The apex point of Vapour Liquid Equilibrium (VLE) area on PT diagram of Fluid Mixture (see Fig. 1).
It is characterized by critical temperature and critical pressure .

The simplest estimate of Pseudo-Critical Point is the mole fraction weighted average:
T_{pc} = \sum_i x_i \, T_{c,i} |
p_{pc} = \sum_i x_i \, p_{c,i} |
where
mole fraction of the -th mixture component | |
critical temperature of the -th mixture component | |
critical pressure of the -th mixture component |
