Solubility of CO2 in the solvent system (water plus monoethanolamine plus triethanolamine)
This report presents a new set of values for the solubility of carbon dioxide in the solvent system (water (1) + monoethanolamine (2) + triethanolamine (3)) at T=(313.2, 333.2, 353.2, and 373.2) K and CO2 partial pressures ranging (1.0 to 120) kPa. The results are specific to solvent systems with the following compositions: (i) omega(2)=0.24, omega(3)=0.06, (ii) omega(2)=0.18, omega(3)=0.12, (iii) omega(2)=0.12, omega(3)=0.18, (iv) omega(2)=0.06. omega(3)=0.24, and (v) omega(2)=0, omega(3)=0.30, where omega refers to the mass fraction of the component. The results fit the Deshmukh and Mather model well. (C) 2009 Elsevier Ltd. All rights reserved.
