Thermal Effects During the Absorption of CO2 in Aqueous Solutions of 3-Amino-1-Propanol

Density, Speed of Sound, Isentropic Compressibility, and Excess Volume of Binary Mixtures of 1-Amino-2-propanol or 3-Amino-1-propanol with 2-Amino-2-methyl-1-propanol, Diethanolamine, or Triethanolamine from (293.15 to 323.15) K

“…Other amines, such as di-isopropanolamine (DIPA), 1-amino-2-propanol (MIPA), or 3-amino-1-propanol (AP), have also been used, and some papers about these processes have been published. [1][2][3][4] The use of mixtures of two alkanolamines (mainly aqueous solutions of a tertiary alkanolamine with a primary or secondary alkanolamine) has also been proposed with the aim of substituting at the industrial level the solutions of a single alkanolamine. 5,6 To fully characterize the physicochemical behavior of new formulations of solvents, it is important to create a database on those thermophysical properties that are relevant for the design, operation, and optimization of sour gas treatment plants.…”

“…Some of the most important alkanolamines used in industrial processes include monoethanolamine (MEA), diethanolamine (DEA), triethanolamine (TEA), 2-amino-1-methyl-1-propanol (AMP), and N -methyldiethanolamine (MDEA). Other amines, such as di-isopropanolamine (DIPA), 1-amino-2-propanol (MIPA), or 3-amino-1-propanol (AP), have also been used, and some papers about these processes have been published. − …”

Effect of temperature on carbon dioxide absorption in monoethanolamine solutions

“…When CO 2 is absorbed at reduced partial pressures in aqueous solutions of alkanolamines, these effects have been considered negligible and have disregarded [4][5][6][7]. Nevertheless, if the absorption is carried out at high partial pressures of CO 2 the thermal effects appear to be considerable [8,9].…”

Solubility of Carbon Dioxide in Deep Eutectic Solvents Based on 3-Amino-1-Propanol and Tetraalkylammonium Salts at Low Pressure

“…However, according to Astarita and other authors [ 33 , 34 ], the latter reaction is negligible due to the conditions needed and the main product of the reaction is carbamate. The molecule 3-amine-1-propanol follows the mechanism presented in Figure 9 .…”

“…The reaction results in the temperature rise at the interfacial film. According to Camacho [ 34 ] it is dependent on the AP concentration and can be significant at certain conditions and can cause evaporation to the gas phase.…”
