The invention relates to a method for removing carbon dioxide from flue g ases of incinerators as well as an apparatus for carrying out said method. I n a first step of said method, the flue gases are freed from dust (3) and ni tric oxides (2), and in a subsequent step, the pre-purified flue gas is brou ght in contact (5) with an aqueous ammonia solution in the presence of an ox idant such that the carbon dioxide of the flue gas reacts with the ammonia t o produce ammonium carbonate. In a subsequent step, the ammonium carbonate p resent in the aqueous solution is thermally decomposed (6), and the gas flow s generated during the decomposition process are fed to a urea generator (7) . |
