  2. 1. Water Curtains in Gas Storage. An Experimental Study

    Author : Carl-Olof Söder; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; analytical simulations; unlined gas storage; jointed rock; gas migration; gas containment; geo-hydrological test methods; hydromechanical breakdown;

    Abstract : Water curtains have been used for more than 20 years to prevent the escape of gas from caverns excavated in rock. Today, the use of water curtains appears to be increasing, with applications in various forms of storage caverns. READ MORE

  4. 2. Determining the quality of natural gas and biomethane : Development of a correlative method and instrument prototype for measuring gas quality

    Author : Taras Koturbash; Vladimir G. Kutcherov; Andrew R. Martin; Khaled Loubar; KTH; []
    Keywords : Natural gas; biomethane; calorific value; Wobbe Index; ultrasonic measurement; sound attenuation; Energy Technology; Energiteknik;

    Abstract : The composition of natural gas highly depends on its origin: natural gas from various deposits, substitute natural gas that can be produced from fossil fuels or renewable sources. The intermixing of gases from various supply sources during pipeline transportation also leads to more complicated and unpredictable gas composition variations at the consumption site. READ MORE

  5. 3. Pathways to deep decarbonisation of carbon-intensive industry in the European Union - Techno-economic assessments of key technologies and measures

    Author : Johan Rootzén; Chalmers tekniska högskola; []

    Abstract : By Year 2050, the EU has committed itself to reducing greenhouse gas emissions by 80%–95%relative to the levels in 1990, so as to contribute to global efforts to limit the long-term globalaverage temperature increase to.... READ MORE

  6. 4. Nitrous Oxide Emission from Circulating Fluidized Bed Combustion

    Author : Lars-Erik Åmand; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air supply dependence; fluidized beds; homogeneous heterogeneous reactions; fluidized-bed boilers; bed temperature dependence; N2O emissions; circulating fluidized-bed boilers; gas-concentration profiles;

    Abstract : In the present thesis N2O results are presented from several measurement projects on two commercial circulating fluidized bed (CFB) boilers. Traditional parameter studies have been carried out, as well as test programs where various nitrogen-containing species were injected into the furnace or gas-concentration profiles in the combustion chamber were measured.
