Examination and thermodynamic modelling of a geothermal energy power plant for sustainable development: a case study

The new design article aims to assess the thermodynamic performance modelling of the geothermal power generation plant using real process data. This advised model comprises a steam turbine, high and low-pressure organic rankine cycles, and also these plants are working by n-butane refrigerant. Moreover, with energy and exergy efficiencies, this proposed study is compared with different refrigerants. Looking at the consequences, the ORC-1's energy and exergy efficiencies are 14.49% and 19.03%, while the ORC-2's energetic and exergetic efficiencies are 10.75% and 14.69%, respectively. Analysis results specified that the energy and exergy performances of the investigated power plant are 10.33% and 39.03%, respectively.
