Chapter 13. Liquid-Liquid Extraction

13.0 Summary—Objectives

In this chapter we consider what extraction is used for, develop McCabe-Thiele and Kremser methods for immiscible extraction, and explore methods for ternary partially miscible extraction systems. At the end of this chapter, you should be able to satisfy the following objectives:

1. Explain what extraction is and outline the types of equipment used

2. Apply the McCabe-Thiele and Kremser methods to immiscible extraction

3. For partially miscible extraction, plot extraction equilibria on a triangular diagram. Find the saturated extract, saturated raffinate, and conjugate lines

4. For partially miscible extraction, find the mixing point and solve single-stage and cross-flow extraction ...
