Aqueous monoethanolamine (MEA) solutions are the most frequently used chemical absorbents because of high reactivity to such chemicals as carbon dioxide and hydrogen sulfide. However, the highly MEA-concentrated aqueous solution cannot be solely used for the removal of acid gases, since it can react with unrelated materials such as reactor vessels, tubing lines, and several process compartments. Densities and viscosities of mixtures of monoethanolamine (MEA) + ethylene glycol (EG) + water were measured at temperatures of (30, 40, 50, 60, and 70) C. The concentration ranges were 0 to 84.7 mass % for both water and EG at 15.3 mass % MEA and 0 to 70.0 mass % for both water and EG at 30.0 mass % MEA. The experimental values were correlated as functions of temperature. The maximum deviations were less than 0.01% for densities and 0.4% for viscosities.
