Recent advances in the internally heat-integrated distillation columns (HIDiC)

Distillation is the most widely used but the most energy-consuming separation process in the chemical industry. The internally Heat-Integrated Distillation Columns (HIDiC) are one of the promising alternatives of the conventional distillation processes to reduce the energy consumptions in chemical processes. The HIDiC has a similar structure to a heat exchanger. The rectifying section is contac...

Basic design of a double-pipe unit type internally heat integrated distillation column (HIDiC)

Distillation is not only the most energy consumer but also the most frequently-adopted separation operation in chemical industries since it separates a mixture only by the difference among vapor pressures (boiling points) of components. So distillation is often called as the king of separation processes. Therefore, research and development of technologies on energy savings of distillation is an...

A thermo-hydraulic approach to conceptual design of an internally heat-integrated distillation column (i-HIDiC)

This paper presents a new approach to the conceptual design of internally heatintegrated distillation columns (i-HIDiC), based on column temperature profiles analysis. The paper proposes tools to assess the thermal feasibility of i-HIDiC designs and to determine whether the design and operation are feasible from the hydraulics’ point of view.
