Absorption of carbon dioxide into aqueous methyldiethanolamine

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

“…Therefore, the Henry's constant of CO 2 is expressed as the following form, respectively. Haimour and Sandall (1984) confirmed the N 2 O analogy in their study to measure the solubility of CO 2 in MDEA solution.…”

“…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). Therefore, the Henry's constant of CO 2 is expressed as the following form, respectively.…”

CO2 Solubility in Electrolyte Solution of Potassium Carbonate with the Addition of Promotor Amines (MDEA-DEA/ PZ-DEA) at Various Temperatures

“…The apparatus used in this study was based on the apparatus used by Haimour and Sandall [10] and Al-Ghawas, et al [15]. It has been described and validated in our previous study [16].…”

“…The most important parameter to determine the equilibrium concentration in the liquid phase and the CO 2 absorption rate is the physical solubility of CO 2 [4,10]. These data are required as a reference for designing absorption columns for industry.…”

“…Physical solubility of CO 2 in amine solvent cannot be measured directly due to a chemical reaction between CO 2 and amines. CO 2 reacts rapidly with amine so that the physical solubility cannot be determined [4,10]. Therefore, Clarke [11] used the nitrous oxide (N 2 O) analogy method to estimate the solubility of CO 2 gas in amine solvent.…”
