Wet-end runnability issues? FPInnovations’ portable infra-red moisture sensor to the rescue!

When machines at pulp and paper mills have wet-end runnability issues such as web breaks and non-uniform profiles, this often causes quality and runnability issues at the machine itself and at end-user. To understand the root causes of these problems, it is sometimes necessary to look at the wet-end moisture profile uniformity. To that end, FPInnovations has developed a technique using a portable infra-red (IR) moisture sensor that measures and analyzes moisture profile in cross-direction content at the wet-end of paper, board, or pulp machines.

Unbleached pulp versus bleached pulp-ft

FPInnovations’ newest measures to identify cost reduction opportunities for kraft mill unit operations

It is no secret that kraft fibreline equipment in North American kraft mills is getting old. Mills are upgrading their machines and looking for ways to improve their operations to become more efficient and cost-effective. To stay competitive against state-of-the-art operations around the world, new bleaching strategies and solutions for aging kraft pulp mills are crucial. In addition, the complexities of kraft fibreline chemistry can sometimes lead to severe bleachability issues and increased costs. To help kraft pulp mills maintain a stronghold in the market and address their issues, current research on fibreline chemistry by FPInnovations’ Shree-Prakash Mishra and the Pulp and Paper Manufacturing – Chemical Process team has been focusing on each stage of the bleaching process.
