Weber, G

In the scrubbing and simultaneous oxidation of hydrogen sulfide with an aqueous alkaline scrubbing solution containing five-valent vanadium as the oxidizing agent, the sulfide is converted into higher oxidation states with simultaneous reduction of the five-valent vanadium to four-valent vanadium, the scrubbing solution subsequently is regenerated for reuse in a downstream oxidizer by treatment with an oxygen-containing gas for the reoxidation of the four-valent vanadium. To avoid losses of vanadium when the pH in the scrubbing solution is below 9.5, the vanadium is used in a ratio which exceeds the stoichiometric ratio for the oxidation of the hydrogen sulfide.
