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. The gas nnaturel can also be used as a chemical raw material. 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 areenvironmentally friendly cars.

What are the elements most likely to cause acid rain? Coal, natural gas and nuclear power generation?
The fuels used are different. Coal-fired power plants use coal, while gas-fired power plants use gaseous fuel. Coal is coal that can burn, also called charcoal. Coal is a solid combustible mineral that was gradually formed by ancient plants buried underground and undergoing complex biochemical and physicochemical changes.
Gas is the general term for gaseous fuels. It can burn and release heat and is used by city dwellers and industrial companies. There are many types of gas, including natural gas, artificial gas, liquefied petroleum gas, biogas and gasof coal.
Detailed information:
1. Gas field gas
Gas field gas is gas extracted directly from gas wells. The main component of gas field gas is methane, with a methane content of more than 90%. It also contains a small amount of carbon dioxide, hydrogen sulfide, nitrogen and traces of helium, neon, argon and other gases. the value is approximately 36 MJ/m.
2. Oil-associated gas
Low gas produced with oilHydrocarbon gas is called oil-associated gas. The methane content of oil-associated gas is about 80%, the content of ethane, propane and butane is about 15%, and the low calorific value is about 45 MJ/m.
3. Condensate gas field gas
Condensate gas field gas is a gas containing fractionslight oil. In addition to a large amount of methane, the condensate gas also contains 2-5% pentane and other hydrocarbons, with a low calorific value of about 48 MJ/m.

< p>Because acid rain is mainly caused by sulfur oxidizing substances and nitrogen oxides. Charcoal is therefore the easiest to trigger. Sulfur dioxide will be produced after burning the coal. When it accumulates to a certain amount, it falls with rain, forming acid rain.Yes
The main component of natural gas is methane
Methane is a greenhouse gas and will also destroy the ozone layer
p>
If methane is emitted directly When released into the atmosphere, it will cause a greenhouse effect and destroy the ozone layer.
But if methane is burned, it will generate water and carbon dioxide. Compared to burning coal, it also releases. sulfur dioxide, hydrocarbons, nitrogen oxides, etc. Generally speaking, it is cleaner and more environmentally friendly than coal and oil. However, if it is directly released into the atmosphere, it will pollute and damage the atmosphere.
