Paper360 Better Together Podcast Series
Live from TAPPICon 2023: Episode 1

TAPPICon 2023 was a huge success with attendees and exhibitors. Boasting high attendance and a top-notch program, the conference offered plenty for attendees, including a multi-track technical program and an exhibit floor packed with new technology.

Better Together Host Jan Bottiglieri was at TAPPICon interviewing exhibitors and attendees to capture some of that energy live, while it was happening. For this special "Live from TAPPICon 2023!" episode, she's joined by guest host Mark Rushton, senior editor with Paper360° and the editor of Tissue360°.

Here are the folks you'll meet on this episode of "Better Together"-- and just a taste of what they'll be sharing in their conversations:

  • Jeff Peters, BTG: "The biggest growth (in the tissue sector) has been through improvements in tissue technology."
  • Alfredo Sarli, Valmet: "Tissue is one of the most energy intensive processes... but that creates opportunity."
  • Naomi Ballenger, Jacobs: "We've set up employee networks that help employees feel ready to make that next move up."
  • Pat Dixon, Pulmac: "Say you have a Z-Span tester or a shive analyzer—you're producing data, but what do you do with it?"
  • Yesha Patel, JMC Paper Tech USA: "As a company new to the NA market, we offer our own strengths... this industry will continue to grow."

Even if you missed TAPPICon this year, this episode will let you virtually join the nearly 1,700 industry professionals, students, and others who gathered to learn and network in Atlanta. Make sure to subscribe and share—and join the conversation on Better Together!

STAR of the Month

TAPPI TIP 0416-15: Chloride and potassium measurement and control in the pulping and chemical recovery cycle

Scope: Considerable research and operating experience have established industry acceptance that limiting chloride and potassium concentrations in the pulping and recovery cycle liquors is necessary to achieve recovery boiler capacity and high availability. Lowering the concentration of Cl and K in as-fired black liquor will result in ash deposits formed on boiler heat transfer surfaces that are controllable by sootblower operation alone. An equally important reason for limiting the concentration of K especially is the need to maintain the first melting temperature of deposit below the surface temperature of the superheater tubes. This Technical Information Paper (TIP) will provide an understanding of the sources of chloride and potassium in the mill cycle and their effect on carryover particles and fume in the recovery boiler, the steps that can be taken to develop a mill material balance and determine the maximum acceptable concentration of these in the precipitator ash, and the various approaches that can be applied to limit the concentrations. Ash produced in recovery boilers contains mainly alkali sulfates, carbonates and some chloride compounds, this TIP will provide some basic information on the fate of these materials in removal systems. Processes are described that are available and are being developed to remove chloride and potassium from the cycle with sufficient detailed information to permit an operating mill to make a preliminary evaluation of the most suitable process (1).
