METHOD OF DESIGN FOR PACKED COLUMN TYPE HIDiC

INTRODUCTION In Japan, Pilot Plant of the HIDiC was built in 2005. It was commercial base scale and already achieved the consecutive distillation for 1000 hours. The energy consumption of the pilot HIDiC was only about 70% of that of a conventional distillation column. The HIDiC can lower reboiler and condenser load by heat exchange between rectifying section and stripping section. Therefore, it was a distillation column of an energy saving model. In this study, we design to the HIDiC with structured packing, and examined separation performances used to experimental and simulation, and finally discussed the relationship between tower specification and design procedure.
