https://doi.org/10.1021/acs.iecr.0c00940 “As discussed previously, the properties of hypothetical water-lean solvents can be calculated using parameters such as molar mass, density, and viscosity (for the Wilke–Chang

https://doi.org/10.1021/acs.iecr.0c00940 “Table 1 shows the relevant parameters for a number of aqueous and water-lean solvents. It is important to highlight that many of these parameters were not

https://doi.org/10.1021/acs.iecr.0c00940 ” As verified before, substitution of water by an organic diluent shifts the vapor–liquid equilibrium curve toward less CO2 absorption for a fixed CO2 partial pressure. (10,11,14) Much
