Results are shown in Fig. 1, which reports the oil solubility in the
solvent rich phase and the selectivity of the solvent with respect to
the separation of the light components (EE-C14, EE-C16 and EEC18)
from the heavy components (EE-C20 and EE-C22). Selectivity
is defined as:
Sl/h = Yl/Xl
Yh/Xh
(2)
where Y and X are the mole fractions on solvent-free basis in the solvent
rich phase and in the liquid phase, respectively; the subscripts
l and h mark light and heavy components, respectively.
