  2. 1. System studies of different CO2 mitigation options in the oil refining industry: Post-combustion CO2 capture and biomass gasification

    Author : Daniella Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; post-combustion CO2 capture. CO2 capture and storage CCS ; GHG emissions; oil refining industry; CO2 emissions; Fischer-Tropsch FT ; biomass gasification; energy market scenarios;

    Abstract : To reach the objective endorsed by the EU Council for reducing EU greenhouse gas (GHG) emissions by 80-90% compared to 1990 levels by 2050, extensive cuts are necessary in all sectors. The oil refining sector is a major energy user and thus a major GHG emitter. READ MORE

  4. 2. Opportunities for CO2 Reductions and CO2-Lean Energy Systems in Pulp and Paper Mills

    Author : Kenneth Möllersten; KTH; []
    Keywords : CO2 reduction; pulp and paper industry; energy system; biomass; CO2 capture and sequestration; black liquor; gasification; power production; outsourcing; sustainable energy management;

    Abstract : The risk for climate change is a growing concern for theglobal society. According to what is known as the Kyoto Protocol,developed countries have committed themselves to reduce theirgreenhouse gas (GHG) emissions. The purpose of this thesis hasbeen to analyse opportunities for CO2 reductions in Swedish pulpand paper mills. READ MORE

  5. 3. Reducing Diesel Engine Emissions - An Experimental Investigation

    Author : Arjan Helmantel; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical methods; Soot; Diesel; Emissions; HCCI;

    Abstract : In the recent past, the Diesel engine has been improved considerably in the areas ofperformance, fuel efficiency and exhaust emissions. In Europe, these improvements haveresulted in a strong increase in the sales of passenger cars equipped with a Diesel engine. READ MORE

  6. 4. Pathways for the European electricity supply system to 2050 – Implications of stringent CO2 reductions

    Author : Mikael Odenberger; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; abatement; Electrcity supply system; CO2;

    Abstract : This thesis, which consists of four separate papers, investigates possible pathways forthe European electricity supply systems to meet stringent CO2 emission reductions.Assessments are made for single EU member states, selected regions and the EU as awhole. READ MORE

  7. 5. Energy Export Opportunities from Kraft Pulp and Paper Mills and Resulting Reductions in Global CO2 Emissions

    Author : Erik Marcus Kristian Axelsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy export; Heat integration; Energy savings; Kraft pulp and paper mill; Global CO2 emissions;

    Abstract : With increasing energy prices and increasing demand for CO2-lean energy sources, energy savings in the pulp and paper industry become ever more relevant. Significant energy savings in kraft mills can be made by e.g. improved heat integration and installation of an energy-efficient evaporation plant. READ MORE
