Fig. 1. Schematic PT diagram with Vapour Liquid Equilibrium and Pseudo-Critical temperature (T_pc).

The simplest estimate of Pseudo-Critical Temperature is the mole fraction weighted average:

p_{pc} = \sum_i x_i \, p_{c,i}

where

	mole fraction of the -th mixture component
	critical temperature of the -th mixture component
