Abstract
A process for the removal of hydrogen sulfide from a variety of gas streams is disclosed. The gas stream containing the sour gases is contacted with a reactant solution comprising iron (Fe III) lignosulfonate. The hydrogen sulfide is converted to sulfur, and the reactant is reduced. The process may be cyclic, and may include sulfur removal and regeneration of the reactant.
