Description
Technical field
The present invention relates to environmental technology field, especially a kind of processing fuel oil VOC containing steamsCondensation adsorption be catalyzed oxygen
Change device and method.
Background technique
Crude oil, gasoline and naphtha are fuel oil common in petrochemical industry, in transport, storage, produce and use
Easy evaporating loss in journey, it is mainly carbon four, light dydrocarbon and carbon six in organic exhaust gas i.e. VOCs that the oil gas evaporated, which is also known as, and there are also few
Carbon one, carbon two, carbon three and the carbon seven of amount.According to statistics, for gasoline from the oil gas that oil tank evaporates, organic solvent volume score is high
Up to 30% or so.Naphtha is similar with gasoline physico-chemical property, especially light naphthar, and boiling range is 70 DEG C~145 DEG C, some refinings
The light naphthar of factory is also eager to excel than gasoline volatility.Crude oil and crude oil place of production oil tank, such as the South Pars crude oil in the Middle East, light component
Content is high, and volatility and gasoline are very nearly the same.
It is Chinese every year because the petroleum resources of storage, the misuse of transport facilities are up to tons up to a million, this not only waste of resource, Er Qiezao
At environmental disruption;The oil gas overflowed simultaneously easily reaches explosion limit after mixing with air, to cause the safety accidents such as fire.Cause
This needs administers the petroleum resources of volatilization, and one kind is recovery technology, and another kind of is destruction technology.Recovery technology is mainly wrapped
Include the technologies such as condensation, absorption and sorption and UF membrane.The volatile organic matter of recycling can be directly or through returning after simple purification
Technical process recycles, to reduce the consumption of raw material.Destruction technology mainly includes high temperature incineration, catalysis burning, biological oxidation, low
Isothermal plasma destroys and the technologies such as photochemical catalytic oxidation.
Condensation method petroleum vapor recovery is to utilize the vapor partial pressure power of hydrocarbons at different temperatures poor, using mechanical refrigeration skill
Art mostly uses polynary working medium overlapping to reduce oil gas temperature step by step, and hydrocarbons vapor partial pressure is made to reach saturation state, and gradually cold
Congeal into a kind of oil-gas recovery method of liquid.Foreign countries begin to the research work of Investigation of Petroleum Vapor Recovery Technology early in the middle of last century, until
More than 400 condensation method oil-gas recovery devices, Chinese Zhenghai refining in 1989 are installed in the whole world by Margaret Edwards company of the U.S. in 1997
Oily factory introduces the condensation method oil-gas recovery device of a set of the said firm's manufacture, is safely operated so far, remarkable in economical benefits;TaiWan, China
Existing 24 large and medium-sized oil depots all apply condensation method oil-gas recovery device.Condensation method Investigation of Petroleum Vapor Recovery Technology is usually according to oil
Gas composition, the rate of recovery and exhaust emission standard determine the minimum temperature setting of condensing unit, and the efficient process that condenses is using multistage
Cooling, end-o f-pipe -control concentration be -110 DEG C can meet GB20950-2007 " storage tank farm atmosphere pollutants emission standards " and
(non-methane hydrocarbon emission limit value 25g/m3, goes the national standards such as GB20952-2007 " gas station's atmosphere pollutants emission standards "
Except efficiency >=95).With the raising of national emission standard and the requirement of oil vapor treatment equipment energy consumption, single processing technique is

Lattice are high, packing volume is big, and silica gel water imbibition is strong etc., need to screen or develop the Special adsorbent for being suitable for petroleum vapor recovery thus.
Catalytic oxidation technologies are applied in the fine chemistry industry of petrochemical industry middle and lower reaches than wide, since crude oil gasoline naphtha etc. is waved
The oil-gas component issued contains a small amount of carbon one, carbon two and carbon three, the especially presence of carbon two, the characteristics of being not easily recycled,
So that qualified discharge (120mg/m3) huge to recovery technology pressure.Catalytic oxidation technologies are made in pernicious gas using catalyst
Combustible component oxygenolysis at a lower temperature purification method.CnHm and organic molten Ji steam oxidation are decomposed and generated
CO2And H2O simultaneously releases heat.Its reaction equation are as follows:
As VOCs discharge standard is lower and lower, it is ensured that final exhaust emissions concentration meets " petroleum refining industry pollutant
Discharge standard " GB 31570-2015 and " petro chemical industry pollutant emission standard " GB 31571-2015 requirement (non-first
Alkane total hydrocarbon emissions limit value 25g/m3, removal efficiency >=95), the high-concentration organic waste gas such as crude oil gasoline naphtha are used alone
Condensation technology, absorption techniques adsorption technology are difficult to accomplish qualified discharge, destroy technology and require strictly volatile organic matter concentration,
And heating power oxidation technology temperature is excessively high, and has open fire.Catalytic oxidation technologies are lower with respect to initiation temperature, and the flames of anger generates, relatively
Heating power oxidation technology is more safer.It in the VOCs containing steam such as crude oil gasoline naphtha, is easily crystallized containing steam, and containing not
The light component easily recycled such as carbon two, the general single organic media pressure of qualified discharge pressure ratio are big.It is suitable for using condensation adsorption
The processing of catalysis oxidation coupling technique, wherein condensation process controls two-way awkward silence at a meeting using single compressor, recycles organic solvent in VOCs
90% or more, VOCs concentration is further decreased by adsorption technology, reduces the load of catalysis oxidation, last catalytic oxidation technologies
The light component being not easily recycled such as carbon two is decomposed into CO2And H2O realizes qualified discharge.
