ABB has launched L&W Fiber Online – a reliable, repeatable and cost-effective online system for measuring, monitoring and controlling significant fiber quality variables in paper stock preparation and pulp production.
This helps pulp and paper customers to save production costs by optimizing fiber 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 fiber images provided by L&W Fiber Online provide a more detailed and accurate information on the status of pulp quality. Fiber 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 fiber 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.
