Models in VLXE

 Top  Previous  Next

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

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

VLXE offers six different EOS.

 

Equations of state included

•Peng/Robinson (PR) with standard mixing rules
•Soave/Redlick/Kwong (SRK) with standard mixing rules
•Sanchez/Lacombe (Original)
•Sanchez/Lacombe (Ideal gas limit)
•PC-SAFT
•Copolymer PC-SAFT
•CPA
•simplified PC-SAFT
