  1. 21. Installation av solceller för KTH

    M1-uppsats, KTH/Produktionsutveckling

    Författare :Jad Edward Soumi; [2023]
    Nyckelord :Solar panels; KTH building; sustainable energy production; electricity production; cost; payback period.; Solpaneler; KTH-byggnaden; hållbar energiproduktion; elproduktion; kostnad; återbetalningstid.;

    Sammanfattning : Detta arbete fokuserar på användningen av solpaneler för att producera den energi som behövs för KTH-byggnaden i Södertälje och minska dess miljöpåverkan. Problembeskrivningen betonar vikten av att minska energiförbrukningen och använda förnybara energikällor för att täcka det kvarvarande energibehovet för byggnader som KTH i Södertälje. LÄS MER

  3. 22. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Christopher Hallén; Marcus Johansson Storne; [2023]
    Nyckelord :;

    Sammanfattning : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. LÄS MER

  4. 23. Surface treatment methods for metal components trays and frames

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Josu Najera Bernabeu; Alaitz Egaña Azkargorta; [2023]
    Nyckelord :;

    Sammanfattning : The proper selection of materials and surface treatment is critical in ensuring the strength, durability, and safety of metal structures in various environments. Therefore, this project is being developed in collaboration with Aurobay Company to explore and provide insights into the most suitable material and surface treatment method for a frame. LÄS MER

  5. 24. Evaluation of Excess Heat Driven Carbon Capture Integrated at a Swedish Pulp Mill

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Frida Nilsson; [2023]
    Nyckelord :CCS; BECCS; pulp and paper industry; pulp mill; excess heat; MEA; HPC; AMP; DMSO; chemical engineering; environmental engineering; Technology and Engineering;

    Sammanfattning : As the atmospheric carbon dioxide keeps increasing, bioenergy with carbon capture and storage (BECCS) is getting increased attention as a measure to reduce the emissions of carbon dioxide. It is especially interesting in Sweden where the extensive paper and pulp industry constitutes point sources of biogenic carbon dioxide. LÄS MER

  7. 25. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Anna Wagne; [2023]
    Nyckelord :Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

    Sammanfattning : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. LÄS MER
