21. Digester modelling for diagnostics and control
Sammanfattning : This thesis will show the possibility for the development and use of an on-line model for application to continuous digesters for pulp production. The model is developed by using a program called Dymola (Dynamic Modeling Laboratory). What makes the Dymola software so well suited is that the program solves equations simultaneously. LÄS MER
22. Optimization of Investments for Strategic Process Integration and Pulp Mill Biorefinery Projects under Uncertainty
Sammanfattning : Energy-intensive industrial plants operate in a changing, uncertain environment. Long-term changes are expected in energy prices, political regulations and technology development. Pulp and paper companies, like many other industries, are under strong pressure to respond to these changes. LÄS MER
23. Study of Paper Dry Strength Additives on Cellulose Fibres
Sammanfattning : Paper packaging is commonly found in the form of paper and cardboard boxes, but recently paper packing is being used in food packaging, trays, beverage packaging and even paper straws, among others. Paper strength additives have been developed to increase the efficiency of the joint strength and the joint areas and potentially maintain bulk in paper products. LÄS MER
24. Analysing different technology pathways for the pulp and paper industry in a European energy systems perspective
Sammanfattning : For the pulp and paper industry (PPI), earlier research has shown that there are many technology pathways, proven and new, available for improvement of energy efficiency and additional sales of (new) products. Some pathways can only be implemented in kraft mills, e.g. black liquor gasification (BLG), but some can be implemented industry-wide, e. LÄS MER
25. Structure-Performance Relations of Oxygen Barriers for Food Packaging
Sammanfattning : Food packaging should ensure the safety and quality of food, minimize spoilage and provide an easy way of storing and handling it. Barrier coatings are generally used to meet the demands placed on fibre-based food packages, as these have the ability to regulate the amount of gases that can enter them. LÄS MER
