| Abstract: | In this paper, a preliminary economic analysis among some seawater desalination technologies such as reverse osmosis, multi - stage flash and freezing is presented. Desalination by freezing is of great prospect due to its low energy consumption, low cost, slight corrosion and scaling. This paper emphatically reviews the principles and production processes of natural freezing and artificial freezing including Direct Refrigerant Freezing Process, Vacuum Freeze - Vapor Process, Vacuum Freezing High Pressure Ice-Melting Process, Vacuum Freezing Multiple Phase Transformation Process and Exchange Crystallization Freeze Desalination Process. In addition, some methods of sea ice desalination are also described in this paper. |
