摘要: 本文用PR状态方程推算低温高压含氢体系汽液相平衡.在计算中,考虑了正、仲氢的转化,并且采用两种方法考虑了量子效应.结果表明比原PR方程更精确地描述了汽液平衡.

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.
