SUMMARY:Flowsheet simulation of integrated green steelmaking (DRP-OBF-BOF/EAF) with the focus on CO2 emissions and OPEX 
DESCRIPTION:In view of the global climate emergency, the iron and steel industry bears a special responsibility. Around 30% of global industrial CO2 emissions are generated in the steelmaking value chain. Since there are several alternative ways to reduce CO2 emissions, which perform differently depending on factors like energy infrastructure and raw material availability and prices, an individual transition roadmap to less carbon-intensive steelmaking must be analyzed for each steel mill. The overall process simulation and subsequent analysis help to make the right decision between different green steel production route options.

This paper focuses on a steady-state flowsheet simulation in HSC, which was defined and performed using a case study to illustrate how the simulations can be effectively applied to design and optimize the steel value chain in a DRP-OBF-BOF-EAF configuration. This thermochemical process simulation enables process designers and plant operators to rapidly determine the impacts on CO2 footprint and OPEX due to variations in pellet quality, fuels, point of raw material addition and distribution of the products within the flowsheet. It is further demonstrated how scrap and waste circularity within the process can be optimized to balance OPEX and CO2 impacts.
