Computer Application for Pulping Process

Process intensification in mechanical pulping

Process intensification is a term used in the chemical process industry for major improvements in the process design leading to radical changes in process complexity, equipment size and efficiency. We suggest that a similar approach is applied in the pulp and paper industry. We have focused on the production of mechanical pulp, but a similar approach can be applied to other areas within the pul...

SOM Based Analysis of Pulping Process Data

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 ...
