  1. 21. Systems Analysis of Chemicals Production via Integrated Entrained Flow Biomass Gasification : Quantification and improvement of techno-economic performance

    Författare :Jim Andersson; Eric D. Larson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Lignocellulosic biomass gasification is a promising production pathway for green chemicals, which can support the development towards a more sustainable society where fossil fuels are replaced. To be able to compete with fossil fuels, a highly efficient production of biomassbased products is required in order to maximize overall process economics and to minimizenegative environmental impact.

  3. 22. Feed efficiency in dairy cows: individual cow variability in component traits

    Författare :Abdulai Guinguina; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Feed efficiency (FE) varies between cows, and this variation is linked to the variation in energy metabolism variables. Respiration chambers are needed for measuring energy metabolism variables while individual cow dry matter intake (DMI) records are necessary for measuring FE, but these are difficult to obtain due to cost and logistic constraints.

  4. 23. Sustainable policy for energy, land and natural resources

    Författare :James MacGregor; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental economics; natural resources; energy; climate; microcredit; sustainability; cost-benefit analysis; poverty; agriculture;

    Sammanfattning : This thesis consists of four papers which are related to critical natural resource issues from a developing and emerging country perspective. All four papers demonstrate the importance of financial incentives in driving behaviour and investments. LÄS MER

  5. 24. Energy Efficient Evaporation in Future Kraft Pulp Mills

    Författare :Jessica Algehed; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; process integration; black liquor; pulp and paper; pinch technology; wastewater; evaporation; excess heat; economics; energy;

    Sammanfattning : In the future, the technical and economic conditions for energy savings in the pulp and paper industry will change. More excess heat will be available in future mills above 80°C than in existing mills, increasing the potential for process integration, and governmental actions for reducing CO2 emissions and the deregulation of electricity markets will change the economic conditions for investments aimed at saving energy.

  7. 25. Analysing strategic energy-related investments in process industries : applied studies at a pulp and board mill

    Författare :Magnus Karlsson; Lars J. Nilsson; Linköpings universitet; []
    Nyckelord :MIND; Industrial energy systems; Investment; pulp and paper; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The potential to reduce energy demand in industrial applications is often substantiaL Since energy cost represents a considerable share of the value added in several categories of process industries, a great potential exists for cutting costs through investment, for instance in energy efficiency improvements. However, industrial energy systems form complex relations not only within the industrial unit, but also in the interaction with their surroundings. LÄS MER
