  3. 2. On the use of process integration methods : evaluation of energy and CO2 emission strategies in blast furnace ironmaking and oxygen steelmaking

    Författare :Christer Ryman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : This work deals with sustainable resource utilisation in integrated (iron ore based) steelmaking, with special emphasis on how to analyse process adaptation and developments aiming towards lowering of the emission of greenhouse gases, in particular carbon dioxide (CO2), to the atmosphere. Climate change and management of CO2 are real issues for the steel industry these days. LÄS MER

  4. 3. Engineered Wetlands and Reactive Bed Filters for Treatment of Landfill Leachate

    Författare :Agnieszka Kietliñska; KTH; []
    Nyckelord :Blast furnace slag; Compact constructed wetland; Metals; Nitrogen; Polonite; Sorbents;

    Sammanfattning : The main objectives of this study were to investigate (i) anovel wetland treatment technology and (ii) selected bed filtermedia for the removal of contaminants from landfill leachate. Areview of the literature concerning experiences of the use ofconstructed wetlands (CW) for the removal of nitrogen fromlandfill leachate, showed that at least three groups oftreatment systems are in practice: sub-surface flow wetlands,hybrid systems (a combination of vertical and horizontal flowwetlands) and, compact constructed wetland (CCW).

  5. 4. Chloride transport and chloride threshold values : studies on concretes and mortars with Portland cement and limestone blended cement

    Författare :Dimitrios Boubitsas; RISE; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement; Mortar; Concrete; Corrosion; Reinforcement; Chloride ions;

    Sammanfattning : Reinforced concrete is one of the most widely used building materials and if it is properly designed and produced, it is an extremely durable material with a service life up to 100 years. However, under certain environmental conditions the service life of reinforced concrete structures is more limited. LÄS MER
