A New Equation Of State Based On Perturbation Theory

Based on the Carnahan and Starling hard sphere equation of
Compressibility, an equation of state has been derived. Conditions that must be
met by all equations of state are applied in order to obtain attractive term or non
- ideal compreSSibility term of the equation. Second virial coefficient and
acentric factor arc used in the derivation of the equation of state. In this
equation, compressibility factor is not constant at critial point as it is in other
equations oC state. II has been shown that PYT data of hydrocarbon can be
generated with accuracy through the use of this equation of statc . PYT data
calculated by this equation has been compared with data obtained through the
use of Peng Robinson, Soav - Redlich - Kowng and Redlich - Kowang equations
of state.
