Fig. 10.6 represents the composition of the vapor and liquid phases at the maxiimmi pressure at which tlie phases can coexist in the ethanehi-heptane system. The composition is about 77 niol-% etliane and the pressure is about 87.1 bar. The corresponding point on Fig. 10.5 is labeled M. A complete set of consistent phase diagrams for tliis system has been prepared by Barr-David. ...

Figure 4.3.9. Comparison of VLB predictions of the 2-propanoi and water binary system at 353 K from the Wong-Sandler (solid lines) and Huron-Vidal original (dashed lines) models with both model parameters obtained by fitting the experimental data at 303 K. Points are the experimental data of Barr David and Dodge 1959.

Figure 4.4.7. VLE correlations of the 2-propanol and water binary system at 523 K with various approximate EOS-C models. Clockwise from top left HVOS, MHV2, MHVl, and LCVM mixing rules combined with the van Laar excess free-energy model and the PRSV equation of state. Solid lines represent correlations with the van Laar parameters fit to experimental data, and the dashed hnes are predictions using van Laar parameters obtained from the DECHEMA tables at 303 K. Points are the VLE data at 523 K from Barr-David and Dodge 1959,...

In the remainder of this section we examine several EOS-G models using three prototype binary mixtures that form sti ongly nonideal solutions. For comparison, we also include the predictions of the UNIFAC model used directly in the y-(p method wherever applicable. The systems considered are the methanol and benzene (Butcher and Medani 1968), the acetone and water (Gmehling and Onken 1977), and the 2-propanol and water (Barr-David and Dodge 1959) binary mixtures. Note that there are many systems with small to moderate solution nonideality for which all or most of the methods mentioned above work reasonably well. We are not concerned with such systems here because the method selection would not be a problem in such cases. Rather we consider only those systems that are more nonideal and for which the differences between the models discussed here are clearly evident. 

Figure 5.1.11. VLB predictions for the 2-propanol and water binary system at 523 K using the UNIQUAC method with the EOS-G models, and parameters obtained at 298 K. The solid line reflects the results of the WS model. The large, medium, and short dashed lines are from the HVOS, HVO, and MHVl models, respectively the dotted line is from the MHV2 model and the dot-dash line denotes the results of the LCVM model.
