Chapter 20. Gas–Liquid Reactions: Film Theory Models

Learning Objectives

After completing this chapter, you will be able to:

  • Model systems where a gas is absorbed into a reacting liquid based on the film model.

  • Understand the role of a key dimensionless parameter, the Hatta number, in determining the extent of reaction in the film (fast reactions) relative to that in the bulk liquid (slow reactions).

  • Distinguish the various regimes of absorption for a fast reaction and examine the effect of operating parameters for these cases.

  • Extend and study the modeling of more complex systems by taking an example of simultaneous absorption of two gases.

  • Couple the film model with macro- or meso-models for the reactors in order to set up design equations ...
