Chapter 5: Introduction to Multicomponent Distillation
Binary distillation problems can be solved in a straightforward manner using a stage-by-stage calculation that can be done either on a computer or graphically using a McCabe-Thiele diagram. When additional components are added, the resulting multicomponent problem becomes significantly more difficult, and the solution may not be straightforward. In this chapter we will first consider why multicomponent distillation is more complex than binary distillation, and then we will look at the profile shapes typical of multicomponent distillation. In Chapter 6, matrix calculation methods will be applied to multicomponent distillation, and approximate methods will be developed in Chapter 7.
