摘　　要：天然气临界温度和临界压力是天然气有关计算的基础参数,国内对混合物的物理属性和其相应状态原则的计算方法的研究较少。在相关理论的基础上,归纳了酸性天然气临界温度和临界压力的计算方法,给出相关的计算实例并进行对比分析。结果表明,Alireza Bahadori和Saeid Mokhatab等改进的快速估算方法在超出其压力或温度范围时,与Wichert和Aziz方法偏差较大;Elsharkawy的密度校正方法与Wichert和Aziz方法具有良好的一致性。Natural Gas critical temperature and critical pressure are the basic parameters of related natural gas cal- culation, which provide physical properties of the mixture and its corresponding approaches of the related principle of state. Civil relevant article is rarely. On the basis of finishing and collecting the related theory method, this pa- per summarizes the acid gas critical temperature and critical pressure calculation method, gives the relevant calcula- tion example and compared it. The results show that improved fast estimation method of Alireza Bahadori and Saeid Mokhatab beyond its range of the pressure or temperature, is bigger than Wichert and Aziz method, calculated re- sults is equivalent to acid gas correction; Elsharkawy density correction method and Wiehert and Aziz method has good consistency.
