“…First, VLLE calculations were compared to the measurements of Pequenín et al − The systems were water–toluene–cyclohexane, water–toluene–hexane, and water–cyclohexane–heptane . The values of HC–HC k ij were determined from SRK correlation of the VLE experimental data: 0.0221 for toluene–cyclohexane, − 0.0117 for toluene–hexane, , and −0.0042 for cyclohexane–heptane . Unfortunately, the focus of their work was the LLE of quaternary systems with an alcohol, so the low mutual solubilities in the absence of the alcohol were not accurately measured.…”

The cubic two-state equation of state was employed for the correlation of measured mutual solubilities of water and 68 hydrocarbons. A new Kabadi−Danner's type mixing rule is presented, in which the water−water dispersive parameter of the cubic part is corrected due to the presence of a hydrophobic solute. The obtained binary parameters for the water−hydrocarbon pairs had a marked relationship with the chemical family (alkanes, cycloalkanes, aromatics, and unsaturated aliphatics) and with the co-volumes. This allowed the development of general correlations to predict these parameters in the case of lack of experimental solubilities. The model's overall deviations from measured data were 12% and 16% for the solubilities of water in hydrocarbons and of hydrocarbons in water, respectively. The temperature and pressure ranges of the correlated data were 273.2 to 550 K and 1 to 1000 bar, respectively. To check model reliability, the correlations were successfully extended to predict bubble pressures and dew temperatures of water−hydrocarbon binaries and ternaries and mutual solubilities in multi-hydrocarbon mixtures.

“…In studies related to the thermodynamics of solutions, the experimental information generated by the binary benzene + hexane, for different properties, has been, and still is, used by researchers in that area as a reference of their investigations; therefore, the choice of this system is justified. Twenty-three useful VLE data series were found in the bibliography [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42], 16 iso-p and 7 iso-T. Figure 3 shows important errors in some of the series [29,31,37] at 101 kPa, with data missing the trend observed in the other series. These are propagated to the T vs x,y representations ( Figure 4(a)).…”

Distillation - Modelling, Simulation and Optimization

The design of processes containing information on phase equilibria must be carried out through a series of steps, experimentation $ verification $ modeling $ simulation. Each of these steps should be rigorously performed to guarantee a good representation of the behavior of the system under study, whose adequate modeling could be used to simulate the corresponding process. To carry out the different previous tasks, two representative systems, extracted from known database, are used. The quality checking of experimental data series is certified through several thermodynamic consistency methods. The modeling is done by applying a multiobjective optimization procedure, which allows to define a solution front (Pareto front) for different sub-models that are established in this work. The fitness of trade-off solutions, obtained from the efficient front, on the design of distillation processes is analyzed through a simulation.

“…At this point in the evaluation, all the tests have been performed except the Gibbs-Helmholtz test which requires the G E IT versus lIT curves. (Myers, 1955) has about the same area ratio as the MRL 8971 set but the scatter rating is only fair based on the G E Ix l x 2 plot. The MRL 22484 set (Saito, 1969) has a fairly good area ratio but both P' errors are large.…”
