Chapter 21. Gas–Liquid Reactions: Penetration Theory Approach

Learning Objectives

After completing this chapter, you will be able to:

  • Model gas absorption with reaction on the basis of the penetration theory.

  • See the differences between the predictions of the film model and the penetration model.

  • Understand the use of laboratory-scale contactors with well-established hydrodynamic patterns to find physico-chemical parameters such as rate constant and diffusivity.

Analysis of gas–liquid reactions based on the film model was studied in Chapter 20. An alternative model for mass transfer from a gas–liquid interface is the penetration theory model, which was introduced in Section 8.8. Here we present an analysis of gas–liquid reactions based on ...
