OSTI ID:5247421
Residual geothermal steam containing hydrogen sulfide from a steam turbine is condensed with an aqueous solution of ferric chelate whereby the hydrogen sulfide is converted to free sulfur and the ferric chelate is converted to ferrous chelate. The ferrous chelate is subsequently oxidized back to the ferric state and reused.
