| Abstract | The Niland Geothermal Energy Program (NGEP) includes the engineering, procurement and construction in two phases of a net 60 MW geothermal power plant and field development of geothermal wells located near Niland, Imperial County, California. The NGEP has progressed through the conceptual, preliminary and detailed engineering phase. The assembly of the plant design into construction packages is underway. This paper is limited to discussing the process design of Phase I of the NGEP designed to initially generate a nominal net 34 MW of electric power. Geothermal fluids with an effective downhole temperature of 528°F and a TDS content of 250,000 ppm will be produced from nine production wells. The nominal well is expected to deliver approximately 350,000 lb/hr of fluid with a wellhead temperature of 391°F at a pressure of 180 psia. Steam will be produced by a modified triple flash process. The plant has been designed to minimize scale formation from dissolved silica. |
