“…In practice, this means that the catalyst is allowed to leave the RD column in one of the product streams; or it is neutralized and separated as salt waste; or it is separated and recycled; or no catalyst separation or recovery is required. 4 A particular case of catalysis is the use of immobilized enzymes that allow new possibilities for the application of biocatalysts in organic synthesis, for example in the production of chiral compounds. Enzymatic Reactive Distillation (ERD) is a bio-reactive process, in which enzymes, immobilized on the internal surface of a column, help to overcome chemical reaction and phase equilibrium limitations.…”

“…Usually this leads to a restricted area in which RD is actually feasible, being a trade-off as shown in Figure 1. 4 However, this figure does not show the complete picture as there are also other parameters that play a role (e.g. : mass transfer, residence time, reaction rate) and can be altered by using different equipment of operating mode.…”

“…Nowadays, RD is considered an established industrial unit operation, being the front-runner in the PI field with more and more applications reported in literature. [1][2][3][4][5][6] RD relies on the synergy generated when combining catalyzed reactions and distillation into a single unit. But, as both operations take place in the same unit at the same time, there must be a good match between the operating parameters required for reaction and distillation.…”

Reactive distillation (RD) is an efficient process intensification technique that integrates chemical reaction and distillation in a single apparatus. The process is also known as catalytic distillation when a solid catalyst is used. RD technology has many key advantages such as reduced capital investment and significant energy savings, as it can surpass equilibrium limitations, simplify complex processes, increase product selectivity and improve separation efficiency. However, RD is also constrained by thermodynamic requirements (related to volatility differences and heat of reaction), the need to align the reaction and distillation operating conditions, and the availability of catalysts that are active, selective and with sufficient longevity. This paper is the first to provide an overview and insights into novel integrated reactive distillation technologies that combine RD principles with other intensified distillation technologies-e.g. dividing-wall column (DWC), cyclic distillation, HiGee distillation, heat-integrated distillation column (HIDiC), and membrane-, microwaveor ultrasound-assisted distillation-potentially leading to the development of new processes and applications.

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.
