Recaust Optimizer

The Recaust Optimizer improves white liquor consistency, and causticizing efficiency through the use of more reliable instrumentation, advanced regulatory loop controllers and an expert system.

Pulp mill recausticizing systems are typically characterized by long response times and feedforward variables on the regulatory control loops. The Recaust Optimizer uses the BrainWave® predictive adaptive controller loop controllers, to reduce process variability combined with reliable low-maintenance process sensors and an expert system that calculates optimal set points and keeps the process operation within normal bounds.

System benefits include:

  • Consistent white liquor quality with variability reduced by 30% to 50% and lime mud content less than 30 mg/l
  • Higher pulp production through more consistent digester cooking
  • Reduced production cost through lower lime use and dead load combined with a decrease in make-up chemicals and energy consumption
  • Decreased plugging of pressure filters leading to lower maintenance requirements
  • Smoother plant operations with fewer process upsets
