The proposed of the present work is to develop a modeling and process design of the HIDiC. The model of HIDiC with structured packing is developed by rate-based model using Maxwell-Stefan equations. In this study, we have developed the HIDiC models by the process simulator “gPROMS”. Comparison of observed data from bench-scale (benzene-toluene system) separation concentric HIDiC plant, in which consisted of about 20 m in height and 254 mm in diameter. Predicted simulation results show a good agreement with observed data. The bench HIDiC showed about 40 % reduction of energy consumption than the conventional distillation column. The effect of process design in the HIDiC is also discussed.
