Solubility of Carbon-Dioxide in Monoethanolamine Plus Ethylene-Glycol Plus Water and Monoethanolamine Plus Poly(Ethylene Glycol) Plus Water
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 2500 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.
