maker to deliver continuous process improvement by using autonomous chemistry control through its secure Optix Applied Intelligence artificial intelligence (AI) platform. Developed with ProcessMiner, a leading AI platform, the adaptive analytics system accurately learns complex variable relationships in pulp and paper manufacturing processes and yields a digital measure of product quality. Autonomous manufacturing using AI with machine learning is a means to improved product quality, optimised use of raw materials and reduced water and energy consumption. Applied at the Baileyville mill of St Croix Tissue in Maine, Optix has enabled a closed- loop controller in conjunction with Optix quality parameter predictions to control strength chemistry autonomously to ensure the optimum chemical feed and adhere to target parameters. “Optix has shown that it can

reasonably predict different lab-tested parameters,” said Devin Rose, technical manager at St Croix Tissue. “We’ve used this prediction in a closed-loop controller and successfully reduced variation in the final product. As a result, we’re excited about the value of this programme.” Launched by Solenis in 2019,


the Optix platform is operational in nine paper mills in North America and Europe, with more


to come. Using AI-powered predictive analytics of key quality parameters allows for on-the-fly process improvement, real-time process insights and continuous chemical control, leading to improved adherence to targets, better product quality and substantial cost savings. “Solenis continues to deliver


innovative solutions that solve the complex problems that exist in the pulp and paper industry,” said Andreas Türk, president


for Eurasia at Solenis. “Our partnership with ProcessMiner enables us to uniquely deliver the cutting-edge artificial intelligence and machine learning technology required for real-time, predictive analytics and autonomous manufacturing. “Our latest Optix offering,


autonomous chemistry optimisation, is another example of Solenis delivering the value our customers need to stay competitive.”


Low-pressure glue pumps for use on core-winders


With many years of experience in supplying adhesive dispensing systems for the tissue, pulp, and paper industries, Spain’s Valco Melton offers low-pressure glue pumps for use on core-winders. The company says that the output pressures generated by the more expensive piston pumps are unnecessarily

oversized for core winding. Adhesives commonly used in this process contain solids that may damage the pump seals and reduce their lifespan resulting in increased machine downtime and complex maintenance tasks. Diaphragm pumps however


are an excellent alternative to piston pumps offering numerous benefits. Low-pressure pumps


work with all kinds of adhesives with minimal wear and are said to require less maintenance resulting in a more cost-effective option. The DD-1 diaphragm pump


features an electronic-reversing mechanism that enables the pump shaft to creep slowly and avoid stroke stalling. More information from www3. valcomelton.com
