Carbon Dioxide Capture: Absorption of Carbon Dioxide in Piperazine Activated Concentrated Aqueous 2-Amino-2-Methyl-1-Propanol

Sukanta K. Dash and Syamalendu S. Bandyopadhyay
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.
