Transport Processes and Separation Process Principles, 5th Edition

Chapter 25. Gaseous Membrane Systems

25.0 Chapter Objectives

On completion of this chapter, a student should be able to:

• Describe, in membrane processes with two gas phases, the three resistances associated with the flux through a membrane

• Explain the differences between a symmetric and an asymmetric membrane

• Describe the three common types of equipment used for gas-permeation membrane processes

• Describe the four ideal flow patterns in a membrane separator and, for each respective model, solve numerically for the membrane area.

25.1 Gas Permeation

25.1A Series Resistances in Membrane Processes

In membrane processes with two gas phases and a solid membrane, similar equations can be written for the case illustrated in, Fig. 24.7-1b. The ...
