PCT No. PCT/FI91/00051 Sec. 371 Date Jul. 31, 1992 Sec. 102(e) Date Jul. 31, 1992 PCT Filed Feb. 19, 1991 PCT Pub. No. WO91/12876 PCT Pub. Date Sep. 5, 1991.A method which provides purification of waste gases by adding particles of reagent and/or absorbent, which react with the pollutants in the waste gases, to the gases, and by introducing the gases into a wetting reactor for activating the reagent or absorbent contained in the gases. Gases are conveyed to at least two levels in the reactor through inlets so that a first portion of the gases is introduced into a wetting zone and a second portion of the gases below the wetting zone. A high density of particles is maintained in the wetting zone by recycling to the wetting zone particles separated from the gas above the wetting zone.
