“…And there is also an evident decreasing tendency shown in distribution coefficients and separation factors with the increasing of cresol's concentration in the aqueous phase or in the organic phase at a certain temperature, indicating that concentration also put a vital effect on the distribution ratios of cresol among organic phase and aqueous phase and on the separation factors. Such temperature and concentration dependence could also be commonly observed in many other ternary systems, especially phenols containing systems [34][35][36][37][38][39]. It can also be seen from figures 7 and 8 that, the influence of the structure of cresol isomers on the extractive properties of 2-pentanone is insignificant, as the distribution coefficients and separation factors are very close for the three cresol isomers when using 2-pentanone as the extraction agent.…”

The (liquid + liquid) equilibrium (LLE) data are vital for the liquid extraction of cresols from aqueous solution with 2-pentanone as an extraction agent. Therefore, the ternary LLE data for {2-pentanone + o-cresol, m-cresol or p-cresol + water} were determined at T = (298.15 and 323.15) K and p = 101.3 kPa. And the reliability of the LLE data was ascertained by using the Othmer-Tobias and Hand equations. The distribution coefficients and separation factors were calculated to evaluate the effectiveness of extracting cresols from water. The thermodynamic NRTL and UNIQUAC models were used to correlate the experimental LLE data of the studied systems, and the binary interaction parameter values were obtained from the data correlation.

“…Considering the advantages of a single solvent and the drawbacks of salt raised in “ Background ”, this work only considers single solvents for extracting 2,3-BDO from the fermentation broth. Thus, the LLE data of mixed solvents with salt [ 39 , 40 ] or other components [ 42 , 65 ] were excluded. Table 2 compares several solvents that have LLE data at approximately 25 °C (the real fermentation broth temperature that will be used in the design).…”

Background2,3-Butanediol (2,3-BDO) is a synthetic chemical compound that also can be produced by biomass fermentation, which is gaining share in the global market as an intermediate product for numerous applications, i.e. as liquid fuel or fuel additive. Several metabolic engineering fermentation strategies to enhance the production of 2,3-BDO were developed. However, the recovery of 2,3-BDO from its fermentation broth remains a challenge due to its low concentration and its solubility in water and other components. Thus, a cost-effective recovery process is required to deliver the required purity of 2,3-BDO. This paper presents a new process development and techno-economic analysis for 2,3-BDO purification from a fermentation broth.ResultsConventional distillation and hybrid extraction-distillation (HED) processes are proposed in this study with detailed optimization and economic analysis. Particularly, a systematic solvent selection method was successfully implemented to determine a good solvent for the proposed HED configuration based on numerous experimental data obtained with each solvent candidate. NRTL and UNIQUAC property methods were evaluated to obtain binary interaction parameters of 2,3-BDO through rigorous Aspen Plus regression and validated using experimental data. Total annual cost (TAC)-based optimization was performed for each proposed configuration. Even though the HED configuration required 9.5% higher capital cost than conventional distillation, placing an extraction column before the distillation column was effective in removing water from the fermentation broth and significantly improved the overall process economics.ConclusionsOleyl alcohol was found to be the most suitable solvent for the HED of 2,3-BDO due to its high distribution coefficient and high selectivity. The proposed HED drastically reduced reboiler duty consumption and TAC by up to 54.8 and 25.8%, respectively. The proposed design is expected to be used for the commercial scale of 2,3-BDO production from fermentation process.Electronic supplementary materialThe online version of this article (10.1186/s13068-018-1013-3) contains supplementary material, which is available to authorized users.

“…Among different separation schemes studied, the use of solvents for extraction (solvent extraction or liquid–liquid extraction) of 2,3‐butanediol seems most promising owing to the ease of operation and lower energy requirements. For the extraction of 2,3‐butanediol, various organic solvents and ionic liquids have been explored and their liquid–liquid equilibrium data is reported in the literature . The use of solvents alone, however, is not sufficient as it provides a low distribution of 2,3‐butanediol.…”

BACKGROUND: Solvent extraction of 2,3-butanediol from dilute fermented systems is a challenging downstream unit operation. Addition of certain kosmotropic salts to the aqueous fermentation broth during the solvent extraction process can have considerable influence on the distribution of 2,3-butanediol. This work evaluates the usefulness of solvent extraction and the salting-out effect on the extraction characteristic of 2,3-butanediol in aqueous synthetic and fermented solutions.
