A model is developed for an existing organic Rankine cycle (ORC) utilizing a low-temperature geothermal brine including the performance characteristics of the components. The model is validated with a set of 7200 operation data collected in one-year. The operation of the ORC is optimized...

The University of Debrecen, Faculty of Engineering, has been conducting a research program in geothermal energy since 2008. This program enabled me to devise an analytical study of the monetary and non-monetary criteria of geothermal projects. The monetary criteria of a region or a location for...

Hazánk kedvező geológiai viszonyainak köszönhetően a geotermikus energia hasznosítására adottak a feltételek. A geotermikus energia felhasználása az 1960-as évektől lendült fel. Az addigi kitermelés kizárólag egészségügyi és gyógyászati célokat szolgált, ezután jelent...

It is well known that rooftop solar thermal panels increase both power rates of circulation pumps and initial investment cost of solar assisted ground source (geothermal) systems. To avoid both of them it means that the unnecessary energy consumption rates of circulation pump(s) and their...

Natural gas stream must be preheated before pressure reduction takes place at natural gas pressure drop station (CGS). It ensures that the natural gas stream remains above hydrate-formation zone. The heater which is employed to provide the required heat consumes a huge amount of fuel. In this...

The concept of \"sustainable development\" and the necessity for its realization has gone a long way in order to be unanimously accepted. Over time many authors have written about the problem regarding resources depletion, about the effects of pollution and their economic, ecological and social...
