Abstract (en)
[origin: EP0635282A1] In the process for residue treatment in refuse incineration plants, in which, in addition to slag, hydrogen chloride arises from the flue gas scrubber, the slag after preceding mechanical comminution is washed with the crude hydrochloric acid from the wet scrubber of the flue gas purification plant. The chloride content in the slag thus treated is reduced after this by washing with water and the heavy metal chlorides in both washwaters are precipitated out by addition of soda. End products of this treatment are slag in building material quality and usable common salt. <IMAGE>
