An Energy-Based Cohesion Function for Cubic Equations of State

81-97

Acohesion function is derived for cubic equations of state of van derWaals type, based on the behaviour of the residual internal energy of pure fluids; it contains two fluid-specific constants and is therefore suitable for nonpolar and polar fluids. The characteristic constants are obtained for the van derWaals, Redlich-Kwong and Peng-Robinson equations for 846 fluids by fitting cohesion parameters computed from vapour pressures taken from the DIPPR database. Comparison with similar functions proposed in the literature shows that the new function is generally better. A corresponding states generalization is presented using the acentric and critical compressibility factors.
