TAPPICon 2023 highlights strategies and technologies to make tissue mills more efficient.
energy optimization

As energy costs continue rising at unprecedented rates, reducing energy consumption in mills is more important than ever. More than 70 percent of total energy consumption in tissue machines is consumed in the drying process. Various techniques and tools are now available to help mills optimize their Yankee Hood drying systems and can help provide significant savings.

Alfred Sarli of Valmet will share insight on how a mill can save 10-to-20 percent in energy costs by automating the drying process during his presentation Energy Optimization of the Yankee Hood Air System, on Tuesday, April 25 at TAPPICon 2023 (tappicon.org), April 22—26, in Atlanta, Ga.

“Yankee Hood drying is based on the principle of convective heat transfer in that it depends on both temperature and velocity. Accordingly, total drying costs depend on both the costs of gas and electricity,” Sarli said. “The optimal operating point can be different for every grade and every regional energy cost. Trying to balance this manually is time consuming and requires numerous measurements. The ideal solution is to completely automate the process.”

Attendees will learn more about the Yankee drying process and also hear about the control systems and equipment used in various case studies highlighted during Sarli’s presentation.

TAPPICON 2023—TISSUE TRACK

TAPPICon offers tissue professionals from across the supply chain the opportunity to meet and discuss issues, new advancements/technologies, and strategies for future success. The conference includes a peer-reviewed tissue program featuring a mix of technical content and business insights.

The 2023 tissue program, held Tuesday and Wednesday, April 25 and 26, includes expert-led presentations focused on critical areas of the mill. Sessions include energy, fibers, chemistry and vibration.

ENERGY

In addition to Sarli’s presentation, the energy session explores other key areas to help mills become more energy efficient. Mehail Shekhter, Valmet North America, is scheduled to present “How Can Cogeneration Benefit a Tissue Mill.” Attendees will learn about cogeneration, or combined heat and power (CHP), and its benefits. Shekhter will also explore various CHP types and how CHP can reduce mill energy costs and greenhouse gas emissions.

David Barnard from Industrial Shredders will present “Automating Tissue Waste: The Last Frontier,” which explores various benefits and opportunities of automating the waste removal process. Barnard will share details on how mills can achieve automation, as well as how to minimize safety risks, costs involved, and estimated returns. Attendees will also have the opportunity to hear from Brian Mock, Event Capture Systems, as he shares a case study on “Increasing the Paired Efficiency of Tissue Machine and Converting with Machine Vision.”

FIBERS

Demand for recycled fibers in tissue-making has increased steadily worldwide. This critical resource is the focus of the fibers session at TAPPICon. Attendees will hear from Mrittika Debnath of North Carolina State University as she presents, “Innovating Recycled Fibers Using High-Shear Homogenization for Sustainable Packaging and Hygiene Bioproducts.” Debnath will discuss an alternative approach to old corrugated containers’ (OCC) pulp fibers modification that will enhance fiber and paper properties, such as mechanical strength, without affecting dewatering. Attendees will also learn about a novel approach to circumvent the challenges associated with traditional methods of developing strength properties from OCC, mixed waste, and nonwood fibers as David Zerr of Pulmac Systems International presents “Developing Strength from Recycled Fibers using Micro Fibrillation.” Attendees will hear from Bob Bustin of Oasis Alignment as he presents “Inspection Data is Critical to Planning Dryer Can Adjustments to Solve Wrinkling and Vibration Issues.”

CHEMISTRY

Based on the use of various chemicals and functional additives in the tissue making process, a wide variety of tailor-made properties can be built into the sheet to improve and optimize it. New innovations and process advancements can pave the way to more product opportunities. Attendees at the Chemistry session will hear about a new high-performance Yankee coating adhesive for TAD and hybrid-TAD tissue and towel machines. During his presentation “New Simplified High-Performance Yankee Coating for Advanced Machine,” Jia-Yu Wang of Nalco Water, an Ecolab Company, will share how a new single, high-performance adhesive produces super adhesion from a soft, durable film that has improved film uniformity and thickness.

Polyamidoamine epichlorohydrin (PAE) resins have been a predominant chemistry used for generating wet strength in towel grades for more than 50 years, but there are several downsides to their use, including increased regulatory scrutiny due to harmful chloro-organic byproducts present in the resin. Lucyna Pawlowska of Kemira will share insight on a more effective and cleaner alternative to PAE resins during her presentation, “Wet Strength Alternative for Towel Grades.” Attendees get details on how this alternative, glyoxalated polyacrylamide (GPAM) resin provides wet strength permanency close to that achieved with PAE resins, as well as dry strength, improved repulpability, and no chloro-organic impurities.

VIBRATION

While vibration monitoring systems that monitor the tissue creping process have been around for over 10 years, recently it has been realized that vibration monitoring can provide additional insight into the overall creping unit operation. It is a valuable tool for the tissue maker to understand and track in real-time the impacts of mechanical, operational, and chemical (MOC) changes to the creping operation. Gary Furman of Nalco Water, an Ecolab Company, will share details about a new digital tool called Yankee Operations Intelligence used for monitoring and providing unique insights into the creping process during his presentation “Introducing Yankee Operation Intelligence—A Next Generation Crepe Blade Vibration Monitoring Tool.”

Vibration monitoring is also important for maintenance and reliability engineers to identify mechanical problems early, keeping machines running and plants operational. Successful condition monitoring depends on field-proven vibration monitoring best practices. Mills can learn about these best practices during Tom LaRocque’s, Wilcoxon Sensing Technologies, presentation “Best Practices: Vibration Monitoring of Pulp & Paper Production Assets.”

THERE’S MORE…

In addition to these presentations, attendees can gain a greater understanding of the surface modification of lignocellulosic fibers to reduce hard-to-remove water and its effect on the properties of tissue and hygiene products. Hasan Jameel of North Carolina State University (NCSU) will present “Sustainable Surface Modification Strategies for Upgrading Softness and Tensile Properties of Lignocellulosic Fibers.” They can hear Lokendra Pal, also of NCSU, share the results of a study on sustainable alternative fibers that show better exhaustion than commercial wipes and textile fibers during his presentation “Understanding of Quat Binding with Cellulosic Fibers and Wipes for Sustainable Hygiene Product Developments.”
