Feed Strategy Optimization in Aluminum Smelters

Challenge

  • Difficult to maintain the bath temperature and excess ALF3 in the specified range
  • Shift engineer experience driving ALF3 addition directly impact the performance of the smelters productivity

Solution

  • Advanced Conditioning for identifying the deviations in the bath temperature and excess ALF3
  • Used historical data to model the required ALF3 feed to be added for optimal operations

Result

  • 6-10% decrease in unplanned downtime

 

  • Reduction in process variability by 35-40%
