Indicators for Forecasting Pitch Season, 2002 Technology Summit Proceedings

Matthew A. Blazey, S. Allen Grimsley, Gordon C. Chen 

"Pitch season" is always a stressful and challenging time for papermakers. With current industry trends such as increasing mechanical pulp content, mill closure, and just-in-time chip delivery, the potential for severe pitch outbreaks has increased significantly. In order to prepare defensive strategies, papermakers want to know if there are indicators that can forecast a "pitch storm" before it hits. Analysis of TMP pulp samples, inside and outside of pitch season, suggests that deposit outbreaks are more closely related to the composition of wood pitch rather than the absolute amount of pitch present in the system. This paper examines factors contributing to pitch season and analytical methods that can be used to monitor them.
