Environmental and techno-economic analyses of oxygen blast furnace systems integrated with carbon capture and utilization strategy
For mitigating net CO2 emissions of the oxygen blast furnace (OBF) system, the top gas recycling by connecting a Monoethanolamine (MEA)-based CO2 capture process as Scenario 1 (OBF + CC) and a carbon capture and utilization (CCU) process as Scenario 2 (OBF + CCU) is proposed. Scenario 2 utilizes a T...

| description | For mitigating net CO2 emissions of the oxygen blast furnace (OBF) system, the top gas recycling by connecting a Monoethanolamine (MEA)-based CO2 capture process as Scenario 1 (OBF + CC) and a carbon capture and utilization (CCU) process as Scenario 2 (OBF + CCU) is proposed. Scenario 2 utilizes a Triethylene glycol (TEG) physical absorption process for producing an industrial-grade 99.999 % purity liquid CO2 product. Carbon tracking in Aspen Plus indicates that Scenario 2 achieves significantly lower CO2 emissions with 4.1 kg CO2/tHM than Scenario 1 with 770 kg CO2/tHM. To synergize Aspen Plus® modeling and environmental impact assessment using SimaPro®, Scenario 2 has a lower impact on eutrophication potential, acidification potential, water depletion, and fossil resource depletion as compared to Scenario 1. Techno-economic analysis of Scenario 2 indicates that the liquid CO2 product generates a potential profit of 973.95 USD/tHM, which fully offsets the CO2 production cost of 378.33 USD/tHM in the CCU process. |
