ABSTRACT:
The present invention relates to a process for reducing the content of gaseous acid pollutants soluble in water and contained in fumes discharged from an incineration plant, in the course of which the said fumes are cooled by means of indirect heat exchange with a cold fluid, thus producing a condensate containing acid pollutants, and in which, after this cooling stage, the said fumes still containing acid pollutants are washed using the condensate as washing liquid.
