The Future of Refining
– Automation for Final Product Quality

Author: Pat Dixon, VP of Automation, Pulmac Systems

Event: TAPPICON 2022

This presentation will show current technology that can be applied in new ways to improve product quality on a paper machine.

Practical limitations and challenges will be addressed to ensure realistic expectations.

The Fundamentals of Refining

  • Used on virgin fiber to enhance bonding
  • Used on recycled fiber in a more limited capacity
  • Used in TMP to defiber chips
  • Controlled specific energy targets to account for consistency and production rate changes
  • Higher specific energy generally yields lower freeness
  • Not to be used like a fast-acting actuator (valve)
  • It can be used to help meet the strength targets of the final product
