A reduced‐order collocation method is applied to the optimal design of distillation columns. The resulting number of equations is determined by the user and is independent of the numbers of stages in the column sections. The collocation method furthermore permits these stage numbers to be treated as continuous variables, thus extending the discrete solution set. This greatly facilitates the optimization. Several demonstration problems are worked out.
