In fact the mission for a geothermal power plant consists of several phases. The system configuration, operational requirements for individual components, success criteria and stress on the components, can change from phase to phase. Furthermore, the duration of any phase can use deterministic or random models. All these changes and possibilities affect the system reliability. Thus, in this pap...

the south khorasan province is located in eastern iran. identifying potential geothermal zones is a pre-requisite for any thermal power plant and recreation center project. geothermal exploration involves a high degree of uncertainty and financial risk, and requires reliable exploration data to constrain development decisions. the present study focuses on identifying the potential zones of geot...

Liquid-dominated hydrothermal reservoirs, which contain saline fluids at high temperatures and pressures, have a significant potential for contamination of the environment by heavy metals. The design of the power conversion cycle in a liquid-dominated geothermal plant is a key factor in determining the impact of the installation. Reinjection of the fluid into the reservoir minimizes heavy metal...

The basis of this study is the widespread existence of low enthalpy geothermal resources in Turkey. The usage of low enthalpy geothermal resources in balneology, district heating and green house heating has made Turkey one of the primary consumer of geothermal energy in the world. However, the utilization of low enthalpy geothermal resources in geothermal-solar hybrid systems for electricity ge...

Organic Rankine Cycles (ORCs) are nowadays a valuable technology to produce electricity from low and medium temperature heat sources, e.g., in geothermal, biomass and waste heat recovery applications. Dynamic simulations can help improve the flexibility and operation of such plants, and guarantee a better economic performance. In this work, a dynamic model for a multi-pass kettle evaporator of ...

The deliverability of liquid-dominated geothermal reservoirs is presented in terms of reservoir performance, and wellbore performance. Water influx modeling is used to match the performance of Wairakei in New Zealand, arid Ahuachapan in El Salvador. The inflow performance is given in terms of a linear productivity index for liquid-only flow, and a solution-gas drive relationship for two-phase f...

Low temperature geothermal systems are an abundant energy resource in New Zealand with over 260 sites with a resource temperature of 150°C and lower. The Organic Rankine Cycle (ORC) is the standard process for low temperature energy conversion with commercial ORCs utilizing temperatures as low as 90°C, with one site at Chena, Alaska (discussed below) utilizing temperatures as low as 74°C. The a...
