  1. 1. Emissions from Fires Consequences for Human Safety and the Environment

    Detta är en avhandling från Department of Fire Safety Engineering and Systems Safety, Lund University

    Författare :Per Blomqvist; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kontroll av utsläpp; pollution control; Miljöteknik; Environmental technology; Byggnadsteknik; Building construction; incapacitation; CFD; simulations; emissions; particles; dioxin; PAH; gases; quantitative analysis; fire effluents; chemical characterisation; large-scale experiments;

    Sammanfattning : Accidental fires represent a risk for people from the heat and fire effluents produced. It is clear from fire statistics that it is, in fact, the toxic gases that kill and injure many fire victims. Further, there are a number of compounds that are readily produced in fires, which have important sublethal effects on humans. LÄS MER

  2. 2. Assessment of safety characteristics for Li-ion battery cells by abuse testing

    Detta är en avhandling från Department of Fire Safety Engineering and Systems Safety, Lund University

    Författare :Carl Fredrik Larsson; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; overcharge; Lithium-ion; toxic gases; abuse test; thermal runaway; short circuit; safety; battery; fire;

    Sammanfattning : Despite the many advantages with lithium-ion batteries there can be disadvantages in form of safetyissues. In an abuse situation a Li-ion cell can undergo a thermal runaway releasing excessive heat,flammable and toxic gas emissions and eventually accompanied by dissembling/explosion and fire. LÄS MER

  3. 3. Sustainable Aluminum and Iron Production

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Reza Beheshti; Emma Strömberg; Jafar Safarian; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability; Optimization; Black Dross; Salt removal; Steel flux agent; Waste processing; Greenhouse gases; Direct reduction; COMSOL Multiphysics®; Kemi; Chemistry;

    Sammanfattning : Aluminium recycling requires 95% less energy than primary production with no loss of quality. The Black Dross (BD) produced during secondary aluminium production contains high amounts of water-soluble compounds, therefore it is considered as a toxic waste. LÄS MER

  4. 4. Electrical Properties of Nanocrystalline WO3 for Gas Sensing Applications

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Anders Hoel; Peter Heszler; Claes-Göran Granqvist; Lars Österlund; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Nanoparticle; Gas sensors; Tungsten trioxide; Teknisk fysik; TECHNOLOGY Engineering physics; TEKNIKVETENSKAP Teknisk fysik;

    Sammanfattning : Tungsten trioxide is a material with a variety of application areas. For example, the material is used within thin film technologies as electrochromic material in smart windows, as electrochemically functional material in thermal control applications or as active layer in gas sensing application.

  5. 5. Evaluation of process parameters and treatments of different raw materials for biogas production

    Detta är en avhandling från Lund University

    Författare :Malik Badshah; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; biogas; lignocellulosics; inoculum to substrate ratio; feed composition; toxicity; furaldehydes; paper and pulp sludges.;

    Sammanfattning : The anaerobic digestion process results in the production of biogas from a large diversity of organic residues, which can be used as an alternate source of energy generation and for waste management. However, the biogas production technology is not exploited efficiently due to the characteristics of raw materials, poor methane yields, process instability, limited raw materials and lack of knowledge about the process.
