How to avoid an explosion in API standard 650 self-anchored storage tanks

Avoiding the explosion of the API standard 650 self-anchored storage tank destroys the formation of explosive conditions by controlling the entry of oxygen. According to the conditions of combustion and explosion of combustibles, it is known that in order to avoid fire and explosion accidents in the oil storage tank, it is necessary to prohibit oxygen or air from entering the oil storage tank.

For large-capacity internal floating roof API standard 650 self-anchored storage tanks, the mixed operation mode of payment can be implemented to make the floating plate float in a small range, reducing the chance of exposure of ferrous sulfide in the space below the floating plate and contact with the air; high liquid level operation is adopted, reduce the gas phase space of the API standard 650 self-anchored storage tank and reduce the corrosion range; adopt the method of inert gas replacement (nitrogen protection), which can realize oxygen-free operation and prevent the formation of explosive mixed gas; when the API standard 650 self-anchored storage tank is filled with oil, inject steam or nitrogen, etc. Protective measures, after the injection of steam is stopped, nitrogen should be injected in time to prevent air from entering the API standard 650 self-anchored storage tank.
