This article reviews the results of experiments underway since 1950 studying the solid solubility of n‐alkanes (from ethane up to n‐triacontane) in methane and the factors influencing the global phase equilibrium behavior of the related binary mixtures. The methodology used consists of a series of comparisons of data in the composition‐temperature and pressure‐temperature diagrams. The kind of global phase diagram of the binary mixtures of methane referred to in the present article is found to be dependent of the ratio between the triple‐point temperature of the generic n‐alkane and the critical‐point temperature of methane. The Peng‐Robinson (1976), Predictive Soave‐Redlich‐Kwong, and Predictive Peng‐Robinson (1978) equations of state have been applied and compared with respect to the calculation of bivariant, univariant, and invariant equilibrium data involving solid n‐alkanes in binary mixture with methane. The fugacities of the solid n‐alkanes have been calculated by means of the so‐called classic approach. © 2018 American Institute of Chemical Engineers AIChE J, 64: 2219–2239, 2018

固体正烷烃在甲烷中的溶解度：数据分析和模型评估

本文回顾了自1950年以来正在进行的实验结果，研究了正烷烃（从乙烷到正三烷烷）在甲烷中的固溶度以及影响相关二元混合物整体相平衡行为的因素。所使用的方法包括组成-温度和压力-温度图中的一系列数据比较。发现本文中提到的甲烷二元混合物的整体相图类型取决于通用正构烷烃的三点温度与甲烷的临界点温度之间的比率。分别采用了Peng-Robinson（1976），Predictive Soave-Redlich-Kwong和Predictive Peng-Robinson（1978）的状态方程，并将其与双变量，单变量，以及涉及与甲烷二元混合物中的固体正烷烃的恒定平衡数据。固体正构烷烃的逸度已通过所谓的经典方法进行了计算。©2018美国化学工程师学会AIChE J，64：2219–2239，2018年
