The main components of natural gas are alkanes, of which methane accounts for the vast majority, and a small amount of ethane, propane and butane. In addition, there are generally hydrogen sulfide, carbon dioxide, nitrogen and water vapor, a small amount of carbon monoxide and a small amount of rare gases such as helium and argon.
Before natural gas is delivered to the end user, mercaptan, tetrahydrothiophene, etc. It should be used to increase the smell of natural gas to help leak detection.
Extended data:
The advantages of natural gas are:
Environmental protection: Natural gas is a clean and environmentally-friendly high-quality energy source, and contains almost no harmful substances such as sulfur and dust. Compared with other fossil fuels, the carbon dioxide produced during combustion is less, and the greenhouse effect is lower, thus fundamentally improving the environmental quality.
Economical: Compared with artificial gas, natural gas has the same year-on-year calorific value price and is clean, which can prolong the service life of stoves and help users reduce maintenance costs. Natural gas is a kind of clean fuel gas, and its stable supply can improve air quality, thus providing new impetus for economic development in this region, promoting economic prosperity and improving the environment.
Safe and reliable: Natural gas is non-toxic, easy to disperse, lighter in specific gravity than air, and should not be accumulated into explosive gas, so it is a relatively safe gas.
Improve life: With the use of safe and reliable natural gas in families, the home environment will be greatly improved and the quality of life will be improved.
Calculation of oxygen consumption of natural gas: 1 m3 natural gas (purity 100%) requires about 2.0 m3 of oxygen and about 100 m3 of air for complete combustion.
