Natural gas is contained in underground porous rocks, including oil and gas, gas field gas, coalbed methane, mud volcanic gas and biogas, and a small amount comes from coal seams. It is a high-quality fuel and chemical raw material.
Natural gas is mainly used as fuel to make carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. Natural gas is mainly composed of gaseous low molecular hydrocarbons and non-hydrocarbon gases.

Advantages of natural gas
1, safe to use
Natural gas is one of the safer fuels. It contains no carbon monoxide, does not cause poisoning, and is lighter than air. Once leaked, it is easy to spread out and not easy to gather and cause explosion. LPG is heavier than air. If it leaks, it will easily accumulate indoors and cause an explosion. ?
2. Economical and practical
The price of natural gas is stable and cheaper than liquefied petroleum gas. The calorific value of natural gas is one third of that of liquefied petroleum gas. Taking a city as an example, the average gas consumption of each household is 5 cubic meters. After conversion to natural gas, the gas consumption will rise to about 15 cubic meters. At present, the price of civil pipeline liquefied gas is 17 yuan /m3, and the price of civil natural gas is 4 yuan /m3. After conversion to natural gas, the comprehensive cost is reduced by about 30%. ?
3. High quality
In some cities, the annual consumption of pipeline liquefied gas has exceeded the designed gas supply capacity, and problems such as low air pressure and ignition failure often occur. Adequate natural gas source and stable calorific value will effectively solve the problem of gas users' difficulty in using gas during peak hours. Burning natural gas without black smoke and carbon deposition will greatly improve the home environment and improve the quality of life of citizens.
