A generalized technique is presented for the calculation of the pure component parameters for use in a general two-parameter equation of state. The method requires as input data the vapor pressure and saturated liquid volume of a component at a given temperature, and is both accurate and simple to use. Correlations for the calculation of the parameters are presented for the van der Waals, Redlich-Kwong and Peng-Robinson forms of cubic equations of state. A comparison is made between the new method and the corresponding-states approach.
