<p>PURPOSE:To enhance recovery efficiency and heat efficiency by reducing the deterioration of each component to be recovered, by enabling the recovery a low b.p. fraction from a liquid containing a plurality of components by blowing inert gas into said liquid. CONSTITUTION:The titled apparatus is constituted of a heating mechanism 4 provided to a liquid sump part 2 in order to heat a liquid containing a plurality of components, a blowing mechanism 16, an outtake mechanism 17 of inert gas containing a low b.p. fraction, an inert gas recirculating mechanism for communicating the outtake mechanism 17 and the blowing mechanism 16 and low b.p. fraction recovery mechanisms 18, 20, 23, 24 provided in the above mentioned recirculating mechanism in order to condense the low b.p. fraction under cooling. The aforementioned mechanism 16 blows inert gas into the liquid and evaporates the low b.p. fraction along with the inert gas. By this apparatus, the low b.p. fraction is efficiently recovered in high heat efficiency without generating thermal deterioration or oxidative deterioration of each component.</p> |
