  3. 3. Practical implementation of Bio-CCS in Uppsala : A techno-economic assessment

    University essay from KTH/Energiteknik

    Author : Robert Djurberg; [2020]
    Keywords : BECCS; Bio-CCS; CCS; techno-economic assessment; BECCS; Bio-CCS; CCS; teknoekonomisk analys;

    Abstract : To decrease global warming, bioenergy with carbon capture and storage (Bio-CCS) has been proposed as an effective and necessary tool. Combusting biomass and capturing carbon dioxide (CO2) from the same process results in net negative emissions, hence, reducing the concentration of CO2 in the atmosphere. READ MORE

  4. 4. Partial denitrification as nitrite provider for mainstream anammox

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Felix Wallin Holmin; [2020]
    Keywords : Water engineering; Environmental engineering; Mainstream anammox; Partial denitrification; PDA; MBBR; Nitrogen removal; Vattenförsörjningsteknik; Avloppsteknik; Technology and Engineering;

    Abstract : In traditional wastewater treatment, nitrogen is removed through the biological process combination of nitrification and denitrification. Although it is a well-established method, the need for aeration and possible addition of an external carbon source results in it being an energy-negative and costly process, thus making alternative methods for nitrogen removal compelling to examine.
