Calorimetric Measurements of CO2 Absorption into Aqueous -Methyldiethanolamine Solutions
A reaction calorimeter was used to study the rate and heat effects during CO2 absorption into aqueous solutions of N-methyldiethanolamine (MDEA). The experiments were carried out at constant pressure of 0.1 MPa and 0.3 MPa over a range of temperature from 293 K to 333 K. The amine content changed from 10 to 30 mass %. The experimental equipment and procedure were described with the emphasis on ...
متن کاملKinetics of the Reaction of Pure CO2 with N-Methyldiethanolamine in Aqueous Solutions
The process of pure carbon dioxide absorption is analyzed in aqueous solutions of N-methyldiethanolamine (MDEA). The experiments were made in a stirred tank reactor with a plane and known interface area. The variables considered were the MDEA concentration within the range 0.1–3.0 M and the temperature in the interval 288–313 K. From the results, we deduce that the process takes place under iso...
متن کاملCorrelation and Prediction of Solubility of CO2 in Amine Aqueous Solutions
The solubility of CO2 in the primary, secondary, tertiary and sterically hindered amine aqueous solutions at various conditions was studied. In the present work, the Modified Kent-Eisenberg (M-KE), the Extended Debye-Hückel (E-DH) and the Pitzer models were employed to study the solubility of CO2 in amine aqueous solutions. Two explicit equations are presented to evalu...
متن کاملSolubility of CO2 in Aqueous Solutions of Diethanolamine (DEA) and Choline Chloride
In this study, the solubility of CO2 in DEA in the presence and absence of choline chloride was reported at different temperatures of 276.15, 298.15, 313.15, and 333.15 K, and pressure range of 4-15 bar. The solubility of CO2 was evaluated using the pressure decay method in a batch isochoric stirred absorption cell. Also, the design of experiments performed with Qualitek-4 software using the Ta...
متن کاملHeat effect on mass transfer in N-methyldiethanolamine aqueous solutions
A bubble column was used to study the heat effect on CO2 absorption in methydiethanolamine solutions and on volumetric mass transfer coefficient. It was found that the temperature varied until 4 oC between the beginning and the end of the process. Our studies provide an empirical correlation type Boltzmann to estimate the temperature at different amine concentration (0-1M) and gas flow rate (10...
