“…To control the dividing wall column is the big challenge for the control engineers due to its high dynamics. Conventional controller like PID is not performed well in comparison to the advanced controller which was shown by the authors in their research [3]. Artificial neural network has been applied on dividing wall column for controlling the tray temperatures that is based on predictive technique.…”

Distillation is the most popular thermal separation technique used in the chemical and petrochemical process industry for the liquid mixture separation. Certainly, the distillation has a plenty of advantages, yet it has a drawback such as more energy requirement. In order to reduce the energy consumption of the conventional distillation column, energy integration is applied within the distillation column. The most important thermally coupled distillation column sequence is the Petlyuk column, which uses two recycle streams. Petlyuk column is a novel design that integrates two distillation columns into one shell, which is known as a dividing wall column. A dividing wall column (DWC) offers the possibility to separate a multicomponent mixture into high-purity products or sharp splits. Artificial neural network predictive controller (ANNPC) has been implemented to control the DWC. The performance of the ANNPC control strategies and the dynamic response of the DWC are investigated in terms of the product composition in the different sections of the dividing wall column for the different persistent disturbances such as feed flow rate, feed compositions, and liquid split factor.

“…Strategies have also been proposed to control DWC by measuring impurities in the product streams instead of the purities of the desired products 15. Recently, advanced control strategies for the control of thermally coupled systems have been proposed, such as model predictive control 16–18 and fuzzy control 19, among others. Also recently, Ramírez‐Corona et al 20 presented a control analysis of thermally coupled distillation columns, considering not only the isolated equipment but the interactions with whole processes.…”

The aviation sector is nowadays looking for a biofuel to partially substitute the fossil fuel used for flights, i.e., jet fuel. Among the proposed processes for the production of the renewable jet fuel, the hydrotreating process has, to date, the best performance. At the final stage of the hydrotreating process, a distillation train is required to obtain hydrocarbon fractions useful as fuels. Conventional or thermally coupled distillation sequences can be used in this step, and it can be expected that thermally coupled sequences require less energy to perform the separation. Nevertheless, in the selection of the best sequence for a given separation, it is important to analyze its control properties. A controllability analysis was performed here for different distillation sequences used to obtain biofuels from a hydrocarbon renewable mixture, in order to detect the best sequence in terms of control properties.

“…Reactive distillation is the combination of both separation and reaction in one unit [1][2][3][4]. It has been used in a small number of industrial applications for many years, but the last two decades has shown an increase in both research and applications.…”

“…It has been used in a small number of industrial applications for many years, but the last two decades has shown an increase in both research and applications. Distillation is the most desirable process for the separation of multi-component liquid mixture [4]. Combining reaction with distillation as is done in reactive distillation offers significant economic benefits, especially for reversible reactions.…”
