Advanced pulp processing system design

这项研究计划将产生设计高性能纸浆处理系统的能力，该系统可以通过去除碎屑以及通过对纤维进行分级和选择性精炼来定制纤维特性，从而创造出高价值的纸制品。该计划的目标包括开发基本的筛分知识，了解筛筒和转子的新特性如何提高碎屑清除量，以及开发一种分级和精炼模型，该模型预测不同的旧瓦楞纸板处理对纸板性能的影响。这项研究支持加拿大纸浆和造纸行业，并建立在UBC和爱川纤维技术公司(AFT)之间现有的合作伙伴关系基础上，爱川纤维技术公司是纸浆筛分部件的生产商。它扩展了集团之前在流体动力学领域的研究工作和专业知识，包括筛分、低浓(LC)精炼、加压筛分和分馏-LC精炼系统。博士项目将专注于筛选和LC精炼特种产品的建模和模拟。硕士项目将通过模拟纤维和碎屑的轨迹，以及筛分效率和能力的建模，专注于筛筒的设计和优化。创新的高性能纸浆处理系统设计将在中试和工厂规模上进行试验，并随后在加拿大工业中实施，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。这种新的理解将导致先进的气缸设计，确保AFT的长期竞争优势，AFT是一家先进的全球制造公司，在魁北克省舍布鲁克设有主要制造工厂。

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.
