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

    University essay from KTH/Kemiteknik

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

    Abstract : 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.

  3. 2. Review and Design Adaptations of a SrCl2-NH3 bench-scale Thermochemical Heat Storage system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Hjörtur Brynjarsson; [2021]
    Keywords : Thermochemical heat storage TCS ; SrCl2-NH3; system design; kinetics; absorption; desorption; octaammine; diammine; monoammine; pressure management; commissioning; Termokemisk värmelagring TCS ; SrCl2-NH3; systemdesign; kinetik; absorption; desorption; oktaammin; diammin; monoammin; tryckhantering; driftsättning;

    Abstract : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. READ MORE

  4. 3. Stripper Modification of a Standard MEA Process for Heat Integration with a Pulp Mill

    University essay from KTH/Kemiteknik

    Author : Paty Arango Munoz; [2020]
    Keywords : Carbon dioxide capture; pulp mill; chemical absorption; modelling; heat integration; Koldioxidinfångning; massabruk; kemisk absorption; modellering; värmeintegration;

    Abstract : De 20 största massabruken i Sverige släpper tillsammans ut ungefär 20 miljoner ton CO2 per år. Dessa utsläpp har biogent ursprung och anses därför vara klimatneutrala. Massa- och pappersindustrin är därmed en lämplig kandidat för implementeringen av BECCS (eng. READ MORE

  5. 4. A Numerical Calculation Tool Design for the Performance Assessment of a Bench-Scale Thermochemical Heat Storage System

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : DIYUE WANG; [2020]
    Keywords : Calculation tool; SrCl2-NH3; Performance evaluation; Mass; Energy; Beräkningsverktyg; SrCl2-NH3; Prestandasutvärdering; massa; energi;

    Abstract : Thermochemical heat storage (TCS) is a technology to convert the heat and cold energy into chemical energy, via reversible chemical reactions, to be stored for heating and cooling applications. TCS technology is gaining interest for its very compact energy storage densities offering attractive thermal energy storage (TES) alternatives to decrease energy-related greenhouse gas(GHG) emissions and contribute to sustainable development.

  6. 5. 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
