Process intensification in multicomponent distillation: A review of recent advancements

Global minimization of total exergy loss of multicomponent distillation configurations

“…This configuration has two reboilers at DE and E as well as two condensers at ABC and A , thereby allowing the heat duty to be generated and removed by heat exchangers operated at milder temperature levels. These observations demonstrate that, for most industrial applications, building the FTC configuration is not a reasonable first choice …”

Computer‐aided process intensification: Challenges, trends and opportunities

“…A number of recently published review/perspectives papers on PI, process synthesis, and reactive dividing wall columns have highlighted the tremendous potential of PI, and indicate a very high level of interest in PI because of the promise of significant improvements in the current state of the art in energy efficient operations as well as the possibility to discover truly innovative and novel solutions for new processing routes. They also confirm that the goals of smart manufacturing, sustainable production, circular economy could be realized through appropriate application of PI solutions.…”

“…Therefore, PI as a topic has been attracting much attention from industry as well as academia. Also, process systems engineering (PSE) has been closely related to the developments within PI as recent reviews on PI indicate. But what is PI, or, how can it be achieved?…”

“…For example, Baldea et al focused on modular manufacturing processes where PI has a role; Szydlowska et al highlighted the practical challenges associated with a class of chemical reactors; Stark proposed a rethinking of unit operations related to additive manufacturing; and, Jensen highlighted developments in microreaction technology. Also, this paper is not a review paper and readers interested in a review of PI are directed to the following recent review papers (to list a few): Tian et al gives an exhaustive overview on PI with 890 useful references related to PI; Sitter reviews PI related to PSE, Skiborowski reviews process synthesis and design related to PI, and, Jiang and Agrawal reviews PI related to multicomponent distillation. Hopefully, this perspective paper will provide answers to the following two questions: What is the need for PI, and, has the time for PI finally arrived?…”

Efficient generalized shortcut distillation model with improved accuracy for superstructure‐based process synthesis

“…However, adopting tray‐by‐tray based unit models for large distillation network superstructures can often lead to intractable optimization problems. Consequently, most superstructure‐based approaches 7,19,20 have employed the Underwood equations, 21,22 due to their reasonable accuracy and simplicity.…”
