Purifying geothermal steam

Patent ·
OSTI ID:6152558

Residual geothermal steam containing hydrogen sulfide from a steam turbine is condensed with an aqueous solution of ferric chelate in a direct or indirect condensor 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.
