The difference between gas and natural gas, the difference between gas and natural gas

As a high-quality and clean energy source, natural gas has four major advantages compared with coal gas alone:

First, the calorific value is high, reaching 8800 kcal, which is higher than that of gas;

Second, the purity is high, the composition of 95 is methane, which is completely combusted, does not contain toxic and harmful impurities such as sulfides, and has no pungent odor;

Third, the pressure level of the pipeline is high, dozens of times higher than that of gas, and the pressure range is large, making it easier to achieve sufficient gas supply; Fourth, the service life of the pipeline is long, and it can be used 3 times longer than gas under the same conditions, and the maintenance cost is low.

After using natural gas, the time spent by residents to boil water and cook can be shortened by half compared with the use of gas, and the required cost, according to the city's preliminary determination of twice the ** of gas, because the calorific value of natural gas is also more than twice that of gas, so the consumption affordability of residents should not be affected. Moreover, the oil stain and choking smell often brought by gas in the past will no longer appear, which is not only convenient for people's life, but also conducive to people's health. It is understood that from the use of natural gas to natural gas, the residents' original gas stoves and meters can still be used after the transformation, and the cost is only a few dozen yuan.

What is the difference between natural gas and gas?

1.The ingredients are different.

Coal gas is a mixture of gases, mainly composed of carbon monoxide, methane and hydrogen, of which carbon monoxide is the most important.

Natural gas is dry gas, the main component is methane and has a high purity, unlike coal gas, which contains multiple gases.

2.**Different.

Coal gas is called gas because it is made from coal.

Natural gas, on the other hand, is extracted from oil and gas fields, that is, from the ground.

3.The harmfulness is different.

The amount of carbon monoxide is still present after the gas is burned, and if there is a gas leak, it can cause poisoning to the user.

Carbon monoxide will only exist when natural gas is burned in, which is generally non-toxic, harmless and safer.

4.The cooktop is different.

Friends who know about household gas know that natural gas and coal gas cannot be mixed.

Because the pressure of gas is large, the orifice diameter of the gas nozzle is small, while the pressure of natural gas is small, and the orifice diameter of the gas nozzle is larger.

Natural gas is a natural mixed combustible gas based on methane and ethane.

So the rest is to know what "gas" is first.

Many people have a misunderstanding of "gas", will mistakenly call liquefied petroleum gas "gas", the actual liquefied petroleum gas is a mixed combustible gas based on propane and butane, colorless and odorless (the odor is artificially added), generally prepared by chemical methods.

If it is a real "gas", it is generally made of hot coal through water (steam), the main components include hydrogen, carbon monoxide, etc., which is a mixed combustible gas made artificially, because the calorific value is low, and it is easy to cause poison after leakage, so it is generally more commonly used as a chemical raw material, and now it is generally not directly used as a civil fuel.

GasIt is prepared by the factory with coal as the main raw material through chemical anti-annihilation inspection, and its main components are carbon monoxide, hydrogen and methane. Among them, carbon monoxide is a toxic gas, commonly referred to as gas poisoning, in fact, refers to carbon monoxide poisoning, and gas is easy to form a first-class mixture with air, which should be highly valued when used.

Natural gasIt is contained in the underground porous rock formation, the main component is methane, the specific gravity is about, lighter than air, and the ridge has the characteristics of colorless, odorless and non-toxic. Natural gas companies add odorant (tetrahydrothiophene) in accordance with the ** regulations to help users sniff it. Natural gas can suffocate people when it reaches a certain level in the air.

Difference Between Gas and Natural Gas:

Natural gas is a gas well exploited by live oil concomitant. The main component of Pure Eggplant is CH4 methane, and the calorific value is 8000-12000 kcal.

Coal gas is a mixture of gas, generally some factories with coal as fuel, such as iron and steel plants, aluminum plants, coke plants, and chemical plants produce companion organisms, mainly carbon monoxide, mixed with air in a certain proportion.

Overall, natural gas is one of the safer gases, it does not contain carbon monoxide, it is also lighter than air, once leaked, it will immediately spread upward, it is not easy to accumulate to form ** gas, the safety is relatively higher than other combustion gases, and now the vast majority of residential gas has been changed to natural gas.

The differences between coal gas and natural gas are as follows:

1. Composition.

The main component of natural gas is methane, or ethane, propane, and the content of other magazines is very small, so the purity of natural gas is high. Gas, on the other hand, is a mixture of various gases, including carbon monoxide, methane, hydrogen, etc., and even contains impurities such as water and hydrogen sulfide, so the purity is low.

In addition, natural gas is colorless and odorless, and less harmful gases are produced during combustion, so it is also more environmentally friendly and safe; The carbon monoxide in gas, on the other hand, has a strong odor, commonly known as "gas odor", so a leak may cause gas poisoning.

2. Combustion sufficiency.

Natural gas with high purity belongs to the primary energy source, no secondary processing is required when obtaining the gas source, and the combustion is more sufficient and will not produce harmful gases, so now natural gas can be said to be the most widely used and recommended safety gas source. Coal gas, on the other hand, is a secondary energy source, and the combustion adequacy is not as high as natural gas, and it will also produce some harmful gases more or less, and if there is a leak, it is easy to cause accidents, so it is basically not recommended to use gas now.

3. Pressure value.

There is also a difference in the pressure value between natural gas and coal gas. The natural gas pressure value is about 3000pa, and the gas pressure value is slightly lower, about 2000pa, which directly makes the gas nozzle diameter used by the two gas sources also very different, and the two are not interconnected. Therefore, if the natural gas used in the home is changed to natural gas in the later stage, then the pipes and gas stoves used need to be replaced or renovated.

Summary. Coal gas is prepared from solid raw materials such as coal or coke through dry distillation or vaporization, and its main components are carbon monoxide, methane and hydrogen. Therefore, the gas is toxic and easy for the air to form a ** mixture, which should be used with great attention.

Natural gas is a broad term for naturally occurring gases buried in formations. However, the so-called natural gas usually refers to a hydrocarbon-rich combustible gas stored in the deeper part of the formation, while natural gas that coexists with oil is often called oilfield associated gas. Natural gas is converted from organic matter hundreds of millions of years ago, and the main component is methane, in addition, according to different geological formation conditions, it also contains different amounts of low-carbon alkanes such as ethane, propane, butane, pentane, hexane, and non-hydrocarbon substances such as carbon dioxide, nitrogen, hydrogen, sulfides, etc.; Some gas fields also contain helium.

Natural gas is an important energy source that is widely used as city gas and industrial fuel; In the 70s, natural gas accounted for about 18 19 of the world's energy consumption. Natural gas is also an important chemical raw material.

Kiss! Hello, happy to answer your <>

Pro, the difference between gas and natural gas: ** Different, coal gas is made of coal and coke through dry distillation or vaporization, Lao Shenjing has many ways to make gas, and the gas produced by different methods is also different. Natural gas, as the name suggests, is a mixture of gases stored in porous rock formations, which is directly extracted by humans and then processed by the necessary processes.

The gas composition is different, and the gas is a mixture of carbon monoxide, methane and hydrogen, and also contains water, oil collection and various impurities. The main component of natural gas is methane, which basically does not contain impurities and is harmless to the human body. But we know that when the concentration of methane in the air is too high, the oxygen in the air will decrease, and it will also make it difficult for people to breathe carefully.
