The removal of carbon dioxide by using chemical absorbents has been of great interest, since it was found that the global warming effect is primarily due to excessive discharge of carbon dioxide and methane. The solubility of carbon dioxide in monoethanolamine (MEA) + ethylene glycol (EG) + water and monoethanolamine (MEA) + poly(ethylene glycol) (PEG) + water has been measured at 313.2 K and at partial pressure ranges of carbon dioxide up to 2,500 kPa. The concentrations of aqueous mixtures are 15.3 mass % MEA + 15.3 mass % EG, 15.3 mass % MEA + 42.3 mass % EG, 15.3 mass % MEA + 15.3 mass % PEG, and 15.3 mass % MEA + 42.3 mass % PEG. In each case, the solubility was represented as functions of partial pressures of carbon dioxide.
