Description
Technical field
The utility model relates to the hybrid system of a kind of hydrogen and hydrocarbon ils, is specifically applicable in the fixed bed reactors of hydrocarbon oil hydrogenation.
Background technology
Along with the quickening of diesel oil of vehicle trend in world wide, the demand of future diesel will increase further.But, containing the harmful substance that oxysulfide (SOX), nitrogen oxide (NOX) and particle (PM) etc. are a large amount of in the waste gas discharged after diesel combustion.These materials not only form the acid rain in city and outskirts area, destroy the ozone layer of the earth, also may cause human carcinogen.For this reason, diesel oil standard increasingly stringent in world wide, the low-sulfur of production environment close friend or ultra-low-sulphur diesel have become the problem of countries in the world government and oil refining enterprise's most attention.European Union member countries came into effect Europe V discharge standard from 2009, and the developed country such as the U.S., Japan has also promulgated respective vapour, diesel product index.China has also come into effect state III standard being equivalent to EuropeⅢ emission standard from 2010, come into effect the local vapour product index of state V discharge standard in Beijing, and diesel oil is also about to implement state V discharge standard.
The hydrotreating techniques that current production meets Europe IV, the vapour of Euro V emissions, diesel oil adopt is mostly trickle bed hydrogenation reactor, and the gas phase namely in reactor is continuous phase, liquid phase surround by gas-phase space and exist with the form of drop or liquid film.Research shows, in trickle bed reactor, hydrogen is from gas phase diffusion and the speed be dissolved into oil is the rate-determining steps of whole hydrogenation reaction.Traditional trickle bed reaction adopts one of reason of higher hydrogen-oil ratio to be exactly strengthen gas-liquid mass transfer, accelerates the dissolving of hydrogen, thus improves the reaction rate of hydrodesulfurization, denitrification reaction.In addition, hydrogenation reaction is a strong exothermal reaction, in order to maintain reaction bed temperature, needs to utilize a large amount of excessive hydrogens to take away the heat of reaction generation by beds.Therefore, the initial volume of hydrogen and feedstock oil larger (standard state hydrogen to oil volume ratio is generally 4 ~ 8 times of chemical hydrogen consumption amount) in traditional trickle bed hydrogenation technique reactant.These excessive hydrogen not participating in chemical reaction need constantly to recycle, and this just causes the investment cost of hydro-refining unit and running cost to increase substantially.
In order to solve the problem that hydrogen circulates in a large number, starting consideration and utilizing hydrocarbon ils to be hydrogenation process hydrogen supply as molten hydrogen medium.Its principle is pre-mixed feedstock oil and hydrogen, and hydrogen is dissolved in hydrocarbon ils, and the hydrogen by dissolving in hydrocarbon ils is hydrogenation reaction hydrogen supply.But the amount of the hydrogen dissolved in hydrocarbon ils is less, be not enough to the demand meeting hydrogenation reaction, therefore in prior art, have employed a general method, reactor outlet stream portions is circulated, together mix with raw material, hydrogen, making it to dissolve hydrogen, is hydrogenation reaction hydrogen supply.But a large amount of product circulations will cause energy consumption to increase.
US6428686 discloses and can be extracted out by hydrocarbon ils in the middle part of reactor, after fully mixing, hydrocarbon ils Returning reactor is continued reaction with hydrogen.This makes feedstock oil and diluent repeatedly fully to mix with hydrogen, and hydrocarbon ils can dissolve more hydrogen, and the method can process the larger feedstock oil of chemical hydrogen consumption, has widened the range of application of this technique.But the equipment that device mixes outward and operating process more complicated.
Utility model content
The purpose of this utility model is to provide the hybrid system of a kind of hydrogen and hydrocarbon ils, solves in the hydrocarbon oil hydrogenation treatment process process of no hydrogen circulation, the problem that hydrogen and hydrocarbon ils mix in reactor.
The hybrid system of the hydrogen that the utility model provides and hydrocarbon ils is, described hybrid system is arranged between two beds of fixed bed reactors, hydrocarbon ils manifold trunk 2, blender 3, flowline 4 and liquid distributor 5 is set gradually along reactor axial direction, wherein hydrocarbon ils manifold trunk is connected with the bottom of a upper beds 1, and hydrocarbon ils effuser 8 and air inlet pipe 9 are set on hydrocarbon ils manifold trunk, the reactor shell below blender 3 sets out tracheae 10.
For the hydrocarbon oil hydrogenation treatment technology of no hydrogen circulation, in reactor the combined amount of hydrogen and hydrocarbon ils and hybrid position very important, if hydrogen is mixed into too much, then the excessive hydrogen consumption that causes of hydrogen is high, if hydrogen mixed volume is too low, or it is improper that hybrid position is selected, then product quality can be caused to decline or catalysqt deactivation.In order to solve the problem, the utility model adopts between bed and arranges hybrid system, and described hydrocarbon ils manifold trunk is connected with the bottom of a upper beds 1, makes to be flow through from hydrocarbon ils manifold trunk 2 by the logistics of beds 1.And hydrocarbon ils effuser 8 is set on hydrocarbon ils manifold trunk 2.Described hydrocarbon ils effuser 8 arranges flow control valve, the outflow of hydrocarbon ils can be controlled.Flowing out the molten hydrogen amount of hydrocarbon ils by detecting, determining the flow being mixed into hydrogen needed in hydrogen between this bed and hydrocarbon ils hybrid system.
The entrance of described air inlet pipe 9 is arranged on the position above hydrocarbon ils manifold trunk 2 and blender 3 junction.From air inlet pipe 9, the hydrogen needing to be mixed into is introduced blender 3.
Arrange in described blender 3 and can make hydrogen and the well-mixed inner member of hydrocarbon ils.
Described flowline 4 one end is connected with blender 3, and the other end is connected with liquid distributor 5, and the logistics flowing through blender 3 all flows through flowline 4, and enters liquid distributor 5, then flows out from liquid distributor 5.
Reactor shell below blender 3 sets out tracheae 10.Preferably, the outlet of described escape pipe 10 is arranged on the reactor shell between blender 3 and liquid distributor 5.
Described escape pipe 10 arranges voltage-controlled valve.Regulated the flow of discharging gas in reactor by this voltage-controlled valve, regulate the pressure of reactor beds interlayer, thus ensure next beds 7 all the time can cover by hydrocarbon ils.
That is, under the normal state run, next beds 7 has hydrocarbon ils cover layer 6, and described liquid distributor 5 is arranged on the top of described hydrocarbon ils cover layer 6.
Advantage of the present utility model:
1, the utility model is built in the reactor of fixed bed, compared with external blender, does not need to bear the pressure differential of high-pressure medium and the outer air of blender, does not therefore need blocked up wall, overall investment cost and operating cost low.
