphere of the apparatus so that evaporated impurities can be vented without recontaminating the distillate or impairing the efficiency of the apparatus. Countercurrent flow of distillate and vapors within the auxiliary reboiler produces enhanced purity of the distillate.
