ABSTRACT:
Hot reducing gases are cleaned of sulfur compounds without requiring cooling. A melt of molten lead and metal sulfide is contacted with the hot reducing gases to remove sulfur compounds such as hydrogen sulfide. The lead and elemental sulfur are regenerated from the formed lead sulfide so that the lead can be recycled in excess amounts for subsequent reaction with substantially all the sulfur compound in the hot reducing gases, while reducing the amount of formed metal sulfide slurry in the molten metal to obtain a pumpable mixture.
