  1. 11. Steam Prediction at an Integrated Pulp and Paper Mill : Mondi Dynäs in Kramfors Municipality

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Energivetenskap

    Författare :Jimmy Sehlberg; [2020]
    Nyckelord :Steam prediction; Prediction; Industrial prediction; ångprediktion;

    Sammanfattning : The most important energy carrier at an integrated pulp and paper mill is steam, it is essential to power components and machinery. The components create variations in the steam grid network, variations that exceed the capacity of the steam accumulator. LÄS MER

  3. 12. Pulse Electric Field as a Pre-treatment Method of Wastewater Sludge prior to Anaerobic Digestion

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Milton Matilde; [2020]
    Nyckelord :PEF; AD; biogas yield; sludge pre-treatment; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Sammanfattning : This work analyzed the impact caused by different intensities of Pulsed Electric Fields (PEF) pre-treatment on the biogas production from small-scale anaerobic digesters of wastewater sludge under thermophilic conditions. PEF technology consists of passing the substrate through an electric field which generates a potential difference across the cells, resulting in electroporation. LÄS MER

  4. 13. The feasibility of producing and utilizing bioenergy in Linga Linga, Mozambique : Potential resources, conversion techniques and applications

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Mila Ebrahim; Fanny Lilja; [2019]
    Nyckelord :anaerobic digestion; biochar; biomass; bioenergy; biomass combustion; charcoal; gasifier cookstove; sustainable bioenergy;

    Sammanfattning : The aim of the project was to investigate the possibility of producing and utilizing bioenergy from available local resources in the village Linga Linga, Mozambique. Suitable conversion techniques for producing and utilizing bioenergy were identified through a literature study. LÄS MER

  5. 14. Towards a prototype of a modular biogas system

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Arvid Emilsson; Andreas Buhrgard; [2019]
    Nyckelord :Biogas; Vehicle gas; CHP; micro-CHP; farm-based; energy audit; techno-economic analysis; energy evaluation; upgrading; water-scrubber; small-scale; scalable; stand-alone; mass-production;

    Sammanfattning : As of today, large unused potential for biogas production exist within the Swedish agriculture sector. The biogas production within this sector is, however, associated with several problems such as poor energy efficiency and non-profitable systems. This is to some degree due to lack of standardized technical solutions. LÄS MER

  7. 15. Opportunities for small-scale anaerobic digesters for hotels and restaurants in Kathmandu, Nepal

    Master-uppsats, KTH/Energiteknik

    Författare :Avinash Dhital; [2018]
    Nyckelord :anaerobic digestion; biogas; bio-waste; small-scale; cooking; fuel; hotels; restaurants; Nepal;

    Sammanfattning : About 83% of total energy consumed in Nepal comes directly from the solid fuels. The import of Liquified Petroleum Gas (LPG) is also growing at an exponential rate. LÄS MER
