This project explores the potential of hydrogen and ammonia as alternative reducing agents for the deoxidation, or “poling,” of blister copper. Traditionally, this process relies on hydrocarbons, which produce substantial CO2 emissions and face operational inefficiencies such as low thermal performance and tuyere blockages. With the use of computational fluid dynamics (CFD) modeling, the research aims to evaluate the technical feasibility of sonic jetting regimes for hydrogen and ammonia injection. This innovative approach seeks to optimize the injection process while minimizing the carbon footprint, aligning with global decarbonization goals. The image is of our most recent simulations.
