Résumé :

The object of this work is to study the possibility of the hot scrubbing of industrial fumes laden with SO2 by means of the solid zone of a basic residue produced when sodium carbonate is made. Our research has shown that it is possible to attain a very high desulphurization percentage from 400°C by the sulphating of the CaO and the CaCO3 contained in the residue. The optimum temperature is around 500°C. Higher temperatures are not recommanded, since the CaSO4 starts to decompose, encouraged by the presence of the CaCl2.
