Transport Processes and Separation Process Principles, 5th Edition

Chapter 28. Adsorption and Ion Exchange

28.0 Chapter Objectives

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

• Outline the steps that make up a typical adsorption process

• Compare three types of isotherms given in the text that are used for correlating adsorption-equilibria data

• Explain the concept of the width of the mass-transfer zone and break point

• Calculate from experimental data the total bed height needed for fixed-bed adsorption

• Recognize that the techniques used in ion exchange so closely resemble those used in adsorption that, for the majority of engineering purposes, ion exchange can be considered as a special case of adsorption
