SUMMARY:Supporting green steel transformation using digital twins to design alternative production routes
DESCRIPTION:Steel industry is responsible for about 8% of worldwide CO2 emissions and faces significant challenges to meet defined climate targets for the upcoming years. Recently the evaluation of transition solutions for state-of-the-art steel making process routes and finally carbon neutral steel production are the focus of investigations of steel producers. Massive changes in production routes are required to achieve a carbon net-tero steel production. The metallurgical model library “m.simtop” developed by Primetals enables the implementation of digital twins for any  production scenario and enhances all kind of evaluations. The digital twins are fully based on chemical and metallurgical first principle modelling and capable of precisely depicting all kinds of integrated and alternative steel production routes. Utilizing this powerful platform, Primetals implemented a study on numerous process routes covering different technologies. In this work a selection of a comparison of state-of-the-art direct reduction steel making routes including variations thereof and also for emerging technologies is provided. Production routes covered are Midrex natural gas and hydrogen based as well as new processes such as Hyfor and HyREX. A comparison of consumption figures, OPEX as well as CO2 emissions will be discussed.
