Abstract
Abstract Apparatus for producing power and desalinated water from geothermal fluid according to the present invention comprises: a geothermal power plant that produces power from geothermal fluid supplied thereto; means for supplying sea water to the condenser of said geothermal power plant that produces heated sea water; and a desalination plant to which the heated sea water is supplied and which produces drinking water. Preferably, the geothermal power plant that produces power comprises an organic Rankine cycle geothermal power plant that produces power. Alternatively, the geothermal power plant that produces power comprises an organic combined cycle Rankine cycle geothermal power plant that produces power. In a further alternative, the geothermal power plant that produces power comprises a closed cycle steam geothermal power plant that produces power. In a still further alternative, the geothermal power plant that produces power comprises an ammonia cycle geothermal power plant that produces power. As far as the desalination plant is concerned, the desalination plant preferably comprises a multi-flash desalination plant. In an alternative, the desalination plant comprises a reverse osmosis desalination plant.
