1 Scope

This standard specifies requirements for a detailed analysis of the operation of natural gas pipeline the heavy hydrocarbon components by gas chromatography, in order to use the appropriate equation of state Calculation of natural gas hydrocarbon dew point. This standard applies to the highest dew point temperature (critical temperature condensate) at 0 ℃ ~ -50 ℃, the highest pressure dew point in 2MPa ~ Gas 5MPa between.

For a given composition of natural gas, the pressure at its highest dew point is an intermediate value of gas transmission and distribution pressure. Full analysis of the components of natural gas They include inert component and to C12 hydrocarbon component. When He, H2, water and sulphide content of less than 0.01% (mole fraction), this analysis is not necessary The content of these components. Gas composition analysis can be divided into two parts is completed, the major component (N2, CO2 and C1 ~ C5 hydrocarbon component) in accordance with GB/T 27894 (All parts) or GB/T 13610 for analysis, and hydrocarbon components (C5 ~ C12 hydrocarbon components) higher carbon number analysis should meet this standard to Analysis of the requirements. ......
