Summary
In this paper an algorithm is described which, when implemented on a process control computer, can be used to infer from the electrical readings whether the alumina concentration in a cell is approaching the level at which an anode effect will occur. Unlike some techniques proposed elsewhere, the algorithm described here is simple and robust and requires very little data storage capacity. It is based on the Holt-Winters forecasting algorithm. An example is given of its application to routine electrical readings from an industrial cell in normal operation.
