AbstractWater as an absorbent for ethylene oxide has been extensively investigated over the past decades, but many issues about this system still remain such as solvent loss, high energy consumption. In this work, a new absorbent ethylene carbonate (EC) was applied and the solubility behaviors of carbon dioxide, ethylene, methane in the ethylene carbonate (EC) were investigated with using static apparatus at temperatures of 313.2, 323.2, and 333.2 K. And the vapor liquid equilibrium(VLE) of ethylene oxide(EO) and EC have been studied with gas chromatography analysis method at temperatures of 333.2, 343.2, and 353.2 K. The NRTL and Wilson models were used to correlate experimental solubility data and VLE data. The conceptual H2O-based and EC-based EO absorption process for EO-containing mixed gas purification was established and optimized with using the regressed NRTL model parameters. The results showed that the purification process of EC used as absorbent could reduce energy consumption 37.6 Gcal/h. (C) 2020 Elsevier B.V. All rights reserved.
