Gas storage and distribution station and gate station, what is a gas gate station

1.How is the footprint and size of the storage and distribution station determined? (Does it have anything to do with the size of the gas supply?) If so, what is the specific relationship? )

2.When setting up storage and distribution stations, should there be enough safety distance from surrounding buildings? Can it be located in an urban area?

3.If the scale of gas supply is large, the unevenness coefficient is large, and the peak regulation is insufficient, can multiple storage and distribution stations be set up in the same town?

4.Is there a safe distance between the storage and distribution station and the door station, and can the two be set together?

The city gas gate station is a receiving station for natural gas to enter the urban pipeline network from the long-distance pipeline, and it is also an urban distribution station, which has the functions of detection, filtration, metering, pressure regulation, heat tracing, odorization, distribution and remote telemetry and remote control.

City gate stations can take thermal insulation and heat mixing measures. The city gate station can choose different structural forms according to the needs of users. The system of the city gate station is standard, and the main and auxiliary regulators are all products of international famous brands.

Other parts are domestic high-quality products, to achieve high quality, high reliability, high precision work.

The city gate station can be equipped with imported flow meters and flow computers, and can also be equipped with domestic high-quality flow meters. The city gate station can have the functions of automatic cut-off and automatic release of ultra-high and low pressure at the same time. The city gate station can work in a remote telemetry and remote control mode.

Gate station refers to the metering and receiving station after the long-distance pipeline is sent to a certain place, generally as the terminal refueling station of a certain place, refers to the station of refueling vehicles, and is divided into the refueling station of refueling private cars, passenger cars, buses or taxis and the refueling station that refuels the operation (CNG pry car).

Storage and distribution stations are generally stations with storage functions, such as storage tanks, peak shaving containers, etc., and storage and distribution stations are generally built in places that cannot be reached by long-distance pipelines or as peak shaving functions.

The station refers to the place where the source of gas is natural gas, which is generally the source of the pipeline network or the place where natural gas is stored.

Natural gas or oil, gasoline and other substances are basically the same. Let's put it simply:

LNG is transported through the pipeline through the gate station, because the pipeline is long, the pressure regulating station or the booster station is needed to improve the power of liquid flow in the transportation process, and it reaches the end of the pipeline and the end station, because the user demand is not constant, and the pipeline transportation can not be large and small, it is necessary to set up a storage space, that is, the storage and distribution station, because the pressure of the LNG is higher and cannot be directly used by the user, it needs to be transported through the storage station or transported to the gasification station for gasification, after gasification, if a certain distance is still required, The pressure of the gas is still high, and the pressure has been regulated by the multi-stage pressure regulating station, and the natural gas after pressure regulation is supplied to the user.

Then the oil is basically this process, and the transportation mode can be pipelines, cars, trains, ships, etc., and there is no problem of pressurization in the middle of cars and trains, so there is no pressure regulating station.

That's pretty much it.

City gate station refers to the gas pressure regulating and metering facility located at the junction of long-distance gas transmission pipeline and city gas transmission and distribution system, referred to as city gate station. The storage and distribution station is mainly used for the storage of natural gas, and then the distribution of natural gas by the company's internal gas department. The gasification station is mainly to gasify the liquefied natural gas and turn it into a gaseous state.

The pressure regulating station is to regulate the pressure of natural gas and then transport it to downstream users. The relationship between these stations is that they exist with each other and that this natural gas is transported.

Knowledge points: gas engineering. The gas storage and distribution station is mainly composed of auxiliary facilities such as pressure transmission equipment, storage and cracking bucket storage devices, gas pipelines and control instruments, and fire-fighting facilities.

Summary. The differences between a gas ** station and a gas supply station are as follows:1

The gas station refers to the place of production and gas production, usually referring to the production base of the city gas company; A gas supply station is a refueling station that supplies gas to vehicles. 2.The gas station mainly produces and produces city gas, including natural gas, liquefied petroleum gas, etc.; The gas supply station mainly provides vehicle gas, including natural gas, liquefied petroleum gas, etc.

3.Gas** stations are usually fixed production bases and do not change their location at will; Gas supply stations can be set up in different locations as needed. 4.

The scale of the gas ** station is large and requires a lot of equipment and human resources to maintain; Gas stations, on the other hand, are smaller and usually require only a few staff.

The differences between the coal trap and the gas supply station are as follows:1The gas station refers to the place of production and gas production, usually referring to the production base of the city gas company; A gas supply station is a refueling station that supplies gas to vehicles.

2.The gas station mainly produces and produces city gas, including natural gas, liquefied petroleum gas, etc.; The gas supply station mainly provides vehicle gas, including natural gas, liquefied petroleum gas, etc. 3.

Gas** stations are usually fixed production bases and do not change their location at will; The gas supply station can be set up in different locations according to the need. 4.The scale of the gas ** station is large and requires a lot of equipment and human resources to maintain; Gas stations, on the other hand, are smaller and usually only require a few workers.

There is a gas filling station in Sha Tin, and I want to take a bottle to inflate it myself.

This Bohe Gas** station and gas supply station Zen do not usually provide gas filling services, they mainly provide gas** services for industry, commerce and households. If you need an inflatable service, you can look for a specialized inflatable station or gas station. So you can't just go to the inflat.

The types of services are not the same.

The gas station cannot inflate individuals because、1.Safety issues: There may be potential safety hazards in personal inflation, such as improper operation, use of unqualified gas cylinders, etc., which can easily cause fire, ** and other accidents.

2.Restrictions on laws and regulations: According to relevant laws and regulations, gas stations can only provide inflatable services to units or individuals with corresponding qualifications, so as to ensure the safety and legality of inflatable fiber.

3.Insurance liability: For the purpose of insurance liability and risk control, the gas station will generally only provide gas filling services to units or individuals with corresponding qualifications to ensure the safety and legitimacy of gas filling.

4.Business strategy: Towngas stations may choose not to provide chain inflating services to individuals according to their own business strategies to ensure the stability and efficiency of their operations.

There are inflatable ones there.

Gas flushing can be carried out at a gas company or at a special filling station. Generally speaking, the gas company will provide the service of flushing the gas, and the gas filling station can also provide a similar service Hengsui.

This needs to be found in your location depending on the actual situation.
