Advanced Process Control for pulp and paper mills

ANDRITZ AUTOMATION offers a suite of advanced control solutions that are revolutionizing control at pulp and paper mills across North America, South America and Europe. We have helped producers large and small remove bottlenecks, reduce energy and chemical consumption, produce higher quality products more consistently and lower production costs—all of which results in hundreds of thousands of dollars saved.

Control Stabilization
Our patented PID-replacement controller, BrainWave®, easily integrates into your control system via OPC and has an average implementation time of less than two weeks, saving tens and even hundreds of thousands of dollars compared to traditional methods. And, best of all, BrainWave can be deployed and maintained by existing plant personnel.

BrainWave outperforms traditional Proportional-Integral-Derivative (PID) systems because of its two main components: an adaptive model and a predictive controller. The adaptive model builds its own live models during normal plant operations, a powerful feature not offered by traditional Model Predictive Control (MPC) systems.

BrainWave’s predictive controller accurately forecasts process responses and accounts for multiple objectives. It adapts to process conditions such as changes in production rate or operating point, keeping your process on target. BrainWave can also accept measured disturbance inputs like raw material properties and adjust before your process is pushed off target (PID, by comparison, must wait for the error to occur, then react).

We offer a full range of control solutions for pulp and paper processes, including:
• BrainWave Digester
• BrainWave O2 Delignification
• BrainWave Bleaching
• BrainWave Pulp Dryer
• BrainWave Recaust
• BrainWave Lime Kiln
• BrainWave Evaporator

Control Optimization
Many plants that have achieved outstanding success stabilizing processes with BrainWave, have taken their operations to the next level with ACE® (Advanced Control Expert). ACE is an automated “expert operator” that works in conjunction with the BrainWave solution to fully optimize a process.

Once BrainWave has stabilized a process, ACE can be implemented to manage the operation, ensuring that you are producing the highest quality output at the lowest price. The expert operator in ACE is always at full attention, never distracted, and achieves optimum conditions for your plant.

It advises the operator in his native language about what strategy is operating and what constraints it is up against. It determines the best set points, enabling a process to run at maximum efficiency while at the same time reducing operating costs.
