What's the difference between gas, natural gas and liquefied petroleum gas?

In family life, the use of combustible gas is essential. Because every household has to make a fire to cook, gas can be used as an important substance in the fire. In normal use, we will find that some people use natural gas, some people use liquefied gas, and some people use gas. So what's the difference between these three gases?

First of all, from the distinction of acquisition methods. Natural gas, as the name implies, is natural gas. This gas is mostly collected in underground rock reservoirs. We know that there are different levels underground, and there are certain gaps between these levels, and some underground gases are formed between the gaps. After a series of collection, these gases form usable combustible gases;

Liquefied gas is obtained from petroleum, kerosene, fuel oil and other petroleum products. These oil products will produce a large amount of petroleum tail gas in the production process, which will be refined into combustible gas to provide liquefied gas for residents.

Finally, take a breath. Coal gas is processed from coal, which generally appears in the form of cans in life. In the user's home, you see cans of gas.

Then there is the difference in composition. The composition of natural gas is methane, ethane, propane or nitrogen. Its composition is high in purity, and in the combustion process, the unit mass can generate heat equivalent to 2.85 of liquefied gas. Because of its full combustion, there is no need for secondary processing in the collection process, which saves a lot of intermediate costs and is safe to use. Now it is often used in most residents' homes.

The main component of gas is carbon monoxide, in addition to hydrogen and methane. Because inhaling too much carbon monoxide can be toxic, gas is the most dangerous of the three gases. Residents should also pay more attention to the use process. The main components of liquefied gas are butane, butene and propylene. Its purity is high, and it is a colorless volatile combustible gas.

The difference of energy is that natural gas belongs to primary energy, which is more fully burned, and its acquisition method does not need intermediate treatment, and there are few harmful gases produced after combustion, so it is the safest and most suitable combustible gas for modern residents. Gas and liquefied gas are secondary energy sources, which will produce a lot of harmful gases after burning, so people use gas and liquefied gas less and less now. When conditions permit, people will choose natural gas as a combustible gas for household use, and the country also advocates the use of natural gas, so natural gas is better.

The above is the difference between the three, have you learned?
