The sulfur content of high-quality natural gas is almost non-existent, but some lower-quality natural gases may also contain a small amount of sulfur, mainly depending on the origin of the natural gas. The main component of hot air is methane, with the chemical formula CH4. After combustion, it produces CO2, H2O and a little N2O.
Methane is the shortest and lightest hydrocarbon molecule. It may also contain heavier hydrocarbon molecules, such as ethane (C2H6), propane (C3H8), and butane (C4H10), as well as varying amounts of hydrocarbons. sulfur containing gas. If natural gas does not undergo strict filtration and adsorption treatment, sulfur dioxide will be emitted after combustion.

Uses of natural gas:
1, natural gas can also be used as materialfirst chemical. Chemical production equipment using natural gas as raw material has low investment, low energy consumption, less land occupation, fewer personnel, good environmental protection and low operating costs.
2. Natural gas is widely used in residential and commercial gas ranges, water heaters, heating and refrigeration. It is also used in papermaking, metallurgy, quarrying, ceramics, glass and other industries. used for incineration, drying and dehydration of waste.
3. Emission levels of carbon monoxide, nitrogen oxides and hydrocarbons from natural gas vehicles are much lower than those from gasoline and diesel engine vehicles. They have no carbon deposits, no wear and have low operation. costs. These are environmentally friendly cars.
