A gas desulfurization scrubbing system for removing sulfur oxides from gases, such as those of fossil fuel burning operations or other manufacturing process emitting sulfur oxides, and for collecting reaction products of the desulfurization chemical reactions. A quenching section is disposed in a gas duct upstream of a gas desulfurization scrubbing tower and a scrubbing slurry is provided at that section for quenching and chemically reacting with the gas. A quench reaction product is collected, at a location between the quenching section and the scrubbing tower, for use in making commercial by- products, such as gypsum.

L'invention concerne un système d'épuration de gaz par désulfurisation permettant de retirer les oxydes de soufre de gaz tels que ceux issus d'opérations de combustion de combustibles fossiles ou d'autres procédés de fabrication émettant des oxydes de soufre, et de collecter les produits des réactions chimiques de désulfurisation. Une section de désactivation est disposée dans une conduite de gaz en amont d'une colonne d'épuration de gaz par désulfurisation et une suspension d'épuration est mise enplace au niveau de cette section pour désactiver et réagir chimiquement avec le gaz. Un produit de réaction de désactivation est collecté à un endroit situé entre la section de désactivation et la colonne d'épuration, destiné à être utilisé dans la fabrication de sous-produits commerciaux tels que le gypse.
