Abstract

In this paper, mathematical modeling and optimization have been used to study the process integration feasibility of a steelmaking plant with methanol production to suppress carbon dioxide emissions. A blast furnace simulator with options to describe new technologies, such as cold oxygen injection combined with top gas recycling and natural gas injection is used as the core of the analysis. An optimization problem for the whole industrial complex is stated, where the specific steelmaking cost is minimized under process and resource constraints. The results show the potential of combining the technologies for different scenarios of costs of emission and carbon capturing and storage, and also illustrate how the steel production rate influences the performance of the system.
