“…This emphasizes strong intermolecular attractions in the solution. As reported by Idris et al, (2018), < 0 for the water rich region indicates weak intermolecular attractions. The presence of strong intermolecular attractions is determined as > 0 for amine rich region.…”

“…The study is based on measured density and viscosity data of this and previous works performed in University of South-Eastern Norway (USN) (Idris and Eimer, 2016;Idris et al, 2018). Idris and Eimer, (2016) and Idris et al, (2018) discussed the density and viscosity of aqueous 3A1P solutions under the range of mass fractions 1 (i=1 and 2 refer amine and water respectively) within 0-1 and temperatures 293.15-353.15K and 298.15-373.15K respectively. The correlation suggested by Aronu et al, (2012) as given in (14) was adopted to correlate aqueous 3A1P density data.…”

“…Empirical correlations of such properties can provide the required data within a considered concentration and temperature range. Abundant resources are available for the density and viscosity of aqueous MEA (monoethanol amine) in the literature with suggested correlations, while reported studies are limited for 3A1P (3-Amino-1-propanol) (Idris and Eimer, 2016;Idris et al, 2018).…”

Density and viscosity data and relevant correlations are essentially needed to perform mathematical modelling and simulations for the design of process equipment. Correlations that are developed to cover a range of concentrations and temperatures help to use them in mathematical modelling and simulations of absorptiondesorption processes. In this study, a density correlation was proposed for 3A1P (3-Amino-1-propanol) + H2O mixtures. The McAllister three body model was adopted to correlate kinematic viscosity data of MEA (monoethanol amine) + H2O mixtures and kinematic viscosity data for 3A1P + H2O mixtures. The Eyring's viscosity model based on absolute rate theory was used to correlate dynamic viscosity data. A Redlich-Kister type polynomial was proposed to fit the excess free energy of activation for viscous flow for 3A1P + H2O mixtures. The developed correlations were able to represent density and viscosity data with accepted accuracy and can be used to perform engineering calculations.

“…In general, the time of reaching equilibrium was short at low pressures, however increasing CO 2 pressure resulted in a very long time of equilibration. This is attributed to the increasing viscosity [ 28 ] upon CO 2 absorption that causes higher resistance of diffusion and hindrance in migration of CO 2 molecules [ 29 , 30 ]. The observed increase of viscosity was very high.…”

Deep eutectic solvents (DESs) became an object of a great interest as an alternative to ionic liquids (ILs) and commonly used in CO2 capture amine solutions. In the present study, five different DESs based on 3-amino-1-propanol as physical-chemical CO2 absorbents were used. The composition was chosen in order to estimate the effects of hydrogen bond acceptor:hydrogen bond donor (HBA:HBD) molar ratio, anion type and length of alkyl chain of composing salt. The Fourier Transform Infrared (FTIR) spectroscopy was used to confirm chemical reaction. The solubility of CO2 was measured at low pressures up to 170 kPa at the temperature range of 293–318 K. Viscosity, polarity and Kamlet–Taft parameters were determined in order to estimate the dependences of the parameters and the CO2 capacity. CO2 uptake was observed to improve with decreasing molar ratio of hydrogen bond donor. Comparing the CO2 capacity of [TBAC]-based DESs, at the approximate pressure of 50 kPa, it was observed that the capacity increased in the following order of molar ratios—1:8 < 1:6 < 1:4 and a decrease in molar ratio from 1:8 to 1:4 resulted in about a 100% increase of capacity. Compared to [TBAC][AP] DESs, the [TEAC][AP] 1:4 and [TBAB][AP] 1:4 exhibited higher CO2 uptake, though the best results were obtained for [TBAB][AP].

“…According to Eyring's viscosity model, it can be argued that more energy is required to make necessary holes for molecules to jump in when they are closely packed. The sign of η E emphasizes strong specific interactions such as hydrogen bonding, which causes complex formations in the amine-rich region and weak interactions in the water-rich region [31].…”

Densities and viscosities of aqueous monoethanol amine (MEA) and CO2-loaded aqueous MEA are highly relevant in engineering calculations to perform process design and simulations. Density and viscosity of the aqueous MEA were measured in the temperature range of 293.15 K to 363.15 K with MEA mass fractions ranging from 0.3 to 1.0. Densities of the aqueous MEA were fitted for a density correlation. Eyring’s viscosity model based on absolute rate theory was adopted to determine the excess free energy of activation for viscous flow of aqueous MEA mixtures and was correlated by a Redlich–Kister polynomial. Densities and viscosities of CO2-loaded MEA solutions were measured in the temperature range of 293.15 K to 353.15 K with MEA mass fractions of 0.3, 0.4 and 0.5. The density correlation used to correlate aqueous MEA was modified to fit CO2-loaded density data. The free energy of activation for viscous flow for CO2-loaded aqueous MEA solutions was determined by Eyring’s viscosity model and a correlation was proposed to represent free energy of activation for viscous flow and viscosity. This can be used to evaluate quantitative and qualitative properties in the MEA + H2O + CO2 mixture.
