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 varia...

Abstract Divided‐wall column (DWC) is an intensified separation process and so far developing a simple procedure for designing these units has been challenging. In this work, the concept of molecular tracking integrated with conventional methods to build easy‐to‐use methodology DWCs multicomponent separations. Application proposed approach highlighted through several three‐ four‐component mixtu...

This contribution aims to present a methodology to model and simulate the reactive dividing wall column (RDWC) using commercial software. Feasibility of separation scheme was established with ASPEN DISTILTM. Simulation of flowsheet configuration was performed with ASPEN HYSYSTM, using the two columns model. The reactive zone hosted by the prefractionator was modelled and simulated as backward f...

The paper presents the analysis of the thermal efficiency of a dividing wall distillation column and the influence of the feed composition on the reduction of energy consumption compared to a classical scheme of multicomponent mixture separation. The study relays on rigorous simulations in HYSYSTM using thermodynamically equivalent schemes. A case study is presented for the separation of a hydr...
