Study of a desalination system for utilization of ocean thermal energy (In case of the coast of the Fiji Island in south Pacific Ocean)

This paper describes the performance analysis of desalination system in the Fiji island where is one of suitable sites proposed for the desalination. On December 12 similar to 18, 2003, December 4 similar to 6, 1999, December 3 similar to 5, 1998, December 3 similar to 4, 1997 and December 5 similar to 7, 1996 investigations of marine metrology, such as temperature, salinity, dissolved oxygen rate and submarine cross section was carried out by a research ship of the National Fisheries University. A conventional design for the desalination system is conducted with these data. The consuming electric power per product water is used as an objective function. A desalination rate of 1,000 tons per day using plate-type heat exchangers has been reported. Approximate correlation for a objective function is obtained.
