Determination of Lignin in Non-Wood Plant Fiber Sources

Thermomechanical Pulping of Loblolly Pine Juvenile Wood

Intensive forest management, with a heavy emphasis on ecosystem management and restoring or maintaining forest health, will result in the removal of smaller diameter materials from the forest. This increases the probability of higher juvenile wood content in the harvested materials. The purpose of this study was to compare the performance of loblolly pine juvenile and mature wood unbleached the...

TAPPI JOURNAL PEER REVIEWED PAPER Analysis of pulping data using the self-organizing map

Analysis of process data makes it possible to obtain useful information of processes or phenomena that are analytically difficult to deal with. To demonstrate the possibilities of this kind of approach, an analysis of the faults that occurred in a continuous digester is presented. The process data are fed to an artificial neural network, the Self-Organizing Map (SOM), which is used to form visu...

Wood and Fibre Mechanics Related to the Thermomechanical Pulping Process

The main objective of this thesis was to improve the understanding of some aspects on wood and fibre mechanics related to conditions in the thermomechanical pulping process. Another objective was to measure the power distribution between the rotating plates in a refiner. The thesis comprises the following parts: – A literature review aimed at describing fracture in wood and fibres as related to...

Wood Processing and Pulping Process (fwm 504) Logging

Logging industry is a fast-growing business regardless of the many risks involved. The procedures used to harvest wood are tree-length, full-length and cut-to-length logging. Choosing one over the other is simply a matter of choice since there are advantages and disadvantages with each of the various methods. The removal of too many trees from the forest can cause environmental hazards as well ...
