Separation Process Engineering, 5th Edition

Chapter 20

Introduction to Adsorption, Chromatography, and Ion Exchange

In the first 14 chapters, we looked at separation techniques such as distillation and extraction that are often operated as steady-state, equilibrium-staged separations. Exceptions were batch distillation in Chapter 9 and batch extraction in Section 13.6. In Chapters 17 and 18, we studied crystallization from solution and from melt for both batch and continuous processes. Outlet concentrations can be found from equilibrium calculations, but crystal size distributions required population balances. In Chapter 19, we studied membrane separations that are not operated as equilibrium processes; however, well-mixed membrane separators are analogous to flash distillation, and staged ...
