Reaction rate constants of aqueous AMP and ammonia solutions with carbon dioxide (CO2) and sulfur dioxide (SO2) were determined from the measurements of their absorption rates. The absorption characteristics of an NH3 solution added to AMP for CO2 and SO2 was investigated using an agitated vessel. The results showed that the addition of NH3 to AMP significantly increased the absorption rates of AMP. Also, it increased the reaction rate constants of AMP with CO2 and SO2 by 144% and 109% respectively. The reaction rate constants were given by k2,A1 = 2.357×1010 exp(-5028.17/T) and k2,A2 = 3.772×109 exp(-4283.71/T), respectively.
