“…Among the different studies illustrated in Figure 2, the application of RED for ternary azeotropic separation was first initiated by the Shen's research group in 2020 where they employed the TCRED (Figure 1A) for the separation of THF/ ethanol/water (Su et al, 2020;Yang et al, 2020). In comparison to the pressure-swing distillation, the RED reduces the total annual cost (TAC) and CO 2 emission by 63 and 84%, respectively.…”

“…Other than extending the application of RED to other ternary azeotropic mixture, another recommendation given by Shen's group (Su et al, 2020;Yang et al, 2020) was to explore on the integration of PI techniques such as thermally coupled, dividing wall, side-stream, and vapourrecompression to the RED for further energy saving. Following this, the same group took the initiative to analyse the benefits of integrating the dividing wall to the DCRED to become a dividing wall reactive-extractive distillation (DW-RED) for the separation of TBA/ethanol/ water (Yang et al, 2022b).…”

“…Upon meticulous analysis on the trend for existing studies, it becomes apparent that all the existing studies today are Frontiers in Chemical Engineering frontiersin.org moving towards sustainable separation by means of reducing the energy, environmental, and economic impacts through combination of different PI techniques such the DCRED (i.e. combination between reaction and separation in one column) (Su et al, 2020;Wang et al, 2021;Zhang et al, 2021), DW-RED (i.e. combination of DCRED with dividing wall) (Yang et al, 2022b;Liu et al, 2022;Yan et al, 2022), and integrating side-stream extractive distillation with VRHP (Yang et al, 2022a).…”

The reactive-extractive distillation (RED) has the advantages of combining the beneficial features of both reaction and separation processes. Relative to the conventional reactive or extractive distillation-based processes, the RED is also less energy intensive as it relies on the reaction heat produced for the subsequent separation process. Therefore, the application of RED for ternary azeotropic separation has become the subject of popular interest, as evident by the increasing number of publications since 2020. This review paper is the first that puts together, in a chronological manner, all the existing studies on the RED to date, starting from the initial three column reactive-extractive distillation (TCRED) to the most recent dividing wall reactive-extractive distillation (DW-RED), for ternary azeotropic separation, so that the rapid progress in this area is summarised and any existing gaps in these studies become easier to identify for future work. The last part of this review provides three potential areas for future work, i.e. analysis of the sustainability of RED, combination of different process intensification strategies to improve the energy efficiency and separation performance, and further exploration on the control studies for the RED.

“…Recently, SA was also used for the optimization of ED sequences with side streams [79]. GA has been used for the optimization of an RD and ED sequence using a multi-objective optimization framework considering economic and environmental criteria [80], and in RD and pressure-swing distillation (PSD) [81]. In these works, the reported TAC using SA or GA was lower than that obtained using the SI approach.…”

Process Intensification (PI) is a vast and growing area in Chemical Engineering, which deals with the enhancement of current technology to enable improved efficiency; energy, cost, and environmental impact reduction; small size; and better integration with the other equipment. Since process intensification results in novel, but complex, systems, it is necessary to rely on optimization and control techniques that can cope with such new processes. Therefore, this review presents some advancements in the field of process intensification that are worthy of exploring in detail in the coming years. At the end, several important open questions that can be taken into consideration in the coming years are listed.

“…The results showed that the exergy efficiency of demethanizer and dealkylation section is the lowest. Environmental analysis 30,31 is also an extraordinary important indicator in the development of the chemical industry. The environmental feasibility analysis of the chemical production process is of great significance to realize clean, lowenergy, and sustainable production.…”

The traditional production of butyl acetate (BA) has the problems of low equilibrium conversion rate and high energy consumption of product separation and purification. In this work, the production processes of BA by transesterification and esterification were simulated. Taking the annual total cost as the objective function, the process parameters of the two processes were optimized by the sequential iterative optimization method. The analysis showed that the total annual costs (TACs) of the two processes with an annual output of 3.46 × 104 t of the product are 4.45 × 106 $/year and 1.75 × 106 $/year, respectively. Compared with the esterification process, the transesterification process has a higher economic performance. Under the optimal economic conditions, the nondominated sorting genetic algorithm II (NSGA-II) technology is used to optimize the total exergy loss and carbon emission. When the exergy loss rate is the lowest (exergy loss rate = 68.52%), the carbon emission is 1210.8286 kg/h. When the carbon emission is the lowest (carbon emission = 1210.8221 kg/h), the exergy loss rate is 68.53% accordingly. The comprehensive analysis and optimization results provide theoretical guidance for the green and sustainable development of the BA production.
