2Scope / Description
This part of GB/T 17747 specifies the calculation method for the compression factor of natural gas, natural gas containing artificial admixtures and other similar mixtures that exist only in gaseous state. The calculation method is to use the detailed mole fraction composition of the known gas and the relative pressure and temperature to calculate the compressibility factor of the gas. This calculation method is also called AGA8-92DC calculation method, which is mainly applied to pipeline gas transmission within the range of pressure p and temperature T where gas transmission and distribution are normally carried out, and the calculation uncertainty is about 0.1%. It can also be used for gases with a wider composition range in a wider pressure and temperature range, but the uncertainty of the calculation results will increase (see Appendix E). See GB/T17747.1 for a more detailed description of the application scope and application fields of this calculation method.
