1PVDW model

Figure 3.5.1. VLE correlation of the n-pentane and ethanol binary system with the 2PVDW mixing rule and the PRSV equation of State. Solid lines are the results of correlation with k 2lk2i = 0.195/0,049 at 373 K, 0.2056/0.073 at 398 K, and 0.207/0.096 at 423 K, Short dashed lines are the results of VLE predictions widi k i/k2 = 0.200/0.073 at all temperatures, and the medium dashed lines are 1PVDW model cone-lations presented earlier in Figure 3,4,3. (Data are from Campbell et al., i 987 data files for this system on the accompanying disk are PE373.DAT, PE398.DAT and PE423.DAT.)...

Figure 4.2.2. VLB correlation (dashed lines) of the carbon dioxide and propane binary system at 277, 310, and 344 K with the Huron-Vidal original (HVO) mixing rule with the van Laar excess free-energy model and the PRSV equation of state. The van Laar model parameters used are = A 2/A2 = 1.1816/1.6901. Solid hnes represent the 1PVDW model correlations presented earlier in Figure 3.4.2. (Points are experimental data from the DECHEMA Chemi.stry Data Series, Gmehling and Onken 1977, Vol. 6, p. 589 data files for this system on the accompanying disk are C02C3277.DAT, CO2C3310.DAT and C02C3344.DAT.)...
