In 2024, Aurubis Hamburg site installed two new hydrogenHydrogen-ready anode furnacesAnode furnace as part of its planned shutdown. After more than 50 years of operationOperation, the old furnacesFurnace were nearing their end of lifeEnd of life. Faced with this opportunity, Aurubis decided to install new anode furnacesAnode furnace during this time window. While the new furnacesFurnace incorporated many new features designed to increase safetySafety and improve operational flexibility, the main designDesign was influenced by the company’s decision to have them hydrogenHydrogen ready for “poling”. Being able to decarbonize this core process of the copper productionCopper production was in line with Aurubis’ environmental targets and would allow the site to save up to 5000 t of CO2 per year. This paper will discuss the journey of these new anode furnacesAnode furnace from setup of the designDesign criteria to commissioning. The full-scale hydrogenHydrogen experiments conducted in 2021 which played a major role in the new designDesign will be presented as well as the numerous challenges faced with installing larger furnacesFurnace into a brownfield site with limited footprint. The importance of an experienced project team combined with dedicated partners to overcome challenges from engineeringEngineering to installation will be discussed.
