Improved uniformity of the fibers liberated in the kraft pulp digester 

This project sets out to elucidate mass transport characteristics during delignification of wood chips as a means of understanding and controlling non-uniform delignification effects, associated to low efficiency and poor property control in the current pulping processes. To obtain information on local variations of delignification effect in a wood chip, the treated chips will be […]

Controlling product characteristics on board machine utilization process data

Quality on any board and paper products is dependent on being able to maintain low variability within product characteristics. A common problem is that these characteristics are measured cannot be measured online in the production, and is the time resolution will therefor be very low. The product characteristics will be dependent on the process characteristics, where
