At present, gas stations will volatilize oil and gas during the refueling process for automobiles and motorcycles. However, the current practice is to bury the oil vapor recovery pipeline in the fuel dispenser under the fuel dispenser, and the other end of the oil vapor recovery pipeline in the fuel dispenser is connected to the underground The oil tank is connected, and through the vacuum-assisted oil vapor recovery equipment, the volatilized oil vapor during the refueling process is collected into the lower oil tank through the oil vapor recovery pipeline in the tanker to achieve the purpose of oil vapor collection.

However, the above-mentioned oil and gas are transported to the underground oil tank, and the oil in the underground oil tank will still volatilize oil and gas when it is stored, and after a period of storage, the oil and gas in the underground oil tank will gradually generate pressure. Therefore, the underground oil tank Both are equipped with pressure valves and breathing pipes. When the pressure generated by the oil and gas is greater than the value set by the pressure valve, the pressure valve will be opened and discharged into the air through the breathing pipe, allowing the pressure generated by the oil and gas in the underground oil tank to return to the air. Safe value to avoid danger. In addition, in the oil company's gasoline and diesel tank trucks or large oil storage tanks for gasoline and diesel loaded trains, exhaust gas is produced during the process of loading and unloading oil. The exhaust gas contains very dense volatile organic gases, and the concentration can be as high as 60g/ Nm3, 300g/Nm3 or higher.
