Natural gas is a clean, convenient, high-quality, and efficient energy source,It has become an important commodity in the international energy market. Due to different origins or forms of natural gas, its physical and chemical properties vary greatly, including composition, calorific value, density, and combustion characteristics. During natural gas trading,The calorific value and density of natural gas are important parameters that indicate the quality of natural gas, with calorific value directly affecting transaction prices. The implementation of natural gas calorific value pricing can reflect the principle of pricing based on quality, which is necessary to align with international practices and contribute to the development of China's natural gas industry.

GC -9280Type of natural gasH2、CO、O2、CO2、CH4、CnHnThe complete set of component analysis system is a specialized analysis system applied to the analysis of component calorific value in natural gas pipelines. The system technology is accurate in measurement, fast in response speed, and can continuously analyze the measured gas for a long time. It adoptsEPCAutomatic control has the characteristics of reasonable structure, safe and reliable operation, high degree of automation, low maintenance, and strong self diagnostic protection function.
