ABB L&W Fiber Online monitors fibre properties
August 1, 2017 By P&PC Staff
Aug. 1, 2017 – ABB has launched L&W Fiber Online, describing it as a reliable, repeatable and cost-effective online system for measuring, monitoring and controlling fibre quality variables in paper stock preparation and pulp production.
According to ABB, the system will help pulp and paper customers save production costs by optimizing fibre usage, reduce energy consumption through elimination of over-refining, and timprove quality by generating uniform pulp furnish for the paper, board or tissue machine. The measurements based on fibre images provided by L&W Fiber Online promise to provide 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. ABB says 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, it explains. The system also allows for multiple sampling points with a single instrument, reducing initial investment and ongoing maintenance costs.
