Abstract :
Background and Purpose: The aim of this study is analyze the effectiveness of different measures for mitigation of greenhouse gas emissions in the steel industry and prioritizing strategies and management packages on greenhouse gas emissions in the countries’ steel industry. Steel industry after the power plants, is the second most energy intensive industry.
Analysis method: In this investigation at first steel industry development policies and their consequence on energy demand and greenhouse gas emissions in the baseline scenario. Then the policies due to the potential emission reduction were prioritized and the management package was suggested. Four scenarios was defined: Baseline Scenarios, optimization, renovation and replacement fuel in power generation scenarios in the steel industry
Findings: In case of running the three optimization scenarios, BOF scenario takes priority. If running modernization scenarios MIDREX takes priority. Since most of the country's electricity is generated by burning fossil fuels, in case of usage liquid fuels in power plants, replacing natural gas would show a significant decrease in carbon emissions, however considering that most of the country's power plants use natural gas fuel this scenario will be deleted
Conclusion: The results demonstrate that the greatest impact on reducing carbon dioxide equivalent emissions in 2030 is MIDREX scenario in the sub- renovation scenarios.
