Abstract
An uncondensed gas in steam discharged from a turbine in a geothermal power plant and separated from water with a condenser is treated by a desulfurization method comprising the combustion step of combusting the uncondensed gas in the steam to convert hydrogen sulfide in the uncondensed gas to a sulfurous acid gas and the absorption reaction step of bringing a combustion gas coming from the combustion step into gas-liquid contact with an absorbent slurry and further bringing air into air-liquid contact with the absorbent slurry to allow the absorbent slurry to absorb the sulfurous acid gas and undergo oxidation and neutralization to exhaust desulfurized gas and to convert the absorbent slurry to a sulfate slurry, whereby detrimental hydrogen sulfide is removed from the steam exhausted after the use of the steam for power generation in the geothermal power plant.
