Tiiermodynamic and Economic Analysis Of An Organic Rankine Cycle System Using Waste Heat From Mouau Power Plant
ABSTRACT
In this study, investigations are carried out in order to
find the best suitable working fluid for a given temperature limits of Organic
Rankine Cycles (ORCs) with the focus on thermodynamic analysis, economic
analysis, safety and environmental aspect. Making a suitable choice of working
fluid for the ORC is of vital importance for the cycle efficiency and net work
output. In this study, wet, dry and isentropic working fluids are investigated
from different perspectives. Engineering Equation Solver (EES) software package
was used as the main source to find thermo-physical properties of the working
fluids. Six organic working fluids used for this study are Butane, Isobutane,
Ri 1, Ri4lb, Ammonia and Ethanol. The cycle operating parameters are varied and
the effect of these parameters on the cycle performance and net work produced
are investigated. Based on the simulations, the cycle using Ammonia as working
fluid achieved the highest thermal efficiency (166.5%). The thermal
efficiencies obtained for the ORCs using butane, Isobutane, Ri 1, R141b and
Ethanol as working fluids are 57.98, 60.7, 88.09, 23.36, and 9.628 %
respectively. The six working fluids are investigated and the choice of the
working fluid is based on the safety and its environmental characteristics. The
Ammonia is found to be the most suitable organic working fluid compared with
the other five working fluids.
