  1. 1. Models for Wet Scrubbing of SO2 and NOx

    Författare :Charlotte Brogren; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; limestone scrubbing; wet scrubbing; absorption; WFGD; flue gases; SO2; mass transfer; NOx; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    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

  3. 2. Application of DOAS for Studies of Evolving Volcanic Activity in Central America

    Författare :Alexander Vladimir Conde Jacobo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RSAM; seismic events; UV-scattered sunlight; gas scrubbing; sulphur dioxide; DOAS;

    Sammanfattning : Volcanic gas emissions play a critical role in understanding the physical processes that drive eruptive activity. Combining gas measurements with other geophysical parameters provides a more accurate description of the changes that occur beneath a volcano. LÄS MER

    Sammanfattning : A great deal of research is being carried out on the biological production of hydrogen and methane. However, little effort has been devoted to studying the technical and economic feasibility of these processes. LÄS MER

  5. 4. Porous Sorbents for Environmental Applications and Selective Laser Sintering 3D Printing of Dosage Forms

    Författare :Michelle Åhlén; Ocean Cheung; Maria Strömme; Jonas Lindh; Christel Bergström; Carlos Grande; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metal-organic frameworks; zeolitic imidazolate frameworks; mesoporous magnesium carbonate; greenhouse gas capture; adsorption; adsorption kinetics; additive manufacturing; selective laser sintering; personalized medicines; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : The rising levels of greenhouse gas emissions from vehicular and industrial pollution constitute a serious concern not only for the environment but for our entire society. Traditional gas capture and separation techniques, such as amine scrubbing for CO2 gas separation, have been commonly used at a commercial scale, however issues relating to high costs and high energy requirements for sorbent regeneration have limited the efficiency of many of these techniques.

  7. 5. Advances in droplet evaporation

    Författare :Giandomenico Lupo; Christophe Duwig; Sébastien Tanguy; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Droplet evaporation (and condensation) is one of the most common instances of multiphase flow with phase change, encountered in nature as well as in technical applications. Examples include falling rain drops, fogs and mists, aerosol applications like electronic cigarettes and inhalation drug delivery, and engineering applications like spray combustion, spray wet scrubbing or gas absorption, spray drying, flame spray pyrolysis.
