Mathematical Preliminaries
In this chapter we consider the issue of computing the solution of a system
Calculate the flow rate and composition of the two effluent phases
produced, when 1,000 kg/h of a solution, containing 50% of solute A
and 50% of solvent C, is contacted in an ideal stage with 1,500 kg/h of
pure new solvent B. In the equilibrium data give
The operation may be followed on the diagram shown below.
Adding B1 to F produces a mixture M1 in the extraction stage, on settling this forms the
equilibrium phases E1 and R1 joined by the tieline through M1.
The total mass balance in the extractor is:
Introduction to LiquidLiquid Extraction
Liquidliquid extraction (also known as solvent extraction) involves the separation
of the constituents (solutes) of a liquid solution by contact with another insoluble
liquid. Solutes are separated based on their

The graphical solution consists on a step
by step construction.
We know that x1 is at equilibrium with y1.
It is then easy to set x1 on the diagram.
We also know that x1 and y2 are at the same
point on the operating line, since they
Principles of LiquidLiquid Extraction
Extraction involves the use of at least 3 components and generally all 3
components appear at least to some extent in both phases. The graphical
way to represent concentrations in ternary (i.e. 3components) systems
Example:
It is desired to absorb 90% of the acetone in a gas containing 1.0 mole%
acetone in a countercurrent tray column. The total inlet gas flow is 30.0 kmol
h1, and the total inlet water (pure) is 90.0 kmol h1. The process operates
isothermally at

40oC is to be continuously flash vaporized to vaporize 60 mole % of the
feed. The residual liquid product contains 35 mole % benzene. If the

Example: It is desired to absorb 90% of the acetone in a gas containing 1.0 mole%
acetone in air in a countercurrent tray column. The total inlet gas flow to the column
is 30.0 kmol h1, and pure water is to be used to absorb the acetone. The process is
