Heat 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...
متن کاملThermo-Physical Properties and Solubility of CO2 in Piperazine Activated Aqueous Solutions of β-Alanine
Carbon dioxide is one of the major greenhouse gas (GHG) contributors. It is an obligation of the industry to reduce the amount of carbon dioxide emission to the acceptable limits. Tremendous research and studies are reported in the past and still the quest to find the suitable and economical solution of this problem needed to be explored in order to develop the most plausible absorber for carbo...
متن کاملMNDO Study of Nitrogen Atom Inversion in Piperazine, N,N'-Dimethylpiperazine and N,N'-Dichloropiperazine
MNDO semi-empirical SCF MO calculations are used to study the pyramidal nitrogen atom inversion and configurational equilibria in the title compounds.
متن کاملCalorimetric 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...
