摘要：

Phase equilibria and saturated density for ethylene + methanol system at high pressures were measured at 278.15 K and 283.65 K with a static-circulation apparatus. The experimental apparatus equipped with three Anton Paar DMA 512S vibrating tube density meters was previously developed for measuring vapor-liquid-liquid equilibrium at high pressures. Coexisting phase composition and saturated density of each phase can be measured by means of the apparatus with a maximum temperature and pressure of 400 K and 20 MPa, respectively. The present experimental results include vapor-liquid, liquid-liquid, and vapor-liquid-liquid equilibria. The equilibrium composition and saturated density of each phase were determined by gas chromatograph and vibrating tube density meters, respectively. The experimental data were correlated with various equations of state.
