Abstract

A multi-stage catalytic oxidation process from sulfur dioxide to sulfuric anhydride, using at least one intermediate absorption stage of the formed sulfuric anhydride, characterized by the injection of a hot and dry gas into the sulfuric anhydride-depleted gas resulting from the stage absorption.
