ABB releases digital solution for control of wet end process

ABB has launched Wet End Control, the latest product in its Advanced Process Control (APC) system, to provide complete digital control over wet end operations.

Wet End Control stabilizes the wet end process and reduces variability by controlling, monitoring and optimizing retention performance. It uses a multivariable model predictive control approach to predict future wet end process behaviour, making automatic adjustments to stabilize ash levels, reduce white water consistency variability and minimize chemical and filler dosages.

The company says this results in improved machine runnability by helping to reduce sheet breaks, and accelerate grade changes and break recovery.

Papermakers can then track performance from the wet end to the final sheet.

Wet End Control is available as a subscription-based service delivered via ABB Ability Collaborative Operations, with structured remote monitoring and expert analysis of control performance for sustainable results.
