| Abstract Scope |
The anode-to-stub connection is a significant contributor to the overall anodic voltage drop in prebake aluminum reduction cells, thereby representing an opportunity for substantial voltage savings through design optimization. In a previous publication a computational modeling design tool was presented and its features enumerated. The goal of this work is to validate that model using real-world field measurements taken from an operating aluminum smelter. To achieve that goal two anode assemblies were instrumented with thermocouples and voltage probes to collect time series data of the relevant temperatures and voltage drops at Alcoa’s Deschambault smelter in the Quebec province of Canada. This field data was then compared to outputs of several simulations to demonstrate the accuracy of the computational model. |
