Research progress in reactive distillation

Advanced Separation Technology, 2023
As a special distillation process, reactive distillation technology has been widely used in the petrochemical field due to its outstanding advantages such as high efficiency and energy saving. It has been paid more and more attention from researchers in the field of chemical process enhancement since the 1920s.

Reactive Azeotropes in Kinetically Controlled Reactive Distillation

Chemical Engineering Research and Design, 1999
In this paper, a novel method for the determination of reactive azeotropes is presented that applies to chemical reactions that do not reach chemical equilibrium. The principles of the methodology are explained for ideal mixtures. For the MTBE- and TAME-synthesis the results obtained with this methodology are compared to the results from Thiel et al.

Modelling of reactive separation processes: reactive absorption and reactive distillation

Chemical Engineering and Processing: Process Intensification, 2003
In the last years chemical process industries have shown permanently increasing interest in the development of reactive separation processes (RSP) combining reaction and separation mechanisms into a single, integrated unit. Such processes bring several important advantages among which are increase of reaction yield and selectivity, overcoming ...

Reactive distillation of pyridine mixtures with an organic acid. I. Determination of the reactive distillation equilibrium

The Canadian Journal of Chemical Engineering, 1991
AbstractThe reactive distillation equilibrium has been experimentally determined by chromatographic analysis of the vapor phase for various mixtures of two pyridines plus an organic acid in stoichiometric deficiency in an organic solvent. Protonation of pyridines by a weak acid seems to involve ion pair formation, while protonation by a strong acid ...

Reactive distillation with KATAPAK®

Catalysis Today, 2001
Abstract KATAPAK-SP and -S are structured catalytic packings for reactive distillation or gas–liquid reactors available from laboratory to industrial scale. Applying the KATAPAK-SP concept, the ratio of catalyst volume fraction to separation efficiency can be varied over a wide range, therefore the design of a reactive distillation column can be ...

Reactive Distillation Technology

2014
Reactive distillation (RD) processes integrate reaction and distillation, the reactants being converted with the simultaneous separation of the products. This chapter describes the use of reactive distillation technology to produce biodiesel by esterification of free fatty acids, or trans-esterification of various oils (triglycerides).

Circumventing an Azeotrope in Reactive Distillation

Industrial & Engineering Chemistry Research, 2000
Using a McCabe−Thiele diagram, we explain nonintuitive behavior in a binary reactive distillation column where we react and separate two isomers displaying a maximum boiling azeotrope. Placing sufficient reaction on only two trays in the top section of the column, we shift the top operating line to lie below the 45° line. On lower nonreacting trays, we

Reactive Distillation and Kinetic Azeotropy

Industrial & Engineering Chemistry Research, 1994
The general pattern of trajectories of equilibrium distillation with nonequilibrium reversible reaction in the liquid phase is discussed. In some cases there is a continuous line of singular points belonging to different ratios of the evaporation rate and the reaction rate. These points are the kinetic azeotropes.

Enzymatic Reactive Absorption and Distillation

2018
In this work, innovative concepts for reactive separation processes, such as reactive absorption and distillation, that make use of bio-based catalysts, in specific enzymes, are discussed. Enzymatic Reactive Absorption (ERA) and Distillation (ERD) offer potential for energy and investment savings or improved selectivity by exploiting enzyme merits like
