FIGURE 4.
Ternary phase diagram of SF, SA, and water at 25°C showing the conversion of tie lines to the “true precipitate” point and the region of variability in the zoom detail. Feed (■), SF-rich phase in red (▲), SA rich-phase in blue (🌑) connected by tie lines (—) and region of variability (—⋅—). All the concentrations are given in mass fraction.
