Aluminium use cases André Augé, Aluminium Pechiney, MONSOON Turin, September 20th 2019 Aluminium use cases: Rio Tinto & AP Rio Tinto, a worldwide mining and metals company: • 4 product groups: Aluminium, Copper & Diamonds, Energy & Minerals, Iron Ore • We operate in more than 35 countries and employ 47,000 people. Europe North Asia America Africa South America Australasia Turin – September 20th, 2019 2 Aluminium use cases: Rio Tinto & AP Bauxite Alumina Aluminium 3 steps from the mine to the metal: • bauxite: 4 bauxite mines • alumina: 3 alumina plants • aluminium: 19 smelters in 6 countries • The Aluminium Dunkerque plant (North of France) is an aluminium smelter of 250 ktpy aluminium capacity [the highest-producing primary aluminium plant in the EU-28]. Turin – September 20th, 2019 3 Liberty Aluminium Dunkerque Continuous process High energy consumption High data intensive process Green house gazes emissions Turin – September 20th, 2019 Aluminium production process • MONSOON contribution: – Carbon area: • Predictive Maintenance • Anode quality prediction – Electrolysis area: • Bath and metal height prediction Electrolysis pot (with courtesy of AP) • Thermal balance prediction Si possible avec anodes 415 kg C/t Al Turin – September 20th, 2019 5 Focus on Anode Quality predictive function • predict non conformant production and trigger relevant actions to correct the problem (optimization) Anode non-quality can lead to non-homogeneous and reactive anodes Reduced lifecycle on pots (more frequent anode change) Incidents on pots CO2 over emissions due to the anode overconsumption Turin – September 20th, 2019 6 Anode Quality To provide a support to paste plant workers to improve anode density = quality With a predictive function which: • Detects on real time the periods (30 minutes) of improvable quality = classification • Identifies the main variables that caused the lower quality period • Gives recommendations to optimize the process to improve anode quality = optimization Turin – September 20th, 2019 The projects leading to this application have received funding from the European Union’s Horizon 2020 research and innovation program .
