2Scope / Description
This part of GB/T 30491 specifies the calculation methods for the volumetric and thermal properties of natural gas, natural gas containing artificial admixtures and other similar mixtures that exist only in gaseous state. This section applies to pipeline transport gas within a certain range of pressure (p) and temperature (T) during gas transmission and distribution. For volumetric properties (compressibility factor and density), the calculated uncertainties are approximately ±0.1% (95% confidence interval). For thermal properties (eg, enthalpy, heat capacity, Joule-Thomson coefficient, sound velocity), the calculated uncertainties are usually larger.
