ABSTRACT:
SO.sub.2 is absorbed from hot flue gas by spray drying a Ca(OH).sub.2 -containing suspension in the flue gas. Fly ash is left in the flue gas which is to be treated in the spray absorption process, and the powder which is produced by the spray absorption process and which consequently contains the fly ash and partly reacted Ca(OH).sub.2 is partially recycled. Operation is controlled to obtain a temperature of the flue gas after the treatment which is 8.degree.-20.degree. C. above the saturation temperature of the flue gas at this stage. The process leads to optimum use of the Ca(OH).sub.2 used as absorbent and of the neutralization power inherent in the fly ash. Problems due to sedimentation of the absorbant before its atomization are avoided.
