چکیده انگلیسی
Additionally, the absorption of CO2 into aqueous solutions of DEEA activated with N-(2-aminoethyl) ethanolamine (AEEA) is studied at 303Â K. Three formulated solvents (2Â M DEEAÂ +Â 0.1Â M AEEA), (2Â M DEEAÂ +Â 0.2Â M AEEA) and (2Â M DEEAÂ +Â 0.3Â M AEEA) were investigated. The enhancement factor in the blended solution is significantly higher than for the pure DEEA solution. The overall reaction in amine blends can be regarded as a reaction between CO2 and DEEA in parallel with the reaction of CO2 with AEEA. It has been proven that the kinetic rate constants for the CO2 reaction with DEEA and AEEA, which were determined using the present experimental technique, can satisfactorily predict the measured kinetics for the aqueous amine blends DEEA/AEEA under pseudo-first-order regime.
