Semicontinuous reactive extraction and reactive distillation

Chemical Engineering Research and Design, 2009
A novel semicontinuous process that alternates between reactive extraction and reactive distillation in a single packed column is introduced. It is illustrated for the recovery of dilute 1,3-propanediol from an aqueous fermentation broth. 1,3-Propanediol is recovered by reaction with isobutyraldehyde, forming 2-isopropyl-1,3-dioxane.

Reactive extraction of pyruvic acid using mixed extractants

Separation Science and Technology, 2016
ABSTRACTThe synergistic effect of mixing of extractants (tri-n-butylphosphate, TBP; tri-n-octylamine, TOA; and Aliquat 336, A336) was investigated in view of recovery of pyruvic acid from fermentation media. Extraction experiments were performed at T = 302K, from aqueous solution of pyruvic acid (0.025–0.2 kmol m−3) using single and mixed extractants ...

Reactive Extraction of Levulinic Acid by Amberlite LA-2 Extractant

Journal of Chemical & Engineering Data, 2009
The production of organic acids at relatively low concentrations in aqueous solutions is typical of both electrochemical and biochemical syntheses. The recovery of these solute species can be achieved by solvent extraction, and the reactive recovery of carboxylic acids from aqueous solutions has received increasing attention. In this study the reactive

Exergy analysis of a reactive extraction process

Chemical Engineering Research and Design, 2020
Abstract This work proposes a methodology to perform exergy analysis of an intensified isothermal reactive extraction process. The method involves two steps. The first one includes the modeling and adaptation of a material utilization diagram (MUD) to allow the estimation of exergy losses and gains for each component and for the overall process.

REACTIVE EXTRACTION OF ORGANIC ACIDS BY SUPERCRITICAL CO2

Reviews in Chemical Engineering, 1999
Reactive extraction of citric acid and acetic acid from their aqueous solutions by supercritical (SC) CO2 was studied. Since organic acids are polar compounds which can hardly be extracted by SC CO2, reactants which increase the solubility of the acid by a chemical reaction are used.

Reactive Extraction Technology

2014
Reactive extraction is a process intensification alternative for conventional biodiesel processes, which effectively combines the extraction of oils using a solvent, with the (trans-) esterification reaction yielding fatty esters (biodiesel). This chapter gives an ample overview of using reactive extraction for biodiesel production—where typically the ...
