ActiveNatural gas—Technical explanation for calculation of physical properties from composition
天然气 通过组成计算物性参数的技术说明
Application Summary AI generated
This standard provides the technical methodology and calculation procedures for deriving physical properties of natural gas, such as density, calorific value, and compressibility factor, directly from its chemical composition. It is applied in the Chinese natural gas industry for custody transfer, quality control, and process engineering, ensuring consistent and accurate property determination across production, pipeline transport, and distribution systems. The standard is particularly relevant for gas analysis laboratories and metering stations where compositional data is used to verify energy content and flow calculations.
