During a method for fractional condensation of acid combustion gas components in condensers, by the addition of a peroxide solution to a suitable quantity of excess air, it is possible to avoid the disadvantages of the previously known methods. Exploitation of the latent heat energy of the combustion gasses is thus possible as the purification products become economical through a price reduction of the waste gas purification, resulting also in a reduced strain on the environment and the atmosphere. It should be possible to utilize the combustion gas after purification. In order to attain these ends a dispersed, surface-increasing filter aid suspended in the peroxide solution at a temperature of approx. 220 DEG C is added before the combustion gas enters the condenser, with the subsequent reduction of temperature in the condenser by the oxidized combustion gas to the temperature interval of 160 DEG C-140 DEG C, draining H2SO4, and to the temperature interval of 120 DEG C-110 DEG C, draining HNO3, and further to approx. 20 DEG C where other residual products condense. |
