ONLINE SYSTEM FOR MONITORING FIBER PROPERTIES • L&W Fiber Online expands ABB’s offering for pulp measurements to help improve quality and reduce costs for paper producers
• Compared with other traditional indirect measurements, L&W Fiber Online provides paper makers with complete information on fibre properties, refining effect and fibre mix, to help them monitor and control pulp quality ABB has launched L&W Fiber Online – a reliable, repeatable and cost-effective online system for measuring, monitoring and controlling significant fibre quality variables in paper stock preparation and pulp production. This helps pulp and paper customers to save production costs by optimizing fibre usage, as well as reducing energy consumption through elimination of over-refining, and to improve quality by generating uniform pulp furnish for the paper, board or tissue machine. Compared with traditional indirect measurements such as Canadian Standard Freeness (CSF) and Schopper-Riegler (SR),
the measurements based on fibre images provided by L&W Fiber Online provide a more detailed and accurate information on the status of pulp quality. Fibre properties are categorized and presented as mean values and statistical distributions of width, length, shape factor, two classes of fines (P and S) and macro fibrillation. L&W Fiber Online mitigates the problem of detecting late in the production process quality issues caused by fibre variations. By discovering variations earlier in the process, and as early as in stock preparation, it becomes feasible to take corrective actions in time to produce paper, board or tissue that meets the specifications. This system is based on ABB’s well - known L&W Fiber Tester Plus, a laboratory instrument which is used by hundreds of papermakers to track their pulp quality, and is a preferred tool by research centres and universities around the world. The system also allows for multiple sampling points with a single instrument, reducing initial investment and ongoing maintenance costs. For mixed furnishes, the optional Blend software analyzes the ratio of reference fibre species in a fibre mix, making it possible to save raw materials when switching grades or during start-up. “We can now offer a robust unit that tells the complete story of the fibres in real time, which gives our customers an easy way to pinpoint and follow trends on furnish quality, and at the same time help them to reduce variations in stock preparation or pulp production, as well as saving energy” says Anna Schärman, Global Product Manager, ABB Pulp & Paper products. http://new.abb.com
