项目摘要

In this collaborative project, Dr. Fatehi of Chemical Engineering Department at Lakehead University along with Mr. Kelertas and Mr. Dokis of Resolute Forest Products will investigate the production of flocculants from lignin that is extracted from the tall oil production process of the Resolute Forest Products mill in Thunder Bay, ON. In tall oil production process, crude tall oil is produced via acidulation of tall oil soap that is separated from black liquor of the kraft pulping process. Lignin and spent acids are the by-products of the tall oil production process. They are sent back to the evaporators of the kraft process and mixed with black liquor for burning. In this proposed CRD project, the opportunities for producing flocculants from lignin of the tall oil process is evaluated. Various innovative pathways will be examined to produce flocculants from lignin and the most compatible process with the tall oil production process will be evaluated in detail for facilitating its adaptation and commercialization in the kraft process. The produced flocculants are proposed to be used in water and wastewater purification of the mill (i.e., internal uses) as well as in municipal wastewater, thickeners and waste treatment facilities of the mining industry (i.e., external uses). Dr. Fatehi and Resolute's staff will collaborate closely on a bimonthly basis so that the developed technology can be adapted and practically implemented into the existing facilities of Resolute's mill in Thunder Bay. This new process will assist Resolute's mill in increasing its revenues and reducing its overall operation costs. Meanwhile, it will enable Dr. Fatehi to investigate the fundamentals associated with the application of lignin-based flocculants in wastewater systems and to be the pioneer in developing lignin-based value-added products. The production of lignin-based flocculants is a pathway to establish kraft-based biorefinery, which will increase and diversify the revenues of kraft pulp mills across Canada.
在这个合作项目中,湖首大学化学工程系的Fatehi博士与Resolute Forest Products的Kelertas先生和Dokis先生将研究木质素的絮凝剂生产,木质素是从位于安大略省Thunder Bay的Resolute Forest Products工厂的高油生产过程中提取的。在塔尔油生产过程中,从硫酸盐制浆过程的黑液中分离出塔尔油皂,通过酸化生产塔尔油。木质素和废酸是高油生产过程的副产物。它们被送回卡夫工艺的蒸发器,与黑液混合燃烧。在这个建议的CRD项目中,评估了用高油工艺的木质素生产絮凝剂的机会。将研究从木质素中生产絮凝剂的各种创新途径,并详细评估与塔尔油生产工艺最相容的工艺,以促进其在硫酸盐工艺中的适应性和商业化。建议将生产的絮凝剂用于磨厂的水和废水净化(即内部使用)以及矿山的城市污水、稠化剂和废物处理设施(即外部使用)。Fatehi博士和Resolute的员工将在两个月的基础上密切合作,以便开发的技术可以适应并实际实施到雷索贝Resolute工厂的现有设施中。这一新工艺将有助于Resolute的工厂增加收入,降低整体运营成本。同时,它将使Fatehi博士能够研究与木质素基絮凝剂在废水系统中的应用相关的基础知识,并成为开发木质素基增值产品的先驱。以木质素为基础的絮凝剂的生产是建立以牛皮纸为基础的生物炼制的途径,这将增加和多样化加拿大牛皮纸纸浆厂的收入。
