摘要：

Experimental vapour liquid equilibrium (VLE) measurements were conducted for an amino acid salt(AAS), 3.5M potassium sarcosinate and an amine amino acid salt (AAAS), the 5.0M sarcosinate salt of 3-(methylamino)propylamine. The study was performed in two VLE apparatuses from 40 to 120 degrees C and for CO2 partial pressures ranging from 0.08 to 995 kPa. Thermodynamic models representing the AAS and AAAS solvent systems were developed using the extended UNIQUAC model. Model results gave a good representation of the partial pressures of CO2 above the solvent systems for all measured temperatures, pressures and CO2 loadings. (C) 2011 Published by Elsevier Ltd.
