Bubble-point measurement for the CO2+diethylene glycol diacrylate and CO2+diethylene glycol dimethacrylate systems at high pressure
TLDR
In this article, the phase behavior data for CO2+Diethylene glycol diacrylate (DEGDA) and DEGDMA systems were measured at five temperatures of (313.2 to 393.2) K and pressures up to 28.3 MPa.Abstract:
Pressure-composition isotherms are measured by using a static apparatus for the phase behavior data for the CO2+diethylene glycol diacrylate (DEGDA) and CO2+diethylene glycol dimethacrylate (DEGDMA) systems. The experiments are performed at five temperatures of (313.2 to 393.2) K and pressures up to 28.3 MPa. The solubility of CO2 for the two systems decreases as the temperature increases at a fixed pressure. The CO2+DEGDA and CO2+ DEGDMA systems exhibit type-I phase behavior. The experimental results for the CO2+DEGDA and CO2+DEGDMA systems are correlated with Peng-Robinson equation of state using a mixing rule.read more
