Abstract—In this work new experimental data on the rate of
absorption of CO2 into PZ activated concentrated aqueous
AMP in the temperature range of (323–333) K are presented.
Rate activator PZ is used with a concentration of (2–8) wt%,
keeping the total amine concentration in the solution at 50 wt%.
The vapour-liquid equilibrium (VLE) of CO2 into aqueous
solutions of (AMP+PZ) have also been measured and modeled
in order to determine the liquid phase speciation of
(AMP+PZ+CO2+H2O) system and equilibrium CO2 loading.
The theoretical absorption-rate model used to interpret the
experimental kinetic data is based on all possible chemical
reactions in the liquid phase. The average absolute deviation
between the experimental and model results is about 6.8 %.
Index Terms—CO2 capture, 2-Amino-2-methyl-1-propanol,
piperazine, diffusion-reaction model.
