| Abstract | In order to mitigate climate change, and especially to reduce the carbon dioxide emissions from large industrial CO2 emitters, the development of new Carbon Capture and Storage or Utilization (CCS/U) technologies and the improvement of current processes is a necessity in order to reduce the implementation costs of such environmental solutions. Focusing on the most advanced technology, namely the post-combustion CO2 capture using absorptionregeneration process with amine(s) based solvent, the solvents currently used (e.g. monoethanolamine (MEA), activated solutions of methyldiethanolamine (MDEA) or 2-amino-2-methyl-1-propanol (AMP) with piperazine (PZ)) still involve a too high energy consumption in the regeneration step. An alternative to conventional solvents is the use of biphasic solvents. Indeed, for given temperature and/or CO2 loading conditions, such solvents exhibit a liquid-liquid phase separation into CO2-rich and CO2-lean phases. As illustrated on Fig.1., this phenomenon allows an important energy saving by regenerating only the heavy CO2-rich phase after a separation in a decanter unit. |
