GB/T 13610-2020 (English Version) PDF

Scope: This standard specifies the determination of the chemistry of natural gas and similar gas mixtures by gas chromatography and does not address all safety issues associated with its application. Use the safety and health operating procedures of this standard, and clarify the applicable scope of its limitations. Before GB/T 13610-2020 gas composition analysis by gas chromatography, the user is responsible for formulating an analysis method for the corresponding composition. This standard applies to the analysis of the range of natural gas components shown in Table 1, and also to the determination of one or several components. Table 1 Components and concentration ranges of natural gas. 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 Neoterane 0.01-2 Isopentane 0.01-2 N Pentane 0.01-2 Hexane 0.01-2 Heptane and heavier components 0.01-] Carbon monoxide 0.01-1 Hydrogen sulfide 0.3-30 "Conventional natural gas generally does not contain carbon monoxide components, and carbon monoxide may be contained in special samples such as coal-derived natural gas Components can be tested using the methods specified in this standard.
