Abstract:
A process for desalination of Sea or brackish water, comprising mixing ammonia (NH.sub.3) into said water to form an effective amount of ammonium hydroxide (NH.sub.4 OH) to react with NaCl salt molecules present in said water and weaken the NaCl bonds in said molecules; spraying said water as a fine spray near the top of an enclosed process chamber; exposing the sprayed water to an effective amount of CO.sub.2 combustion exhaust gas to react with said salt molecules and form sodium carbonate (Na.sub.2 CO.sub.3) and ammonium chloride (NH.sub.4 Cl) solids; settling said solids in a clarifier below said process chamber; removing said solids through an underflow outlet in said clarifier; discharging exhaust gas from said process chamber; and removing desalinated water as an overflow from said clarifier.
