CARBON DIOXIDE RECOVERY FACILITY AND RECOVERY METHOD, CARBON DIOXIDE STORAGE METHOD, CEMENT CLINKER PRODUCTION SYSTEM AND CEMENT CLINKER PRODUCTION METHOD, AND DRY ICE PRODUCTION METHOD
To provide a carbon dioxide recovery facility capable of efficiently recovering carbon dioxide from a carbon dioxide emission source.SOLUTION: Provided is a carbon dioxide recovery facility 100, including: a first preheater 50 for bringing an exhaust gas containing CO2 into contact with a first material containing CaCO3 to cool the exhaust gas and preheating the first material; a heater 20 into which the first material preheated by the first preheater 50 is introduced, and in which a carbon-containing fuel is burned using a high-oxygen concentration gas having a higher oxygen concentration than air to pyrolyze CaCO3, thereby generating a first gas containing CO2 and a solid containing CaO; a reactor 40 into which at least a part of the solid containing CaO generated in the heater 20 and the exhaust gas cooled in the first preheater 50 are introduced to produce a solid containing CaCO3 and produce an exhaust gas and a second gas having a lower CO2 concentration than that of a first gas; and a conveyance path D1 for introducing the solid containing CaCO3 produced in the reactor 40 into the heater 20.SELECTED DRAWING: Figure 1
【課題】二酸化炭素排出源から二酸化炭素を効率よく回収することが可能な二酸化炭素の回収設備を提供すること。【解決手段】ＣＯ２を含む排ガスとＣａＣＯ３を含む第１原料とを接触させて、排ガスを冷却するとともに第１原料を予熱する第１予熱装置５０と、第１予熱装置５０で予熱された第１原料が導入され、空気よりも高い酸素濃度を有する高酸素濃度ガスを用いて炭素含有燃料を燃焼してＣａＣＯ３を熱分解し、ＣＯ２を含む第１ガスとＣａＯを含む固形分とを生成する加熱装置２０と、加熱装置２０で生成したＣａＯを含む固形分の少なくとも一部と、第１予熱装置５０で冷却された排ガスとが導入され、ＣａＣＯ３を含む固形分を生成するとともに排ガス及び第１ガスよりもＣＯ２濃度が低い第２ガスを生成する反応装置４０と、反応装置４０で生成したＣａＣＯ３を含む固形分を加熱装置２０に導入する搬送路Ｄ１と、を備える二酸化炭素の回収設備１００を提供する。【選択図】図１
