A graphical method for the preliminary design of ternary simple distillation columns at finite reflux
The present study proposes a graphical method for the design of ternary distillation systems at finite reflux. Here key design parameters are determined, in particular feed stage location and the number of theoretical stages required for separation at finite reflux for ideal and nonideal systems in...

| description | The present study proposes a graphical method for the design of ternary distillation systems at finite reflux. Here key design parameters are determined, in particular feed stage location and the number of theoretical stages required for separation at finite reflux for ideal and nonideal systems in simple columns. The procedure provides designers with a visual tool to determine the design parameters simultaneously and no additional calculations are required unlike current approaches. The proposed graphical method correlated to the Fenske-Underwood-Gilliland (FUG) method for ideal systems. The parameters obtained from the proposed graphical allow for implementation in rigorous simulators as starting values to achieve a converged column with the first simulation and less computational difficulty. |
