Observer-oriented Thermal Modeling for Hall-Héroult Process

Résumé

Temperature measurement is essential for the control of alumina dissolution and the stability of the cell in the Hall-Héroult process. However, the deployment of conventional sensors is a challenging task due to the corrosive nature of the process. In this paper, a zerodimensional thermal model for real-time bath temperature estimation is proposed. A thermal model candidate for cell temperatures is constructed using alumina concentration estimations and available measurements. The thermal model is validated on industrial data.
