  • Electrolytic reduction of sulfidic spent alkali metal wastes
    Patent number: 4246079
    Abstract: A process for reducing the sulfur concentration in a fluid, such as a hydrocarbon gas stream is disclosed. The process comprises contacting the fluid with an aqueous alkali metal hydroxide solution and subsequently contacting the resulting liquid effluent with carbon dioxide to form an aqueous alkali metal carbonate salt solution and a volatile sulfur compound. The aqueous alkali metal carbonate salt solution is passed into an electrolytic cell wherein the alkali metal salt is converted to alkali metal hydroxide.
