The invention relates to desalination of Seawater and of brackish water and removal of harmful CO2 gas in exhaust from combustion apparatuses. The exhaust, rich in carbon dioxide (CO2) is diverted to a process chamber, where Seawater, after being mixed with ammonia, as a catalyst to weaken the salt molecules, is pumped into the chamber and dispersed at many points near the top as a fine spray, exposing the salt to the CO2 gas there. The internal bonds of the salt molecules (NACl) are weaker by the ammonia in the water attaching and pulling on their Cl atom. The CO2 in the chamber is attaching and pulling on the Na atom of the salt molecules and further reduces the bond, breaking them apart. Two heavy solids are formed and are removed in a clarifier below. Desalinated seawater in large quantities per ton of salt, over flows from the clarifier, for use in communities and for agriculture. Therewith is also harmful CO2 in the exhaust removed, before being discharged from the process chamber to the environment. The solid NH4Cl can be recycled for ammonia and the second solid NH2CO3 is a saleable product, which may more than pay for the process. |
