摘要： 为了使输气管道能够稳定、安全、经济地运行,实现科学的调度和管理,有必要对输气管道输送工况
进行研究。在输气管道运行压力达10MPa状态下,天然气的热物性参数若用理想气体状态方程进行分析计算,将
会产生很大的误差。应用L-E-E方程求解实际气体的压缩因子、实际气体密度、比热、绝热指数、焦耳-汤姆逊效
应系数、熵、焓等参数并编制了计算软件。计算结果表明,应用L-E-E方程计算天然气物性参数时,其计算精度
高,能够较好地满足工程实际的需要。

Abstract: For gas pipeline, simulating the working condition was necessary in order to work safely and economically and manage rationally. Some gas pressure was up to 10 MPa in the pipeline, in which the result by equation for ideal gas has the greater error. L-E-E equation was applied to solve the physical parameters such as the compression factor, practice gas density, specific heat, adiabatic index, entropy, enthalpy and so on. And the program was compiled to calculate the properties. The calculate results show that L-E-E equation is much accurate and can be applied widely in the practice.
