Abstract
Procédé de séparation de dioxyde de soufre et éventuellement de sulfure d'hydrogène ainsi que d'oxydes nitriques de gaz d'échappement au moyen de sulfures dans une phase liquide de manière à récupérer le soufre sous la forme de soufre élémentaire fondu, les sulfates solubles formés lors de l'épuration étant régénérés au moyen de sulfures ou par réduction à nouveau en sulfures et ramenés vers le stade d'absorption du dioxyde de soufre.
