摘要：
Included are: a direct reduction furnace for reducing iron ore directly into reduced iron using a high-temperature reducing gas including hydrogen and carbon monoxide, an acid gas removal unit having an acid gas component absorber for removing, with an absorbent such as an amine-based solvent, acid gas components (CO2, H2S) in a reduction furnace flue gas discharged from the direct reduction furnace, and a regenerator for releasing the acid gas, and a degradation product removal unit for separating and removing a degradation product in the absorbent used by circulating through the absorber and the regenerator.
