What is the natural gas to compressed natural gas conversion ratio?

Compressed natural gas (25MPa) is about 1 250 of the volume of natural gas of the same mass in the standard state.

The pressure of piped natural gas for general household use is 2000kpa.

The low-pressure pipeline natural gas to the home, because the general residential natural gas cooker is rated at 2000pa, and there are factors such as the pressure drop of the pipeline, the general pipeline pressure is adjusted to 3000pa. (One atmosphere.)

is 100,000 pascals). The natural gas pipelines of the municipal pipeline network are also divided into high pressure and medium pressure, etc., and there is a specific range of pressure levels.

In China, the pressure range of urban pipe networks: 005-0 .

4MPa, after adjusting the pressure to 2-3kpa (generally 2.).8kpa) into the pre-stove pipe; The rated outlet pressure of the natural gas stove is 2kpa, once the pressure regulator fails or other reasons make 005-0 .

The pressure of 4MPa is connected to the low-pressure gas pipeline, which will cause the natural gas stove to leak because it cannot withstand this high pressure, and the danger may occur in serious cases.

According to different applications, there are many of them, and the civil stove is about 2kpa, and the long-distance transmission can be as high as 10mpa

Upstairs 2000kpa I'm afraid it's not making people laugh to death, the copy is not clear, your gas supply is 2mpa, and your stove is not special equipment.

The pressure is different for different applications, and it is meaningless not to specify the application problem, only examples.

Civilian 2 3kpa, above 2000kpa, I'm afraid it's not going to die of laughter, and the layman can't copy it blindly.

The medium pressure gas supply of urban gas is 10kpa

The long-distance output can reach more than 10MPa.

Compressed natural gas tens of MPa is also common.

You deleted the first sentence, 2000kpa is 2mpa, which is higher than the gas of high-pressure pipelines.

Under normal circumstances, the pressure of natural gas in domestic pipelines is 2000kpa.

Usually the pressure of liquefied petroleum gas is there, while the pressure of natural gas is there, and the pressure of artificial gas is there. However, the pressure of natural gas in various places is different, but it will be in a permissible range, and those with cryptorex body can learn more about the natural gas in each region.

Introduction of natural gas

Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gas field gas, mud volcanic gas, coalbed methane, and biogenerated gas, etc.).

The long-term common definition of "natural gas" is a narrow definition from the perspective of energy, which refers to a mixture of hydrocarbon and non-hydrocarbon gases naturally contained in the formation. In petroleum geology, it usually refers to oilfield gas and gas field gas. Its composition is dominated by hydrocarbons and contains non-hydrocarbon gases.

It is mainly composed of methane (85%) and small amounts of ethane (9%), propane (3%), nitrogen (2%) and butane (1%). It is mainly used as a fuel, and is also used as a raw material for the manufacture of chemicals such as acetaldehyde, acetylene, ammonia, carbon black, ethanol, formaldehyde, hydrocarbon fuels, hydrogenated oil, methanol, nitric acid, syngas and vinyl chloride.

Natural gas is compressed into a liquid for storage and transportation. Coal miners, nitric acid makers, power plant workers, organic chemical synthesizers, gas users, petroleum refiners, etc. may come into contact with this product.

Summary. Hello, it is a pleasure to serve you: it is necessary to know the pressure of CNG (compressed natural gas), let's say 20MPa

1 cubic meter of CNG (compressed natural gas) is a natural day under the standard condition of 200 cubic meters.

The calculation is as follows:

Let it be an ideal gas, pv=k

20MPa 1 cubic meter = standard condition refers to 1 atmosphere pressure, that is, under the air pressure) solution v = 200 cubic meters.

What is the conversion ratio between Natural Gas and CNG (Compressed Natural Gas)?

Hello, very high failure Qixing for your service: need to know the pressure of CNG (compressed natural gas), assuming that 20MPa1 cubic meter CNG (compressed natural gas) is 200 cubic meters of standard conditions to guess the slippery natural day. The calculation is as follows:

Let it be an ideal gas, PV = K20MPa 1 cubic meter = standard condition refers to 1 ear under atmospheric pressure, that is, under the air pressure) solution to obtain v = 200 cubic meters.

In other words, 200 cubic meters of pipeline gas can be compressed into 1 cubic meter of CNG Yes, dear.

Impossible. The conversion ratio between LNG and CNG is approximately 1.

Liquefied natural gas (LNG) and compressed natural gas (CNG) are mainly composed of methane, and gaseous methane is 625 times the volume of liquid methane. LNG is about 1 625 of the volume of natural gas of the same mass in the standard state. Compressed natural gas (25MPa) is about 1 250 of the volume of natural gas of the same mass in the standard state.

1 625) (1 250) = conversion ratio to CNG is approximate: 1

Reach. Article 1 of China's current "Town Gas Design Code" GB50028 divides urban gas pipelines into seven levels according to the gas design pressure P (unit: MPA).

1. High-pressure gas pipeline Class A: the pressure is less than P and less than or equal to.

2. Grade B of high-pressure gas pipeline: the pressure is less than P and less than or equal to.

3. Sub-high pressure gas pipeline Class A: the pressure is less than P and less than or equal to.

4. Sub-high pressure gas pipeline class B: the pressure is less than P and less than or equal to.

5. Medium pressure gas pipeline class A: the pressure is less than P and less than or equal to.

6. Medium pressure gas pipeline grade B: the pressure is less than P and less than or equal to.

7. Low-pressure gas pipeline: the pressure is less than p.

Precautions for using natural gas:

It is recommended to install a gas leak alarm because natural gas is colorless and odorless, unlike coal gas, which is difficult for us to detect once a natural gas leak occurs.

Do not place the natural gas equipment in the bedroom, keep the room where the gas equipment is installed, and in addition, the gas pipeline should not be darkened, which is not conducive to flushing and maintenance.

Doors and windows should be well ventilated. Due to good ventilation, once there are harmful gases such as natural gas and carbon monoxide indoors, they can be discharged outdoors in time, thus eliminating the risk factors of ** poisoning.

Frequent inspection, frequent maintenance, often check whether the natural gas pipeline, meter, stove, water heater connecting hose, etc. are fixed firmly, whether there is any gas leakage point, such as shouting socks to find problems in time to notify repair, can not be used reluctantly.

It is forbidden to stack flammable materials around natural gas stoves and meters. <>

The pressure unit of coal gas and natural gas is not the same, so it needs to go through a certain conversion before it can be compared.

The unit of pressure commonly used for coal gas is millimeters of water (mmh2o), while the unit of pressure used for natural gas is usually measured in kilopascals (kpa). When converting the gas pressure to the natural gas pressure, it can be calculated using the following formula:

Natural gas pressure = gas pressure

For example, if the pressure of coal gas is 500 mmH2O, the formula for converting it to natural gas pressure is:

Natural gas pressure = 500 mmH2O = 49 kPa It should be noted that in actual use, the pressure of coal gas and natural gas should also consider the factors such as the diameter of the pipeline, length, material and flow rate to determine the correct use pressure.
