Calcium looping carbon capture was simulated for a steel plant and three fuel cases were studied: coal, coke, and half coal/coke. The steelmaking production was about 1.2 t of liquid steel per hour at >99.85% purity by weight. This study evaluated the effect of carbon capture efficiency and raw material cost on the lime flow rate in the calcium looping section. Increasing the lime feeding flow rate achieved higher efficiency but at a higher cost. The overall captured efficiency was higher than the flue gas captured efficiency at a low lime feeding flow rate but lower at a high lime feeding flow rate. Then, the overall captured efficiency tended to decrease at high lime feeding flow rate because raw materials were used too much for carbon capture and caused overall carbon dioxide emission more than the content of captured carbon dioxide in the product stream. Coal as fuel plays an important role in carbon emission reduction as one of the raw materials, along with the utility cost and the raw material cost in calcium looping section.

“…Moreover, more researchers paid attention to the exergy analysis of single equipment, especially equipment in ironmaking system. For example, Qin et al [ 46 ] calculated the energy efficiency and exergy efficiency of coking process and pointed out that it could improve the energy efficiency and economic efficiency by recovering waste heat. By optimizing the sinter cooling process, Feng et al [ 47 ] found that the recovery exergy can be improved by adopting a lower sinter layer porosity and a larger velocity of inlet air (Tian, Ni, Jiang, & Wu, 2019).…”

Application of energy saving and consumption reduction technologies in the iron and steel industry (ISI) is an effective way to achieve sustainable development. As the highly energy‐consuming ironmaking system is an important part of steel production, reducing its exergy loss is of great significance for overall energy saving in ISI. The optimization model of the ironmaking system is established in this study based on the law of conservation of mass and the second law of thermodynamics. For the target of minimum exergy loss, material and energy systems of ironmaking are optimized and analyzed. Factors that influence the ironmaking system are further discussed. The results show that the minimum exergy loss of the ironmaking system is 4605.80 MJ t‐HM−1 by improving operation conditions. Among them, 51.15% of the total exergy loss is contributed by the blast furnace ironmaking process.
