Patent ID: 7842264

Claim:
A process for capturing and removing carbon dioxide gas, heavy metals, particulates, oxides of sulfur, oxides of nitrogen, or a mixture thereof, from a combustion gas mixture stream comprising: a) driving said combustion gas mixture stream through a first aerodynamic reactor with a first free jet formed from a first compressible fluid, said first free jet having incorporated therein first atomized liquid droplets or vapor; b) encapsulating said metals or said particulates into first liquid droplets and growing said first liquid droplets into first larger droplets by diffusion, condensation, impaction, interception, or a combination thereof; c) separating said first larger droplets from said combustion gas mixture stream in a first gas/liquid separator to form a first effluent gas mixture and a first effluent liquid stream; d) driving said first effluent gas mixture through a second aerodynamic reactor with a second free jet formed from a second compressible fluid, said second free jet having incorporated therein second atomized liquid droplets or vapor of an alkali metal alkaline solution; e) reacting said second atomized liquid droplets or vapor of said alkali metal alkaline solution, said oxides of sulfur, or said oxides of nitrogen, and at least a portion of said carbon dioxide to form first reaction products in the form of second droplets; f) growing said second droplets into second larger droplets by diffusion, condensation, impaction, interception, or a combination thereof; g) separating said second larger droplets from said first effluent gas mixture in a second gas/liquid separator to form a second effluent gas mixture and a second effluent liquid stream; h) treating said second effluent liquid stream through decarbonation, oxidation, evaporation, crystallization, or a combination thereof, whereby a portion of carbon dioxide gas and water vapor is liberated and alkali metal sulfate and nitrate is separated as a solid; i) discharging said second effluent gas mixture.
