A New Tool to Measure and Track Fiber Properties and Experiences from Installations in Pulp Mills

摘要

Södra Cell, the leading market pulp producer in Europe, has on-line measurements of fiber properties installed inrnall production lines in the four Scandinavian mills for production of bleached chemical pulp. The main purposesrnfor the installations were to secure the quality delivered to the customers by more frequent tests of quality, byrnnew important fiber properties and by control of transitions in the mill. The system is also used for qualityrnoptimization of wood supply and process. L&W STFI Fibermaster from Lorentzen-Wettre is a platform for pulprnquality measurements. Measured properties are fiber length, width, shape factor, fines, coarseness, bendability,rnshives and freeness. The new technology admits new and more frequent measurements of pulp quality.
