Abstract

L'invention concerne un procédé de purification de gaz résiduaires industriels renfermant en faibles concentrations H2 S, SO2 , CS2 , COS, ou éventuellement de la vapeur de soufre, ainsi que d'importantes quantités de H2 O, CO 2 et N2 dans lequel les gaz résiduaires sont tout d'abord soumis à une réduction catalytique après laquelle tous les composés du soufre sont transformés en H2 S, et sont enfin lavés par une solution aqueuse d'amine avant d'être incinérés et rejetés à l'atmosphère tandis que l'amine est régénérée par chauffage et les gaz dégagés constitués d'H2 S et de CO2 sont retournés à une unité de fabrication de soufre. Ce procédé est caractérisé en ce que la température des gaz à traiter est en permanence maintenue à une valeur supérieure au point de rosée de l'eau contenue dans ces gaz en tous les points de l'installation.
