“…For all case studies, the components were considered of equal density (900 kg/m 3 ), equal molecular weight (50 g/mol) and equal boiling point of the heavy reactant, component B (413 K). This boiling point was assumed to be fixed and all other volatilities were calculated using the heavy reactant as the reference (Tsatse et al 2021) in order to create the desired relative volatilities. Note that for Case study 3, although the VLE parameters are different compared to Case study 1 and Case study 2, the relative volatility between the products (αCD) is the same, and equal to 6.…”

“…In a previous contribution, we discussed how the steady state design and operation of a complex reactive distillation superstructure, which also included additional pre-/side-equipment, can be simultaneously optimised to meet the given product quality constraints (Tsatse et al 2021). In this paper, the dynamic performance and controllability of a reactive distillation process is evaluated using a proposed methodology, in order to obtain insight into the impact of various system characteristics on the controllability of the process.…”

“…In this paper, the dynamic performance and controllability of a reactive distillation process is evaluated using a proposed methodology, in order to obtain insight into the impact of various system characteristics on the controllability of the process. This work focusses on several cases for which the optimal steady state configuration was determined in our previous work (Tsatse et al 2021). Authors who have discussed the controllability of reactive distillation systems have generally only considered the dynamic behaviour and control of specific chemical systems and reactive distillation designs by implementing various control strategies, conventional or advanced, to indicate which technique is the most effective in their specific case.…”

Optimal design of reduced vapor transfer dividing wall structures with and without heat integration

A dividing wall column (DWC) is a prime example of process intensification, whereby significant energy and cost savings can be achieved for some systems compared to operation in conventional design of two columns in series. It has been theorized that the vapor and liquid thermal coupling streams in the DWC could be replaced by liquid‐only transfer streams, making the DWC unit less complex. The ultimate structure is the liquid‐liquid (LL) structure with all thermal coupling streams replaced and a dividing wall extending from the top to the bottom. This article compares the separation and economic performances of the regular DWC and the LL structure, and further investigates the benefits of heat‐integrated alternatives of both (combined condenser and reboiler, double‐effect, vapor recompression assisted). Optimization uncovered that vapor recompression assisted structures exhibit substantial energy savings and lowered total annualized cost but that the savings depend on electricity and utility costs.

Reactive distillation (RD) is a process intensification technique that offers major advantages over conventional technologies by enabling the integration of reaction and separation into a single apparatus. This integration introduces and exploits complex interaction between mass transfer, chemical reaction and hydrodynamics within an RD column; however, these complexities can hinder the adoption of reactive distillation by industry.Many approaches were developed by the scientific community to advance understanding and to expedite the initialization of RD design at the conceptual level. This paper critically discusses recent developments in conceptual methods for synthesizing RD processes. This review paper is the first to consider the range of available approaches for assessing the technical feasibility, controllability, economic viability, and sustainability, of RD units by taking into account various configurations in which RD is treated as a new unit operation, and as part of process synthesis in a different way of designing processes based on functions. The review also addresses complex configurations, such as advanced RD technologies. Special attention is paid to process modeling and simulation as well as to education. Knowledge gaps to be filled by further research are indicated.This article is protected by copyright. All rights reserved.
