The extension of the translated–consistent Peng–Robinson (tc-PR) equation state (EoS) to mixtures has been investigated. For this purpose, advanced EoS/aresE,γ mixing rules are used combine tc-PR EoS with residual part an activity coefficient model chosen among Wilson, nonrandom two-liquid (NRTL), and universal quasi-chemical (UNIQUAC) models. performances three resulting versions compared agai...

Background 2,3-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 f...

The composition dependence of the surface tension of highly nonideal organic-organic and aqueous-organic nonelectrolyte solutions is described, based on the assumption that the surface layer can be treated as a separate phase located between vapor and bulk liquid phases. The Wilson, NRTL, and UNIFAC methods are used for activity coefficients of surface and bulk phases and three techniques for c...

Electrolyte thermodynamics is a complex and broad subject of immense importance in very diverse applications. The models proposed for electrolyte solutions have some similarities to those non-electrolytes but also significant differences. Not just due additional contributions because the way are developed electrolytes vs. non-electrolytes. Moreover, there still fundamental issues unresolved the...
