“…In the recent years, several groups are actively involved in research on energy-efficient distillation column design (e.g., [29][30][31]), analysis (e.g., [32,33]) and operations (e.g., [31,34]). Since 1990, several heat integrated distillation structures have also been patented [35][36][37][38][39][40][41].…”

“…Especially when the compression ratio of the HIDiC is maintained at a constant value and the purity of the bottom product is high, multiple steady-states appear in a wide range of operating conditions, suggesting that the operation and the control strategies for the HIDiC should be di erent from those for the CDiCs. Huang et al have been studying the dynamic behavior of HIDiCs (Huang et al, , 2006b(Huang et al, , 2006c(Huang et al, , 2006d(Huang et al, , 2006e, 2006f, 2006g, 2007a(Huang et al, , 2007b. Recently, they reported a new temperature control scheme for HIDiCs (Huang et al, 2008).…”

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.

“…29 In that study it was shown that the intensified HIDiC is the most energy-efficient configuration. Nevertheless, through a closed loop controllability study 30 it was found that to split ternary mixtures, the intensified HIDiC presented properties that were worse than those of the ideal HIDiC (iHIDiC) and the general HIDiC. In another study, 31 the thermodynamic feasibility of integrating energy under the pinch point concept was analyzed.…”

ABSTRACT:The technology of the heat-integrated distillation column (HIDiC) has shown to be a potential energy-saving alternative for separating close-boiling mixtures. However, the economic aspects are a critical factor to extensive use of this distillation sequence in real applications. In this research, a novel stochastic optimization algorithm called Boltzmann univariate marginal distribution algorithm (BUMDA) with constraints handling has been implemented to optimize HIDiC sequences. Three binary mixtures were examined: butanol−isobutanol, n-heptane−cyclohexane, and benzene−toluene. The evaluation was performed by applying a new robust methodology using the interface Matlab−Excel−Aspen Plus. The model Radfrac was used in the simulations in Aspen Plus. The minimization of the total annual cost was established as the fitness function of the problem. Results showed the great robustness presented by the BUMDA algorithm for solving successfully this kind of complex optimization problem. Thus, the HIDiC design to separate the alcohol mixture showed energy savings of 84% and a cost that was lower (2%) than that of the conventional column. In addition, the hydrocarbon mixtures reached energy savings of 62.5% (nheptane−cyclohexane) and 52.5% (benzene−toluene). Nevertheless, the total annual cost (TAC) of the HIDiC is larger than the TAC of the conventional column (32% and 35%, respectively).
