Energy Saving Potential of Screen Fractionation for Production of BCTMP, 20PEERS Conference

Over the last few decades, the continuing decline in mechanical pulp-based grades has led the pulp producers to modify operation and implement measures to reduce production cost in order to stay competitive. In spite of a considerable effort to reduce energy consumption, the latter is still a major portion of the production cost in the process of bleached chemi-thermomechanical pulping (BCTMP). In this study, we evaluated the impact of inter-stage screening fractionation (ISSF) and low consistency refining for producing BCTMP with the objective of reducing refining energy consumption while maintaining or improving bulk and strength properties.
