Liquid-Liquid Phase Equilibria

  • Hans-Jörg Bart
Part of the Heat and Mass Transfer book series (HMT)


The design of an extraction process and the layout of an extraction apparatus is based on thermodynamics, hydrodynamics, and mass transfer. Among these, the thermodynamic data for the distribution of the solute between the two phases is the most important. There are several available source books on liquid-liquid equilibria (LLE), e.g. for organic solutes [Wisniak & Tamir (1980), Sorensen & Ant (1979–1980)]. The most commonly used correlations for LLE are also implemented in simulation tools like ChemSep®, ASPEN®, HYSIM®, etc. Unfortunately, the available data may be incomplete or unreliable which then makes laborious experimental work necessary.
