Summary

Distillation has a low thermodynamic efficiency, requiring the input of high quality energy in the reboiler while rejecting a similar amount of heat at a lower temperature, in the condenser. Several heat pump concepts were proposed to upgrade that discharged energy and reduce the consumption of valuable utilities. This chapter explains the working principle and describes the most promising heat pump (HP) systems – such as VC, MVR, TVR, AHP, CRHP, TAHP, HIDiC – that can be used to upgrade the low quality energy from the condenser to drive the reboiler of a distillation column. Moreover, a practical selection scheme for binary and multicomponent separations is given, allowing process engineers to quickly and easily narrow down the most suitable energy efficient technologies applicable to distillation processes.
