  1. 1. Simulation of stripper modifications for bioenergy carbon capture by absorption

    Master-uppsats, KTH/Kemiteknik

    Författare :Laia Villar I Comajoan; [2021]
    Nyckelord :BECCS; Carbon capture; Post-combustion absorption; Potassium carbonate; Energy Penalty; BECCS; Koldioxid infångning; Absorption efter förbränning; Kaliumkarbonat; Energistraff;

    Sammanfattning : Att koldioxidutsläppen neutraliseras är avgörande för att begränsa klimatförändringarna. Bioenergi i kombination med separation och lagring av koldioxid (BECCS) är en Teknik som kan generera negativa utsläpp. Det största hindret för dess storskaliga genomförande är de höga energikraven för processen.

    Nyckelord :Climate change; Extreme weather; Building energy efficiency; Passive houses;

    Sammanfattning : In September 2020, Northeast China suffered three unprecedented typhoons in half a month, and there was freezing rain in early November, all of which led to the large-scale urban power failure. The occurrence of these phenomena makes people directly see climate change and its impact on the living environment of human beings. LÄS MER

  3. 3. Phosphorus reduction in wastewater using microalgae with different phosphorus starvation periods

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Fredrika Murby; [2021]

    Sammanfattning : The global energy demand supplies mainly from fossil fuels, which is neither sustainable nor environmentally friendly and aims to global warming. Therefore, both more investments in renewable energy sources such as bioenergy are required, as well as new technologies such as carbon capture and storage (CCS) to handle the emissions from existing combined heat and power (CHP) plants.

    Sammanfattning : Paper 1 There is a trend towards intensification of forest use in many European countries, fuelled by an increased demand for forest products and services, driven by the global population, income growth and an increasing per capita consumption of forest products and forest ecosystem services, and politically promoted by a shift towards a bio-based economy. Based on the assumption that decisions on forest management relate to synergies—e. LÄS MER
