摘要：

The high-pressure vapor-liquid equilibria of a CO2-ethanol-water system was measured using a flow-type device at temperatures of 313-353 K and a pressure of 8 MPa. With the obtained vapor-liquid equilibria data and the data of previous report (Sato et al., 2019), the applicability of a correlation method using the van der Waals one fluid (vdW1) mixing rule and Wong-Sandler (WS) mixing rule in the Peng-Robinson equation of state was confirmed. From an estimation made using the temperature-dependent approximation formula of fitting parameters determined by the cor-relation, the applicability of both the vdW1 mixing rule and WS mixing rule to CO2-ethanol-water systems was sug-gested.
