Welcome to Chemical Engineering Progress
Distillation modeling is typically performed via the equilibrium-stage model. However, this model does not reflect the true conditions of an actual distillation column. With today's increased computing power, simulations based on complex nonequilibrium, or rate-based, models are feasible, and in some cases they should be regarded as mandatory (pp.28-39). Also, look for the special "Women in Engineering" supplement coming in August.

Real World Modeling of Distillation
Previously, simulations based on nonequilibrium, or rate-based, models were considered impractical due to their complexity. However, with ever-increasing computing power, these simulations are not only feasible, but in some circumstances they should be regarded as mandatory.
