A novel simplified configuration for an ideal heat-integrated distillation column (ideal HIDiC)

Nonlinear wave modeling and dynamic analysis of high-purity heat integrated air separation column

“…(8) and (9), the instant wave velocities of two sections: Eqs. (14) and (15), and some other basic relations in our previous work (Eqs.…”

“…The heat integrated distillation column (HIDiC) has long been regarded as a promising energy-saving technique since first conceptually introduced by Mah and co-workers [7]. Many researchers carried on analytical research on HIDiC and gained much success [8][9][10][11][12][13][14][15][16]. Then a lot of national projects have applied this technology to the air separation and proved that the heat integrated air separation column (HIASC) could save more energy than the conventional air separation column (CASC) [17][18][19][20][21][22].…”

Evaluation of a novel configuration of bottom flashing on dual distillation columns for saving energy

“…Various configurations of these systems have been presented in previous studies [7,8,18,[20][21][22][23][24][25]. These configurations include: vapor recompression with intermediate reboiler(s) [20,26,27], vapor recompression with self-heat recuperation [28], vapor recompression with extra heat transfer units [7], vapor recompression and bottom flashing on petlyuk column [8], simplified heat integrated distillation column [25], heat integrated distillation with additional heat transfer between top product and feed [12] and heat integrated distillation columns for separating ternary mixtures [14].…”

Current trends of using process intensification principles, along various optimization techniques for simultaneous control and design for improving performance of distillation systems were studied in a recent paper [29].…”

Nonlinear dynamic behaviors and control based on simulation of high-purity heat integrated air separation column

“…However, some characteristics of HIDiC, such as high nonlinearity, asymmetry and interaction, bring many difficulties to optimization and controller design, especially for high-purity columns. These characteristics draw many researchers attention and some Contents lists available at ScienceDirect journal homepage: www.elsevier.com/locate/isatrans research works were carried out [26][27][28][29][30][31][32]. Suphanit investigated the optimization of heat distribution in HIDiC through the application of flow sheet modeling and optimization solver in Aspen Plus [33].…”
