Abstract
The object of this thesis is to study the various modes of desalination and analyze the energy and economic requirements. The desalination methods discussed are, single stage desalination, Long tube vertical Evaporator, Multistage Flash distillation, Solar Energy method, Freezing method, Reverse osmosis & Electrodialysis.
It was found that for vapor reheat process at 350°F input 639 ft-lbs/lb product required 2.01 kw-hr/100gal. product and the total cost 51.6c/1000gal.
Not one process is best for everyone. In countries close to the equator, the solar energy method is the best. Most other countries depend on flash distillation process, etc. So we can't draw a conclusion on a specific method, but in the immediate future, considering the price of electricity and energy going down, electrodialysis will be one of the most important desalination process to consider.
In the last few years, all work on the desalination has been curtailed by the government and research funded by the government has been stopped on this respect.
