In this study, the gas phase volumetric overall mass transfer coefficients (KGae) for CO2 absorption into aqueous ammonia solutions were measured to explore the mass transfer performance of a column packed with structured packing. The KGae values were evaluated over ranges of main operating variables, that are, 1400–2300 m3·m–2·h–1 gas flow rate, 20–39 m3·m–2·h–1 liquid flow rate, up to 8 kPa partial pressure of CO2, and 0.27–0.72 kmol·m–3 ammonia concentration. The results show that higher liquid loading and concentration of aqueous ammonia are beneficial to enhance the KGae values. On the contrary, KGae value decreases as the CO2 partial pressure increases. The results also show that gas loading has little influence on KGae. To allow the mass transfer data to be readily utilized, an empirical KGae correlation for this system was developed. Finally, Simulations were made for the absorption of CO2 into aqueous ammonia solutions by using the currently developed computational mass transfer model along with ...
