Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 13610-2014 "Gas Chromatography Method for Composition Analysis of Natural Gas". This standard and GB/T 13610- Compared with.2014, in addition to editorial changes, the main technical changes are as follows. ---Added the "carbon monoxide" component in the "range", the concentration range is "0.01%~1%" (see Chapter 1); ---The standard gas concentration requirement is revised to "For components with a mole fraction not greater than 5%, compared with the sample, the corresponding component in the standard gas The mole fraction should not be greater than 10%, nor less than 1/2 of the corresponding component concentration in the sample. For groups with mole fraction greater than 5% The concentration of the corresponding component in the standard gas should not be less than 1/2 of the concentration of the component in the sample, nor more than twice the concentration of the component. The minimum concentration of the components in the standard gas should not be less than 0.1%” (see 4.2, 4.2 in the.2014 edition). ---Modified the expression of precision. The boundary point of the concentration range of the components changed from the original discontinuous to continuous without crossing. Such as Change the boundary points "0~0.09" and "0.1~0.9" to "x< 0.1" and "0.1≤x< 1.0" (see Chapter 8, Chapter 8 of the.2014 edition chapter). This standard was proposed and managed by the National Natural Gas Standardization Technical Committee (SAC/TC244). Drafting organizations of this standard.

Before using this standard, the user is responsible for Safety and health operating procedures, and clearly defined the scope of application.

1 Scope

This standard specifies the analytical method for determining the chemical composition of natural gas and similar gas mixtures by gas chromatography. This standard applies to the analysis of the range of natural gas components as shown in Table 1, and it also applies to the determination of one or several components. Table 1 Composition and concentration range of natural gas Component Concentration range Mole fraction y/% Helium 0.01~10 Hydrogen 0.01~10 Oxygen 0.01~20 Nitrogen 0.01~100 Carbon dioxide 0.01~100 Methane 0.01~100 Ethane 0.01~100 Propane 0.01~100 Isobutane 0.01~10 N-butane 0.01~10 Neopentane 0.01~2 Isopentane 0.01~2 N-pentane 0.01~2 Hexane 0.01~2 Heptane and heavier components 0.01~1 Carbon monoxidea 0.01~1 Hydrogen sulfide 0.3~30 a Conventional natural gas generally does not contain carbon monoxide components. The carbon monoxide components that may be contained in special samples such as coal-based natural gas can be specified in this standard. Method for detection.
