Abstract
In the oil and gas industry, there is growing interest in using the PC-SAFT equation of state for predicting the
phase behaviour and physical properties of hydrocarbons. This article demonstrates how this equation of state
can be used in combination with the direct energy minimization algorithm of an isochoric-isothermal system
for calculating vapour-liquid equilibrium parameters of hydrocarbons. The proposed approach is tested on
four substances: methane, ethane, propane, and n-butane.
