Density and Viscosity of Partially Carbonated Aqueous Tertiary Alkanolamine Solutions at Temperatures between (298.15 and 353.15) K

Abstract

The density and viscosity of partially carbonated aqueous solutions of either 2-dimethylaminoethanol or 2-diethylaminoethanol were measured over a temperature range of (298.15 to 353.15) K with alkanolamine mass fractions of 0.15 to 0.45. Correlations were developed to represent the density and viscosity of these solutions as a function of amine concentration, CO2 loading, and temperature. For the density, the correlation represents the experimental data to within ± 0.2 %, while the viscosity data were correlated to within ± 4 %. The data and models reported in this paper will help facilitate a better understanding of the performance of these amines in CO2 capture processes, especially in relation to mass transfer and hydrodynamic calculations.

Physical Properties of MEA + Water + CO2 Mixtures in Postcombustion CO2 Capture: A Review of Correlations and Experimental Studies

“…Correlations were able to represent literature data with less than 1% AARD. Weiland's correlation showed a higher deviation for data presented by Amundsen et al [2] and Zhang et al [29] compared to Hartono et al [1] and Han et al [4]. Hartono's correlation showed a good agreement with data given by Zhang et al [29].…”

“…Weiland's correlation showed a higher deviation for data presented by Amundsen et al [2] and Zhang et al [29] compared to Hartono et al [1] and Han et al [4]. Hartono's correlation showed a good agreement with data given by Zhang et al [29]. e maximum deviation is beyond the expanded combined uncertainties reported in data sources, and calculated AARD shows that the agreement between correlated and experimental densities is satisfactory.…”

“…is could be due to the uncertainties related to the experiments. Hartono's correlation showed a highest AARD of 3.80% for work done by Amundsen et al [2] and a maximum deviation of 0.195 MPa·s at the CO 2 loading of 0.38 mol CO 2 /mol MEA and T � 303.15 K for data presented by Zhang et al [29]. Table 16 lists the relevant correlations for the surface tension.…”

Measuring the density and viscosity of H 2 S-loaded aqueous methyldiethanolamine solution

“…Jayarathna et al [7,8], measured the density and surface tension of CO 2 [11,12,13,14,15,16,17,18]. All reported data show that density, viscosity and surface tension measurements of carbonated aqueous alkanolamine solutions increase with increasing CO 2 loading and decrease with temperature.…”

Artificial Neural Networks (ANNs) for Density and Viscosity Predictions of CO2 Loaded Alkanolamine + H2O Mixtures

“…Weiland et al [6] and Hartono et al [11] proposed correlations for density and viscosity of CO 2 -loaded aqueous MEA mixtures. Zhang et al [15] discussed the density and viscosity of CO 2 -loaded aqueous 2-dimethylaminoethanol (DMAE) and 2-diethylaminoethanol (DEAE) solutions.…”
