Anesthetic effect on the central nervous system/stimulation effect on the skin and mucous membranes/delipidation effect, which makes the intracellular lipid balance disorder, causing dermatitis and eczema./Long-term exposure to benzene vapor can induce symptoms such as leukemia, chromosomal abnormalities and abnormal hematopoietic functions.
Waste energy
The gasoline loss is estimated according to the category A area, excluding the loading and transportation loss of the oil tanker (all according to the railway tank car and the automobile tank car), and the transportation loss and the barrel filling loss are not included. Oil storage tanks are all counted as floating roof tanks, and gas station storage tanks are all counted as concealed tanks; once railway loading, railway transportation (<500km) once, railway unloading once (floating roof tank), floating roof tank storage, automobile tanker One loading, one transportation by tanker road (<50km), one unloading at a tanker gas station, storage of oil tanks at a gas station, and a retail fuel dispenser. The estimated total loss is: railway tank car loading loss rate + railway transportation loss rate + railway unloading loss rate (floating roof tank) + floating roof tank storage loss rate + automobile tank car loading loss rate + automobile tank truck transportation loss rate + automobile tank unloading rate Loss rate (other tanks) + storage loss rate of gas station storage tanks + retail loss rate (fuel dispensers) = 0.17% + 0.16% + 0.01% + 0.01% + 0.10% + 0.01% + 0.23% + 0.01% + 0.29% = 0.99% ≈ 1%
Polluted environment
Pollution to the atmospheric environment (urban photochemical smog)/pollution to underground soil and water sources.
Affect oil quality
Take gasoline as an example. With the evaporation of light components, the initial boiling point and 10% point of gasoline increase, the vapor pressure decreases, and the starting performance deteriorates; the octane number decreases, and the evaporation temperature also rises. When gasoline burns in the engine The anti-knock performance deteriorates, accelerates gasoline oxidation, and increases gasoline gum; when the evaporative loss rate of aviation gasoline reaches 1.2%, the initial boiling point increases by 3°C, the vapor pressure decreases by 20%, and the octane number decreases by 0.5 units.
Affect safety in production
Gasoline and other light oils have the characteristics of being volatile, flammable, leaking, and easy to accumulate static charges. They are extremely prone to explosion or fire accidents, causing significant loss of life and property.
