  1. 1. Impact of Implementing CCS Technology on a Biomass Power Plant

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Azin Mohebbi; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This study examines the implementation of carbon capture and storage (CCS) technology, specifically the monoethanolamine (MEA) chemical absorption method, in a biomass power plant. The aim is to assess the energy requirements and optimize the solvent processes to improve the overall efficiency of the carbon capture process. LÄS MER

  3. 2. Benchmarking a Cryogenic Code for the FREIA Helium Liquefier

    Kandidat-uppsats, Uppsala universitet/FREIA

    Författare :Elias Waagaard; [2020]
    Nyckelord :Cryogenics; Liquefaction; Helium;

    Sammanfattning : The thermodynamics inside the helium liquefier in the FREIA laboratory still contains many unknowns. The purpose of this project is to develop a theoretical model and implement it in MATLAB, with the help of the CoolProp library. LÄS MER

  4. 3. Simulation of a scaled down version of a run-around coil heat recovery system on COMSOL® Multiphysics.

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

    Författare :Abhimanyu Tyagi; [2019]
    Nyckelord :;

    Sammanfattning : Due to changing anthropological activities, the consumption of resources is continuously increasing. As humans are spending more time indoors, the energy demand is also increasing. The building sector is a major consumer of energy. In buildings, space heating is important to maintain a comfortable space. LÄS MER

  5. 4. Alternative methods to prevent thermal cracking in concrete

    M1-uppsats,

    Författare :Alexander Barchin; Navid Sedighi; [2019]
    Nyckelord :Massive concrete structures; heat development; cement hydration; temperature reduction; cracking; fly ash; ice; coarse aggregates; cooling methods; practical tests.; Massiva betongkonstruktioner; värmeutveckling; cementhydrataion; temperaturreducering; sprickbildning; flygaska; is; grov ballast; kylningsmetoder praktiska försök.;

    Sammanfattning : In the construction industry, concrete is the most common material, because of its good properties such as compressive strength and endurance. Concrete is a composition of several different materials where one of the main components is cement. When the hydration process starts, large amount of heat is generated. LÄS MER

  7. 5. Temperature reduction during concrete hydration in massive structures

    Master-uppsats, KTH/Betongbyggnad

    Författare :Sandra Lagundzija; Marie Thiam; [2017]
    Nyckelord :Massive concrete structures; hydration heat; temperature reduction; crack risk; mineral additions; concrete cooling; Massiva betongkonstruktioner; värmeutveckling; temperaturreducering; sprickbildning; mineraltillsatser; kylning av betong;

    Sammanfattning : Concrete is one of the most used building materials in the world because of its good properties. However, cement which is one of the main components in concrete, produces a high amount of heat during the hydration process. The generated heat leads to temperature rise inside the structure. LÄS MER
