Plant for producing potable water from sea water

摘要

In a plant for producing potable water from sea water, having a distillation unit (8) with an upstream unit (3) for precipitating calcium carbonate from the sea water by addition of soda, associated with a unit (5), coupled to a carbon dioxide generator, for producing soda from sodium hydroxide solution and carbon dioxide, coupled with an electrolysis device (7), connected to the distillation unit (8), for producing the sodium hydroxide solution from the brine of the distillation unit, the economics are to be improved by the provision of a steam power station with a steam turbine (16) and a generator (G) which is coupled to the steam turbine (16) and to which the electrolysis device (7) is connected; the distillation unit (8) is provided with a heater (10) which is connected as a condenser to the steam turbine (16). <IMAGE>
