Abstract:

Alabama Center for Paper and Bioresource Engineering is developing a technology to advance the drying process in the paper manufacturing. This topic is extremely important from the energy consumption and sustainability perspective. Paper drying accounts for some 80% of the energy that is used for paper making. The main process used for drying is vaporization. This technique has high energy requirements and thus energy and cost effectiveness of different physical means of dewatering can potentially far exceed the process of vaporization drying. Therefore a novel method of improving significantly the physical dewatering process has been developed. In theresearch it was discovered that the additions of hydrophobic fibers to the pulp furnish can bring major benefits to the drying process. From the author?s research it can be shown that the addition of hydrophobic fibers at even a few weight percent may have a major impact on the freeness and water retention properties of the furnish. These preliminary results are very encouraging and therefore we continue to develop this novel concept aiming at significantly improving drying effectiveness and related economic savings in the physical dewatering of webs made using hydrophobically tailored furnish material.
