  1. 1. Förbättrad svavelavskiljning i våt gasrening vid Högdalenverket

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Marion Salem; [2023]
    Nyckelord :Sulphur oxides; Combined heat; and power plant; flue gas desulfurization; wet desulfurization; Svaveloxider; rökgasavsvavling; våta gasreningssystem;

    Sammanfattning : Vid Högdalens kraftvärmeverk produceras fjärrvärme och el, genom förbränning av hushålls och industriavfall. De negativa hälso- och miljökonsekvenserna som rökgasens föroreningar bidragit till, har lett till större intresse om teknikutveckling för rening av rökgasen ifrån miljögifter innan utsläpp till luft.

  3. 2. Techno-economic fesibility of a hybrid CSP (sCO2) - PV plant for hydrogen production

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

    Författare :Patricia Perez De La Calle; [2023]
    Nyckelord :Soec oxide electrolyzer cell SOEC ; Concentrated solar plant CSP ; Super critical cO2 sCO2 ; photovoltaic field PV ; Thermal storage TES ; electrolyzer; MoSES; high temperature electrolysis THE .;

    Sammanfattning : The global need to eliminate CO2 emissions and its consequent reduction in the use of fossil fuels drives the ongoing energy transition that highly involves the research achievements of the scientific community to reach the goals of this purpose. Renewable sources like photovoltaic and wind energy, are central to this endeavor, however, the intermittency of natural resources makes it non-dispatchable and energy storage is fundamental.

  4. 3. Comparing different methods of measuring particle size for pharmaceutical excipients

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Jiawen Wang; [2022]
    Nyckelord :particle size; comparison; Malvern analysis; Qicpic analysis; Pharmaceutical technology; Technology and Engineering;

    Sammanfattning : In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by laser diffraction analysis (Malvern wet and dry), dynamic image analysis (Qicpic), and microscopic methods (Qicpic, SEM, and light microscopy) to determine the applicability and limitations of each method, as well as to clarify their advantages and disadvantages.

  5. 4. Size detection limits of spICP-MS for analysis of nanoparticles in environmental media

    Kandidat-uppsats, SLU/Dept. of Soil and Environment

    Författare :Eline Goossens; [2018]
    Nyckelord :nanoparticle; detection limit; single particle ICP-MS; environmental analysis;

    Sammanfattning : Nanoparticles (NP) are widely integrated in our everyday lives, such as consumer products, health, agriculture, food, etc. This has resulted in a growing concern for their possible harmful effect on human health and the environment and the demand for characterization. LÄS MER

  7. 5. Measuring volatile nicotine from electronic cigarettes

    Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi

    Författare :Simon Lundegard; [2017]
    Nyckelord :AMS; denuder; e-juice; electronic cigarettes; NGI; nicotine; SMPS; Technology and Engineering; Chemistry;

    Sammanfattning : This thesis is focused on electronic cigarettes and the formulations (also known as e-juices) associated with these. The reason is that there have been countless studies on the health effects and nicotine delivery of normal cigarettes, but not as much on electronic cigarettes. LÄS MER
