1. Drying of iron ore pellets : analysis with CFD
Sammanfattning : Iron ore pellets are a highly refined product and for companies such as LKAB it is important to constantly improve the pelletization in order to enhance production and improve product quality. A long term goal has been established to develop and considerably refine tools and techniques with which the drying zone of a pelletizing plant can be optimized. LÄS MER
2. Modeling drying of iron ore pellets
Sammanfattning : Iron ore pellets are a highly refined product supplied to the steel making industry for use in blast furnaces or direct reduction processes. The use of pellets offers many advantages such as customer adopted products, transportability and mechanical strength yet the production is time and energy consuming. LÄS MER
3. Managing agricultural nutrient leaching within the EC Water Framework Directive in Sweden
Sammanfattning : Agricultural management practices geared towards reducing nutrient leaching are in focus for the research presented in this thesis. Critical measures for reducing diffuse pollution from the agricultural sector depend on decisions of individual farmers. LÄS MER
4. Towards 3D modelling of Compression Moulding of SMC
Sammanfattning : The automotive industry is facing ever increasing demands for reduced emissions, and lightweight solutions are thusly required. One field that has significant potential in this regard is composite materials, which can offer a good combination of weight reduction and mechanical properties. LÄS MER
5. Development of flue gas treatment for small-scale boilers with a focus on particulate matters purification
Sammanfattning : Small-scale boilers significantly contribute to particle matter (PM) emissions, which adversely affect health and global warming. According to World Health Organization, particulate matter was ranked as the fifth significant parameter in premature death in 2015. LÄS MER
