Abstract

Language:

This work presents a system to detect short and open circuits suitable for Optibar ® inter-cell bars in copper electrorefining processes. The system is based in Optibar´s voltage connecting segments. Voltages are sampled and transmitted via WI-FI to a compatible SQL database every five minutes. The technique proposed performs sliding window analysis on anode-cathode voltages slopes to detect short and open circuits. The system was implemented in a refinery section of 20 cells with 1,100 cathodes. This approach demonstrates significant improvements in current balance and energy efficiency, as well as reduced occurrence of short circuits, indicating enhanced operational reliability in copper electrorefining.
