“…The results showed that the energy savings predicted in the complex extractive distillation sequence can be achieved with reductions in greenhouse gas emissions, higher thermodynamic efficiencies and lower minimum total annual operating cost. This study is the continuation of the work of Gutiérrez-Guerra et al (2009). We analyze the dynamic behavior of the cases of study designed in the aforementioned paper and compare them to extractive conventional distillation arrangements.…”

In particular, the presence of recycle streams for coupled schemes has led to the notion that control problems might be expected during the operation of these systems, in contrast to the rather well-known behavior of conventional distillation sequences.In this work, we analyze the control properties of thermally coupled extractive distillation schemes studied previously (Gutiérrez-Guerra, R., Segovia-Hernández, J.G. and a closed-loop analysis. The results showed that the energy savings predicted in the complex extractive distillation sequence can be achieved along with good dynamic behavior and reductions in greenhouse gas emissions.

“…1.3.2 Azeotropic distillation The term azeotropic distillation applies to a class of distillation techniques characterized by fractional separation based on the azeotropic properties of the system. The agent responsible for the specific azeotropic behavior, which is known as an entrainer, can either be present in the feed mixture (self-entraining process) or can be added to the process to separate the mass (Widagdo and Seider, 1996;Doherty and Malone, 2001;Guedes et al, 2007;Gutiérrez-Guerra et al, 2009;Ibarra-Sánchez and Segovia-Hernández, 2010). To make the separation feasible, two important characteristics of this additional azeotrope are important.…”

“…Extractive distillation (Figure 12) is used widely in many processes (Arifin and Chien, 2008;Gil et al, 2008;Hernán-dez, 2008;Gil et al, 2009;Gutiérrez-Guerra et al, 2009), but its high energy consumption is a major disadvantage that should be overcome. To reduce the energy requirements, TCDS can be utilized through the implementation of interconnecting streams to achieve thermally coupled extractive distillation sequences (TCEDS-SR) (Gutiérrez-Guerra et al, 2009;Ibarra-Sánchez and Segovia-Hernández, 2010).…”

Distillation is a common energy-intensive process. Accordingly, it is the rst process to be addressed to improve the energy e ciency over both the short-and long-term. Recent studies and industrial applications have proven that advanced process integration and process intensi cation techniques such as the use of a thermally coupled distillation sequence (TCDS) and a dividing wall column (DWC) require the lowest amount of energy for the separation of mixtures into pure product streams. This paper reviews some energy-e cient distillation technologies that can be used in a retro t design. The research on and implementation of retro ts using a TCDS and DWC are reviewed. This report proposes coupled schemes as alternatives to using a Petlyuk column that do not have the classical problem of controlling the vapor transfer from one column to another and have not previously been proposed for retro ts. These schemes are expected to make signi cant contributions to improving the energy e ciency and mitigating CO 2 emission in the retro tting of distillation systems. The authors evaluated a solution for retro tting azeotropic and extractive distillation systems. Various issues such as the constraints, techno-economic analysis, controllability, and operability are discussed brie y to provide more insight into the application of TCDS and DWC technologies in the retro t.

“…Extractive distillation is widely used in numerous processes, but it consumes high amount of energy, which requires dispatching [6], [9]- [14]. Process integration is an attracting choice for handling this issue and it has been successful in decreasing the energy requirements in comparison with sequences where all the units are configured with little or no integration [8].…”

Abstract-This paper proposed a novel integrated design of azeotropic mixtures distillation process based on mechanical vapor recompression (MVR). The extractive distillation of acetone -methanol binary system that forms a homogeneous minimum -boiling azeotrope was studied. Based on the simulation result, the total energy consumption of the proposed sequence is 62% less than the existing extractive distillation configuration.Index Terms-Mechanical vapor recompression, MVR, heat integration, azeotropic distillation, extractive distillation.
