Process for reducing the content of noxious matter in dust-containing flue or process gases by means of an injection cooler as well as by the use of an adsorber in conjonction with a regenerator and of activated coke charges fed through these, whereby the gases with their dust-content prior to filtering are past through at least one injection cooler with the simultaneous addition of ammonia as an additive for the chemical binding of the large if not almost total content of the SO3 and halogen as well as for separating and precipitating the thus formed ammonia salts and heavy metals on the dust. The dust charged with the precipitated salts is withdrawn by filtering and prepared for recovery of the ammonia. After filtering of the solids contained therein the flue gases are fed through the activated coke charge(s) of the adsorber, so that essentially only SO2 is separated in the absorber, this being recovered from the activated coke by its treatment in the regenerator and being fed for further processing. |
