Objectif
Pulp suspensions are different from other solid-liquid systems because of the unique interactions between the different components of the fiber furnish: fibers, fines, fillers, additives, DCM, etc. Fiber-fiber interactions, fiber-water, fiber-fines, fiber-additives, fines-additives, etc., are very important in these heterogeneous samples giving rise to complex shear mechanism that are different from classical slurry systems. The flow properties of the pulp suspensions are important for the optimal functionality of most unit operations in pulp and paper- making.
The aim of this project is to develop a novel device to study pulp suspensions behavior and to explore two potential uses for the new device: the improvement on equipment design and wet end chemistry optimization. The identified benefits are: pumping energy cost saving of 19%; maintenance cost reduction by 2%; performance improvement in pulp processing, which also improves product quality; and potential cost reduction by means of wet end optimization.
