Abstract
The present invention relates to a system and method using a reservoir specially designed for desalinating sea water. The invention makes it possible to evaporate the sea water and condense the resulting vapor at low pressure. Discharges into the sea resulting from said desalination operations have a low salt concentration. The present system and method can be used to recycle energy, even energy which is difficult to recycle, for desalinating sea water, or can be combined with other desalination techniques, for example such as MSF evaporation or MED distillation.
Claims9
A method of desalination of sea water, comprising:
- provision of a sealed reservoir disposed at the edge of the sea, comprising a filling device disposed on the roof, along with one or more openings disposed below sea level and being in communication with the sea;
- filling of the reservoir with sea water by the filling device, with the openings being hermetically sealed, followed by closing of the filling device to render the reservoir sealed;
- opening of the openings, placing the water which is inside the reservoir in communication with the water of the sea, wherewith the water level in the reservoir will decrease and will stabilize at a height h above the level of the sea, wherewith water vapor is produced in the reservoir above said height h, and wherewith the ceiling of the reservoir will have a height above the level of the sea greater than the height h to allow treatment of the water vapor produced in the reservoir;
- condensation of the water vapor produced, to obtain desalinated water;
- and
- removal of water from the water surface located at a height h in the reservoir toward the sea, in order to maintain the temperature of the water at the surface of the reservoir at the temperature of the water of the sea.
