The equation of state has been widely used to predict the thermodynamic properties and phase
behavior of pure and multi-component systems in petroleum and chemical industries. However,
they often fail in highly polar, hydrogen bonding and associating systems. Association equation of
state (AEOS) can be used for the discrepancy due to the association concept. AEOS uses the
physical and chemical contributions to evaluate the phase behavior of associating fluids. In this
work, a new Peng-Robinson based association equation of state has been developed. The new
proposed AEOS is used to correlate the saturated properties of 19 associating pure compounds. In
addition, the new AEOS satisfactorily extended to mixtures containing associating and nonassociating
compounds and the VLE behavior of several important associating binary systems
such as water/hydrocarbon, alcohol/hydrocarbon, alcohol/CO2 and the quaternary system of
H2O/CH4/CO2/H2S has been represented. The results of this work are in good agreement with the
other works and experimental results.
