for the components of the extraction example given at Examples/ExtractionExample.
These parameters are located in the subheadings under Parameters/Binary Interaction/
Uniq-1. Figure 11.25 shows that the source of most of these parameters is APV70LLE-
LIT (liquid-liquid equilibrium data) but that the data for the methanol-water and
ethanol-water systems are derived from vapor-liquid equilibrium data. The choice of
the source of the data is shown in Figure 11.26. The previous caution about data source
applies here. Are quaternary or ternary data available in the literature for this system?
Do multicomponent results generated by Aspen Plus's stored data agree with experi-
mental data? Note the temperature limitations on the data in Figure 11.25. Simulation
work carried on outside the applicable temperature ranges of the data have potential
for substantial error.
