A process for the catalytic transformation of gases with S02 content in SO3 and/or in sulfuric acid, by intermediate absorption of the SO3 formed in the first grids, preheating of the SO2 gases in thermal permutation with the produced gases containing SO3, and enrichment of its SO2 content before undergoing catalysis, by the addition of gases from the combustion of sulfur, characterized by using gases with an SO2 content of less than 9%, preferably from 3 to 9% and by which hot gases obtained in the combustion of the sulfur, are mixed with the gases of S02 behind the first thermal exchanger, before entering the contact plant, calculating the amount of sulfur in such a way, that the sum of the combustion heat of the sulfur and of the heat of oxidation of SO2 produced by the combustion of sulfur, is at least sufficient to compensate for the heat loss caused by the internal absorption day.
