“…Thus, one could reasonably expect that the increase of amine concentration may induce mass transfer limitations that hinder the extraction mechanism and delay reaching the thermodynamic equilibrium. Such a phenomenon was reported for succinic acid extracted with TOA from viscous aqueous solutions . In the present paper, viscosity measurements were performed for various mixtures of amines and n ‐decanol (Table ).…”

“…The interface must be disturbed mechanically to force the transfer of the acid‐amine complexes from the interface into the bulk of the extraction phase since acid molecules have a higher affinity towards water than the organic diluent. Stirring also increases the interfacial surface area and favors the extractant's accessibility to the interface …”

“…Such a phenomenon was reported for succinic acid extracted with TOA from viscous aqueous solutions. 26 In the present paper, viscosity measurements were performed for various mixtures of amines and n-decanol (Table 2). Results show a huge increase of viscosity for Aliquat 336 contents between 10 and 40%.…”

BACKGROUND: Bioconversion is a promising route to produce bio-based building blocks such as 3-hydroxypropionic acid (3-HP). Reactive extraction can be used for 3-HP recovery, and ultimately integrated to the bioconversion process. To the best of our knowledge, there is no published experimental data about the reactive extraction of 3-HP. This work aimed to study the extraction of 3-HP using tri-n-octylamine and Aliquat 336 as extractants in n-decanol. Comparison was also made with its positional isomer, lactic acid. Finally, the extraction of 3-HP from model and real bioconversion broths was examined.

We have performed two and three-dimensional phase field simulations using the lattice-Boltzmann method of liquid drops rising through a continuous phase liquid under the influence of buoyancy. In their upward motion the drops encounter a knife that is placed with the purpose of slicing the drops in two. A range of scenarios has been observed when the drop hits the knife and it has been investigated how the type of scenario depends on the dimensionless parameters governing the motion and slicing of the drop: the Eötvös number, the Morton number and the ratio of the droplet size and the width of the knife. We studied symmetric and asymmetric encounters between drop and knife and kept track of the size distribution of the resulting fragments.

These experiments were focused on the reactive extraction of succinic acid from Actinobacillus succinogenes suspensions with TOA dissolved in butyl acetate without and with 1-octanol. The results underlined the strong negative influence of cells on interfacial mass transfer rate, due to the physical barrier created at the interface by their adsorption. Thus, the mass flow recorded for the pure aqueous phase exceeded about 6.8−7.8 times that reached for aqueous suspension with a biomass concentration of 27 g L −1 d.w., this difference becoming more pronounced at higher pH-values of the aqueous phase. The negative influence of bacterial cells is attenuated by 1-octanol addition into the solvent phase. This effect was described by means of the amplification factor, which is over 1 for all discussed extraction systems containing 1-octanol. The influences of the extraction parameters and interfacial mechanism have been included in a mathematical model describing the acid mass flow from aqueous suspension to the organic phase, the average deviation from the experimental values being ±4.33%.
