Integrative optimization for energy efficiency, CO2 reduction, and economic gains in the iron and steel industry: A holistic approach
Exploring measures for low-energy consumption, low-CO2 emission, and high-economic benefit in the iron and steel industry is gaining increasing attention. This study innovatively establishes a holistic approach that integrates energy consumption, CO2 emission and economic benefit to optimize a typical steel mill. After optimization, the energy-benefit indicator has increased from 2.07 CNY/kgce to 2.83 CNY/kgce, with economic benefit improving by 97.58 CNY/t, energy consumption decreasing by 108.61 kgce/t, and CO2 emission reducing by 539.03 kg/t. Furthermore, this study scrutinizes the influence of energy structure, material structure, process parameter, and price on the energy-benefit indicator. Taking energy structure as an example, each additional 50 kg of pulverized coal injection will correspondingly improve the system's energy-benefit indicator by 0.02 CNY/kgce. These findings provide valuable insights into enhancing sustainability in the iron and steel industry, offering practical strategies for optimizing energy efficiency, reducing CO2 emissions, and achieving economic benefits.
期刊介绍：
The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns.
Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
