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

该研究项目将能够设计高性能纸浆加工系统，通过去除碎片、分馏和选择性精炼纤维来调整纤维特性，以创造高价值的纸制品。该计划的目标包括开发基本筛选知识、了解筛筒和转子的新颖特征如何提高碎屑去除率，以及开发分馏和精炼模型来预测不同旧瓦楞纸板处理对挂面纸板性能的影响。这项研究支持加拿大纸浆和造纸工业，并建立在 UBC 和纸浆筛选组件生产商 Aikawa Fiber Technologies (AFT) 之间现有合作伙伴关系的基础上。它扩展了该小组之前在筛选流体动力学、低浓（LC）精炼、压力筛分馏和分馏-LC精炼系统领域的研究工作和专业知识。拟议的研究计划包括一个博士项目和一个硕士项目，以及两个硕士项目。部分。该博士项目将重点关注筛选和液相色谱精炼特种产品的建模和模拟。该硕士项目连续有两名学生，将重点通过纤维和碎片轨迹的模拟以及筛网效率和容量的建模来设计和优化筛筒。创新的高性能纸浆加工系统设计将在中试和工厂进行试验规模化并随后在加拿大行业实施，这将使加拿大纸浆和造纸公司能够提高其生产的产品的质量和价值。这种新的认识将带来先进的气缸设计，从而确保 AFT 的长期竞争优势，AFT 是一家先进的全球制造公司，主要制造工厂位于魁北克省舍布鲁克。
