Absorption kinetics of carbon dioxide into aqueous ammonia solution: Addition of hydroxyl groups for suppression of vaporization

Solvent effects in the thermal decomposition reaction of ammonium carbamate: A computational molecular dynamics study of the relative solubilities of CO2 and NH3 in water, ethylene glycol, and their mixtures

“…There is a large number of experimental [14][15][16] and theoretical investigations of carbon dioxide capture in ammonia. The reaction kinetics of absorption of CO 2 in aqueous ammonia solutions has been studied at a range of temperatures [16][17][18][19][20][21]. Jeon et al [21] have experimentally shown that hydroxyl additives (including ethylene glycol) enhance the absorption rate of CO 2 in aqueous ammonia as well as reduce the volatility of ammonia.…”

Jeon et al [21] have experimentally shown that hydroxyl additives (including ethylene glycol) enhance the absorption rate of CO 2 in aqueous ammonia as well as reduce the volatility of ammonia. Zwitter-ion mechanism [22,23] was proposed to describe the reaction CO 2 + NH 3 as a two-stage reaction.…”
