  2. 1. Industrial Symbiosis in the Swedish Forest Industry

    Author : Anna Wolf; Mats Söderström; Magnus Karlsson; René van Berkel; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest industry; integration; industrial symbiosis; evaluation; human dimensions; MIND method; skogsindustri; integration; industriell symbios; utvärdering; implementering; MIND-metoden; Environmental engineering; Miljöteknik;

    Abstract : Forskningen som presenteras i denna avhandling anknyter till forskningsfältet Industriell Ekologi och då särskilt den gren som kallas Industriell Symbios (IS). Inom IS förordas att ett företag kan öka produktionen och samtidigt minska resursanvändningen genom att effektivt integrera energi och materialflöden i ett större system. READ MORE

  4. 2. Bio-SNG from Thermal Gasification - Process Synthesis, Integration and Performance

    Author : Stefan Heyne; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; process modelling; performance indicators; biomass; energy systems; synthetic natural gas; gasification;

    Abstract : Biomethane or synthetic natural gas (Bio-SNG) produced from gasified renewable woody biomass is a promising option for replacing fossil natural gas. The complete interchangeability with natural gas in all its conventional applications such as in the power generation, transportation and chemical industry sector is of particular interest.

  5. 3. Techno-economic evaluation of integrated lignocellulosic ethanol production

    Author : Elisabeth Joelsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distillers dried grain with solubles; biorefinery; modelling; Aspen Plus; biogas; logging residues; spruce; wheat straw; wheat grain; heat; integration; pinch analysis; techno-economic evaluation; first generation; second generation; Ethanol; Lignocellulosic material;

    Abstract : Sweden has claimed that it wants to have a fossil-free vehicle fleet in 2030 as a milestone of its ambitious goal for 2050 to be a country with a sustainable and resource-efficient energy supply without any net GHG emissions. Production of bioethanol from plant materials is one potential method of meeting this goal. READ MORE

  6. 4. Biomass Gasification-Based Biorefineries in Pulp and Paper Mills – Greenhouse Gas Emission Implications and Economic Performance

    Author : Johan Isaksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; heat integration; energy efficiency; CO2 emissions; process integration; pulp and paper mill; biomass gasification;

    Abstract : The pulp and paper industry has a great opportunity to take advantage of the experience about forestry and wood handling for production of renewable fuels, chemicals and materials. Residues from forestry, i.e., tops, branches and stubs, have great potential to become a raw material that can replace crude oil or natural gas in many applications. READ MORE

  7. 5. Simulations of Evaporation Plants in Kraft Pulp Mills: Including Lignin Extraction and Use of Excess Heat

    Author : Marcus Olsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kraft pulp mill.; lignin extraction; heat integration; process integration; energy saving; excess heat; simulation; Energy-efficient evaporation; modelling;

    Abstract : In this thesis, evaporation plants at kraft pulp mills are simulated with the purpose of making them more energy efficient. The work is important since energy saving is assumed to be one of the major solutions for handling the world's energy demand in the future. READ MORE
