Background technology

Three-phase product of the present invention, refers to hydrocarbon material hydrogenation reaction product and belongs to gas, liquid, solid three-phase logistics。

Hydrocarbon material hydrogenation reaction of the present invention, refer to hydrogen exist and pressurized conditions under, carbon containing, protium liquid and or solid as oil and or coal occur hydrogenation reaction。

The present invention relates to the hydrogenation process of middle coalite tar raw material hydrocarbon R10F, specifically, it is directed to use with the de-dirt process S1DS of thermal high separation gas of the middle coalite tar of up flow type expanded bed such as suspension bed or the first heat from hydrogenation cracking reaction effluent R10P of its heavy distillat, it is therefore intended that reduce the solid content in hot high score gas S1V。

The present invention relates to the first heat from hydrogenation cracking reaction process R10 of middle coalite tar raw material hydrocarbon R10F and the second follow-up hydrogenation upgrading course of reaction R20。At the first heat from hydrogenation cracking reaction process R10, under hydrogen and the first heat from hydrogenation Cracking catalyst R10C existence condition, carry out the first heat from hydrogenation cracking reaction R10R and obtain the first heat from hydrogenation cracking reaction effluent R10P。

The heavy distillat higher than 350 DEG C of the normal boiling point of middle coalite tar comprises coal tar pitch, its suitable first step method of hydrotreating is the first heat from hydrogenation cracking reaction process R10 using up flow type expanded bed, and following process can supporting second hydrogenation upgrading course of reaction R20 as required。

In the first heat from hydrogenation cracking reaction process R10 using up flow type expanded bed, it is generally impossible to realize 100% entirely convert, because too high heat from hydrogenation cracking conversion per pass can cause low boiling hydrocarbon overcracking fecund gas, high boiling hydrocarbon excessive heat condensation many green cokes charcoal, severe exacerbation product slates, shorten continuous cycle of operation, in other words, in order to utilize raw oil generally to certainly exist thermal cracking recycle oil to greatest extent。In fact, the separation process of the first heat from hydrogenation cracking reaction effluent R10P, the typically at least thermal high separation process S10 that comprises is to isolate major part catalyst and high boiling hydrocarbon component, as required, can also comprising the depressurization step 1DPS and fractional distillation process 1FRAC of hot high score oil, its operational aspects typical is as follows:

1. at thermal high separation process S10, first heat from hydrogenation cracking reaction effluent R10P completes high boiling hydrocarbon component and the relative separation of low boiling hydrocarbon component, obtains the hot high score oil S10L containing solid constituent and the main gas S10V containing solid being made up of hydrogen on volume comprising low boiling hydrocarbon component；

Gas recovery S10V, introduces the second hydrogenation upgrading course of reaction R20 by conventional liquid hydrocarbon lower than 350 DEG C of the normal boiling point contained by it and carries out deep hydrogenation upgrading；

2. at depressurization step 1DPS, the logistics containing solid particle carrying out self-heating high score oil S10L obtains logistics S10L-VLS after blood pressure lowering through decompression device；

3. at fractional distillation process 1FRAC, logistics S10L-VLS after recovery blood pressure lowering, obtain distillate F-LN2, at least some of distillate F-LN2 entrance the second hydrogenation upgrading course of reaction R20 that the main conventional liquid hydrocarbon by normal boiling point lower than 350 DEG C forms；

Logistics S10L-VLS after fractional distillation process 1FRAC, recovery blood pressure lowering, the distillate F-LN3, at least some of distillate F-LN3 that obtain mainly being made up of the conventional liquid hydrocarbon that normal boiling point is 350～540 DEG C return heat from hydrogenation cracking process R10。

The second above-mentioned hydrogenation upgrading course of reaction R20, has two schemes with the flow process relation of the first heat from hydrogenation cracking reaction process R10:

1. one section of flow process and single high-pressure system, the gas S10V containing solid takes off solid (also can simultaneously take off part high boiling component) and becomes to purify high score gas S10VP afterwards, is hydrogenated with upgrading course of reaction R20 in high pressure, hot entrance second；Program flow process is simple, small investment, energy consumption are low；

2. two-stage nitration flow process that is two high-pressure system, the gas S10V containing solid obtains the cold high score oil S30L containing solid constituent and the gas S30-PV being mainly made up of on volume hydrogen after cold anticyclone separating step S30；

Complete de-solid step after cold high score oil S30L blood pressure lowering containing solid constituent and obtain de-solid oil product S70L, de-solid oil product S70L entrance the second hydrogenation upgrading course of reaction R20 after pressurization, heating steps；The program substantially needs to build 2 set high tension units, and flow process is complicated, investment is many, energy consumption high。

In order to realize one section of flow process and single high-pressure system, the existing de-Solid Method containing solid gas S10V is the cyclone separator utilizing centrifugation principle, but has the disadvantage in that

1. owing to the flash gas R10PXV containing solid particle from R10P belongs to saturated vapour phase, inevitable entrained liquids droplet, when in gas S10V containing high viscosity hydrocarbon component, cyclone separator can reduce separation efficiency because of the deposition of combining of the solid formed in runner, heavy hydrocarbon, and long period steady operation difficulty is big；

2. owing to gas R10PXV belongs to saturated vapour phase, inevitable entrained liquids droplet, when in gas S10V containing the solid particle that particle diameter is only small, due to the droplet adhesive attraction to granule, the separation efficiency upper limit of cyclone separator is restricted, sharp separation cannot be realized, namely high score gas S10V falls short of the reality as purge gas, if adopting one section of flow process and single high-pressure system, to cause that the second hydrogenation upgrading course of reaction R20 material solid particles content is high, its consequence is: or cause that the operation cycle is shortened in the reactor catalyst bed blocking using fixing bed, or it is forced to adopt up-flow reactor such as fluidized bed reactor thus increasing investment and operating cost。

Can the single high-pressure system of industrialization longtime running in order to successfully build, the second hydrogenation upgrading course of reaction R20 of the first heat from hydrogenation cracking reaction process R10 and processing purification high score gas S1V that are about to coalite tar heavy distillat in processing forms one section of flow process, it is considered herein that namely the hydrocarbon ils mode of washing that the reliable de-dirt mode of the gas R10PXV containing solid particle is traditional arranges high pressure hydrocarbon oil wash section, based on this conceptual understanding, the present inventor proposes the de-dirt process program of multiple gases R10PXV in succession, and it has been respectively completed patent application, present patent application is one of them technical method。

In order to strengthen the de-dirt effect of gas R10PXV, the present invention proposes the de-dust collecting method of complementary gas that a kind of flow process is simple, energy consumption is extremely low: circulate at least some of liquid R10PXL short circulation washing oil SA as gas R10PXV, by increasing " washing section liquid/gas " volume ratio, the probability of larger fluid contact gas and solid particle thereof strengthens liquid dust removal efficiency, solids content in the hot high score gas S1V of final reduction；In order to other 1 road or 2 roads or multichannel personal cleansing oil wash scheme combination application, short circulation washing section S1A can be used as primary wash process, gas R10PXV becomes short circulation washing gas S1AV after short circulation washing section S1A washs, short circulation washing gas S1AV enters personal cleansing oil wash section and carries out the de-dirt of the degree of depth, and can associated working in a scrubbing tower。

In order to improve gas dust removal efficiency, a kind of effective method is to improve " washing fluid body/gas volume fractions " namely to increase liquid-solid contact probability, therefore, can build at washing process and wash oil circulation loop and namely collect the liquid phase stream existed in the de-dirt section of washing and be then recycled back into the liquid upstream of washing section and constitute circulation washing oil DXR, of course for preventing containing the de-dirt effect of the air stripping that the solid particle backmix effect being recycled back into constituting of solid particle liquid is final, liquid phase stream DXR also should not should not return to the coal addition position of the washing oil of afterbody washing section, and can only the centre position of a certain position before gas R10PXV is converted into S1V and whole washing process。

From Process integration angle, the high pressure hot separator S1E of function singleness has been developed into " flash distillation+scrubbing tower " by the present invention, it is possible to directly mixed heat transfer efficiently, the advantage therefore having simple flow, reducing investment outlay, improve heat recovery rate。

In order to realize the sharp separation of light heavy hydrocarbon component in the first heat from hydrogenation cracking reaction effluent R10P, reduce the normal boiling point in hot high score oil S1LP lower than the content of the hydrocarbon component of setting value such as 350 DEG C to prevent light component excessive heat cracking, can combine and use special air stripping hydrogen heat logistics, now then achieve the integrated further of flow process。In fact, owing to middle coalite tar containing substantial amounts of organic oxygen, organic nitrogen, the hydrotreated product of middle coalite tar contains a large amount of water, ammonia, the water partial pressure of gas phase, ammonia dividing potential drop in last several hydrogenation catalyst beds of hydro-upgrading product quality is particularly determined, it is common to use substantial amounts of recycle hydrogen is as the gaseous phase diluent of water, ammonia components in order to reduce course of reaction。The present invention is equivalent to search out a kind of approach giving full play to its effect for a large amount of circulating hydrogens。

The most important thing is, in order to reduce investment outlay, need that first heat from hydrogenation cracking reaction process R10 and the second hydrogenation upgrading course of reaction R20 using floating bed hydrogenation technology of middle coalite tar heavy oil is constituted online serial operation and be namely combined into a set of high-pressure system, the normal boiling point in the normal boiling point in the coalite tar hydrocarbon component lower than 350～420 DEG C and the first heat from hydrogenation cracking reaction effluent R10P hydrocarbon component lower than 350～420 DEG C in usual second hydrogenation upgrading course of reaction R20 processing, but the reaction temperature of the first heat from hydrogenation cracking reaction process R10 is up to 410～480 DEG C, and the initial reaction temperature only 230～280 DEG C of the second hydrogenation upgrading course of reaction R20, the two temperature gap is up to 160～200 DEG C, clearly, need one reliable temperature of existence to reduce between two reaction zones or energy removes step, the appearance of the present invention meets this requirement, also it is manufactured that fraction washing oil with " doing things by following nature "。

Constituting angle from fractionating system, the present invention has substantially constituted a whole set of high pressure fractionating system, and it is constructed as follows:

1. fractionating column mass transfer section, i.e. scrubbing tower；

The de-mist section of fractionation column top gas, i.e. fractionating column top gas-liquid separation space；

The low liquid phase stay segment of fractionation column, i.e. fractionating column lower liquid phase cushion space；

2. the solidifying cooling system of fractionator overhead air cooling, instant heating high score gas S1V condensing cooling system S3HX turns；

3. fractionator overhead cold reflux can system, the gas-liquid separation part of instant heating high score gas S1V condensing cooling logistics S1VM, it is possible to be tank or the gas-liquid separation zone being combined in miscellaneous equipment, be exactly even S1V condensate cooler S3HX device in space；

Detailed description of the invention

The present invention described in detail below。

Pressure of the present invention, refers to absolute pressure。

Concentration of component of the present invention, when not specializing, is weight concentration and mass concentration。

Conventional gas hydrocarbon of the present invention refers to the hydro carbons under normal condition in gaseous state, including methane, ethane, propane, butane；Conventional liq hydrocarbon of the present invention refers to the hydro carbons being in a liquid state under normal condition, including the hydro carbons that pentane and boiling point thereof are higher；Impurity composition of the present invention refers to hydro-conversion the thing such as water, ammonia, hydrogen sulfide, hydrogen chloride etc. of non-hydrocarbon component in raw oil。

DCL/Direct coal liquefaction process is described below。

DCL/Direct coal liquefaction process of the present invention, refer under solvent naphtha existence condition by being hydrogenated with the method making coal liquefaction, difference according to solvent naphtha and the difference of catalyst, pyrolysis way and hydrogenation mode and the difference of process conditions, it is possible to be divided into following several technique:

1. pyrolysis liquefaction process is dissolved: utilize heavy solvent that pyrolysis of coal extracting can prepare low-ash extract (Japan claims swelling charcoal)；Utilize light solvent extracting at supercritical conditions can obtain the oils based on mink cell focus。This method is without hydrogen, though former process yield is high but product is still solid, and latter technique such as supercritical extraction (extraction) method (SCE) extract content is less high；

2. solvent hydrogenation extracting liquefaction process: if any solvent refined coal process 1 and II (SRC-1 and SRC-II), Exxon donor solvent process EDS, Japan's New Energy Development Organization liquefaction process (NEDOL) etc., using hydrogen, but pressure is less high, solvent naphtha has obvious effect；

3. Hydrogenation method: as the old and new's liquefaction process (IG and New1G) of Germany and the H coal process (H-Coal) etc. of the U.S. broadly fall into this class；

4. coal combines processing method (CO processing) with residual oil: once pass through reactor with residual oil together with coal for solvent naphtha, without recycle oil。Residual oil occurs hydrocracking to be converted into light oil simultaneously。The technique that the U.S., Canada, Germany and the former Soviet Union etc. have nothing in common with each other；

5. dry distilling liquefaction process: the pyrolysis of coal elder generation obtains tar, then carries out hydrocracking and upgrading to tar；

6. underground liquefaction process: solvent is injected subterranean coal, makes coal depolymerization and dissolving, and adding the impulsive force of upper fluid, to make coal collapse scattered, and not consoluet coal is then suspended in solvent, is extracted out by solution with pump and separates processing。

In coal direct liquefaction method, majority belongs to direct hydrogenation liquefaction of coal liquefaction process, no matter which kind of coal faces hydrogen direct liquefaction process, its target is all obtain oil product, and the function of pursuit is all " coal turns oil ", it is necessary to the chemical change existed is " coal hydrogenation ", the common trait of this type of technology is to use solvent naphtha and catalyst at present, the conventional boiling range of solvent naphtha be generally 200～450 DEG C, majority be 200～400 DEG C, solvent naphtha majority is distilled oil, and contained aromatic hydrocarbons majority is the aromatic hydrocarbons of 2～4 ring structures。Therefore, no matter it is which kind of coal faces hydrogen direct liquefaction process, outer oil extraction that it produces or liquefied coal coil (being generally coal liquefaction light oil) or liquefied coal coil modified oil, as long as its composition possesses raw material compositing characteristic of the present invention, all can use the inventive method to be processed。

The thermally dissolving and catalytic of a kind of brown coal preparing liquid fuel that patent CN100547055C states clearly is owned by France in brown coal medium pressure hydrogenation direct liquefaction process, including Coal liquefaction process and liquefied coal coil hydrogenation modification process totally two processes。In order to improve the conversion ratio of coal direct liquefaction and realize coal feedstock entrance reactor, coal is usually made coal dust before entering reactor, being made into coal with the solvent naphtha possessing good hydrogen supply capacity, coal is pressurized, enter reactor after heating。

Coal liquefaction process of the present invention, refer to coal and molecule hydrogen that may be present for raw material, with specific oil product (being generally the hydrogenation modification oil of liquefied coal coil) for hydrogen supply dissolvent oil, under certain operating condition (such as operation temperature, operation pressure, solvent naphtha/coal weight ratio, hydrogen/solvent naphtha volume ratio and suitable hydrogenation catalyst), directly there is the course of reaction of carbon-carbon bond thermal cracking, hydrogenation liquefaction in coal。

Liquefied coal coil of the present invention, refers to the oil product that described Coal liquefaction process produces, and it is present in Coal Liquefaction reaction effluent, is based on the combined reaction product of hydrogen supply dissolvent oil, reaction consumption coal and reaction transfer hydrogen。

After Coal liquefaction process works well, the hydrogenation modification oil that the hydrogen supply dissolvent oil liquefied coal coil that generally employing Coal liquefaction process is self-produced (is generally the conventional boiling range distillate higher than 165 DEG C), the main target of liquefied coal coil hydrogenation modification process is to produce Coal liquefaction process solvent naphtha, specifically improve the content that " there is the component of good hydrogen supply function " in oil product exactly, such as improve cycloalkyl benzene class, the content of bicyclic alkyl benzene class component, the fact that contain a large amount of double ring arene and a large amount of thrcylic aromatic hydrocarbon based on liquefied coal coil, liquefied coal coil hydrogenation modification process is the hydrogenation process of " appropriateness aromatic hydrocarbons is saturated "。

The final goal of Coal liquefaction process is to produce the oil product of outer confession, the hydrogenation modification oil that usual liquefied coal coil hydrogenation modification process produces is divided into two parts: a part is used as Coal liquefaction process hydrogen supply dissolvent oil, and a part is used as the outer oil extraction of coal liquefaction liquefaction process。Generally, at least some of coal liquefaction light oil that Coal liquefaction process produces is used as the outer oil extraction A of coal liquifaction process, remaining liquefied coal coil is used as liquefied coal coil hydrogenation modification process raw oil and produces the oily and outer oil extraction B of Coal liquefaction process hydrogen supply dissolvent, now there is the outer oil extraction of A and B two-way, the final whereabouts of the outer oil extraction of A and B two-way is typically each produce high-quality oil product such as diesel oil distillate, naphtha cut through deep hydrogenation grading process。

Hydrogen supply hydrocarbon described herein, refer to the hydrocarbon component in the high-temperature hydrogenation heat cracking reaction process of low hydrogen content hydrocarbon ils such as residue oil fraction FD4 with hydrogen supply function, hydrogen supply hydrocarbon includes the polycyclic aromatic hydrocarbon of the double ring arene of fractional saturation, fractional saturation, same or like with the kind of the hydrogen supply hydrocarbon of coal liquefaction use and function。In hydrogen supply hydrocarbon, the hydrogen supply speed of dihydro body is all higher than tetrahydrochysene body, and the dihydro body of thrcylic aromatic hydrocarbon is compared with the dihydro body of double ring arene, and it is low that its hydrogen supply speed has height to have；Although test is it has been proved that polycyclic aromatic hydrocarbon is without hydrogen supply capacity, but has the ability of transmission hydrogen。When 400 DEG C, the relative hydrogen supply speed of following component is as follows:

Coal tar and coal tar hydrogenating process are described below。

Coal tar of the present invention, refer to coal tar or its fraction of the process such as pyrolysis step from pyrolysis of coal or coking of coal or the dry distillation of coal or coal generating gas process, can be by-product coalite tar or its fraction of coal generating gas, can also being coal coking pyrolysis of coal process (including semicoke, middle temperature coking, high-temperature coking process) by-product coal tar or its fraction, coal tar of the present invention can also is that the miscella of above-mentioned coal tar。Coal tar of the present invention, including low temperature tar, middle temperature tar, high temperature tar, the different miscella of coal tar, coal tar distillate。

High-temperature coking belongs to coal high temperature pyrolysis process, and the final temperature of pyrolytic process is generally higher than 900 DEG C, generally between 1000～1400 DEG C。Described high temperature coal-tar refers to coal high temperature pyrolysis and produces coke and/or the by-product crude tar oil of town gas process production。High temperature coal-tar is in primary distillation process, generally produce following product: the products such as light oil (topping tar), carbolic oil, naphtalene oil, lightweight washing oil, heavy wash oil, lightweight carbolineum, heavy carbolineum, Colophonium, carbolic oil can be further separated into crude phenols and dephenolize oil, and naphtalene oil can be further separated into thick naphthalene and de-naphtalene oil。High temperature coal-tar light fraction of the present invention refers to: carbolineum, washing oil, naphtalene oil, de-naphtalene oil, carbolic oil, dephenolize oil, light oil and miscella thereof。

Owing to raw coal character and coking or gas-making process condition all change within the specific limits, coal tar oil properties also changes within the specific limits。Process conditions and the product requirement of coal tar primary distillation process also change within the specific limits, therefore the character of coal tar light fraction also changes within the specific limits。The character of coal tar light fraction, proportion is generally 0.92～1.25, normal boiling point is generally 60～500 DEG C and is generally 120～460 DEG C, usual tenor is 5～80PPm, sulfur content is 0.4～0.8%, nitrogen content is 0.6～1.4%, oxygen content is 0.4～9.0%, usual water content is 0.2～5.0%, and carbon residue content is generally 0.5～13%。

Medium temperature coal tar of the present invention, usually comprising conventional boiling range is the mixture that 120～450 DEG C of hydrocarbon components and normal boiling point are higher than 450 DEG C of hydrocarbon components, generally comprise the light fraction FD1 (containing double ring arene fraction) that conventional boiling range is 120～260 DEG C of 10～20%, generally comprise the middle fraction FD2 that conventional boiling range is 260～370 DEG C of 30～40% (containing dicyclo, thrcylic aromatic hydrocarbon fraction), the conventional boiling range comprising the heavy distillat FD3 that conventional boiling range is 370～450 DEG C (containing dicyclo to Fourth Ring aromatic fraction) and 8～20% of 20～35% is higher than the residue oil fraction FD4 (i.e. coal tar pitch fraction) of 450 DEG C。Table 1 is different boiling ranges ends content statistical table in typical case's medium temperature coal tar。

Middle coalite tar, the foreign metal overwhelming majority concentrates on normal boiling point and is especially greater than higher than 350 DEG C in the fraction of 450 DEG C, and generally with easy hydrogenolysis metal component ferrum, calcium, magnesium for key component, usually oil soluble metal compound such as iron naphthenate, calcium naphthenate etc., these easy hydrogenolysis metal components are can quickly to occur hydrogenolysis to be converted into sulfide such as iron sulfide, calcium sulfide at necessarily high temperature and hydrogen existence condition, and granular precipitates or co-precipitation thing can be formed, under certain condition, particle size can be grown up。Experimentation and commercial plant operating all show, in the hydrogenation process of middle coalite tar, raw material different component reaction temperature is substantially consistent with reality according to being divided into following steps from low to high: easily hydrogenolysis metal fever decomposes < high activity condensed-nuclei aromatics thermal condensation and the hydrogenation rudimentary sulphur compound hydrodesulfurization of saturated <, metal-organic complex catalytic hydrogenolysis, rudimentary organic phenol catalytic deoxidation, polycyclic aromatic hydrocarbon takes off carbon residue, said temperature is generally in the range of 170～350 DEG C, it is generally 210～330 DEG C, clearly, this is the reaction temperature interval of a wide scope, light fraction for middle coalite tar should control first for different temperatures section, second, third step is according to carrying out stage by stage from low to high, it is beneficial to reduction metal sulfide formation speed, reduce pyrocondensation compound formation speed, prevent from forming superposition peak value, realize the easy hydrogenolysis metal deposit depth profiles at beds, improve the controllability of deposition reaction。

In usual, the olefin(e) centent of the coalite tar light fraction such as normal boiling point fraction lower than 350 DEG C is high, phenol content is high, gum level is high and contains the more component of easily reaction when mitigation; therefore; the pre-hydrogenation process of described coal tar light fraction; generally use the single dose of hydrogenation protecting agent, olefins hydrogenation agent, hydrogenation deoxidation agent, removal of ccr by hydrotreating agent, hydrogen desulfurization agent etc. or the tandem compound of double; two agent or multi-agent or mixed loading combination, it is common to use down-flow fixed bed hydrogenation reactor。Middle coalite tar light fraction of the present invention oil, refers to normal boiling point and is generally 60～480 DEG C, is generally the coal tar distillate oil of 60～450 DEG C, fixed bed hydrogenation technology generally can be adopted to carry out hydro-upgrading。

The general control principle of the gas-phase presulfiding hydrogen concentration of the hydrogenation process of the present invention described in detail below。

As required, any one supplementary sulfur can be added arbitrary hydrogenation process, but it is typically incorporated into the hydrogenation process entrance of most upstream, to ensure course of reaction necessary minimum concentration of hydrogen sulfide such as 500PPm (v) or 1000PPm (v) or setting, to ensure that the necessary hydrogen sulfide sectional pressure of catalyst is not less than minimum setting。Described supplementary sulfur can be sulfide hydrogen maybe can be converted into hydrogen sulfide to the hydroconversion process material without ill effect, such as hydrogen sulfide containing gas or oil product, or generate Carbon bisulfide or the Methyl disulfide etc. of hydrogen sulfide with high-temperature hydrogen after contacting。When the dilution hydrocarbon of pre-hydrotreating reaction process R1 provides with hydrogen sulfide containing hydrogenation reaction effluent form, if hydrogen sulfide quantity therein meets the needs of pre-hydrotreating reaction process R1, it is possible to not in use by sulfur supplementary agent。

The rule of the high pressure separation process of the hydrogenation reaction effluent of the present invention described in detail below。

The high pressure separation process of hydrogenation reaction effluent generally comprises cold high pressure separator, when hydrocarbon ils density big (such as close with water density) or viscosity is big or when being difficult to separate with water emulsification in hydrogenation reaction effluent, also needing to, operation temperature is set and is generally the high pressure hot separator of 150～450 DEG C, now hydrogenation reaction effluent enters high pressure hot separator and is separated into the hot high score gas gas being mainly made up of hydrogen on volume and a hot high score fluid body being mainly made up of conventional liq hydrocarbon and solid that may be present, hot high score gas entrance operation temperature is generally the cold high pressure separator of 20～80 DEG C and is separated into the oily and cold high score gas of cold high score, owing to a large amount of high boiling components enter in hot high score fluid body, achieve following target: cold high score oil density diminishes or viscosity diminishes or is easily isolated with water。The high pressure separation process of hydrogenation reaction effluent arranges high pressure hot separator, is also equipped with reducing the advantage of thermal loss, because hot high score fluid body can avoid the process that cools using air cooler or water cooler that hot high score gas experiences。Simultaneously, it is possible to the hydrogenation process that hot for part high score fluid body returns upstream recycles, to improve the overall raw material character of the hydrogenation process receiving this recycle oil, or this recycle oil is circulated hydrogenation。

Before hydrogenation reaction effluent or hot high score gas enter cold anticyclone separate section, generally first reduce temperature (being usually and reactive moieties charging heat exchange) extremely about 220～100 DEG C (this temperature should be higher than that sulfur hydrogenation ammonia crystallization temperature in this hydrogenation reaction effluent gas phase), then inject washings generally wherein and form water filling back end hydrogenation reaction effluent, washings are used for absorbing ammonia and issuable other impurity such as hydrogen chloride etc., and the aqueous solution after absorbing ammonia necessarily absorbs hydrogen sulfide。In cold anticyclone separate section, described water filling back end hydrogenation reaction effluent is separated into: the cold high score gas being mainly made up of hydrogen on volume, the cold high score oil being mainly made up of conventional liq hydrocarbon and dissolved hydrogen, a cold high score water that is that be mainly made up of water and that be dissolved with ammonia, hydrogen sulfide。Described cold high score water, wherein the content of ammonia is generally 0.5～15% (w), it is desirable to be 1～8% (w)。One purpose of note washings is the ammonia in absorption hydrogenation reaction effluent and hydrogen sulfide, it is prevented that forms sulfur hydrogenation ammonia or many sulfur ammonia Crystallization Plugging heat exchanger channel, increases system pressure drop。The injection rate of described washings, should determine according to following principle: on the one hand, and washings are divided into vapour phase water and liquid phase water after injecting hydrogenation reaction effluent, and the liquid phase water yield have to be larger than zero, it is desirable to for the 30% or more of washings total amount；Another further aspect, washings are for absorbing the ammonia in hydrogenation reaction effluent, it is prevented that the ammonia density of high score gas is too high, reduce catalyst activity, the ammonia volumetric concentration of usual high score gas is more low more good, is generally no greater than 200PPm (v), it is desirable to be not more than 50PPm (v)。Described cold high pressure separator operation pressure is that hydrogenation reaction partial pressure deducts actual pressure and drops, the difference of cold anticyclone separate section operation pressure and hydrogenation reaction pressure, unsuitable too low or too high, is generally 0.35～3.2MPa, is generally 0.5～1.5MPa。The hydrogen volume concentration value of described cold high score gas, should not too low (cause device operation pressure rise), generally should be not less than 70% (v), 80% (v) should be not less than, be preferably not below 85% (v)。As previously mentioned at least some of, be generally the cold high score gas of 85～100% and be returned in hydrogenation reaction part and recycle, to provide the necessary amounts of hydrogen of hydrogenation reaction part and hydrogen concentration；In order to improve plant investment efficiency, it is necessary to assure recycle hydrogen concentration is not less than aforesaid low limit value, for this, according to concrete feedstock property, reaction condition, product slates, it is possible to get rid of a part of described cold high score gas with get rid of reaction produce methane, ethane。Cold high score gas for discharge, it is possible to adopt conventional membrane separation process or pressure swing adsorption technique or oil wash technique to realize hydrogen and non-hydrogen gas Component seperation, and the hydrogen reclaimed is used as new hydrogen。

New hydrogen enters and adds the hydrogen that hydrogen partial consumes with supplementary hydrogenation process, and new hydrogen hydrogen concentration is more high more good, generally should not lower than 95% (v), it is desirable to be not less than 99% (v)。All new hydrogen can be introduced arbitrary hydrogenation reaction part, it is desirable to introduce pre-hydrotreating reaction process R1。
