Continuous digester rapid thinning, TAPPI Journal June 2024
ABSTRACT: Carbon steel continuous digesters built after the early 1980s are fully stress relieved, so stress corrosion cracking has been less of a concern. However, these newer digesters were designed to run modified cooking processes that have turned out to be much more corrosive than those running with conventional cooking. This corrosion is mainly associated with softwood digesters and appears to be flow related. Average corrosion rates of 40 mil/year are possible on the exposed shell between the wash and extraction screens. The corrosion patterns are visually distinct from surfaces in the upper digester and below the wash screens. This paper goes into practical detail on where it occurs, the causes, visual identification, inspection planning and results evaluation, and finally, how to mitigate this damage, which consists of applying a corrosion resistant barrier. Some discussion on dealing with general corrosion throughout the digester is included.

Editorial: Looking forward, looking back, TAPPI Journal January 2022
ABSTRACT: Much like 2020, 2021 was another year of remarkable highs and lows delivered by the COVID-19 pandemic. Vaccines, variants, and infection surges altered the way we behaved personally and professionally last year. As we move into 2022, we are now grappling with health and business concerns from the omicron variant that has overwhelmed hospitals in some areas and contributed to a global supply chain crisis. The ability to adjust has once again become a key skill in adapting to our shifting “new normal.”

Editorial: Special issue showcases new additive approaches for a lignocellulose-based future, TAPPI Journal January 2024
ABSTRACT: Lignocellulose-derived materials are inherently renewable and are of benefit not only through their recyclability and biodegradability, but also from carbon sequestration during the production of the base raw material. With regulatory agencies tightening restrictions and consumer habits slowly shifting, the paper industry is well positioned to fill a market need for renewable bio-based materials. Although the inherent benefits of lignocellulose-based products are many, all too often, the end-product does not meet the required performance or cost in use desired by end-users. This creates obstacles for a more renewable economy that relies less on petroleum-derived products.
