  1. 26. Framework For Structuring Information For Environmental Management Of Industrial Systems

    Författare :Raul Carlson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Life cycle assessment LCA ; data format; characterisation; weighting; information structuring; Design for Environment DfE ; indicator; sustainable development; industrial environmental information systems; database;

    Sammanfattning : This thesis addresses information structuring for reducing cost, facilitate understandability, increase relevance and improve quality of environmental information. The research is based in experience, practical results and syntheses from three different but related research and development projects conducted between 1994 and 2004. LÄS MER

  3. 27. Targeted and untargeted analysis of organic contaminants from on-site sewage treatment facilities : Removal, fate and environmental impact

    Författare :Kristin Blum; Peter Haglund; Patrik Andersson; Pim Leonards; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; decentralized sewage treatment; wastewater; surface water; environmental fate; bioavailability; removal efficiency; mass fluxes; biochar; environment; GC×GC-MS; LC-IM-MS; mass spectrometry; contaminants; pollutants; prioritization; non-target analysis; screening; analytisk kemi; Analytical Chemistry;

    Sammanfattning : On-site sewage treatment facilities (OSSFs) are widely used all over the world to treat wastewater when large-scale sewage treatment plants (STPs) are not economically feasible. Although there is great awareness that the release of untreated wastewater into the environment can lead to water-related diseases and eutrophication, little is known about organic contaminants and their removal by OSSFs, environmental load and fate.

  4. 28. Selective Catalytic Reduction of NOx over Alumina-Supported Silver and Indium During Lean Operation

    Författare :Linda Ström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Catalytic emission control for vehicles was first applied in the 1970’s. The first such catalysts were designed to oxidize unburned hydrocarbons (HC) and carbon monoxide (CO). LÄS MER

  5. 29. Oxygen carrier aided combustion: Implementation of oxygen carriers to existing industrial settings

    Författare :Angelica Gyllén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ilmenite; Oxygen carrier aided combustion; Fluidized-bed; Biomass;

    Sammanfattning : Utilization of biomass and waste to produce heat and power is necessary for a sustainable future energy mix. Thermal conversion of biomass is considered to yield CO2 neutral emissions and the utilization of waste reduces its volumes in a world struggling to dispose of ever-increasing amounts. LÄS MER

  7. 30. Detecting, Modelling and Measuring Disturbances in Fixed-bed Combustion

    Författare :Sven Hermansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD modelling; solid fuels; grate furnaces; moisture content; fixed bed; combustion;

    Sammanfattning : Combustion of fixed fuel beds in grate furnaces is one of the most common techniques within production of heat and power from solid fuels. The grate furnace used to be a working horse for combustion of hard coal, while today the incitement of using renewable fuel sources has turned biomass and municipal waste into dominating fuel types.
