    Absorption of CO2 in aqueous blend of methyldiethanolamine and arginine حسب Talkhan, Ahmed Gomaa

    منشور في 2020
    "…However, for CO2 partial pressure of above 20 kPa, the addition of Arg caused a decrease in the solubility of CO2. The obtained loading data were correlated using a semiempirical (SE) vapour liquid equilibrium (VLE) model with an average absolute deviation (AAD) less than 4.1% between the predicted and the experimental values. …"
