Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 17281-1998 "Determination of butane to hexadecane in natural gas by gas chromatography", and
GB/T 17281-1998 compared to the main technical changes are as follows.
- In Chapter 3, "Principle", the packed column is changed to methyl siloxane capillary column;
- In Chapter 4, "Materials", the "4.4 coolant" is removed;
--- modified the "5.1.1 column furnace" in the technical content;
--- delete the "5.3 column" on the packed column of all the contents of the increase in the contents of the capillary column;
Figure 1, Figure 2 and Figure 3, with the separation of the capillary chromatogram 1 and 2 instead of;
--- modified 5.7 in the pipeline diameter, pipeline diameter from 0.7mm to 1mm to 0.7mm ~ 4mm;
--- to 5.9 in the "potential recorder" to "chromatography workstation", and increase the technical content of the chromatographic workstation;
--- delete the "5.10 Integrator";
- The component concentration range in Table 1 was modified against "GB/T 13610"
--- "7.1.1 General requirements" is added in 7.1 "Setting the instrument operating conditions".
This standard is proposed by China National Petroleum Corporation.
This standard is under the jurisdiction of the National Natural Gas Standardization Technical Committee (SAC/TC244).

Determination of butane to hexadecane hydrocarbons in natural gas
Gas chromatography
1 Scope
This standard specifies the quantitative analysis of butane to hexadecane hydrocarbons in natural gas.
This standard applies to the determination of butane to hexadecane hydrocarbons in natural gas.
Note 1. Butane and pentane hydrocarbon components are individually determined, and higher carbon hydrocarbons are classified as carbon.
Note 2. The results of this method and GB/T 13610 unaligned results can be combined to obtain a complete analysis of the results, GB/T 13610 Determination of component package
Containing helium, hydrogen, oxygen, nitrogen, carbon dioxide, methane to pentane, hexane and heavier hydrocarbon components (C6).
Note 3. This standard is used in conjunction with GB/T 13610. The results of methane to pentane can be obtained by the method described in GB/T 13610, the hexane to hexadecane
The results are described in the methods described in this standard.
2 normative reference documents
The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article
Pieces. For undated references, the latest edition (including all modifications) applies to this document.
GB/T 4946 Glue term
GB/T 5274 Preparation of gas mixtures for gas analysis calibration
Composition analysis of natural gas - Gas chromatographic method GB/T
3 principle
Natural gas samples were injected into the capillary column of methylsiloxane. Using the program to heat up the separation, the composition of the flame with ionization
Detector (FID) for detection.
The quantitative determination of butane to hexadecane is either calibrated with a standard gas mixture containing butane and the remainder
The response of all hydrocarbons, or the pentane content measured with GB/T 13610.
When the results of the analysis are combined with the results obtained in GB/T 13610, the sum of the components is determined to be normalized
To 100%.
4 material
4.1 Carrier gas
Helium or nitrogen, the purity of not less than 99.99% 1), anaerobic and water.
1) If the purity of the gas is lower than specified, it is advisable to check the presence of impurities. That is, even if the carrier gas nitrogen or hydrogen purity is appropriate
It is stipulated that some of the impurities present in these gases will still interfere with the analysis, and in this case appropriate purification is necessary.
4.2 auxiliary gas
4.2.1 Hydrogen. Purity of not less than 99.99%.
4.2.2 Air. No hydrocarbon impurities.
