چکیده

Determination of physical properties and obtaining parameters related to thermodynamic models in the design and simulation of industrial units the absorption and disposal of amine solvents is essential. Mixing of different compounds often results in non-organic solutions. The deviation from the ideal state can be examined through a well-studied study. In this dissertation, the thermodynamic properties of binary mixtures were studied in order to understand and interpret the intermolecular interactions of the constituent parts of the mixture, as well as the testing of the efficiency of the thermodynamic models. Excess molar volume and deviation of ideal viscosity for 5 binary mixtures of AMP TETA, AMP TEPA, TETA H2O, TEPA H2O and AMP H2O. Experimental parameters related to NRTL, Wilson and expansion models Redeil-Kisters were calculated. Then, the density and gravity of two blended mixtures were measured from AMP TETA H2O and TEPA AMP H2O and predicted with the help of two-dimensional parameters. The NRTL model has a better accuracy in predicting the viscosity variation of the solvent mixture compared to the Wilson model. The excess molar volume was negative for all mixtures, which indicates a strong solvent-soluble bond to each component in pure form. The flux is a descendant function of temperature, due to the degradation of the inter-molecular structures due to the increase in temperature and the placement of small molecules in these structures. Viscosity variation for solvent mixtures in low dilution of amine has a negative deviation and, at high dilution, amine is a positive viscosity deviation. Finally, the density and gravity of the two three-component mixtures of AMP TETA H2O and AMP TEPA H2O each were measured and reported in three different molar ratios after CO2 loading.
