A METHOD OF SEPARATING A VOLATILE COMPONENT FROM A MIXTURE UTILIZING A CARRIER GAS FOR VAPOUR TRANSPORT FROM AN EVAPORATOR TO A CONDENSOR

摘要

A volatile component (1) is separated from a mixture (2) by vaporization in an evaporator (4) and condensation in a condensor (5), vapour being transported by a carrier gas (3), circulated in and between the evaporator and the condensor. A flow (1') of a liquid (11, 1) is circulated in subsequent heat transfer steps from contact to the mixture (2), via a cooler (62), via contact to said carrier gas (3) in the condensor (5), via a heater (61) and back to said contact to the mixture (2).
