Physical Solubility of Carbon Dioxide in Aqueous Alkanolamines via Nitrous Oxide Analogy

Dynamic simulation of MEA absorption process for CO2 capture from power plants

“…If the absorbed gas reacts with the solvent, then the physical equilibrium cannot be directly measured. Due to the chemical reaction that occurs in the solution, the physical solubility of carbon dioxide in alkanolamine solutions cannot be measured using conventional methods (Browning and Weiland, 1994).Therefore, it must be estimated from experimental data reported to systems that are similar, i.e., non-reacting gases. In view of the similarities with regard to configuration, molecular volume, and electronic structure, N 2 O is often used as a non-reacting gas to estimate the properties of CO 2 (Sada et al, 1978;Haimour and Sandall, 1984;Versteeg and van Swaaij, 1988;Al-Ghawas et al, 1989;Littel et al, 1992).…”

Application of a Hydrophobic Polymeric Membrane for Carbon Dioxide Desorption from an Mea-Water Solution

“…In the calculations the experimental values of the Henry's constant for CO 2 in water and MEA under standard conditions are 1.2456 and 1.5732, respectively [13]. The enhancement factor of the chemical reaction of CO 2 in the liquid phase, as defined by DeCoursey [14], was between 20 and 60.…”

Carbon dioxide removal from MEA - water solution on PDMS tubular membrane

“…C L * is the concentration of CO 2 in the liquid phase which is in equilibrium with the gas phase. The experimental values of Henry's constant for CO 2 in water and MEA at standard conditions (STD) are 1.2456 and 1.5732, respectively, (Browning and Weiland, 1994).…”
