| Abstract |
Presently there are 114 explored geothermal fields in Ukraine whose waters contain free and dissolved gaseous fuel. The gas content in the thermal waters of these fields at normal conditions averages between 1-5 cub. m/ 1 cub. m water (temperature 50?C -90?C). According to preliminary estimates the power generating facilities of total of around 1200 MW thermal and 500 MW electric capacity could be constructed on the basis of there fields. The technology for utilization of geothermal field with gas-containing waters is proposed. The technology implies gas separation from the extracted waters. The separated gas is fired in power-generating units and the degassed water is fed into the geothermal heat-supply systems. The cooled thermal water is re-injected into the thermal collector. The technology has been so far realized in Ukraine on two geothermal fields, namely: Czongar (Kherson region) and Medvedevka (Republic of Crimea) in the form of experimental demonstration units. The main technical characteristics and economic factors of the units are presented in the table below. |
