= volume fraction occupied by the dispersed phase = volume fraction occupied by the continuous phase What is the minimum mass of pure MIBK required? Liquid-Liquid Extraction: Sizing Mixer-settler Units We want our raffinate to contain no more than 5.0 wt% acetone. We have a 1000 kg/hr feed that contains 30 wt% acetone and 70 wt% water. Note the composition of species at this location. The intersection of these two lines is mixing point. Draw one line connecting points and and another line connecting points and.

On a fresh copy of the phase diagram, label points, , and.

Draw a line from to F and extend to the other side of the equilibrium curve. Extend the upper-most tie-line in a line that connects with the line connecting points ( and ).Locate points and on the phase diagram.is the intersection of the line connecting points (, ) and the line that is an extension of the upper-most equilibrium tie-line.Р”Вetermining minimum feasible solvent mass ratio ( ) when (1) feed composition (2) incoming solvent composition and (3) outgoing raffinate composition have been specified/selected. = Point associated with the minimum feasible for this feed, solvent and (raffinate or extract) composition. = Mass fraction of species in the extract leaving stage = Minimum feasible mass ratio to achieve the desired separation, assuming the use of an infinite number of stages. Every pair of passing streams must be connected by a straight line that passes through. Points ( and ) and ( and ) are connected by a straight line passing through. This is where the fresh solvent enters the system and the final raffinate leaves the system.

Watch this two-part series of videos from LearnChemE that shows how to use the Hunter Nash method to find the number of equilibrium stages required for a liquid-liquid extraction process. РІР‚вЂњ Continue in this manner until the extract composition has reached or passed. Connect to operating point with a straight line, mark the location of. Connect point to operating point with a straight line, mark the location of.

Determine the number of equilibrium stages required to achieve the desired separation with the selected solvent mass.

Note the intersection of these two lines and label as РІР‚Сљ РІР‚Сњ.

On a fresh copy of the graph, with plenty of blank space on each side of the diagram, note the location of points, , and (specified/selected) and (determined in step 3).

Draw a straight line from to and extend to find the location of on the equilibrium curve.

Locate point on the ternary phase diagram.

Use this composition to locate point along the straight line connection points and.

Do a material balance to find the composition of one species in the overall mixture.

This could refer to the mass of the stream or the composition of the stream. is expected to be located outside of the ternary phase diagram. Every pair of passing streams must be connected by a straight line that passes through point. is determined by the intersection of the straight line connecting points (, ) and the straight line connecting points (, ). will be located within the ternary phase diagram.
