This calculation method is detailed in known gas composition and molar fraction related pressure and temperature of gas and the compression factor. This calculation method is also known as AGA8-92DC calculation method is mainly used in the Gas Transmission and Distribution of normal pressure p and temperature T within the tube gas, calculated uncertainty about 0. 1%. Also available in a wider range of pressure and temperature, for a wider range of gas composition, but the calculation of uncertainty will increase (see Appendix E).

Calculation of compression factor of natural gas Part 2. The calculation of molar composition1 ScopeThis section GB/T 17747 provides for natural gas, including labor and other similar blend a mixture of gaseous state only memory When the compression factor calculation method. This calculation method is composed of a known gas mole fraction of detailed and relevant pressure and temperature to calculate the gas compressibility factor. This calculation method is also known as AGA8-92DC calculation method is mainly used in pressure p and temperature T Gas Transmission and Distribution of normal Pipe gas range, calculation of uncertainty of about 0.1%. Also available in a wider range of pressure and temperature for a wider composition range of gas Body, but the results will increase the uncertainty (see Appendix E). About the scope of application of the calculation methods and applications described in more detail, see GB/T 17747.1.2 Normative referencesThe following documents for the application of this document is essential.

Meaning and unit symbol appears in the text represented Mitsuke Record A.4 Calculation4.1 Principle AGA8-92DC equation calculation method used is based on the concept. the nature of the capacity of pipeline natural gas composition characterized by And calculations. Composition, pressure and temperature are used as input data calculation method. This calculation method requires detailed molar gas composition analysis. The analysis included more than 0.00005 mole fractions of all components. For a typical gas pipe, assay components including carbon number up to all of C7 or C8 hydrocarbons, and N2, CO2 and He. Other gases, points Analysis of steam need to be considered such as H2O, H2S and C2H4 and other components. Artificial gas, H2 and CO may also be an important component of the analysis. 4.2 AGA8-92DC equation AGA8-92DC calculation method AGA8 detailed characteristic equation (expressed as the following equation AGA8-92DC, see GB/T 17747.1); ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 17747.2-2011_English be delivered?Answer: Upon your order, we will start to translate GB/T 17747.2-2011_English as soon as possible, and keep you informed of the progress.
