Natural gas (natural gas) also known as oil gas, liquefied petroleum gas, petroleum gas. The main component is methane, but also contains a small amount of ethane, butane, pentane, carbon dioxide, carbon monoxide, hydrogen sulfide, etc.. Oil and gas only called natural gas; oil and oil gas, the petroleum gas called oil gas or petroleum gas. The chemical composition of natural gas and its physical and chemical properties vary from place to place, no hydrogen sulfide is colorless, odorless, flammable and explosive gases, density of 0.6 ~ 0.8g/cm3, lighter than air. Usually referred to as dry gas containing more than 90% of methane, containing less than 90% of methane is called moisture.
Artificial gas is the main component of carbon monoxide.The main components of the gas are CO, hydrogen and alkanes, olefins, aromatics, etc.. The gas is toxic because of the CO, and the body of the aromatics to hemoglobin, causing hypoxia, make people remain unconscious or even death, can also make people dizzy, nausea and collapse at low concentrations.
The main content of gas is carbon monoxide, hydrogen, etc.. The main content of natural gas is methane. When the two gases are detected, the parameters are different. Carbon monoxide poisoning. So they are treated as toxicity. Natural gas is flammable and explosive.
No, gas is the gas that occurs when the coal is not completely burned, the main component is carbon monoxide, colorless, odorless, toxic, and was absorbed by the human and animals in the blood after the combination of hemoglobin can cause poisoning. Also called coal poisoning. Natural gas is a multicomponent gas mixture, in which methane is the main component of alkanes, the majority, and a small amount of ethane, propane and butane, in addition also contains hydrogen sulfide, carbon dioxide, nitrogen and water vapor, and the amount of inert gas, such as helium and argon. Under standard conditions, methane to butane exists in a gaseous state and pentane is a liquid.
