Description

Hollow fiber tubular membrane oil and gas treatment system with catalytic combustion furnace and its method

The invention relates to a hollow fiber tubular membrane oil gas treatment system with a catalytic combustion furnace and its method, especially when a kind of oil gas becomes a purified gas after adsorption, its efficiency can reach 97% or even more than 99%, and it can improve The treatment performance of dense oil gas and re-oxidation decomposition is suitable for gas stations, underground oil storage tanks or similar areas.

At present, gas stations will volatilize oil and gas during the refueling process for automobiles and motorcycles. 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 All are equipped with a pressure valve and a breathing tube. When the pressure generated by the oil and gas is greater than the value set by the pressure valve, the pressure valve will be closed and discharged into the air through the breathing tube, allowing the pressure generated by the oil and gas in the underground oil tank to return to the air. to a 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.

However, the oil and gas discharged from the underground oil tank through the breathing tube can easily have a huge impact on the environment. In addition to polluting the surrounding air, there will be safety hazards and dangers when the concentration of the oil and gas discharged from the breathing tube is too high.
