answer :
application of VLE :
- Vapor-liquid equilibrium
information is useful in designing columns for distillation,
especially fractional distillation, which is a particular specialty
of chemical engineers. Distillation is a process used to separate
or partially separate components in a mixture by boiling
(vaporization) followed by condensation. Distillation takes
advantage of differences in concentrations of components in the
liquid and vapor phases.
SUMMARY :
VLE DATA GENERALLY HELPFUL IN
DISTILLATION COLUMN, WHICH HELP TO DECIDE THE NO. OF STAGES.
