<p>The process for treating flue gases prior to their release into the atmosphere comprises dedusting, cooling by heat exchange with a heat exchange medium to room temperature and separating off gaseous pollutants by precipitation onto bodies of large surface area over which the flue gases are passed. The heat exchange medium evaporates during heat exchange and is then used as a working medium by a machine. To separate off the gaseous pollutants, the flue gases are passed in a compressed state through regenerators which have a temperature drop to below the condensation point of the gaseous pollutants. After leaving the coolers, the gases are further cooled by expansion and are passed in counter-current over the coolers to precool them and the gases are reheated to ambient temperature during this. This process allows a complete removal of pollutants with the furthest possible utilisation of the total heat content of the flue gases and thus economically.</p> |
