Predicting and Avoiding Wet-End Paper Breaks and Other Process Event

Presented by: PPCL – Experts in Geometric Process Control (GPC) and CPM Modeling
Join us for an in-depth webinar demonstrating how PPCL’s CPM multivariable modeling technology is being successfully applied in Pulp Mills and Stock Preparation processes to reduce costly paper breaks and improve production stability.
Paper breaks—especially at the Wet End of the paper machine—are a major cause of downtime and lost production. Just one break per day, with an hour of cleanup and restart, can result in up to 4% production loss. These events often stem from unmeasured process variations—such as pulp composition changes from recycled materials—that current control systems can’t predict or respond to.
In this session, you will learn:
• How multivariable geometric modeling (a unique form of machine learning without equations) can detect subtle process changes that often lead to breaks.
• Why ‘broke’ paper reprocessing introduces additional variability and instability in stock preparation.
• How Operating Envelope models provide real-time guidance to Wet-End operators, helping to adjust machine settings in response to unexpected pulp properties.
• How CPM models are applied in batch, multi-grade, and multi-mode processes, with automatic real-time switching between modes or grades.
• Why PPCL’s GPC and CPM solutions require only standard Windows PCs—no specialized hardware or complex infrastructure.
We’ll also draw comparisons with other applications of this technology in industries like gas processing, where sudden feed changes can have similar impacts—demonstrating the broad applicability of this predictive, real-time modeling approach.
