The junction pressure of Vapour Liquid Equilibrium (VLE) area on PT diagram of Fluid Mixture (see Fig. 1).
Fig. 1. Schematic PT diagram with Vapour Liquid Equilibrium and Pseudo-Critical Pressure (Ppc). |
The simplest estimate of Pseudo-Critical Pressure is the mole fraction weighted average:
p_{pc} = \sum_i x_i \, p_{c,i} |
where
mole fraction of the -th mixture component | |
critical pressure of the -th mixture component |
