Aqueous ammonia can act as an alternative absorbent for CO2 removal, but it has high volatility and reduces the ammonia concentration. We analyzed the hydroxyl additives 2-amino-2-methyl-1-propanol (AMP), ethylene glycol, and glycerol to reduce the vapor pressure of ammonia solutions. In addition, absorption efficiency groups of aqueous ammonia solutions containing hydroxyl additives were investigated. The results show that the addition of AMP, ethylene glycol, or glycerol to NH3 reduced the vapor pressure of the absorbent by 14.0%, 22.7%, and 75.2%, respectively. The reaction rate constants of aqueous NH3 containing AMP, ethylene glycol, and glycerol additives at 293, 303, 313 and 323 K are given by k2, NH3/AMP=4.565×105 exp(-1396.5/T), k2, NH3/ethylene glycol=1.499×106 exp(-1978.7/T) and k2, NH3/glycerol=7.078×106 exp(-2413.3/T), respectively.
