KENTARO TAJIRI AND THOMAS WISCHEROPP For years, Klingele Papierwerke in Weener, Germany, had suffered from less than ideal conditions on its first top dryer fabric, including short fabric life and serious sheet moisture profile variation. The mill had used “spot cleaners” and off-line washes, yet was not satisfied with running and maintenance costs and the detrimental effect of stickies on ...

RAMAZAN ATAMAN At Mondi’s Dynäs mill in Väja, Sweden, mechanical problems and high maintenance costs proved that the drive system on PM 6 needed a rebuild. Mondi Dynäs PM 6 produces sack kraft paper with basis weight ranges from 50–160 g/m2 and a web width of 6,500 mm. In 2014, the machine speed was 775 m/min. Before the rebuild, the ...

VIPIN SUMANI AND THOMAS S. SEGULJIC The pulp and paper industry is one of the heaviest users of water in the US, using almost 15,000 gallons of water per ton of finished product. With water used in nearly every step of the production process, the large volumes of wastewater and residual sludge waste present treatment, discharge and disposal issues. Coupled ...

New scanning sensors, soft sensors, open-ended multivariable control, and the first steps to integration with web inspection are expanding the definition of quality control. MARK WILLIAMSON It’s been almost 50 years since the first computer-based paper machine quality control systems hit the market. Over the intervening years, a lot has happened to advance the scope and effectiveness of the measurement ...

JENNIFER BAILEY As the world’s need for clean, sustainable water sources continues to increase, so does the need for industrial operations to reduce freshwater intake and to efficiently treat wastewater before it is released back into the environment. Pulp and paper manufacturers, as participants in a particularly water-intensive industry, have a special responsibility to control and optimize water use throughout ...

DOUG SWEET, P.E. Vacuum systems are essential for papermaking. They contribute to sheet formation and dewatering, press performance, felt conditioning, and general machine efficiency. The vacuum system includes several sub-systems for vacuum control, air/water separation, and vacuum pump seal water management. Generally, paper machines operate with little attention required of the vacuum processes. Yet these systems tend to evolve into ...
