Andritz has successfully started up equipment for a fiberline modernization at UPM’s Kymi mill in Kouvola (Finland). This project is part of the mill’s program to minimize effluents and upgrade production capacity. Andritz’s scope of supply included a chip feeding system (TurboFeed) for the continuous digester, an oxygen delignification stage with Drum Displacer washer and knot separation, screening modernization, and modification of the A-stage bleaching process. UPM’s Kymi mill stands for environmentally-friendly integrated pulp and paper production with a high rate of energy self-sufficiency and biofuel usage. The mill produces bleached softwood and hardwood kraft pulp (total capacity 570,000 t/a), as well as coated and uncoated fine paper (830,000 t/a).
