Natural gas is widely used in today's society due to its advantages of clean, low-carbon, efficient use and abundant reserves. The international standard "ISO 13686 Natural Gas Quality Index" clearly stipulates the composition of natural gas, so the quantitative analysis of natural gas composition has become very important. important.

The analytical standard deviations of methane, ethane, propane, carbon dioxide, nitrogen, hydrogen, carbon monoxide and C4+ in natural gas samples were 0.072%, 0.002%, 0.000%, 0.013%, 0.018%, 0.02%, 0.014%, and 0.037%, respectively; In terms of accuracy, compared with the analytical values of the gas chromatography method, the standard deviations of the online analysis system for the eight components of methane, ethane, propane, carbon dioxide, nitrogen, hydrogen, carbon monoxide and C4+ were 0.234%, 0.141%, respectively. The results show that the system has good accuracy.
