Abstract

In this research, ammonia-water regenerative Rankine cycle driven by SOLAR ENERGY with LNG as its heat sink in condenser is simulated from the energy, EXERGY and EXERGOECONOMIC viewpoints. A relatively new method is used for cycle to perform in pinch point condition which causes improvement in the thermodynamic performance and output power of the system. Also, heat exchangers are simulated by using heat transfer correlations of shell and tube heat exchanger in detail. The results of base condition show the suitable performance of natural gas cycle from the thermodynamic and EXERGOECONOMIC points of view and illustrate the importance of using the natural gas cycle. Solar collector and condenser of ammonia-water cycle, because of their high cost values, are introduced as the components that should be further considered from the EXERGOECONOMIC viewpoint. The parametric analysis results show that in high inlet pressure of ammonia-water turbine the EXERGY efficiency and the total cost rate of the system have more suitable values while the net output power of the system decreases. Also, by changing the ammonia mass fraction, change of output parameters has a complicated pattern. Finally, by increasing the pinch temperature difference in heat exchangers the decreased amount of the system’s thermodynamic performance is more than the amount of the system’s economical performance improvement.
