A process for the catalytic transformation of gases containing SO2, in SO3 and/or in sulfuric acid, with purification and drying of the gases, hot intermediate absorption of SO3 formed in the first contact phase, preheating of the gases with SO2 content to be used, in thermal permutation with the hot gases containing SO3, and intermediate cooling of the hot gases containing SO3 behind the contact grids of the first contact phase, characterized in that the gases leaving the first contact phase, before entering the intermediate absorption, which is carried out at 170 to 250º C, preferably at 200º C, they are cooled in a first phase of intermediate thermal permutation in thermal permutation with the gases released from the SO3 of the intermediate absorption, and then cooled in a second phase of thermal permutation, until leaving them with a heat content that, together with the amount of heat absorbed or gases in the intermediate absorption, provide a gas outlet temperature, which corresponds approximately to the operating temperature of the intermediate absorption.
