Improving monochloramine performance with innovative sensor-controlled dosing, TAPPI Journal January 2024
ABSTRACT: Monochloramine (MCA) has become one of the major oxidant chemistries for biological control in the paper industry. Feedback control, such as oxidative-reductive potential (ORP), is often used to provide better control of a dosing scheme. The trademarked Ackumen MCA-i is a chemical-digital solution that uses artificial intelligence with actionable insights to stabilize the wet-end process, providing improved performance and reduction in overall chemical costs. Accurate sensor-controlled dosing can be tied to multiple inputs, such as production rates, grade changes, pH, ORP, chlorine residual, freshwater usage, and more. In this study, a case history will be presented to demonstrate how this technology provided a more consistent MCA molecule throughout the process, resulting in a higher level of efficacy and reduction in chemical costs.

Editorial: TAPPI Journal goes Open Access in 2020, TAPPI Journal October 2019
ABSTRACT: Scientific publishing has changed significantly since the 1990s with the evoluation of the internet, which has largely migrated journals from subscription-based print publications to online content like eBooks, portable document formats (PDFI's), and web-based HTML files. Along with these changes in format has come a growing trend for online journal content to be either partially or fully "Open Access" (OA) so that more institutions and individuals can take full advantage of scholarly literature without a subscription of society membership status.

Nanocellulose in Japan: An industrial perspective, TAPPI Journal April 2019
ABSTRACT: With the maturing of Japan’s economy, domestic demand for paper and paperboard is more likely to level off in the long term. Japanese paper companies are accelerating overseas production, especially in the emerging Asian markets, while strengthening competitiveness of domestic mills and developing new products. In Japan, we have always focused on emerging technologies and driving innovation in the pulp and paper industry. As a business definition, innovation does not equal innovative technology. Innovative technology can become innovation only when it is commercialized and used in industry.

Real-time monitoring of bubble size distribution in a foam forming process, TAPPI JOURNAL August 2019
ABSTRACT: Foam forming is an intricate option to lessen fiber flocculation and to get better energy and water efficiency when making fiber-based products. Developed during the 1970s, this approach has recently received renewed attention, mainly because it also offers possibilities to widen the fiber-based product portfolios with novel and more valuable products. In addition to air content, bubble size is the most important property of foam. Foam quality control is essential for building real-world foam forming processes. In this work, we show how bubble size can be monitored with direct optical imaging in real time in real process conditions, and how such analysis helps adjust foam quality and discover process faults in foam forming.

Editorial: Let's talk tissue!, TAPPI Journal July 2019
ABSTRACT: In this issue of TAPPI Journal (TJ), researchers Olejnik and Pelczynski of Lodz University of Technology in Poland and researcher Bloch of the University of Gre-noble Alpes in France use an experimental device to measure the liquid absorption properties of tissue (p. 417). The device, called the eXtended liquid penetration analyzer (XLPA), was initially built at the Institute of Papermaking and Printing at the University of Lodz. Results from the study published here showed that the XLPA measurements were in good agreement with the ISO 12625:-8:2010 standard measurements. The researchers believe this method could ultimately help mills characterize the liquid absorption of their tissue in a better and faster manner.

Large data set analysis to determine refiner plate total cost of ownership, TAPPI Journal June 2019
ABSTRACT: Efficient process data storage and its subsequent analysis are vital to the profitable operation of a paper mill. An evaluation of refiner plate performance was conducted for an integrated paper mill. Trials with two new plate patterns were compared with the incumbent pattern; the goal was to increase refiner plate life. Plate life increased with both new design patterns, and the mill selected one of the two new choices. However, addi-tional impacts to paper machine performance and mill maintenance costs were not considered in the selection deci-sion. A large data set analysis tool was used to identify unrealized savings of 1.5% with reduced fiber usage (basis weight) on the paper machine’s most prevalent grade. The large data analysis indicated that this unrealized benefit with the alternate plate design was not attainable with the chosen plate design.
