(211c) Process Intensification For The Distillation With Heat-Integration

The proposed of the present work is to discuss a method for ?Process Intensification? of the distillation process of separation. The model of an internally heat-integrated distillation column (HIDiC) with concentric type and compact heat exchanger type were developed by a rate-based model and the separation of multicomponent mixture was simulated. This has been implemented in the simulator which is capable of predicting dynamic conditions. The developed model has been used as concentric and compact heat exchanger types for HIDiC, and their separation and operation performance was discussed. In the results, The HIDiC compact heat exchanger process can be also obtained for zero reflux and/or no reboil operation. This process improved the function and performance of conventional distillation separation process and could make it a miniature. In addition, the HIDiC compact heat exchanger showed highly energy saving performance compared with the conventional distillation processes.
