How to effectively reduce the volatile consumption of oil in large oil storage tanks

Due to the volatility of oil products, the volatile consumption of oil products is inevitable in the storage process of large oil storage tanks. The volatilization of oil causes both economic losses and pollution to the environment. Especially in the open air environment, large-scale oil storage tanks in the petrochemical industry will continue to accumulate energy under the exposure of the sun, causing their surface and interior to heat up rapidly, causing sun overheating, and accelerating the volatilization of oil consumption. How to effectively reduce the volatilization consumption of large oil storage tanks?

1. Strengthen the inspection and maintenance of oil storage tanks
Regularly check the sealing condition of the oil storage tank, and check and maintain the important accessory equipment, such as: breathing valve, safety valve, oil meter and other important accessory devices, to ensure good sealing performance.

2. Strictly control the temperature in the oil storage tank
Because the higher the temperature in the oil storage tank, the stronger the activity of oil molecules and the greater the volatilization consumption of the oil. Therefore, the temperature in the oil storage tank must be reduced as much as possible. It is possible to reduce the temperature of direct sunlight by painting anticorrosive coatings with good light reflectivity such as white. It is also possible to use spray equipment to wash the top and wall of the tank with water flow to reduce the volatilization consumption of the oil in the oil storage tank.

3. Oil storage tank with floating roof structure
The floating roof in the oil storage tank can effectively reduce the volatilization consumption of oil, because the gas space on the oil liquid surface in the floating roof storage tank is very small, the exhaust volume is low, and the breathing loss is very small, which can reduce the oil storage tank. The volatilization loss caused by the big and small breath.

In addition to the above three methods, a baffle can also be installed under the breathing valve joint pipe of the oil storage tank to avoid direct impact of the air inhaled into the oil tank on the large concentration layer on the oil surface, and reduce the reversal exhalation after the oil is sent. Reduce the concentration of oil and gas in the next exhalation, thereby reducing the volatilization consumption of oil in the oil storage tank.
