ABSTRACT: This paper reports new viscosity data for unloaded and CO2-loaded aqueous 3-amino-1-propanol (3A1P) solutions. For the unloaded system, experiments were performed over the whole concentration range at temperatures between 298.15 and 373.15 K. In the case of a CO2-loaded system, measurements were performed at five different CO2-loadings ranging from 0.13 to 0.54 mol of CO2/mol of 3A1P at 0.30 and 0.50 3A1P mass fractions. The experimental data were also regressed using available methods from the literature.

1. INTRODUCTION Chemical absorption using an aqueous solution of alkanolamines is regarded as the matured available technology for the removal of carbon dioxide (CO2) from industrial gas streams.1,2 Among commercially available alkanolamines, monoethanolamine (MEA, IUPAC name: 2-aminoethanol) has been studied and utilized extensively due to its advantages such as fast chemical kinetics and high absorption rates. However, reaction of aqueous MEA with CO2 produces chemically stable carbamate that requires a high temperature to regenerate. This increases the energy requirement for such a process. Over the years, a number of other amines have been suggested as potential candidates for CO2-capture.3,4 The amine of interest in this study, 3-amino-1-propanol (3A1P), is a primary alkanolamine, and its schematic structure is shown in Figure 1. It is in the same class as MEA with the main difference being

The studied 3A1P solvent also showed a stable capture capacity after a number of cycles of absorption and regeneration processes, albeit loss of capture capacity was observed initially. Before this amine can be used industrially, information on chemical and physical properties is required. One of the important properties is viscosity which plays a key role in design and sizing of CO2-capture equipment.8 Previously reported experimental data on the viscosity of 3A1P are tabulated in Table 1. These studies mostly concern the viscosity changes in a nonaqueous solution of 3-amino-1-propanol. In continuation of our research, this present paper reports new viscosity data for aqueous 3A1P in unloaded and CO2-loaded systems. Experimental data on the viscosity of CO2-loaded solutions for other amines such as ethanolamine, methyl diethanolamine, and piperazine can also be found in the literature.9−14 Correlating experimental data with suitable equations is important alongside measuring accurate new data. As such, a number of methods are available in the literature. In this work, a semiempirical equation as reported by Heric and Brewer15 was employed to represent the viscosity of aqueous 3A1P solution. In the case of carbonated 3A1P solution, the modified Setschenow equation was used.16

that 3A1P exhibits an extra alkyl group. It has been claimed to have a high reaction rate with CO2 which is attractive when dealing with low CO 2 partial pressure gas streams. 5 Quantitative 13C-nuclear magnetic resonance (NMR) spectroscopy experiments reported by Perinu et al.6 also revealed that 3A1P forms a less stable carbamate upon reaction with CO2 in comparison to MEA. In a recent paper by Bentes et al.,7 the overall CO2 absorption process in 3A1P solution was evaluated. © XXXX American Chemical Society

2. MATERIALS AND METHODS The chemicals used in this work are listed in Table 2. They were used without any purification, apart from degassing. Aqueous 3A1P solutions were prepared gravimetrically using an analytical balance from Mettler Toledo XS-403S with a resolution of 1 mg. The Milli-Q water (resistivity 18.2 MΩ· m) was also degassed before being used. The CO2-loaded solutions were prepared by bubbling CO2 gas at a flow rate of 0.15 L·min−1 into the unloaded 3A1P solution. By varying the time of the CO2 bubbling process, five different CO2-loaded samples (between loading values of 0.13 and 0.54 mol of CO2/ mol of MEA) were prepared for each 3A1P concentration studied in this work. Past work shows that there is no significant change in loading when following this procedure. In order to determine the actual CO2-loadings in the prepared solutions, an acid−base titration method as discussed previously was employed.21 Dynamic viscosity was measured using an Anton-Paar Physica MCR 101 rheometer with a double-gap pressure cell XL (DG35.12/PR, measuring cell serial number 80462200) at T = 298.15−373.15 K. A detailed explanation on viscosity measurement in our laboratory has been published recently.22 Viscosity values reported in this work are average values from at least 50 different readings with each set of experiments repeated three times. The experimental data were also corrected against the calibrated values from General Purpose Viscosity Reference Standard S3S as supplied by Paragon Scientific Ltd.

The low AAD values indicate that our data agree well with the literature, and our measuring system is reliable. Table 3 lists the viscosity of aqueous 3A1P solution determined in this work. Viscosities for the unloaded 3A1P solutions were measured at different 3A1P mass fractions ranging from 0.1 to 1.0 at T = 298.15−373.15 K. As can be seen, the viscosity of aqueous 3A1P decreases as temperature increases, as expected. The change in viscosity as a function of 3A1P mole fraction is displayed in Figure 3. In general, viscosity increases with the

a Experiments were performed at different 3A1P mass fractions w1 and temperatures T. The pressure during experiments was maintained by N2 gas (p = 5 bar). Standard uncertainties u are u(w1) = 0.01, u(T) = 0.03 K, and u(p) = 0.002 bar. The combined standard uncertainty for viscosity measurement uc(η) is 0.10 mPa·s.

complex formation. Negative deviation on the other hand may indicate that dispersion forces are primarily responsible for molecule interaction. The change in viscosity deviation from negative in the water-rich region to positive in the amine-rich region was also reported in other aqueous alkanolamine systems such as in ethanolamine, diisopropanolamine, and methyl diethanolamine.24−27 Our recent publication compared four different semiempirical methods for correlating the viscosity of aqueous alkanolamine,22 and in this paper, the method based on the work of Heric and Brewer15 was chosen. In this method, the viscosity of the mixture ηmix is calculated using an equation as follows ln ηmix = x1 ln η1 + x 2 ln η2 + x1 ln M1 + x 2 ln M 2

The viscosities of pure water were taken from Kestin et al.28 The number of parameters Ai may be chosen with a minimum value of i of zero, implying one parameter. Several attempts at optimizing the predicted 3A1P viscosity were made by varying the order of i, and we have concluded that, in the case of aqueous 3A1P, a first order Heric−Brewer equation yields a satisfactory outcome. Values of A0 and A1 at different temperatures are listed in Table 4. The regressed Heric−Brewer parameters were then subjected to a second order temperature dependent polynomial, as shown in eq 5.

Calculated values from 0.30 3A1P mass fraction are shown as ■, ●, ▲, ▼, and ◆ for CO2-loadings of 0.13, 0.25, 0.34, 0.44, and 0.54, respectively. Calculated values from 0.50 3A1P mass fraction are shown as □, ○, △, ▽, and ◇ for CO2-loadings of 0.13, 0.24, 0.32, 0.42, and 0.52, respectively.

In this work, the viscosity of CO2-loaded 3A1P solutions was correlated using the modified Setschenow equation.16 This equation was originally used to explain the salting effects in liquid mixture systems but has also been used to represent physical property relationships of aqueous amine mixtures.29−31 We have recently applied this equation to represent the viscosity of CO2-loaded concentrated MEA solutions.22 This equation was used, as it yielded better data fitting and minimal standard deviation as compared to other tested techniques. The modified Setschenow equation that correlates the viscosity and CO2 concentration is

⎛η⎞ ln⎜⎜ ⎟⎟ = ⎝ ηr ⎠

modified Setschenow equation is able to correlate the viscosity of CO2-loaded 3A1P solution. Larger deviations, albeit lower than 8%, were observed for several data points especially for measurements at higher temperatures.

5. CONCLUSION This work presents new viscosity data for both unloaded and CO2-loaded aqueous 3A1P solutions. Experiments were conducted at different mass fractions and T = 298.15−373.15 K. At all temperatures studied, viscosity decreases with an increase in temperature. The viscosity deviations from linear dependency on mole fraction were similar to previously studied aqueous alkanolamine systems at the water-rich region and at the amine-rich region. A first order Heric−Brewer equation was found to correlate the unloaded 3A1P viscosity satisfactorily. The viscosity of the CO2-loaded solutions was measured at 0.30 and 0.50 3A1P mass fractions at five different CO2-loadings.
