Carbon Emission Digital Simulation and Process Transformation of Main Process in Steel Production
According to China's proposed"double carbon"strategy,the iron and steel industry to reduce carbon emissions in a tight schedule,the task is heavy,there is no time to lose.As an important means of reducing carbon emissions,digital simulation on carbon emissions from steel production is currently mainly focused on a single process such as ironmaking and steelmaking,and there are problems such as the lack of multi-process carbon emission model and the lack of systematic process optimization schemes.Therefore,digital simulation and process transformation of carbon emission in the whole process of steel production were carried out.Firstly,this paper constructed the"5+1"full-process carbon emission mathematical model and developed the InteCast Steel Production Carbon Emissions Simulation Software to solve the lack of main process flow models;Secondly,based on the data of Baosteel and Tangsteel,the match was over 96％,which confirmed the accuracy and reliability of the model and software,and laid the foundation for process transformation;Finally,it covered the four aspects of technological innovation,carbon recovery,carbon neutralization and energy change.The NTC(New Technology Combination)plan,post-combustion CO2 recovery plan,pre-combustion CO2 recovery plan and hydrogen metallurgical short-process production plan were systematically proposed.The four schemes,from easy to difficult,can serve the"double carbon"plan in the near term,middle term,middle and late period,and have a good reference for the steel industry to reduce carbon emission.
