Effect of Non-Condensable Gases on geothermal power plant performance. Case study: Kizildere Geothermal Power Plant-Turkey
Non-Condensable Gases (NCGs) are natural components of geothermal fluids, and they are a source of considerable capital and operating costs for power plants. The NCG content of geothermal steam varies over the world from almost zero to as much as 25% (wt). In this work, the influence of NCGs on the thermodynamic performance of geothermal power plants is analysed for various NCG content and ...

Exergy analysis and performance evaluation of Kizildere Geothermal Power Plant, Turkey
Conventional geothermal power plants (GPP) differ from fossil-fuel power plants (FFPP) in many ways. The most specific ones are that GPPs are not cyclic plants and the working fluid is not pure steam. Geothermal steam contains non-condensable gases (NCG) which degrade power plant efficiency. This discrepancy leads to two considerations in energy and exergy analysis of GPPs. One is that the amount ...

Case Study - Aluto Langano Power Plant Rehabilitation
Aluto Langano, Ethiopia – 2007 The Aluto Langano Geothermal Pilot Plant (ALGPP) is located on the Aluto volcanic complex of the Ethiopian Rift valley, close to the eastern escarpment between Lake Langano and Lake Ziway, some 200 km southeast of Addis Ababa. The Aluto volcanic complex is a young acidic system consisting of domes, lava, and pyroclastic interbeds. The geothermal field was ...

Artificial geothermal energy potential of steam-flooded heavy oil reservoirs
This paper explores the concept of harnessing geothermal energy from heavy oil fields that have undergone steam flooding and so accumulated substantial heat from steam injection. Once the steam flooding process reaches economic cut-off resulting from high water cut and/or high steam-to-oil ratio, the reservoir would be abandoned, leaving behind stored energy in the form of heat. From this point, ...

Case Study - 2.0 MW Nominal Geothermal Power Plant
Lake Naivasha, Kenya – 2007 Under a contract signed in June 2006 with Oserian, Geothermal Development Associates (GDA) agreed to design, manufacture, inspect, test, pack, and ship a 2 MW nominal geothermal steam turbine generator and related power plant auxiliary components from Reno, Nevada, USA to the Oserian flower-growing facility near Lake Naivasha, Kenya. GDA will provide technical ...

Cultivating geothermal energy sources – Case Study
Since the early twentieth century, geothermal energy has been used to produce electricity. In the 1980’s and 90’s, rapid expansion in the demand for geothermal energy put pressure on suppliers to reduce costs and increase efficiencies. Because of high temperatures and varying pressures, measuring steam flow through "Differential Pressure" methods was fraught with inconsistencies. ...

Geothermal plant protects pumps - case study
This large geothermal company needed reliable equipment in the deserts of southeastern California. Geothermal plants turn water into to steam to drive turbines. Protecting the pumps is paramount. Keeping the inflowing water clean of debris and marine life, an IWS traveling water screen provides reliable removal with minimal labor. Debris is lifted from the water, and dropped directly into a ...
