Power generation from low enthalpy geothermal fields by design and selection of efficient working fluids for organic rankine cycles Conference Paper uri icon

abstract

  • The efficient power generation from low enthalpy geothermal fields through design and selection of working fluids for organic Rankine cycle (ORC) processes was examined using a systematic methodology based on the design of optimum working fluid candidates using a computer aided molecular design method. The process performance of the working fluids was evaluated using ORC process simulations. A suitable performance index was developed to allow consideration of variable heat source conditions for the ORC process. The proposed approach was illustrated via a case study involving low-enthalpy geothermal fields with a broad range of representative temperature and flowrate characteristics. The results highlighted useful performance trade-offs among the considered working fluids under various geothermal field conditions. This is an abstract of a paper presented at the 7th European Congress of Chemical Engineering-7 and the 19th International Congress of Chemical and Process Engineering CHISA (Prague, Czech Republic 8/28/2010-9/1/2010).
