7.6.8 High-pressure liquid-vapour equilibrium.
The calculation of liquid-vapour equilibrium at high pressures is based on the equilibrium
conditions
fi(l) = fi(g), i= 1. 2... , k , (7.37)
T(l) = T(g), (7.38)
p(l) = p(g) (7.39)
with pressure and fugacities calculated using the equations of state capable of expressing the
state behaviour of both phases.
