Waste gas is esp. divided into 2 streams and a first stream injected downwardly into the absorption chamber of a reactor. Aq. liq. (8) contg. an absorbent is atomised and fed into the stream to adsorb sulphur oxides and evaporate part of the H2O content of the atomised liq. to produce a particulate contg. 3 wt.% moisture at least. Second stream is fed to the bottom of the chamber to dry, fluidise and maintain a layer of particles received from the upper section. - Desulphurised gas and spent absorbent particles are withdrawn from the reactor. Reactor esp. has a chamber with a downward tapering lower portion, a rotary atomiser in the chamber roof, an air disperser surrounding the atomiser to eject waste gas around the atomiser, a fluid bed assembly and gas and particle withdrawing ducts.
