1. Application of dispersive UV-visible absorption spectroscopy for in-situ detection of gaseous pollutants in flue gases
Sammanfattning : .... LÄS MER
2. Modeling of Gas Flows in Steelmaking Decarburization Processes
Sammanfattning : The purpose of the current study is to increase the understanding of different steelmaking processes at the decarburization stages by use of mathematical modeling. More specifically, two De-Laval nozzles from a VOD (Vaccum Oxygen Decarburization) process, which is used for producing stainless steels with ultra-low carbon grades, was investigated for different vessel pressures.

3. Models for Wet Scrubbing of SO2 and NOx
Sammanfattning : Combustion of fossil fuels is the main source for emissions of sulfur dioxide and nitrogen oxides. Emission regulations and the growing environmental awareness will make great demands upon cost-effective deSO2 and deNOx techniques in the future. LÄS MER
4. Numerical Simulations for Studies of Unsteady Combustion in Practical Combustion Devices
Sammanfattning : A major problem in the design of combustion equipment is to prevent the occurrence of combustion instabilities. Combustion instabilities appear as periodic oscillations in pressure and heat release through a feedback mechanism between the fluid dynamics and the combustion process. These oscillations may induce e.g. LÄS MER
5. Absorption Based Systems for Co-removal of Nitrogen Oxides and Sulfur Oxides from Flue Gases
Sammanfattning : Enhanced control of nitrogen and sulfur emissions, found in many of industrial processes, is anticipated for decades to come. Stricter emission regulations require new technologies adapted to the new conditions at reasonable cost. LÄS MER
