The gases are conveyed to the lower section of the wetting reactor and further upwards to wetting zone (30). The reagent or absorbent which has reacted completely or partly is separated from the gas by a filter (22) disposed in the upper section of the reactor. Preferably a high density of particles is maintained in the wetting zone. So thick an ash layer is maintained below the gas inlet level in the lower section of the wetting reactor that the ash layer, formed of particles separated from the gas, is capable of homogenizing the wet particles and water drops falling downwards from the wetting zone.
