| Abstract Scope |
Carbon capture and sequestration (CCS) could potentially be used alongside an aluminum smelter. However, since this method requires CO2 concentrations of at least 4 vol% for economic and energetic feasibility, and the flue gas of modern smelters sits around 1 vol%, the feasibility of reduced flue gas suctioning, and its effect on the rest of the cell must be determined. A multiphysics Computational Fluid Dynamics (CFD) model was developed, which accounts for mass, momentum, and heat transfer, as well as thermoelectric and magnetohydrodynamic (MHD) aspects. An emphasis was placed on thermal and electrical effects of modified operations, as they more directly impact stability and efficiency of the cell, variations in current density, temperature, and changes in the side-ledge. For a potential retrofit, it is necessary to determine the feasibility of different operating parameters through accurate simulation. This paper discusses the development and results obtained during the modeling process. |
