DIRECT-REDUCED IRON PRODUCTION SYSTEM. |
摘要 |
This direct-reduced iron production system is provided with: a direct reduction furnace (13) that uses a high-temperature reduced gas (11) containing hydrogen and carbon monoxide to directly reduce iron ore (12a) to reduced iron (12b); an acid gas removal apparatus (16) comprising an acid gas component absorption tower (16a) that removes acid gas components (CO2 and H2S) in a reduction furnace exhaust gas (14) discharged from the direct reduction furnace (13) using an absorbing liquid (15) such as an amine-based solvent, and a regeneration tower (16b) that releases acid gas; and a degradation product removal device (17) that separates and removes degradation products in the absorbing liquid (15) that is recycled by the absorption tower (16a) and the regeneration tower (16b). |
