In present study, the solubility of carbon dioxide has been determined in aqueous potassium lysinate solutions for a wide range of pressure (150 – 4040 KPa), temperature (313.15 – 353.15K) and concentration (1 – 2.5 M). It was found that lysine has good absorptive capacity for carbon dioxide and is comparable to conventional alkanolamines. An enhanced Kent Eisenberg model developed for high pressure vapor-liquid equilibrium data has been used to correlate carbon dioxide solubility in aqueous potassium lysinate solutions. The model results are coherent with experimental findings.
