Abstract: A system and a method is provided for removing carbon dioxide from a gas stream. One aspect of the method includes introducing a carbon dioxide-containing gas stream to an absorber. The gas stream is contacted with an ammonia-containing solvent for absorbing, with the ammonia-containing solvent, the carbon dioxide from the gas stream, thereby removing the carbon dioxide from the gas stream.

Abstract: A system for treating a flue gas from a combustion process comprises an absorber vessel configured to receive an aqueous ammonia solvent stream lean in CO2 and a flue gas stream having CO2, the aqueous ammonia solvent stream and the flue gas stream in contact in the absorber vessel in a counter-current arrangement to provide an outlet stream rich in CO2; a desorber configured to strip the CO2 from the outlet stream rich in CO2 from the absorber vessel at a temperature less than 100 degrees C. and to return the resultant aqueous ammonia solvent stream lean in CO2 to the absorber vessel; a source of heat configured to supply heat to the desorber; and a CO2 sequestration system for sequestering CO2 stripped by the desorber.
