摘要：

The high-pressure vapor-liquid equilibria of methanol + propylene was measured experimentally within a temperature and pressure range of 293-373 K and 0.17-3.7 MPa, respectively, using a synthetic method. The system showed a highly non-ideal behavior with positive deviation from Raoult's law. The phase behavior was also modeled by the statistical associating fluid theory (SAFT) and the Soave-Redlich-Kwong (SRK) equations of state. The statistical associating fluid theory correlated the phase behavior of the binary system much better than the Soave-Redlich-Kwong model, especially at higher pressures. For example, the average absolute deviation percent (AAD%) at T=370 K was 1.11% for the SAFT model with k(12) = 0.02088 and 6.75% for the SRK model with k(12) = 0.08035. (C) 2012 Elsevier B.V.
