    Abstract : Medan världen undergår en klimatkris, nya sätt för att mildra den har undersökts till det korta och långa loppet. Koldioxid är ett ämne som uppmärksammats då stora mängder av den släpps ut till atmosfären på grund av förbränningsprocesser. READ MORE

  3. 2. Carbon capture in biomass combustion plants using promoted potassium carbonate solutions : A cost and safety evaluation

    University essay from Mittuniversitetet/Institutionen för kemiteknik

    Author : Håkan Bergman; [2022]
    Keywords : BECCS; carbon dioxide; potassium carbonate; bioenergy carbon capture and storage; promoter; BECSS; Koldioxidinfångning;

    Abstract : Biomass combustion can be seen as CO2 neutral, thereby biomass combustion plants can have negative CO2 emissions if retrofitted with post combustion capture (PCC) technology using liquid absorbents. Monoethanolamine (MEA) has been used for carbon capture in coal combustion plants but are not suitable for use in biomass combustion plants due to corrosion and high solvent regeneration cost.

    Keywords : Noice pollution; vibrations; metro; nya tunnelbana project; noice absorbents; Buller; vibrationer; stomljud; luftburet ljud; nya tunnelbana projekt; absorbenter;

    Abstract : To meet the needs of the growing city of Stockholm, a large-scale project to expand the subway has been initiated. The tunneling involved in the project causes several disturbances, in terms of vibration and noise pollution, on the surroundings. This is problematic as vibration and noise pollution has been shown to have a negative health impact. READ MORE

    Abstract : As Covid-19 spread throughout the world in the early months of 2020 many people’s lives changed drastically. The situation forced millions of workers and students to start performing their work remotely from home. Currently in Sweden statistics shows that every third person working does it from home at least once a week. READ MORE

  6. 5. Attenuation of fan noise with passive methods : An experimental study in the implementation of a ducted fan inside the body of a blended wing body UAV

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Mustafa Kulbay; [2021]
    Keywords : ;

    Abstract : This report is about a novel approach to attenuation of fan noise in aerial vehicles, by way of implementing a ducted fan in the chassis of a four meter blended wing body plane. Three different one meter PVC pipes were used and their performances as silencers were tested by measuring the sound power level and calculating the insulation loss compared to a fan by itself.
