Zusammenfassung:	To provide a method and an apparatus for carbon dioxide fixation, which enable carbon dioxide to be fixed in a stable state without being stored in an underground aquifer, and exhaust gas desulfurization equipment.SOLUTION: An apparatus for carbon dioxide fixation comprises an absorption tower 10 that desulfurizes exhaust gas, including sulfur oxides, by sea water, and a reaction tank 60 that produces such a stable compound as a mineral by adding an alkali earth metal or an alkali metal to the sea water absorbing the sulfur oxides from the exhaust gas by the absorption tower 10.SELECTED DRAWING: Figure 1 【課題】二酸化炭素を地下の帯水層に貯留することなく安定状態で固定し得る二酸化炭素固定方法及び装置と排煙脱硫設備を提供する。【解決手段】硫黄酸化物が含まれる排煙を海水で脱硫する吸収塔１０と、吸収塔１０で排煙から硫黄酸化物を吸収した海水にアルカリ土類金属又はアルカリ金属を添加して鉱物のような安定した化合物を生成する反応槽６０とを備える。【選択図】図１
