Description
Technical field
This utility model is related to Investigation of Petroleum Vapor Recovery Technology field, more particularly to a kind of new gas recovery system for oil.
Background technology
Oil and products thereof is the mixture of multiple Hydrocarbon, and wherein vapour pressure is higher at normal temperatures for light component, pole
Volatile, therefore produce to oil depot in the whole storage and transport process of gas station from refinery in oil product, it is widely present oil evaporation damage
The problem of consumption.Oil product evaporating loss brings many serious harms to enterprise and society, such as reduces oil quality, environmental pollution, money
Source wastes, causes disaster hidden-trouble and harm personal safety etc..Therefore oil vapour is carried out reclaiming imperative, two petroleum vapor recoveries
Device is then indispensable conveyance system facility in Petroleum Production, accumulating and transport.
Currently, national departments concerned increasingly payes attention to the improvement to oil vapour pollution and the enforcement of Investigation of Petroleum Vapor Recovery Technology, and will
Which combines the important process as recycling economy with clean manufacturing, the utilization of resources, qualified discharge.Strengthen promoting by making laws
Dynamics, has just continuously promulgated multiple with the execution standards and norms for forcing effect for only 2007.Such as：《Storage tank farm atmospheric pollution
Thing discharge standard》(GB20950-2007)、《Gasoline transports atmosphere pollutants emission standardses》(GB20951-2007)、《Gas station
Atmosphere pollutants emission standardses》(GB20952-2007)、《Product oil management of wholesale enterprises technical specification》(SB/T10446-
2007)、《Product oil storage enterprise management technique specification》(SB/T10445-2007)、《Product oil retailer management technique rule
Model》(SB/T10390-2007)、《Gas recovery system for oil engineering technology directive/guide》(Q/SH0117-20070、《Environmental impact assessment skill
Art directive/guide》(HJ/T2.2-2007)、《Oil depot, gas station's air contaminant treatment project acceptance inspection inspection specifications》(HJ/T431-
2008) etc., especially promulgated by Environmental Protection Department and State Administration for Quality Supervision and Inspection and Quarantine's joint in 2015《Petroleum refining
Emission of industrial pollutants standard》(GB31570-2015), VOC emission standard is put forward higher requirement.
The external research work for having started to Investigation of Petroleum Vapor Recovery Technology from the sixties in 20th century, has the oil of multiple maturations at present
Gas recovery technology.In the technical field, China falls behind foreign countries more than 20 years, in order to improve the research water of China's Investigation of Petroleum Vapor Recovery Technology
Flat, accelerate the localization process of advanced device for recovering oil and gas, need the advanced technology for constantly using for reference and absorbing developed country, improve
The research of itself and production capacity.Internal and international at present conventional Investigation of Petroleum Vapor Recovery Technology includes following several classes, has his own strong points
Also there is its drawback.
1st, direct combustion gasses recovery technology
Directly combustion method is a kind of method using thermal oxidation technique process evaporation oil gas (organic exhaust gas), its principle be by
The gas containing hydrocarbon direct oxidation burning produced in storage and transport process, after the carbon dioxide of generation of burning, water and air are as process
Purification gas are directly discharged.The technological process is only used as a kind for the treatment of measures of control exhaust of oil, but can not reclaim oil product, because
Without economic benefit.
2nd, condensed oil-gas recovery technology
Method of the condensation method device for recovering oil and gas typically using multistage continuous coo1ing oil gas is made reducing the temperature of Volatile Gas
Cohesion reclaimed for liquid, its step is typically realized by pre-cooling, mechanical refrigeration, liquid nitrogen refrigerating etc..Now petroleum vapor recovery
Rate is up to 99%.
3rd, adsorb Investigation of Petroleum Vapor Recovery Technology
Adsorption separation technology in every profession and trade is widely used and is developed over nearest twenty or thirty year, becomes a kind of
Particularly important gas separation.Absorption method separates and recovers the principle comparative maturity of oil gas, and adsorption separation process is using mixed
The strong and weak difference of adhesion between each component and adsorbent in compound, makes hardly possible absorption skill detached with easy absorbed component in mixture
Art.
Activated carbon adsorption can make the concentration of oil gas vent be down to very low standard, and assimilation effect is relatively good, but is because
The inlet concentration of oil gas is larger, is adsorbed as exothermic reaction, once there is active carbon bed temperature runaway, pipeline is connected with entrucking trestle work again
Connect, be likely to result in security incident.Therefore Tokyo, Japan regulations of rules, gas concentration >=1vol%, prohibits the use of combustibility
Acticarbon, in Japan prohibits the use of membrane separation process and active carbon adsorption Investigation of Petroleum Vapor Recovery Technology.
4th, thin film selected area update strategy recovery technology
Oil vapour and the membrance separation of air Mixture be according to different gas at various speeds, due to diffusibility with molten
Difference between Xie Du, using polymeric membrane to gasoline component in oil gas preferentially through the characteristics of, allow the mixed of gasoline component/air
Gas is closed in the case where certain pressure reduction is promoted, technique is relatively easy, but initial investment is costly.
5th, Investigation of Petroleum Vapor Recovery Technology is absorbed
Absorption process is the difference using mixed gas dissolubility in a solvent, realizes that by solution absorption oil gas oil gas is returned
The technology of receipts.The general absorbent sprayed using oil gas and from absorption tower top carries out counter current contacting, and absorbent enters to hydrocarbon component
Row selective absorbing, unabsorbed gases are discharged through spark arrester.At present, absorption process generally uses 3 kinds of different absorbent, i.e.,
Light diesel fuel, low temp. gasline and organic solvent.
The above-mentioned five kinds of Investigation of Petroleum Vapor Recovery Technology of Investigation of Petroleum Vapor Recovery Technology (device) Integrated comparative, are more generally adopted at present in the world
It is absorption process, absorption method and condensation method, membrane separation process application is fewer, only has application in the minority such as Germany area.Because of oil gas
Concentration is big, and possesses larger recovery value, and exhaust emission standard is high, is therefore only difficult to realize row up to standard by above-mentioned single technique
Put.
