A modified perturbed hard-sphere-chain equation of state by Eslami [H. Eslami, Fluid Phase Equilibr. 216 (2004) 21–26], is extended to mixtures. The resulting equation of state for mixtures consists of two temperature-dependent parameters as well as an additional parameter, reflecting the segment size for pure components. The temperature-dependent parameters of the equation of state are correlated...
A modified perturbed hard-sphere-chain equation of state has been employed to calculate the PVT properties of fluids. Generally, two temperature-dependent parameters; an effective van der Waals covolume and the strength of the attractive forces between two nonbonded segments, and a third parameter representing the number of chains per molecule appear in the existing perturbed hard-sphere-chain equations...
