Aqueous amines as the solvents for CO2 removal in low concentration streams have been exhaustively studied. This work focuses on the blending of piperazine (PZ) activator with aqueous tertiary amines (Methyldiethanolamine, MDEA) across concentration range of 200-900mol/m3 for MDEA and 5-41mol/m3 for PZ and sterically-hindered amines (2-amino-methyl-1-propanol, AMP) across concentration range of 6-24mol/m3...
Kinetics of the reaction of CO2 and ethylethanolamine (EMEA) in aqueous solutions has been studied using the stopped-flow technique with conductivity detection. Measurements were performed at 288 K, 293 K, 298 K, and 303 K. Amine concentration ranged from 10 mol m−3 to 37.5 mol m−3. The termolecular mechanism was applied to interpret the kinetic data. In this mechanism, carbamate formation occurs...
