What is plait point in ternary equilibrium?

The Plait Point P, is the intersection of the raffinate-phase and extract-phase boundary curves. At this point, the equilibrium phases become coincident and no separation can be made at that point.

How do you find the plait point on a ternary phase diagram?

Take each endpoint and draw a line from it downward, perpendicular to base of the triangle. The extensions from the raffinate side will intersect those from the extract side, and each pair forms a point on the conjugate curve. The final point is the plait point.

What is ternary liquid liquid equilibrium?

Ternary liquid equilibrium data at 30°C are presented for the systems containing water and methyl isobutyl carbinol with formic, acetic, propionic and butyric acids respectively as solutes. The tie-line data have been correlated by the method of Hand.

Which of the following conditions are valid at the plait point?

Which of the following conditions are valid at the plait point? Solution: Plait point signifies the condition at which the composition of two liquid phases in equilibrium become identical and indeed transforms to a single phase.

What is the number of plait point for a ternary system containing two pairs of partially miscible liquids?

Answer is 0, as no plait point can exist in the ternary diagram where two pairs of partially miscible liquids exist. Agree, right Answer is Zero.

How do you tie a liquid liquid extraction line?

Note 2: To draw a tie line, simply from point g at extract layer, move vertically downwards through 45o line, then move horizontally to the equilibrium line and finally move vertically upwards to point i at raffinate layer. A line connecting point g and i is the tie line.

What is Binodal curve in ternary phase diagram?

To differentiate within the two-phase region and single-phase region in the ternary diagram, pressure and temperature must be fixed. There will be different envelopes (binodal curves) at different pressures and temperatures. The binodal curve is the boundary between the 2-phase condition and the single-phase condition.

What is ternary mixture?

A ternary mixture of water, oil, and a surfactant, is characterized by the formation of microscopic scale structures, so called micelles. The formation of micelles, their type, and the development of excess phases is influenced by temperature and concentration (Figure 2, left).

What is selectivity in extraction?

Selectivity also indicates the ease of extraction of a solute from the raffinate phase, and higher selectivity corresponds, theoretically, to fewer stages required for a given separation and less raffinate in the extract.
