WO/2007/139392 is referenced by 37 patents.

There is disclosed a method for processing an input gas stream, characterised by the following steps of: a) reacting the carbon dioxide of the input gas stream with an alkaline solution based on ammonia, for the formation of ammonium carbonates; b) reacting said ammonium carbonates from step a) with a saline solution for forming chemical products including alkaline metal carbonate and ammonium chloride; and c) processing said ammonium chloride from step b) by decomposition to form ammonia and metal chloride and/or hydrochloride acid; and d) step c) is implemented by using calcium oxide (CaO) to generate calsium chloride as said metal chloride, and/or by using magnesium oxide (MgO) to generate magnesium chloride as said metal chloride. Preferably the method is used in a combined process for removing carbon dioxide from combustion gas and desalination of water.

A modified solvay process, and uses thereof for processing co2-containing gas streams and for desalination
