The development of natural gas industry is of great significance to national economy and energy security

The natural gas industry refers to the industrial chain that uses natural gas as raw material to produce natural gas products through a series of extraction, processing, storage, transportation and utilization processes, and provides fuel and chemical raw materials for the society. Natural gas is a kind of combustible gas composed of methane and other main components, which has the characteristics of high calorific value, low pollution and wide application, and is an important energy resource.

The exploitation of natural gas is the first step in the natural gas industry. The mining process mainly includes exploration, drilling and extraction, exploration is to determine the existence and distribution of natural gas through geological exploration and other methods, drilling is to drill drill into the underground rock layer, extraction is to extract natural gas from the underground reservoir to the surface through suction and other methods. The exploitation of natural gas requires a large amount of equipment and technology, such as drilling equipment, production equipment and water injection equipment.

The processing of natural gas is to carry out desulfurization, dehydration, impurity removal and other processes to make it meet the requirements of market demand. The main equipment involved in the process are desulfurization tower, dehydrator and separator. The processed natural gas can obtain high-purity methane gas and some by-products, such as liquefied petroleum gas (LPG), natural gas condensate (CNG) and sulfur.

The storage and transportation of natural gas is the process of transporting processed natural gas to user areas through pipelines or ships. Natural gas is transported through pipeline is the most common way, need to build a large gas pipeline network system, and equipped with compressor station, gas transmission station and regulating valve and other facilities. Ship transportation is mainly used for long-distance or offshore natural gas transmission, which requires the construction of natural gas liquefaction plants and storage facilities.

The use of natural gas refers to the supply of natural gas as energy to users, including industrial, civil and transportation fields. Industrial utilization is mainly used for heating, combustion and chemical reactions in industrial production processes, civil utilization is mainly used for cooking, heating and gas power generation in residents' lives, and transportation utilization is mainly used for fuel for natural gas vehicles.

The development of natural gas industry is of great significance to national economy and energy security. As a clean, safe and safe energy substitute, natural gas can reduce the dependence on fossil energy, reduce environmental pollution and carbon emissions, and improve energy efficiency. On a global scale, the natural gas industry has become an important industry, providing countries with abundant energy resources and economic development power.

China's natural gas industry developed late, but has achieved rapid development in recent years. The main feature of China's natural gas industry is to take natural gas supply as the core, and gradually establish a complete industrial chain including exploration, development, processing, storage, transportation and utilization. China's natural gas industry is committed to increasing exploration and development efforts, improving natural gas production capacity and supply security capabilities, and promoting the continuous increase in the proportion of natural gas in the energy structure. At the same time, China's natural gas industry is also developing emerging fields such as liquefied natural gas (LNG) and natural gas chemical industry to improve the comprehensive utilization efficiency of natural gas.
