The junction A property of a Fluid Mixture represented by the junction point of Vapour Liquid Equilibrium (VLE) area on PT diagram of Fluid Mixture (see Fig. 1).


It is characterized by pseudo-critical temperature

There are other no-linear methods to blend the components  to estimate the 
Pseudo-Critical Point but many engineering applications use

 and

 as the seed and then fit the values to match lab test data.


In case the fluid composition is not known one can use empirical 
Pseudo-Critical Point Correlations to assess the Pseudo-Critical Point.
