Pulp to Paper Optimizer
Advanced Process Controls (APC)
Valmet Pulp to Paper Optimizer is an advanced process control (APC) that runs the board- and papermaking process automatically to the target production values with online predictions. It reduces end-quality variability as there is no need to wait for laboratory measurements before process adjustments. Valmet Pulp to Paper Optimizer leads to significant efficiencies as safety buffers of operator controller processes can be removed to the production of on-spec end-quality specifications.
Unique Optimization Potential
Valmet will generate final product quality models using multivariate analysis techniques. The quality models will be implemented as online predictions to support operational decisions via quality prediction dashboards (local and in Valmet Cloud).
The process predictions will be used as part of Valmet’s Pulp to Paper Optimizer, which utilizes Advanced Process Control (APC) technology to automatically optimize the process in terms of production, quality, and raw material costs. The solution also allows for the unique use of dedicated Valmet process analyzers, which offer excellence that is not available from any other similar system.
The primary target for process optimization is to facilitate savings through a more stable process operation. Advanced controls aim to reduce quality variability and stabilize the process, which would allow the process to be moved closer to economic optimum compared with baseline. The Valmet solution is designed to achieve mill quality objectives more accurately. The model will be updated regularly after implementation for long-term improvement.
Benefits
- Reduction of raw material consumption and thus costs
- Increased controllability i.e. stability of selected paper variable (e.g. SCT, CMT, Bulk, Burst, Porosity, Internal Bond, Tensile & Tear)
- Faster reaction time to process changes
- Fewer errors in process operation
- Increased consistency via reduced variance between shifts
- More stable process
