Abstract:
1. A method for capturing CO 2 from a flue gas resulting from a combustion process, and exhausting a stream of CO 2 containing any combination of chemicals including H 2 O, Ar, N 2j O 2 , SO χ , NO χ , and Hg and traces of other post-combustion materials the method comprising the steps of: combusting a fossil fuel and pure oxygen inside a boiler producing a flue gas; conveying at least a portion of the flue gas into at least one heat exchanger defining a first heat exchanger; cooling the flue gas in said at least one first heat exchanger with a cooling fluid to a temperature at which condensable vapors are condensed to enable the liquid condensate to be removed as liquid condensate from the heat exchanger; filtering the liquid condensate and cooling fluid-defining a filtered liquid condensate so that pollutants are disposed of and pure water is released; compressing the gas exiting the first heat exchanger in at least one compressor until it is a CO
