A nonequilibrium (mass-transfer-rate-based) model has been used to determine the minimum reflux ratio and the minimum number of stages in distillation. It was found that, for a column with an infinite number of stages, R(min) calculated from the rate-based approach was the same as that computed using an equilibrium model. A substantial difference in the R(min) calculated using the different methods was observed for a column with a specified number of stages.
