Abstract
Systems with azeotropes cannot be separated by simple distillation
since the vapor and liquid compositions are the same. Variation of
the applied pressure can shift the azeotropic composition out of the
range of purification of a single column or may allow pressure swing
operation of two columns. Because of the sensitivity of column size
to accurate estimates of the relative volatility, it is important to use
reliable phase equilibrium thermodynamics when exploring the
possibility of varying pressure to avoid an azeotrope. Based on an
analysis of the pressure sensitivity of azeotropic compositions, we
show examples of the impact of different modeling strategies for
binary and multicomponent mixtures.
