Anode effects (AE) are considered a nuisance for aluminium production due to the numerous negative impacts that they generate in an electrolysis cell. Hence, great efforts have been deployed to minimize the occurrence of this event. Using online anode current monitoring, Alouette introduced an algorithm to detect abnormalities prior to an AE, allowing sufficient time to apply a corrective action before its occurrence. Several sets of strategies were tested to evaluate the best approach to correct the situation without generating additional problems in the cells. Finally, a communication was established between the individual anode current monitoring system and the cell control system of two pots to automatically launch preventive treatments of AE. A decrease in the total number of anode effects along with the cell instability is noticeable. Other indicators were also compared to make sure that no deterioration in the cells condition occurred over time.
