Environmental effects of selected chemical and physical geothermometers at Olkaria geothermal power plant

Abstract

To evaluate environmental implications of the geothermal power plant at Olkaria Kenya. fluid samples ,vere collected (it Olkaria power stations (l and 2) and Olkaria wells 908 and 701. They ,I'ere analyzed for; Cl,H]S, COl, CH~, O2, H2, N, SO·]~,Band F. The pH was also taken. A UV/VIS spectrophotometer, ion-selective. electrode, gas chromatograph, titroprocessor, pH- meter; and a' Weber separator were used for analysis. The levels of these geothermometers werefound to be very low. The pH at the wells was observed to be basic while at the stations, acidic. In conclusion, no significant negative environmental effects were observed
