| Abstract: | On Milos island, where a high enthalpy gecthermal field capable:of producing high salinity fluids has been discovered a 2MW Pilot plant was installed. Systematic production tests have been carried out at the production well, with emphasis on geothermal fluid chemistry and behaviour. During successive long term operation trials of the Unit (turbogenerator, steam gathering and brine transmission system), problems arose in both steam and brine cycles due to severe scaling phenomena encountered. The sequence of events in identifying the scaling problems and the technical approaches applied to remedy them, are reported in this paper together with data concerning the plant's operational problems and with the direct hot reinjection used as brine disposal method. |
