Reduce Energy Consumption through Plate Design in Thermo-Mechanical Pulp (TMP)

摘要

Empirical models were developed to quantify the effects of seven refiner plate design variables and three process variables on the pulp quality variables. These experiments were carried out in a full scale TMP plant. A combination of the Design of Experiment (DoE) and the Multiple Variable Optimization (MVO) techniques provided a numerical method to reduce energy consumption by 8-15% while maintaining the quality of pulp. This paper describes the methodology used to develop these models and then presents the mill results from application of these models.
