For years Barry Welch has been promoting the idea to designing wider cells. Some preliminary modelling work [1,2] already demonstrated some of the advantages of using wider cells like reducing external potshell area per electrolysis area ratio that help the design a low energy consumption cells and the potshell length to width ratio that help designing even higher amperage cells without further increasing the potroom width and hence the crane span.
A third advantage is to help reduce the formation of alumina concentration in the bath by allowing the addition of two new alumina feeding channels. The MHD cell stability code MHD-Valdis including its alumina dissolution module has been updated to support the addition of two extra longitudinal feeding channels in order to study the impact using three channels to feed alumina into the cell. Results obtained will be presented.
