Description

A kind of processing fuel oil VOC containing steamsCondensation adsorption catalytic oxidizing equipment and method
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 It is not able to satisfy the demand in market, the development and application for meeting technique is in the ascendant.Oil gas adsorption recovery technology is always domestic and international One research topic of concern, the performance of oil gas adsorbent influence the cost of investment, operating cost and peace of entire recovery technology Full performance.The adsorbent for being presently available for petroleum vapor recovery is mainly active carbon class, silica type and zeolite molecular sieve class, various absorption All there are some problems in agent, such as the deterioration problem of adsorbent, active carbon thermal coefficient is low, have combustibility, activated carbon fibre valence 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.
