<p>An evaporation and distillation apparatus for recovering a low-boiling-point fraction of distillate from a liquid containing a plurality of components comprises a heating mechanism to heat the liquid, a blowing mechanism for blowing an inert gas into the liquid and evaporating a low-boiling-point fraction together with the inert gas, an inert gas withdrawal mechanism arranged in the upper portion of the apparatus to withdraw the inert gas containing the low-boiling-point fraction, an insert gas circulating mechanism arranged to connect the inert gas withdrawal mechanism, and a low-boiling-point fraction recovery mechanism arranged in the circulating mechanism to cool and condense the low-boiling-point fraction. <IMAGE></p> |
