In particular, the nature of the cosolvent flood depends primarily on the position of the cosolvent injection concentration relative to a critical tie line extension which passes through the plait point . 1a lies close to the oil corner of the diagram. It represents a condition where the 3-component mixture separates into two phases, but the phases have identical compositions. Construction of pseudo-ternary phase diagram is an important tool to assess the effect of different formulation component on in-vitro performance. Ternary phase diagrams give the precise and accurate data of the various composite component systems and are utilized in several areas of pharmaceuticals like the formulation of . Plait Point is the point where the raffinate phase and extract phase both have same composition. . Our maximum number of Phases is P=3. As it can be seen from Fig. Figure 5.4. Phase diagrams are graphical representations of the liquid, vapor, and solid phases that co-exist at various ranges of temperature and pressure within a reservoir.
The point of intersection is the plait point. There is fascinating Alternation Rule that emerges from the Gibbs Phase Rule that tells us adjacent phases regions can only decrement/increments in units of "1". This simple representation of the ternary phase diagram is valid for low temperatures; i.e., before reaching the closed loop region. 8. Ternary phase diagrams could be drawn with mole fractions or mass fractions. The plait point in Fig. Ternary phase diagrams represent the phase behavior of mixtures containing three components in a triangular diagram. In the present work, the liquidliquid ternary phase diagram for a commercial biodiesel/glycerol/methanol system was experimentally determined at 20 C. a) Determine the composition of the Plait Point, P, marked on the ternary diagram of the | SolutionInn Answer to n Consider the given ternary phase diagram on the mass fraction basis. .

Ternary phase diagrams represent the phase behavior of mixtures containing three components in a triangular diagram. Two-phase regions are areas enclosed by black . So for our ternary phase diagram, F=2, C=3. It is concluded that the one-dimensional performance of a cosolvent flood can be predicted largely by inspection of the ternary phase diagram. Plait Point, and it is another example of a critical point, where the composition of the two phases is equal The m-phase is the micelle-formation phase. 9. A ternary system consists of three components. The result is a 3D virtual application which students can use for interacting in real time with a ternary diagram, e.g. This point is located near the top of the two-phase envelope, at the inflection point. It provides scientific basis for the selection of different components and in-vitro performance of optimized formulation can be correlated with its in-vivo efficacy. The OthmerTobias plot was also used to predict the plait point, which was determined to be 60.2% biodiesel, 39.1% methanol, and 0.7% glycerol (by mass). A tie line in a ternary phase diagram connects the two phases existing in equilibrium. Figure 5.6 shows an example of a ternary phase diagram. This would include points in the two regions, on the solubility curve and at the plait point. Made by faculty at the University of C. acetic acid form the "binodal curve"; on this curve the "plait point", indicated as P, is defined as the point at which the binodal compositions are identical.
