What gas should I add to the car gas station?

Automobile filling stations are filled with compressed natural gas, liquefied natural gas and so on.

As a fuel for heaters and vehicles, it is increasingly replacing chlorofluorocarbons as aerosol propellants and refrigerants to reduce the damage to the ozone layer.

Liquefied petroleum gas is a mixture of propane and butane, usually accompanied by a small amount of propylene and butene. Ethylmercaptan is a strong odor agent. When added to liquefied petroleum gas, the leakage of liquefied petroleum gas can be easily found. Liquefied petroleum gas (LPG) is the gas produced in the process of crude oil refining or the gas volatilized in the process of oil or natural gas exploitation.

Liquefied petroleum gas will liquefy at room temperature and 6 atmospheres, so it can be loaded into pressure cylinders. Usually, LPG only fills 85% of its capacity, which can leave room for gas expansion when the cylinder is heated. The expansion ratio of liquefied petroleum gas is about 250: 1.

Safety precautions for gas stations:?

1. During filling operation, pay attention to whether there is any leakage of vehicle-mounted gas cylinders, and hang up safety hooks to prevent mechanical damage caused by bursting rings.

2. When adding liquid, pay attention to the leakage of muzzle and bottle valve, and wear protective helmet and gloves to prevent frostbite.

3. When unloading liquid, pay attention to the pressure of the container and tank car, connect the electrostatic grounding device, and pad the wooden board under the wheel to prevent the vehicle from slipping, crushing the unloading pipeline and causing liquid leakage.

4. During routine maintenance inspection, observe whether there is air leakage or liquid leakage in the pipeline, and wear protective equipment. During maintenance, exhaust the gas or liquid in the pipeline for maintenance.

5. When the air compressor is running, pay attention to the blowdown of the air compressor to prevent the water in the instrument wind from freezing the valve and causing leakage.

6. When there is a lot of leakage in the tank farm, wear protective overalls and oxygen cylinders before operation to avoid suffocation, frostbite and poisoning. 7. Fireworks are strictly prohibited in the gas station, and mobile phones are used.

8, refueling operations, passengers in the car must get off to a safe place to wait, it is forbidden to manned refueling in the car.

9. During normal operation, if air or liquid leakage is found during inspection, the nearby valve shall be closed immediately and the pressure relief valve shall be opened. After the pressure in the pipeline is released, it will be put into maintenance. Maintenance under pressure is prohibited.

10. In case of vehicle fire, liquid filling machine leakage, tank car leakage, pipeline leakage and other abnormal situations in the station, the personnel should immediately call for help and press the nearest emergency stop button.
