All phase equilibrium calculations performed in VLXE are based on the use of equations of state (EOS).

A very large number of equations of state have been proposed since van der Waals made the first EOS.

Eight EOS are included in VLXE Blend. Depending on the EOS a different number of mixing rules are included.
