  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.

  2. 2. IMPLEMENTATION OF OXYFUEL COMBUSTION IN A WASTE INCINERATION CHP PLANT : A Techno-Economic Assessment

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Mostafa Saleh; Anton Hedén Sandberg; [2021]
    Nyckelord :CCS; Oxyfuel Combustion; Carbon Capture; Gas Separation Techniques; Waste Combustion; Cost Assessment of CCS; ASU; CPU; Wet-FGR; Dry-FGR;

    Sammanfattning : Global energy demand is predicted to rise in the coming decades, necessitating a shift to renewable energy sources to mitigate greenhouse gas emissions. However, due to the inability to supply renewable energy around the clock, it is estimated that only by adding an important technology, carbon capture and storage (CCS), it could be possible to reduce 80% of the 1990s greenhouse gas emissions.

  3. 3. Development of Sensor Concept to Regulate Fuel Supply During Priming of Water to Air Heater in Production

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Karl Hemlin; [2021]
    Nyckelord :;

    Sammanfattning : The Water To Air heater (WTA) is a component that heats the interior and the engine of the truck by heating coolant through a combustion of diesel fuel. It is vital that the Water To Air heater is primed with fuel prior to using it in order for it to start when desired. LÄS MER

  4. 4. LES modelling of spray combustion

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Arvid Åkerblom; [2021]
    Nyckelord :Gas Turbine; CFD; Large Eddy Simulation; Lagrangian Particle Tracking; Chemical Kinetics; Reaction Mechanism; Combustion; OpenFOAM; CHEMKIN; Technology and Engineering;

    Sammanfattning : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.

  5. 5. Design of a Polygeneration system in Filipinas ETCR, Colombia

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

    Författare :Germán Ropero Pérez; [2021]
    Nyckelord :;

    Sammanfattning : This project has addressed the design of a cost-effective Polygeneration system that guarantees a continuous, equitable and environmentally friendly energy supply for the rural settlement of Filipinas ETCR, (in Spanish, Espacios Territoriales de Capacitación y Reincorporación) Colombia, which is currently not achieved, due to a system that relies on the national electricity grid (with numerous outages) and on LPG (Liquefied Petroleum Gas) and wood to meet the thermal demand, mainly for cooking. For this purpose, in addition to the current energy supply situation, the energy demand according to type (electricity and heat) and sector (residential, commercial and agro-livestock) is characterized.
