This research program will result in the ability to design high-performance pulp processing systems that canx000D
tailor fibre properties by removing debris, and by fractionating and selectively refining fibres to createx000D
high-value paper products. The program objectives include development of fundamental screening knowledge,x000D
understanding of how novel features of the screen cylinder and rotor increase debris removal, and thex000D
development of a fractionation and refining model that predicts the effects of varying old corrugated cardboardx000D
treatments on linerboard properties. This research supports the Canadian pulp and paper industry and builds onx000D
the existing partnership between UBC and Aikawa Fiber Technologies (AFT), producer of pulp screeningx000D
components. It extends the group's previous research work and expertise in the areas of fluid dynamics ofx000D
screening, low consistency (LC) refining, pressure screen fractionation, and fractionation-LC refining systems.x000D
The proposed research program consists of one PhD project and one Master's project with two parts. The PhDx000D
project will focus on modeling and simulation of screening and LC refining specialty products. The master'sx000D
project, with two consecutive students, will focus on screen cylinder design and optimization through thex000D
simulation of fibre and debris trajectory, as well as modelling of screen efficiency and capacity.x000D
Innovative high performance pulp processing system design will be trialed at pilot and mill scale and laterx000D
implemented in the Canadian industry, which will enable Canadian pulp and paper companies to improve thex000D
quality and value of the products they produce. This new understanding will lead to advanced cylinder designsx000D
that will ensure the long term competitive advantage of AFT, an advanced global manufacturing company withx000D
major a manufacturing facility in Sherbrooke, Quebec.
