Title: CO 2 absorption from simulated flue gas in a bubble column

Abstract

Carbon dioxide (CO 2) absorption from power plant generated flue gas is studied for CO 2 emissions reduction. Amino acid alkaline solvents have the potential to reduce the energy required for solvent regeneration. Here, we focus on CO 2 absorption by amino acid alkaline solvents in a bubble column. Important parameters characterizing the reactor, e.g., bubble size, liquid-phase dispersion coefficient, and gas holdup, are experimentally determined. A theoretical model based upon transient mass and energy balances for the chemical species involved is presented. Simulation results are compared to experimental data. The model can be used to predict, optimize, and control CO 2 absorption in industrial-scale applications.
