Physical properties of PZ solution used as a solvent for CO2 removal

- Density and viscosity and CO2 diffusivity of CO2 loaded amine solutions are studied.
- A reliable description of physical properties is fundamental for a correct modeling.
- New correlations which take into account the influence of CO2 are proposed.
- An expression for diffusivity of CO2 in the PZ solvent is proposed.
- The proposed expression allows a reliable representation of experimental data.
