Cost effective air pollution control for geothermal powerplants
Air pollution control technology developed and demonstrated at The Geysers by the Pacific Gas and Electric Company includes two different, but equally effective methods to reduce the emissions of hydrogen sulfide from geothermal power plants. These technologies may be used in other geothermal areas as well. Cost saving modifications and adaptations needed to apply these technologies in other geothermal areas with different steam composition are described. Cost estimates are presented for some typical cases. If a surface condenser gives poor H/sub 2/S partitioning with ammonia rich steam, neutralizing the ammonia with SO/sub 2/ is a cost effective alternative to secondary abatement with hydrogen peroxide. Nickel is a cost effective alternative to FeHEDTA when an oxidation catalyst is added to the cooling water of a power plant equipped with a contact condenser. 13 ref., 1 fig., 4 tabs.
