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 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 solve numerically for the membrane area for each respective model.

25.1 Gas Permeation

25.1 A 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. 24.8-lb. The equilibrium ...
