Fluid phase equilibrium and volumetric properties from the Chain-of-Rotators group contribution equation of state

A new group contribution equation of state, the Chain-of-Rotators Group Contribution (CORGC) equation, has been developed recently for the calculation of vapor—liquid phase equilibrium and volumetric properties of paraffins, naphthenes, aromatics, olefins, light gases and their mixtures. Comparisons...

Description
Summary:A new group contribution equation of state, the Chain-of-Rotators Group Contribution (CORGC) equation, has been developed recently for the calculation of vapor—liquid phase equilibrium and volumetric properties of paraffins, naphthenes, aromatics, olefins, light gases and their mixtures. Comparisons of CORGC calculations with data are presented here for pure fluid and mixture vapor—liquid coexistence properties. Predictions of the equation for systems not included in the original data base are also shown for pure fluid vapor pressures and mixture vaporization equilibrium ratios.
