“…e payback time of the HIDiC for a PP splitter is only 9 months, whereas that of the CDiC is about 20 months. A new conceptual design method of HIDiCs with heat panels was introduced based on the stage temperature pro les and hydraulic calculations (Gadella et al, 2005b(Gadella et al, 2007Olujic et al, 2006;Schmal et al, 2006). A variable heat transfer rate design leads to better designs with minimum total cost compared to constant heat transfer rate schemes.…”

Internally heat integrated distillation columns (HIDiCs) have attracted industrial attention since HIDiCs are expected to have a strong impact on energy savings in chemical industries. Particularly in Japan, large national research projects for HIDiCs have been conducted, and a HIDiC pilot plant has been constructed. The pilot HIDiC has shown energy savings of more than 60% compared to a conventional distillation column in the separation example of a twelve-component hydrocarbon mixture. In addition, several research projects on HIDiCs have been carried out also in Europe. In this paper, the overview and recent advances in HIDiC technologies of Japan and Europe are introduced.

“…Strong loop interactions have been reported. Schmal et al (2006) studied the operation of a HIDiC splitting a propylene/propane mixture, and indicated that a model predictive control (MPC) based scheme would have improved their operational results due to interactions between loops. Recently, Bisgaard et al (2017) studied optimal operation of the HIDiC for two case studies where benzene/toluene and a multicomponent aromatic mixture was separated.…”

“…Other two popular schemes are based on internal energy integration (e.g., internally heat integrated distillation column (HIDiC)) and external energy integration (e.g., direct vapor recompression column (VRC)) . By performing operational and economic analysis, a systematic comparison between the HIDiC and VRC is presented in the literature . In particular, the heat pump system has been emerging as an important scheme, because it is easy to introduce and the plant operation is usually simpler compared to other heat integration strategies .…”

In this contribution, the direct vapor recompression approach is introduced in a batch distillation operated at an unsteady state condition. This vapor recompressed batch distillation (VRBD) accompanies an isentropic compressor that runs at a fixed as well as variable speed. Aiming to ensure the optimal use of internal heat source, an open-loop control policy is proposed for the VRBD that adjusts either the overhead vapor splitting or the external heat supply to the reboiler. Again, the variable speed VRBD additionally involves the manipulation of compression ratio. Developing two alternative configurations of VRBD column, the best heat integrated scheme is attempted to identify in the aspects of energy efficiency and total annualized cost for further advancement. A closed-loop control algorithm for the best performing variable speed VRBD aiming to meet the end objective of relatively high-purity product discharged at a constant composition is developed. The separation of a reactive system is considered to illustrate these results and demonstrate the effectiveness of the novel VRBD scheme. Performing simulation tests, it is investigated that the closedloop control operation substantially improves not only the distillate purity but also the total amount of product. Achieving significant improvement in thermodynamic efficiency and cost by the controlled heat integrated scheme over its conventional counterpart, finally the attractiveness of the VRBD column by investigating its potential to reduce the greenhouse gas (i.e., CO 2 ) emissions is shown. a It is same for both open-loop and closed-loop CRBD, because in both cases, the operating hours/year, external heat input to the still (i.e., Q R ) and temperature at which the steam is delivered are identical.
