Saturated properties prediction in critical region by a quartic equation of state
A diverse substance library containing extensive PVT data for 77 pure components was used to critically evaluate the performance of a quartic equation of state and other four famous cubic equations of state in critical region. The quartic EOS studied in this work was found to significantly superior to the others in both vapor pressure prediction and saturated volume prediction in vicinity of critical point.
KEY WORDS: Equation of state, Saturated properties, Critical region
