The danger of crude oil storage tank is mainly from the danger of the crude oil and the cause of the fire accident.
An analysis of the risk of crude oil
Crude oil is a B class of flammable liquids, flammable and explosive limit is narrower, but the value is low, explosion has a certain risk, while crude oil is easy to Feiyi, special attention should be paid to the fire fighting work.
Analysis of the causes of two fire and explosion accidents
The characteristics of crude oil determine that the risk of fire and explosion is the most important and most important risk factor for large crude oil storage tanks. The three necessary conditions for a fire accident are the fire, the combustibles and the air.
The problem of the fire source is mainly solved by strengthening management, and the fire source is forbidden to be brought to the storage area.
Combustibles and air
The leaked crude oil is exposed to the air, which constitutes a combustible. The oil spill, more frequent in storage and transportation, the main oil tank oil run run run, dehydration, equipment, pipeline, valve damage caused by poor sealing and running oil, volatile oil and gas, there is also a possibility of tank rupture, welding and other large floating plate bottom leakage accident.
Corrosion is one of the most important factors for leakage. There have been oil leakage accidents caused by the bottom corrosion of oil tanks at home and abroad.
