Simulation of CO2 Emission Reduction Potential of the Iron and Steel Industry using a System Dynamics Model

摘要

It is important to focus on greenhouse gas emissions from the steel industry because the iron and steel sector emits about 3.2% of the total greenhouse gases in the world. The present investigation examines the mitigation potential of future carbon dioxide reduction technology options in the iron and steel industry using a system dynamics approach. A system dynamics model is constructed based on energy, materials, and process flow: to analyze the carbon dioxide emission reduction technologies and energy use in iron and steel manufacturing processes. We analyzed steel manufacturers' carbon dioxide emissions and the quantity of energy and materials consumed from coking and sintering, iron-making, continuous casting and rolling processes, and stainless processes. Six different carbon dioxide reduction technologies were introduced into the system in our model.
