Kinetics of CO₂ Absorption in MEA+DETA Blended Amine Solutions

Abstract:

The kinetics of CO₂ absorption in unloaded aqueous MEA, MDEA, DETA single amine solutions and MEA+DETA blende amine solutions was studied with the amine concentrations of 3.0 kmol/m³ and at temperatures ranging between 298K and 338K. A dynamic model of CO₂absorption rate on the basis of the static absorption experimental results was established. The reaction rate constant of CO₂ absorption in blended amine solutions MEA+DETA is , and its activation energy is 32.89KJ/mol.
