Investigation of thermophysical properties of CO2-loaded 2-loaded aqueous 2-(isopropylamino)ethanol (IPAE) solution at T = (298.15 to 333.15) K

New and effective absorbents are in demand to enable the practical implementation of global CO2 2 capture to mitigate global warming. One promising approach involves exploring sterically hindered amine solvents. Secondary amines, particularly 2-(isopropylamino)ethanol (IPAE), have been suggested as potential candidates for CO2 2 capture. This study presents novel experimental data on the thermophysical properties of aqueous IPAE solutions, including density and viscosity. These findings are crucial for the design of carbon dioxide (CO2) 2 ) absorption and regeneration columns. The measurement was conducted at different mass fractions (0.3, 0.4, and 0.5) under 0.1 MPa pressure and T = (298.15 to 333.15) K. Utilizing the measurement data, thermal expansion coefficient, diffusion coefficient, and viscosity activation energy values were computed which provide valuable insights. The investigation reveals that the density and viscosity of aqueous IPAE solution increases with CO2 2 loading and decrease with increase in temperature. This research holds importance, as it could lead to advancements in solvent technology, contribute to global CO2 2 capture efforts, aid in the design of carbon capture systems, promote sustainability, and advance our understanding of solvent properties in environmental applications.
