The influence of 2-amino-2-methyl-1-propanol and tri(hydroxymethyl)aminomethane on CO2 absorption kinetics and mass transfer in ammonia solution |
| 초록 |
The main issue in CO2 absorption using aqueous ammonia is to reduce ammonia vaporization. The methods to suppress the ammonia vaporization have been proposed using 2-amino-2-methyl-1-propanol and tri(hydroxymethyl)aminomethane. However, there are little researches on the effects of using additives with ammonia solution for CO2 absorption. Therefore, this study investigated the influences of these additives in aqueous ammonia on CO2 absorption kinetics and mass transfer using wetted wall column. The reaction rate constants in additive-containing absorbent were higher than those in additive-free solution, which were under 10wt% of the ammonia concentration region. However, flipped results were observed for the ammonia concentration region above 10wt%. The overall mass transfer coefficients showed similar tendencies as the reaction rate constants. With these results, we concluded that CO2 absorption kinetics and mass transfer under low ammonia concentration region can be enhance by these additives in aqueous ammonia. |
