Abstract

ABSTRACT: Carbon dioxide (CO2 ) absorption from power plant generated flue gas is investigated for CO2 emissions reduction. Amino acid alkaline solvents have the potential to reduce the energy required for solvent regeneration. This project is focused on CO2 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 CO2 absorption in industrial-scale applications.
