APPLICATION OF THE BWR EQUATION TO PREDICT THE VAPOR-LIQUID EQUILIBRIA OF HYDROGENHYDROCARBON SYSTEMS

摘要

References(21) Cited-By(2) The applicability of the Benedict-Webb-Rubin equation to the vapor-liquid equilibria of hydrogen-hydrocarbon mixtures was studied. Nine binary and six multicomponent systems were tested over wide temperature and pressure ranges and the equation was shown to be successful. However, at low temperatures, errors became significant for heavy components. The predicted K-values were compared with those from the Chao-Seader correlation, and the former was shown to be better in general than the latter.
