文摘
- •
Extended UNIQUAC framework is used to model the liquid-liquid phase change solvents (DEEA and MAPA) for CO2 capture.
- •
The studied systems are: H2O-DEEA-CO2, H2O-MAPA-CO2, and H2O-DEEA-MAPA-CO2.
- •
The developed model accurately represents all the equilibrium and thermal data with a single unique set of parameters.
- •
Liquid-liquid equilibrium (de-mixing) is reproduced satisfactorily by the model.
- •
Model calculated speciation for the studied systems are also presented.
