Book excerpt: Environmental control technologies are essential elements to be included in the overall design of Imperial Valley geothermal power systems. Environmental controls applicable to abatement of hydrogen sulfide emissions, cooling tower drift, noise, liquid and solid wastes, and induced subsidence and seismicity are assessed here. For optimum abatement of H2S under a variety of plant operating conditions, removal of H2S upstream of the steam turbine is recommended. The environmental impact of cooling tower drift will be closely tied to the quality of cooling water supplies. Conventional noise abatement procedures can be applied and no special research and development are needed. Injection technology constitutes the primary and most essential environmental control and liquid waste disposal technology for Imperial Velley geothermal operations. Subsurface injection of fluids is the primary control for managing induced subsidence. Careful maintenance of injection pressure is expected to control induced seismicity. (MHR).
