Separation Process Engineering, 5th Edition

Chapter 14

Washing, Leaching, and Supercritical Extraction

A number of other separation processes can be analyzed, at least under limiting conditions, using McCabe-Thiele diagrams or the Kremser equation with an approach very similar to that used for absorption and stripping. These processes all require addition of a mass-separating agent. If flows are not constant, triangular diagram methods developed for extraction can often be extended to these separations. The triangular diagram method is developed for leaching (or solid-liquid extraction) in Section 14.4.

14.0 Summary—Objectives

In this chapter we look at general applicability of McCabe-Thiele, Kremser, and triangular diagram analyses and apply them to washing and leaching. At the end ...
