Outotec® Pretium Calciner Optimizer

Combining real-time plant measurements with our profound process know-how, the Outotec® Pretium Calciner Optimizer ensures operational stability by continuously assessing process variables, automatically detecting and correcting detrimental process fluctuations, and calculating possible operational improvements. The system comprises several digital modules that support process operation in alumina calcination plants.

  • Reduces specific thermal and electrical energy consumption
  • Enhances operational stability
  • Detects and corrects detrimental process conditions, such as sudden changes in hydrate moisture
  • Makes fully automated load changes
  • Increases operator’s situational awareness
