DUBAL has improved its anode performance in terms of Gross Carbon Consumption (GCC) and anode problems, while sustaining Net Carbon Consumption (NCC) in the potlines despite continuous amperage increase, raw material quality variations and multiple cell technologies. A 5% reduction in GCC was achieved over the past four years through optimisation of anode quality, modification of anode design and adjustment of pot operating parameters and practices. Optimisation was done based on the statistical analysis of key parameters, e.g., anode weight, butt parameters, bath height and line amperage. Anode parameters were monitored using a proprietary Rod and Anode Tracking System (RTS), which reconciles information pertaining to the anode with respect to butt location in the pot and its characteristics, raw materials, green and baked anode quality and the pot operating parameters. Statistical Reports were developed to facilitate faster and better decisions.
