1、 Analysis of natural gas:
according toGB17820-1999Natural GasGB18047-2000According to current national standards such as "Compressed Natural Gas for Vehicles", the natural gas extracted from gas fields or oil fields is pre treated and transported through pipelines as commercial natural gas5The technical indicators include high-level heat generation, total sulfur, hydrogen sulfide, carbon dioxide, and water dew point, with high-level heat generation analyzed by gas chromatography.
GC-7820typeThe gas chromatograph is equipped with thermal conductivity and hydrogen flame detectors, and adopts a ten way valve blowback process, which can be completed with one injectionGB/T13610-2003In the natural gas specified in the regulationsC1-C6reachC6+Waiting for hydrocarbon components andHe、H2、O2、N2、CO2Analysis of inorganic gases; Based on the obtained content of each component, and then according toGB/T 11062-1998The calculation method for natural gas calorific value, density, average density, and Wopo index calculates the high-level calorific value of natural gas

| Note: 1. The standard reference conditions for gas volume in this standard are 101.325kPa and 20 ℃ 2. The natural gas transmission pipeline established before the implementation of this standard should have no free water in the natural gas under pressure and temperature conditions at the natural gas transfer point. No free water refers to natural gas that cannot be separated from free water by mechanical separation equipment | |||

2、 Analysis of Liquefied Petroleum Gas
1. Composition analysis of liquefied petroleum gas
According to the current national standard GB11174-1997 "Liquefied Petroleum Gas", the petroleum liquefied gas produced by oil refineries is mainly composed of constant components such as ethane, ethylene, propane, propylene, n-butane, isobutane, n-butene, isobutene, isobutene, maleic anhydride, n-pentane, and isopentane.
GC-7820 typeBy using flash evaporation injection method, the concentration of the above-mentioned components in liquefied petroleum gas can be determined in one injection. Users can use this concentration toGB/T12576-1997 Calculation of vapor pressure, density, and motor octane number of liquefied petroleum gas.
| Determination of components | Range of content in liquefied gas | Determination of components | Range of content in liquefied gas |
| methane | 0.01%-1% | isobutylene | 0.01%-10% |
| ethane | 0.01%-1% | maleic | 0.01%-10% |
| ethylene | 0.01%-1% | Reverse Butene | 0.01%-10% |
| propane | 0.01%-20% | N-pentane | 0.01%-5% |
| propylene | 0.01%-50% | Isopentane | 0.01%-5% |
| Butane | 0.01%-20% | 1,3-Butadiene | 0.01%-5% |
