1. Chemometric and signal processing methods for real time monitoring and modeling : applications in the pulp and paper industry
Sammanfattning : In the production of paper, the quality of the pulp is an important factor both for the productivity and for the final quality. Reliable real-time measurements of pulp quality are therefore needed. LÄS MER
2. On calcium-related problems in kraft pulping of Eucalyptus dunnii
Sammanfattning : Kraft pulping is the most widely used pulping process for producing chemical pulp today. It has been in use for more than 130 years. LÄS MER
3. Aspects of extended impregnation kraft cooking for high-yield pulping of hardwood
Sammanfattning : The long-term trend regarding wood is an increase in price. Because wood contributes to a large part of production costs, the efficient utilisation of wood is greatly desired to reduce production costs for kraft pulp producers. During the 1990s, the development of improved modified kraft cooking began, which led to higher yields. LÄS MER
4. Optical Studies of Bio-inspired Materials for Camouflage
Sammanfattning : In the ongoing sensor-camouflage duel, new functionalities and sensing abilities are continuously incorporated in detector devices, requiring new capabilities on the camouflage side. The aim of this work is to contribute to improved camouflage including low polarization detectability in wavelength regions with both visible and invisible light. LÄS MER
5. Wood chips for kraft and sulfite pulping : evaluation of novel forest-industrial drum-chipping technology
Sammanfattning : Wood chipping and the supply of high-quality wood chips are of critical importance for most forest-industrial processes. The quality of wood chips affects product yield, product quality, and processability. LÄS MER
