6.8 Summary—Objectives

In this chapter we have developed methods for multicomponent distillation. The objectives for this chapter are as follows:

1. Use a matrix approach to solve the multicomponent mass balances

2. Use bubble-point calculations to determine new temperatures on each stage

3. Use a matrix approach to solve the energy balances for new flow rates.

4. Explain the difference between the bubble-point and Naphtali-Sandholm methods
