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 technology
There are serious energy loss, energy loss not only to be had an impact to surrounding enviroment in crude oil storage and transport process, 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 of the big breathing of storage tank and small breathing discharge（Hydrocarbons pollutant）.It refers to that oil tank is received to call out suction and put
When hair oil operates, to environmental emission volatile organic matter（Non-methane total hydrocarbons）Process, small breathing discharge then refers to oil product in oil tank
During quiet ratio storage, the process of non-methane hydrocarbon emission is caused due to the variation of temperature.
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, 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 air under sunlight, 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 breathing problem, and inflammable and explosive, easily lead to fire and explosion when high concentration is discharged；Part
VOCs can also destroy ozone layer.
Petrochemical enterprise Frequent Accidents in recent years, accident cause huge personnel and economic loss, also result in greatly
Social influence.Since there is VOCs specific high volatile and uncontrollable discharge form, leakage can not with the naked eye perceive, because
This can usually cause ill effect once leakage accident occurs.
