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

A laboratory distillation column is to be set up to evaluate overall column efficiencies at finite reflux. The choice of the number of plates in each section of the column will profoundly affect the accuracy of the final results. That number of plates which minimises the errors is optimal. A genera
In this paper we describe plateby-plate calculations of separation columns using finite difference equations. The calculations were performed on the WEIZAC digital computer. The purpose of the calculations was essentially twofold: (a) comparison of various ideal cascades among themselves and with co
