摘要
基于平衡各相分逸度相等的判据 ,分别推导出了石油烃类体系在常压和高压下的固液平衡方程 ,并对所得方程的应用进行了讨论 ,推荐了分别用于计算液相和固相非理想性的热力学模型 .
Solid-liquid equilibrium equations for hydrocarbons systems under atmospheric pressure and high pressures were derived in this work based on the equality of the fugacity of individual components in the two equilibrium phases. The applications of the derived equations have been discussed extensively and the thermodynamic models used to calculate the non-idealities of the liquid and solid phases were proposed.
