Recent developments in process control for green anodes production

The construction of new smelters using the latest technology dives the opportunity to implement original control systems and to further improve the process for production of green anodes. The present paper highlights most of the PLC driven control loops that were developed and describes how much operation of the plant was smoothed on a continuous basis. Moreover, anode quality reached new records in steadiness while green rejects almost disappeared. The new generation of "gently controlled" paste plants went recently on stream, and key figures extracted from over 18 months industrial operation illustrate the benefits resulting from such improvements, even under very different project environments.
