CO2 Capture, Transport and Storage processes: Thermodynamic Investigation of Relevant Fluid Mixtures

Carbon capture and storage (CCS) technology could become a reliable solution for reducing CO2 atmospheric emissions in order to hinder global warming. In this direction, the European Union aims to reduce emissions to 40% below 1990 levels by 2030, while individual countries are called to adopt binding legislation. In this study, the thermodynamic properties of CO2 mixtures with both traditional CCS solvents (such as glycols or alkanolamines) and novel tailor made solvents (such as ionic liquids and deep eutectic solvents) will be experimentally investigated. In a second step, various thermodynamic theories, such as the NRHB, PC-SAFT and CPA equations of state, will be extended / evaluated in modeling thermodynamic properties of CO2 mixtures relevant to CCS. The accurate prediction of thermodynamic properties will serve towards the further development of novel capture processes and the rational design of any process in a pilot plant or higher industrial scale.
