Abstract
This study seeks to validate the aerosol growth models and establish a strategy to remove aerosol by changing specifications and adjusting operating conditions of amine scrubbers. In this study, aerosol growth in CO2 capture absorber using monoethanolamine(MEA) solution was simulated. Absorber profile is obtained from process modeling using Aspen Plus® and is input to gPROMS model for aerosol growth and amine emission calculation, the model was validated by the experiment of bench scale absorber. Given an initial water aerosol size and particle number concentration that is saturated with inlet flue gas content, the results show that the effect of aerosol particle number concentration is significant, the final size of the aerosol decreases as particle number concentration increases, and aerosol growth is inhibited with a very high particle number concentration. An amount of amine being carried out into the atmosphere and also increase with the initial aerosol number concentration.
