Transport Processes and Separation Process Principles, 5th Edition

Chapter 22. Absorption and Stripping

22.0 Chapter Objectives

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

• Calculate the degrees of freedom for a system in equilibrium

• Calculate flows and composition in single and multiple equilibrium contact stages by using both an equilibrium relationship and a material balance

• Use analytical and graphical techniques to calculate the number of stages needed for either an absorber or stripper

• Calculate rates of mass transfer across fluid–fluid interfaces using two-film theory

• Estimate tray efficiency from correlations of mass-transfer coefficients using two-film theory

• State the differences between loading point and flooding point in a packed column

• Estimate the pressure drop across a trayed ...
