  • Evaluation of a process simulator for modelling and analysis of Rankine cycle steam power plants

    Applicability of the HYSYS process simulation package to thermodynamic modelling and analysis of Rankine cycle steam power plants, using first and second law analyses, has been evaluated. Theoretical Rankine cycles, and more realistic cycles based on power plants modelled in other studies, were simulated. Energy, exergy and efficiency values determined from the simulations were compared to those ...

  • Comparative exergy analysis of ammonia–water based Rankine cycles with and without regeneration

    Power generation systems using an ammonia–water mixture instead of water as working fluid have attracted much research interest over the past 20 years, since they have a potential to convert more energy in low–grade heat source into power and to improve the power generating processes in several ways. In this work comparative exergy analysis based on the second law of thermodynamics is carried out ...

  • Exergy analysis of geothermal electricity using the Kalina cycle

    The geothermal energy that is stored in the earth is so vast that could supply all the energy needed by humanity. The difficulty in tapping this energy lies in its diffusivity. The geothermal energy in regions near volcanoes is close to the surface and easy to use economically. In this paper a vapour dominated system will be examined. The electricity that is produced from such a system is ...

  • Extension of energy–utilisation diagram to power availability for exergy loss analysis

    Energy–Utilisation Diagram (EUD) has been used to identify exergy loss in general process units, whereas Power Availability Diagram (PAD) provides the difference between exergy changes of two pressure exchangers. Two modifications of the original PAD are proposed for better exergy loss visualisation. Firstly, the energy donor curve is shifted to the location of energy acceptor. Secondly, arrows ...

  • Utilisation of deep geothermal energy for heating purposes

    The Hot-Dry-Rock-(HDR) technology allows a location-independent utilisation of geothermal heat, because aquifers in deep formations, i.e. layers filled with water, are not necessary. The flow paths for the circulating water in a depth of 4 km are created by hydraulic fracturing of existing gaps. Due to the fact that this new technology is quite cost-intensive, high annual load duration of the ...
