Control Performance Assessment for Pulp & Paper

by ANDRITZ AG

Optimize control loops for pulp and paper processes with actionable insights and recommendations.

Discovers unknown and hidden processes, prioritizes saving opportunities, and supports users in achieving more practical and cost-effective decision-making. Metris CPA continuously monitors the regulatory process and intelligently recommends optimization actions based on years of embedded expertise. Driving loops to optimal achievable performance by few steps. PID Tuner provides fast and cost-effective solutions for optimizing mill control loops.

Why invest in loop optimization?

  • 30% of loops are usually in manual
  • 30% of problems in sensors, actuators
  • About 25% of Control Loops are initially configured by using default PID Parameters and remain the same for years
  • About 20% of Controllers operate under saturated conditions
  • Opportunities in tuning and final control elements are hidden in at least 30% of Control Loops (15% no sense)
  • 20% wrong and/or improper design
  • Only 20% of loops operate better in automatic mode than in manual mode!


Other important points to consider:

  • Usually, the loops are not optimized in the start-up process
  • During its life, the valves are worn out (actuators) and increase variability of PV (process variable)
  • Tuning should track changes in the process
  • Tuning should track changes in raw materials
  • In general, a loop is only reviewed when one of its pieces of equipment fails: the controller, sensor, or actuator.
  • In reality, the performance of a controller loop may decline over time due to wear of actuators, alterations in process, changes of recipe/set-points, alterations of reagents (concentration, etc.).

Due to the above, loops can present high variability, causing impact on the process and assets.
