Design and Analysis of Divided Wall Column

In this study, an efficient design method has been proposed for determining the optimal design structure of the dividing wall column. Preliminary design parameters are fixed on the basis of well-known shortcut method (Fenske-Underwood-Gilliland). The rigorous optimization is used to obtain the optimal design parameters of the divided wall column. Divided wall column has total eight design variables, which affect the energy consumption. The optimal deign could save significant energy consumption in compare to the nominal design based on the shortcut method. The study has been also carried out to investigate the effect of energy supply on product compositions. It is the usual case in the real practice when the column is operated with the energy lower than the optimal energy required during operation.
