Why can’t gasoline dispensers have a high flow rate?

Why don’t gas stations have high-flow gasoline dispensers? Today I will lead you to understand the reason why the gasoline dispenser cannot flow at a high flow rate.

The reasonable flow rate range for gasoline dispensers is 40-60 liters/minute. Then why can’t the gasoline dispenser have a high flow rate? This issue is mainly related to the safety and environmental protection of gas stations.

1. Safety hazards at gas stations

1) Fire risk caused by static electricity:

Refueling at a high flow rate will increase the risk of static electricity. When gasoline flows at high speed, static electricity may generate sparks during the refueling process, causing a fire accident.

2) Risk of leakage from the tanker:

Adding fuel at a high flow rate will increase the pressure, which may cause the piping system and joints to break, increasing the risk of leakage, especially at the joints.

3)Difficulties in oil and gas recovery:

High-flow refueling may cause the oil and gas recovery system to be unable to effectively handle large amounts of volatile organic compounds (VOCs), increasing the risk of environmental pollution.

4)Refueling accuracy is reduced:

High-flow refueling may lead to a decrease in refueling accuracy, making it difficult to control the refueling volume accurately, and increasing the possibility that the vehicle’s fuel volume exceeds the standard.

2. Environmental issues caused by the volatilization of gasoline

1)Difficulties in oil and gas recovery:

When gasoline is refueled at a high flow rate, a large amount of volatile organic compounds will be released into the air,

increasing the risk of air pollution. Oil and gas recovery systems may not be able to effectively handle such large amounts of VOCs, resulting in environmental pollution.

2)Loss after oil and gas volatilize:

At high flow rates, gasoline will evaporate more easily during the refueling process, resulting in a loss of oil and gas. Not only does this increase costs, it also hurts the environment.

3)Groundwater pollution risk:

High-flow refueling may increase the risk of leaks in underground storage tanks or pipeline systems, causing gasoline to leak into groundwater and contaminate groundwater resources.

Therefore, gasoline dispensers generally cannot be designed with high flow rates to ensure the safety of the refueling process,

reduce the risk of leakage and environmental pollution, reduce the release of volatile organic compounds,

and reduce the difficulty of oil and gas recovery. This is one of the reasons why environmental regulations limit the flow rate of tankers.

The flow rate of a gasoline refueling machine is between 40-60 liters/minute. The flow rate within this range can meet the refueling needs of general passenger cars, light trucks, and other vehicles, while also ensuring the safety and accuracy of refueling. However, for larger vehicles or where rapid refueling is required, higher flow rates may be required.

It should be noted that too high a flow rate may cause safety hazards and environmental problems. Therefore, when determining a reasonable flow rate, various factors need to be considered comprehensively and relevant regulations and standards must be complied with.
