Solubilities of carbon dioxide in aqueous solutions of triisopropanolamine

The solubilities of carbon dioxide in aqueous solutions of tertiary amine, i.e. triisopropanolamine, have been measured at 313.15, 323.15, and 333-15 K and over the partial pressures of carbon dioxide ranging from I to 3000 kPa. The treated concentrations of aqueous triisopropanolamine solutions are 10 and 30 mass%. The solubilities of carbon dioxide in aqueous 30 mass% TIPA at 333.15 K were compared with those in aqueous solutions of MEA and MDEA. (C) 2003 Elsevier Science B.V. All rights reserved.
