Fractionation of chemical pulps for the development of 'Next-Generation' pulp and paper products

增强型、多阶段纤维分级是“下一代”纸浆和纸产品开发中的一项具有变革性的技术。这项拟议的研究计划将包括广泛的实验调查，以确定纸浆压力筛和水力旋流器的设计和操作如何影响纤维特性分布(纤维长度、壁厚和直径)的变化。通过广泛的实验研究，将开发出分离过程的详细模型，并将其应用到过程模拟技术中。该模型将基于对这些单元操作中的纤维运动的基本理解。由此产生的模拟将用于设计未来的多级分馏系统，该系统将在整个加拿大工业中使用。

Enhanced, multi-stage, fibre fractionation is an enabling, transformative technology in the development of 'next generation' pulp and paper products. This proposed research program will include an extensive experimental investigation to determine how pulp pressure screen and hydrocyclone design and operation affect the change in fibre property distributions (fibre length, wall thickness and diameter). From the extensive experimental study, a detailed model of the separation process will be developed and implemented into process simulation technology. The model will be based on the fundamental understanding of fibre motion within these unit operations. The resulting simulation will be used to design future multi-stage fractionation systems that will be used throughout the Canadian industry.
