Exploring cleaner routes of Alumina Production: Thermodynamic Simulation of Pedersen Process and CO2 Capture Integration via Calcium Looping

Abstract

Alumina industry stands out as a significant contributor to mineral scarcity because of the generation of bauxite residue during its production process. This study explores an alternative route to produce alumina: the Pedersen process. A thermodynamic simulation and an energy optimization are implemented to avoid bauxite residues and reach the goal of zero CO₂ emissions.
