Siliceous scaling potential of geothermal brines has long been an obstacle to the efficient energy recovery from some geothermal resources. In classical flash geosteam plant the brine for disposal was separated at high enough temperature in order to avoid ((silica oversaturation)) which might lead to scaling on hiher cooling for additional power generation through heat recovery. Recent years bi...

In this work, the study, modeling and simulation of custom designed geothermal power plant production processes are presented. A model based on the thermodynamical steam power cycles theory is developed using directed graphs, in order to consider different types of geothermal power plant structural models to be studied. The model includes steady state forms of the thermodynamical mass and energ...

Energy and exergy analyses are conducted at the Dieng Geothermal Power Plant to determine energy loss of components by calculating efficiency, rate change in flow, each component. The data were collected on component, including production wells, turbines, main condenser, inter-condensers, cooling towers, with collection occurring from April 2017 March 2018. begin enthalpy entropy both input out...

One of the major concerns of electric utilities in installing geothermal power plants is not only the longevity of the steam supply, but also the potential for changes in thermodynamic properties of the resource that might reduce the conversion efficiency of the design plant equipment. Production was initiated at Los Azufres geothermal field with wellhead generators not only to obtain electric ...

Japan is a volcanic country having abundant geothermal resources. To date, Japan has 20 geothermal power generation facilities, with a total installed capacity of 550 MW. Most of these facilities are large capacity geothermal power plants constructed by utility power companies, but due to various circumstances, there are no further plans to build large capacity plants in the near future. The Ne...

Enhanced geothermal systems (EGS) extract heat from underground hot dry rock (HDR) by first fracturing the HDR and then circulating a geofluid (typically water) into it and bringing the heated geofluid to a power plant to generate electricity. This study focuses on analysis, examination, and comparison of leading geothermal power plant configurations with a geofluid temperature from 200 to 800 ...
