Loss of available energy in desalination plant
The available energy consumption in distillation plants is studied using the concept of exergy. The processes discussed in this paper are MSF, VTE and VC (vapor compression). The remarkable exergy losses in these processes are also dicussed in connection with various operation conditions. Generally, the exergy losses at the heat-exchange sections are dominant in comparison with other kind of losses. It is apparent from this study that the temperature difference between each side of a heating wall should be as small as possible from the viewpoint of available energy. But larger area of heating surface will be necessary to keep the small temperature difference. There fore, to consider these two points, the temperature difference and the heating area, in connection with the exergy loss must be useful for the plant design.
