Effects of water hardness (CaCl2 addition) on performance of papermaking additives for fine-particle, TAPPI Journal October 2025

Application: A practical take-away message, based on laboratory testing, is that cationic acrylamide-type retention aid is quite tolerant of different water hardness conditions. Such products can promote both retention and drainage in paper machine systems even when operating under very low or very high water hardness conditions, as are often found at mill sites in different regions.

Application of AI-based approach to control the papermaking process, TAPPI Journal March 2025

ABSTRACT: This paper explores AI’s role in revolutionizing the pulp and paper industry, and specifically in predicting wet tensile strength (WTS) for specialty-grade papers. Leveraging eLIXA technology, a 90-day study achieved a 15% reduction in chemical dosage and an 80% decrease in wet tensile standard deviation. The real-time dosage prediction led to optimizing the wet strength resin (WSR) consumption and improved process reliability. The self-learning models exhibited adaptability to changing variables, ensuring their robustness. Overall, this study highlights AI’s transformative impact on efficiency, cost savings, and product quality within the dynamic landscape of papermaking. The approach used for wet strength optimization has been used to optimize other aspects of pulp and paper production.
