Press Section Grinds

This study explores the potential benefits of enhancing the geometric tolerances of press roll sections in paper mills. Results over 17 months revealed reduced cross-direction moisture variations by 19.08% and an 18 feet-per-minute increase in machine speed. Interestingly, there was a 25.10% decrease in vacuum usage in the pick-up felt uhle box, hinting at less water removal necessity. Further research will delve into the implications on felt life.

Novel Biofilm Control Technology

ARTIGOS PUBLICADOS

The paper manufacturing sector seeks solutions to control pink slime growth without the corrosive side effects of chlorine-based biocides. A university collaboration identified a molecule, B11, showing promising biofilm inhibition. With a minimal dosage of 0.05 mg/l, B11 offers greater effectiveness than current organic biocides. This breakthrough presents an opportunity to safely and effectively manage biofilm while mitigating corrosion risks in machinery.

Impact Of The Recycling Process On Kraftliner Paper

ARTIGOS PUBLICADOS

The study assessed the effects of recycling on eucalyptus short fibers like Eukaliner® compared to 100% pine long fibers. While both fibers experienced property reduction through recycling cycles, eucalyptus fibers showed better preservation and required less refining energy. Both met the CCB2022 document values for testliner papers, emphasizing the cost-effective and sustainable potential of eucalyptus fibers in paper production.

Análise De Cenários Em Uma Planta De Evaporação

ARTIGOS PUBLICADOS

O estudo aborda a análise de cenários em uma planta de evaporação de fábrica de celulose kraft, utilizando um modelo computacional baseado em dados reais. Foram investigados três cenários e, com base nos indicadores-chave, os modelos permitiram uma avaliação rápida e segura, destacando a relevância de tais análises no contexto da Transformação Digital.
