Solubilities of Carbon-Dioxide in Aqueous Mixtures of Diethanolamine and 2-Amino-2-Methyl-1-Propanol
The gas solubility of CO2 has been measured in aqueous mixtures of diethanaolamine and 2-amino-2-methyl-1-propanol at (40, 60, and 80)degrees C and in the pressure range (10 to 300) kPa. The concentrations of the amine mixtures were 6 mass % diethanolamine (DEA) + 24 mass % 2-amino-2-methyl-1-propanol (AMP), 12 mass % DEA + 18 mass % AMP, and 18 mass % DEA + 12 mass % AMP. The solubilities show a systematic change as the composition of the aqueous mixtures varies.
