Abstract

1. Semi-dry process for eliminating acid pollutants contained in fumes, in particular sulphurous anhydride, by a basic pulverulent treatment product of the type in which the said fumes are brought into close contact with the said product, in order that the latter absorbs the pollutants contained in the fumes by chemical reaction after which separation takes place between the gases treated and the product used in the treatment, the purified gases then being capable of being discharged into the atmosphere, characterised in that a quantity of water comprised between about 5 and 15% of the weight of the dry product is added to the dry product, i.e. a quantity of water small enough to keep the product in powder form, before suspending it in a rising stream of the said fumes, carried out in a reaction and drying column.
