In late 2004 the Tembec Pine Falls mill, teamed up with Metso’s Paper and Automation divisions to achieve optimal refining performance by consistently producing high quality pulp with minimal power costs. These objectives required the implementation of advanced controls and real time optimization technologies combined with refiner segment configuration changes on the mainline refiners to prove the concept and measure the savings contribution of the segments and controls independently. As significant energy savings and a large reduction in pulp quality variability were accomplished and sustained, the mill decided to proceed with a permanent installation of the main line system and extended the controls and optimization to incorporate screening and reject refining. A mill peak power control and optimization module was also implemented to optimize operations by managing total mill power and peak load.
