| Abstract Scope |
With the shortage of green energy supply, the growing demand for aluminium and needs to lower the Carbon footprint smelters are shifting to high productivity, minimum energy cell operation as well as targeting minimum net carbon. The anode shape, size, and setting pattern in the cells all have an impact on both the energy efficiency and the net carbon. Slots have been introduced to lower the resistance of the electrolyte. While slots therefore enabled increasing cell line current, there has been a consequential reduction the anode cathode distance and the electrolyte volume. Slots have reduced the driving force for electrolyte flow and mixing. Increasing anode mass has resulted in extended times for the anode to preheat and draw full current. Thus the changes have introduced greater spatial variation in cell conditions. This paper open discussion in the hope of determining the perfect anode design for smelters beyond the year 2020. |
