paper proposed a shortcut method for the structure design of dividing wall column based on the Fen-ske-Underwood equation by applying it on thre conventional simple column configuration. It is shown that the pro-posed shortcut method can design the column structure including the feed tray, dividing wall section, and side-streamtray in a simple and efficient way in the initial design stage. Simulation study using HYSYS to compare the energy sav-ing performance betwen the conventional sequential two column system and the dividing wal column designed by theproposed method shows that the proposed dividing wal column system saves from 16. to 65. more over the con-depends on the composition of intermediate component while the optimal energy consumption patern to internal flowdistribution on the dividing wal section is characterized by the ESI factor of the feed mixture.
