“…Kumar and Daoutidis [24] studied the control of an ethylene glycol reactive distillation column and concluded that an advanced nonlinear inverse-based controller is needed Monroy-Loperens [25] also studied the control of ethylene glycol reactive distillation column. They controlled the ethylene glycol composition in the product by manipulating the reboiler boil-up ratio.…”

“…The separation often gets simplified via ''reacting away'' of azeotropes [2]. RD has thus been successfully implemented as a promising commercial alternative to the conventional schemes of ''reaction followed by separation'' for a large variety of reaction chemistries such as etherification [3][4][5], esterification [6,7] and hydration [8,9].…”

Decentralized control system design is evaluated for a basic and an internally heat-integrated generic, ideal, double-feed, two-product reactive distillation system. The internally heat-integrated reactive distillation column (HiRDC) is obtained via catalyst redistribution into the rectifying zone and feed tray relocation. For basic regulatory control, three two-point control structures with a fixed reflux rate or a fixed reflux ratio operation policy are synthesized and evaluated for their closed-loop disturbance rejection characteristics using rigorous dynamic simulations. To eliminate the purity offsets for on-target product purities, product purity composition controllers manipulating the reflux ratio and stripping tray temperature set point are implemented. Reactive tray section composition control is necessary for on-target product purity operation of HiRDC.

“…For the control of a continuously operated reactive distillation column, Baldon, Strifezza, Basualdo, and Ruiz (1997) used a linear Dynamic Matrix Control (DMC) algorithm, while Doyle and Balasubramhanya (2000) employed the concept of travelling waves to generate reduced-order nonlinear process models which are used in a nonlinear MPC-scheme. Kumar and Daoutidis (1999) proposed a nonlinear input/output linearising controller, and Gru¨ner et al (2003) derived a nonlinear controller by combining input/output linearisation with the design of an observer. For the control of a batch column, MonroyLoperena and Alvarez-Ramirez (2000) proposed a nonlinear PID-type controller.…”
