  5. 4. Thermodynamic Properties of CO2 Mixtures and Their Applications in Advanced Power Cycles with CO2 Capture Processes

    Författare :Hailong Li; Jinyue Yan; Umberto Desideri; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermodynamic property; vapour liquid equilibrium; density; equation of state; interaction parameter; CO2 mixtures; evaporative gas turbine; chemical absorption; oxy-fuel combustion; cost evaluation; CO2 capture and storage; Chemical engineering; Kemiteknik;

    Sammanfattning : The thermodynamic properties of CO2-mixtures are essential for the design and operation of CO2 Capture and Storage (CCS) systems. A better understanding of the thermodynamic properties of CO2 mixtures could provide a scientific basis to define a proper guideline of CO2 purity and impure components for the CCS processes according to technical, safety and environmental requirements.
