10000000 gallon per day secondary refrigerant freeze desalting plant
This report describes a continuous process for producing potable water from sea water by partial freezing. Ice slurry is produced in a freezer by direct contact of sea water with liquid butane at the pressure slightly below atmospheric at which butane boils at the temperature of freezing saline water, deriving its heat for vaporization from ice formation. The resulting slurry of ice in brine is sent to a washer, where the ice is washed substantially free of salt, using part of the melted by direct contact with slightly compressed butane vapor from the freezer. Butane condenses as it melts the ice, and condensate is recycled to the freezer. Cold from the potable water and product brine streams is recovered in the incoming feed by a heat interchange system employing vaporization and condensation of butane in direct contact with the aqueous streams. Since the system operates below ambient temperature and since heats of compression and pumping and heat in the feed sea water must be removed, heat is pumped from the system by compressing butane vapor not condensed in the melter to a pressure at which it can be condensed by the exiting product steams.
