Summary

Heat-integrated distillation column (HIDiC) is the most radical approach of a heat pump design, making use of internal heat-integration: the rectifying section of a distillation column becomes the heat source, while the stripping part of the distillation column acts as a heat sink. Basically, the stripping section is physically separated from the rectifying section and the heat is transferred inside the distillation column – from the rectifying to the stripping section – due to the increased operating pressure of the rectifying section by means of a compressor. This chapter describes the working principle, potential energy savings based on a thermodynamic analysis, various design options (e.g., inter-coupled columns, concentric columns, shell & tube and plate-fin heat exchanger columns), issues related to the control and operation, as well as pilot-scale and industrial applications.
