【Abstract】 The Peng-Robison equation of state is used for predicting vapor-liquid equilibria of hydrogen containing systems at low temperature and high pressure. Quantum correction and the effect of ortho-para conversion of hydrogen were introduced into the P-R equation. Several ways of incorporating these effects into the original P-R equation were studied and the calculated results were compared.The incorporation of these effects led to a more accurate description of VLE than the original P-R equation of state.更多还原
