Simulator of Non homogenous Alumina and

This study addresses the significant issue of greenhouse gas emissions from primary aluminum production, particularly focusing on the harmful anode effect associated with insufficient alumina and its impact on current distribution in electrolysis cells. The objective was to develop a simulator that models the behavior of alumina distribution by dividing the electrolytic bath into non-homogenous concentration zones using discrete elements, which is a novel approach in this domain. The methodology involved creating a detailed electrical model to accurately assess current distribution across different anodic assemblies based on the alumina concentration zones simulated. The results indicate that the simulator can effectively predict the likelihood of low-voltage anode effects under various operational conditions, thereby contributing to the understanding of alumina distribution's role in optimizing cell energy consumption and stability. This new tool is crucial for the aluminum industry as it aims to reduce the occurrence of both high- and low-voltage anode effects, enhancing the environmental performance and efficiency of aluminum electrolysis processes.
