Sustainable desalination using ocean thermocline energy

摘要: Abstract The conventional desalination processes are not only energy intensive but also environment un-friendly. They operating far from thermodynamic limit, 10–12%, making them un-sustainable for future water supplies. An innovative required to meet sustainable goal and COP21 goal. In this paper, we proposed a multi-effect system operated with ocean thermocline energy, thermal harnessed seawater temperature gradient. It can exploit low differential between surface hot deep-sea cold-water produce fresh water. Detailed theoretical model was developed simulation conducted in FORTRAN using international mathematical statistical library (IMSL). We presented four different cases cold varies 5 13 °C MED stages 3 6. shows that the cycle achieve highest level of universal performance ratio, UPR = 158, achieving about 18.8% ideal limit. With major input emanated renewable solar, is truly “green desalination” method global warming potential (GWP), best suited tropical coastal shores having bathymetry depths up 300 m or more.
