Density Measurements of Unloaded and CO₂-Loaded 3-Amino-1-propanol Solutions at Temperatures (293.15 to 353.15) K

Abstract

The first part of this work presents experimental density data of aqueous 3-amino-1-propanol (3A1P) solutions at different compositions and temperatures of (293.15 to 353.15) K. It was found that densities decreased with increasing temperatures and were concentration dependent. Excess molar volumes of aqueous 3A1P were also established. Five different methods were compared for correlating density data of unloaded 3A1P solutions. In the second part of this work, densities of CO 2 -loaded solutions were measured at 0.1 and 0.5 mass fractions of 3A1P at increasing temperatures and CO 2 -loadings. Two different models were used to regress these experimental data. The suitability of these methods to represent densities of unloaded and CO 2 -loaded 3A1P solutions is evaluated.

Density, Viscosity, and Excess Properties of Ternary Aqueous Mixtures of MDEA + MEA, DMEA + MEA, and DEEA + MEA

“…Bernhardsen and Knuutila [4] reviewed the potential amine solvents for CO2 absorption process by considering the absorption capacity, cyclic capacity, and pKa. The studies performed on 3-amino-1-propanol (3A1P) [5,6] and diethylenetriamine (DETA) [7,8] stated the possibilities of using them as solvents in post-combustion CO2 capture. The applicability of this technology to post-combustion CO2 capture is challenging owing to the economic feasibility of the process due to the high-energy penalty in the CO2 stripping.…”

Density and Viscosity Correlations for Aqueous 3-Amino-1-propanol and Monoethanol Amine Mixtures

“…This approach requires a higher number of parameters to correlate to acquire high accuracy of data fit (Aronu et al, 2012). Such studies are reported for densities of aqueous MEA and 3A1P solutions under different compositions and temperatures in the literature (Han et al, 2012;Idris and Eimer, 2016).…”

“…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.…”

“…The estimated parameters are given in Table 1. Idris and Eimer, (2016) reported several density correlation studies based on a Redlich-Kister type polynomial on excess volume, Jouyban-Acree (Jouyban et al, 2005) and Gonzalez-Olmos and Iglesias (Gonzalex-Olmos and Iglesias, 2008). Table 2 summarize absolute average deviations of different correlations fitted for the aqueous 3A1P solutions.…”

“…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).…”
