ABSTRACT:
In the method and device for separation of harmful substances from a flue gas, in an absorption-heat exchanger arrangement both washing and also cooling of the flue gas is carried out, the flue gas being cooled below the dew point and this cooling process taking place by means of exterior air in counter flow. The flue gas is divided during its passage through the heat exchanger into at least two parallel part flows of which the first part flow is directed into a first treatment zone and the second part flow is directed into a second treatment zone. The two treatment zones are connected parallel to one another. In the first treatment zone a first absorption liquid is introduced into the flue gas which effects extensive removal of harmful substances from the flue gas, while in the second treatment zone a second absorption liquid is introduced into the flue gas, in which second absorption liquid precipitated harmful substances are soluble, to clean equipment surfaces. These two treatment zones are cyclically exchanged.
