illustrates the schematic of the combined GT-MSF system for
simultaneous generation of the electric power and fresh water. Power
generation cycle includes compressor, combustion chamber and gas
turbine that have a nominal output power of 65 MW. Also, a heat
recovery steam boiler was used to produce saturated steam of
distillation unit. All parts of systems were modeled and simulated and
energy and exergy equations were developed and applied to evaluate
performance of combined system

proposed GT power plant are listed in

The brine circulating multi stage
fl
ash desalination (MSF-BR) has
been schematically illustrated in
Fig. 2
. As shown in this
fi
gure, the
process involves heating seawater to a high temperature then passing
it through a series of stages where the pressure and temperature are
reduced progressively. This process causes the sea water to
fl
ash at
each successive stage. The vapor thus released is condensed and
collected as distilled water. In the MSF process, the brine recycle is
