ABSTRACT:
A method for the recovery of heat and easily evaporable components from hot gases in which a liquid flowing downwards along heat exchanger surfaces is simultaneously heated indirectly, the hot gases are fed into the lower section of a gas space, blast gas containing evaporable components is removed at the upper section of the gas space, and a condensate derived from the hot gases is removed at the bottom of the gas space, comprising further bringing the blast gases into one or several indirect heat exchange contacts with the liquid, in successive additional gas spaces, recovering condensate accumulated at the bottoms of these additional spaces, and withdrawing the blast gases from the last additional gas space.
