“…[9][10][11][12][13][14][15] Later, various process researches on application of the oxygen blast furnace were also done. 16,17) The top gas recycling process with shaft gas injection based on the oxygen blast furnace has attracted special attention for reducing CO 2 emissions. The shaft gas injection in this process is similar to the reducing gas injection described above.…”

“…Arasto et al analyzed the technical assessment of the application of OBF with CCS to an ISP. The analysis showed that the CO 2 emissions from an ISP could be significantly reduced by the application of an oxygen blast furnace and CCS [29]. Based on the technical analysis, the economic profitability was further evaluated in Reference [30], which found that the investment on OBF or CCS depended on CO 2 , the fuels, and electricity prices.…”

High CO2 emissions and energy consumption have greatly restricted the development of China’s iron and steel industry. Two alternative ironmaking processes, top gas recycling-oxygen blast furnace (TGR-OBF) and COREX®, can reduce CO2 emissions and coking coal consumption in the steel industry when compared with a conventional blast furnace (BF). To obtain parameters on the material flow of these processes, two static process models for TGR-OBF and COREX were established. Combining the operating data from the Jingtang steel plant with established static process models, this research presents a detailed analysis of the material flows, metallurgical gas generation and consumption, electricity consumption and generation, comprehensive energy consumption, and CO2 emissions of three integrated steel plants (ISP) equipped with the BF, TGR-OBF, and COREX, respectively. The results indicated that the energy consumption of an ISP with the TGR-OBF was 16% and 16.5% lower than that of a conventional ISP and an ISP with the COREX. Compared with a conventional ISP, the coking coal consumption in an ISP with the TGR-OBF and an ISP with the COREX were reduced by 39.7% and 100% respectively. With the International Energy Agency factor, the ISP with the TGR-OBF had the lowest net CO2 emissions, which were 10.8% and 35.0% lower than that of a conventional ISP and an ISP with the COREX. With the China Grid factor, the conventional ISP had the lowest net CO2 emissions—2.8% and 24.1% lower than that of an ISP with the TGR-OBF and an ISP with the COREX, respectively.
