“…The average absolute relative deviation (AARD%) for the density calculations using the equation (1) compared with different investigators were represented in table 6 [10,[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. The average absolute relative deviation was 0.05% for 99 data points, which is a satisfactory result.…”

Viscosity and density are thermophysical properties crucial to characterizing any kind of fluid such as aqueous amines. These blends are becoming more and more relevant for their CO 2 capture potential, such that having accurate viscosity and density measurements would prove useful. Densities and viscosities of these mixtures at atmospheric pressure may be found in the literature although it is more difficult to find values at high pressures, these potentially proving interesting when seeking to provide a full description of these fluids. Viscosity and density measurements at high pressures (up to 120 MPa) and at temperatures between 293.15 and 353.15 K of MDEA + water and MEA + water mixtures (both from 10 % to 40 % amine mass fraction) are presented in this work. Density measurements were performed with an Anton Paar DMA HPM densimeter with an expanded uncertainty (k = 2) less than ± 0.7 kg•m-3. A falling body technique was used to measure viscosities at high pressures due to its sturdiness in terms of corrosion. Details of this latter equipment are presented, including calibration using n-dodecane and uncertainty calculations, which give a relative expanded uncertainty (k = 2) of less than ± 2.4 % for the highest viscosity and ± 2.9 % for the lowest.

“…Average absolute deviations for DEA-water mixtures are 0.09% from [12], 0.10% from [13], 0.07% from [14], 0.06% from [15], 0.7% from [16] (the disagreement occurs at 80°C) and 0.29% from [17]. As regards TEA-water mixtures, average absolute deviation is 0.09% from [14] and 0.15% from [18]. Finally for DMEA-water mixtures, it is 0.05% from [1917], 0.07% Viscosity of the studied mixtures decreases when temperature is increased or pressure is decreased and these effects are similar for all amines.…”

In this paper, density and viscosity measurements at pressures up to 140 MPa are presented in a temperature range from (293.15 to 393.15) K for diethanolamine (DEA) + water, triethanolamine (TEA) + water and 2-dimethylaminoethanol (DMAE) + water in amine weight concentrations from 10% to 40%. Densities were measured using a vibrating tube densimeter (Anton Paar DMA HPM) with an expanded uncertainty (k = 2) less than ± 0.7 kg•m-3. Viscosity measurements were obtained using a falling body viscometer which was calibrated with water and dodecane. The viscosity expanded uncertainty (k = 2) ranges from ± 2.5% for the highest viscosity to ± 3.2% for the lowest.
