6. Viscous Behaviour of Fibre-filled Liquids
Sammanfattning : Process simulation of discontinuous fibre composites is of importance in automotive industries. The performance of a fibre composite part depends to a great extent on the fibre orientation pattern. LÄS MER
7. Lime Mud Reburning. Properties and Quality of the Lime Produced
Sammanfattning : It is of utmost importance that the white liquor used in the digester of a sulphate pulp mill is of high quality. The white liquor is prepared in the causticizing plant, through causticizing of the sodium carbonate in the green liquor. LÄS MER
8. Bio-coal for the sustainable industry : A scientific approach to optimizing production, storage, and usages
Sammanfattning : Bio-coal produced from biomass is a promising material to replace fossil coal in order to achieve net-zero greenhouse gas emission from the industrial sector. Bio-coal with quality comparable to that of fossil coal can be produced by high-temperature pyrolysis at ≥500 ºC, but the production efficiency is relatively low due to low bio-coal yield at high pyrolysis temperatures.

9. Degradation of mullite based materials by alkali containing slags
Sammanfattning : Iron is one of the most important resources that can be found in the lithosphere; 90 % of all metal ores extracted are iron ore. Many steps are included in the extraction from iron ore to metallic iron, where the processes vary between different producers. Iron ore pellets, are a prepared burden material for ironmaking in the blast furnace. LÄS MER
10. Towards better understanding of the flow inside industrial processes: a CFD study
Sammanfattning : Computational Fluid Dynamics (CFD) is a method to numerically pre- dict flow patterns. In this thesis the method is used to predict the flow in a hydrochloric acid regeneration plant located at SSAB EMEA in Borl ̈ange and to investigate the flow in a burner region of a rotary kiln at LKAB in Kiruna.
