Description
Technical field
The invention belongs to crude oil storaging and transport technology fields, and in particular to a kind of collection defeated station volatile organic compounds recovery system
System and method.
Background technique
There is serious energy loss in crude oil storage and transport process, energy loss not only has an impact surrounding enviroment, but also right
The safety of tank field also has larger impact.Under nominal situation, oil gas volatilization amount is related with form of export.On oil tank, there is oil transferring
Calling out under operation inhales form of export and the quiet small breathing form of export than under storage.Discharge exhaust emission owner in 4th area of oil storage tank
Refer to the volatile organic matter (hydrocarbons pollutant) of the big breathing of storage tank with small breathing discharge.It calls out suction and puts and refer to that oil tank is received
When hair oil operates, to the process of environmental emission volatile organic matter (non-methane total hydrocarbons), small breathing discharge then refers to oil product in oil tank
It is quiet than during storage, due to temperature variation and cause the process of non-methane hydrocarbon emission.
Oil field oil gathering station, the arch-roof tank of multi-purpose station oil storage, floating roof tank at present, because of the volatility of big breathing and small breathing discharge
Organic matter does not collect recycling, first is that exhaust emission is caused, second is that energy loss is caused to waste.
Volatile organic matter includes the substances such as hydro carbons, aromatic hydrocarbons, alcohols, aldehydes, ketone, lipid, amine, organic acid,
Photochemical reaction occurs with the nitrogen oxides in atmosphere under sunlight irradiation, generates the photochemistry such as ozone, peroxide nitro acyl, aldehydes
Smog causes secondary pollution, stimulates the eyes and respiratory system of people, endangers the health of people；Most of VOCs is toxic, has evil
It is smelly, it can make one to suffer from accumulation property respiratory disease, and inflammable and explosive, easily lead to fire and explosion in high concentration discharge；Part
