Abstract

The present work discusses a method for process intensification of the distillation process of separation. A model of an internally heat-integrated distillation column (HIDiC) of concentric type was developed using a rate-based model, and the separation of a binary mixture was simulated in a simulator which is capable of predicting steady-state conditions. The developed model was applied to a concentric-type HIDiC, and the heat transfer and operation performances were compared. This process improved the function and performance of conventional distillation separation process and could be miniaturized. In addition, the HIDiC showed highly energy saving performance compared with the conventional distillation processes.
