ActiveNatural gas—Calculation of thermodynamic properties—Part 2:Single-phase properties (gas，liquid，and dense fluid) for extended ranges of application
天然气 热力学性质计算 第2部分：扩展应用范围的单相（气相、液相和稠密相）流体性质
Application Summary AI generated
This standard specifies calculation methods for thermodynamic properties of natural gas in single-phase states, including gas, liquid, and dense fluid, under extended pressure and temperature ranges. It is applied in the petroleum and natural gas industry for engineering design, pipeline transport, and process simulation where accurate property data are required beyond conventional conditions. The standard supports procurement and operational decisions by ensuring consistent property predictions for custody transfer, flow metering, and equipment sizing.
