H1. Generation of distillation curves for systems with constant relative volatility is fairly straightforward and is an excellent learning experience. Generate distillation curves in Figure 8-7 for the benzene (A), toluene (B), cumene (C) system with αAB = 2.4, αBB = 1.0 and αCB = 0.21. Operation is at total reflux.
a. Mole fraction of A in the reboiler is 0.006735 and mole fraction of B is 0.003469.*
b. Mole fraction of A in the reboiler is 0.001 and mole fraction of B is 0.009.*
c. Mole fraction of A in the reboiler is 0.0003 and mole fraction of B is 0.0097.
Remember the sum of the mole fractions of A, B, and C in the reboiler is 1.0. *Solution is shown in Figure 8-7.
