Implement optimal morphology of the present invention
Below, explanation is about the suitable embodiment of the method for refining of oil of the present invention with reference to the accompanying drawings.But the present invention has more than and is limited to each following embodiment, for example makes up aptly between the integrant of these embodiment and also can.
[the 1st embodiment]
Fig. 1 is the processing flow chart of the 1st embodiment that is used to illustrate the method for refining of oil of the present invention, especially express as stock oil use heavy crude, produce gas turbine fuel (GTF) simultaneously by it and contact the processing flow chart of the occasion of decomposing the raw material of using (HCR) with the raw material or the hydrogenation decomposition of (FCC) with flowing.
Stock oil as process object has no particular limits, hydrocarbon-type oil from crude oil to the mink cell focus all may be suitable for, to being applicable to mink cell focus, especially API degree such as オ リ ノ コ one Le in the occasion of the mink cell focus below 20, the example that the yield of the petroleum products that value added is high significantly improves is illustrated.
The API degree is the index of dividing quasi-oil with physical behavior, as shown in the formula like that, is the numerical value of deriving according to its proportion.Proportion when S represents 60 ° of Fahrenheits.
API＝(141.5/S)-131.5
In this routine method, be stock oil, at first, stock oil delivered to fractionation by distillation operation 1, handled with in the past same distillation by carrying out, be separated into the distilled oil M1 that constitutes by lower boiling oil and the irreducible oil M2 higher than its boiling point with such heavy crude.As the device that distills processing, can use well as the topping plant (ト Star パ one) of general atmospheric distillation plant, but if the fractionation by distillation means then have no particular limits.Again, not distinguishing distilled oil, to distill recovery also passable without exception, and it is also passable that distilled oil is divided into multiple recovery according to boiling point.Dividing into the multiple occasion that reclaims, then as shown in arrow 11 such if resulting distilled oil satisfies the specification of oil composition, also can omit on by-pass line ground as the hydrogenation refinery operation 2 of subsequent processing.
Secondly, at least a portion of the distilled oil M1 that will obtain in fractionation by distillation operation 1 is delivered to hydrogenation refinery operation (HT operation) 2, carries out in the presence of hydrogen and catalyzer that hydrogenation refinery is handled, desulfurization, obtains hydrogenation refinery oily M3, M3 '.
Hydrogenation refinery as distilled oil M1 is handled, in distilled oil M1, mix hydrogen, import in the reactor that is filled with CoMo catalyzer or NiMo catalyzer, after the sulphur composition that under the condition of High Pressure Hydrogen distilled oil M1 is contained and nitrogen component carried out hydro-desulfurization, denitrogenation, separating hydrogen gas obtained hydrogenation refinery oil M3, M3 ' in high-pressure separator.
Different with hydrogenation refinery operation 2, will deliver to solvent deasphalting operation (SDA operation) 3 at the irreducible oil M2 that fractionation by distillation operation 1 obtains, handle deasphalted oil (DAO) M4 and asphaltene (pitch) M5 that obtains as extracting solution by solvent deasphalting.
Handle as this solvent deasphalting, at first, be separated into the asphaltene (pitch) that deasphalted oil, metal and residual carbon are concentrated in solvent extraction tower by irreducible oil M2 is contacted with the solvent convection current.Deasphalted oil is reclaimed with solvent from top of tower, obtains by separating the solvent of removing in the regenerant in supercritical state.Asphaltene (pitch) reclaims with solvent from tower bottom, makes the solvent evaporation in the regenerant and removes.
Usually know that the solvent deasphalting operation as the extraction yield of the sulphur that contains in the asphaltene oil with respect to the extract oil of base feed oil, vanadium, nitrogen, residual carbon etc., is different for every kind of composition.For the present invention, in the occasion of the irreducible oil that obtains with the fractionation by distillation heavy raw oil as raw material, with with respect to the vanadium concentration in the deasphalted oil of the content of vanadium in the stock oil as extraction yield, at stock oil is that the occasion of air distillation irreducible oil is preferably below 20%, occasion at the underpressure distillation irreducible oil is preferably below 15%.No matter, all do not have the lower limit of extraction yield, can select the scope that suits according to the kind of the stock oil of being supplied with, vanadium concentration etc. for any occasion.Again, in the occasion of the irreducible oil that obtains with the low-sulfur stock oil of fractionation by distillation sulphur concentration below 2.0wt% as raw material, vanadium concentration in the deasphalted oil is preferably below the 25wtppm in the occasion of air distillation irreducible oil, is preferably below the 70wtppm in the occasion of underpressure distillation irreducible oil.
The present invention is in above-mentioned each occasion, and the extraction rate reached that just can make the solvent deasphalting operation under the situation of the load that the hydrogenation demetalization-desulfurization process to the back segment of solvent deasphalting operation does not strengthen can obtain refining oil to the limit expeditiously.
The refining procedure of solvent deasphalting operation 3 back segments only is the occasion of hydrogenation demetalization-desulfurization process 4, wish solvent deasphalting operation 3 control extraction yields, making the vanadium among the deasphalted oil M4 that obtains is below 20% with respect to the extraction yield of the vanadium (V) among the base feed irreducible oil M2.
At least a portion of the deasphalted oil M4 that will be obtained by solvent deasphalting operation 3 is delivered to hydrogenation demetalization-desulfurization process (HDMS operation) 4, carries out hydrogenation demetalization-desulfurization and handle and obtain through the HDMS of over hydrogenation demetalization-desulfurizing and refining refining oil M6 in the presence of hydrogen and catalyzer.Handle about this hydrogenation demetalization-desulfurization, substantially the same with above-mentioned hydrogenation refinery processing (hydrogenation refinery operation 2), therefore omit explanation.
For handle the HDMS refining oil M6 that obtains by such hydrogenation demetalization-desulfurization, wish to select demetalization-desulfurization condition to make its vanadium (V) concentration below 2wtppm, be preferably in below the 1wtppm, make simultaneously its sulphur concentration at 0.5wt% to be preferably in below the 0.3wt%.
Again, at least a portion of the hydrogenation refinery oil M3 that the part of the HDMS refining oil M6 that will obtain at hydrogenation demetalization-desulfurization process 4 and hydrogenation refinery operation 2 obtain is delivered to the 1st mixed processes 5 and is mixed, and obtains petroleum products.
In the occasion of the petroleum products that the 1st mixed processes 5 is obtained, set mixing condition and make its vanadium (V) concentration below 0.5wtppm as gas turbine fuel (GTF).At this moment, for example if the V concentration of HDMS refining oil M6 is 1wtppm, then the V concentration of hydrogenation refinery oil M3 is decided to be 0wtppm, the volume ratio of HDMS refining oil M6 and hydrogenation refinery oil M3 is mixed into 1: 1 or below it (promptly reducing the side of HDMS refining oil M6).
For the nubbin of not supplying with the 1st mixed processes 5 among the HDMS refining oil M6 that obtains at hydrogenation demetalization-desulfurization process 4, it is decomposed the raw material of using (HCR) with the raw material or the hydrogenation decomposition of (FCC), petroleum products in the middle of making as mobile contact again.For the nubbin of not supplying with the 1st mixed processes 5 among the hydrogenation refinery oil M3, also can be made into the petroleum products M3 ' of petroleum naphtha (raw gasline), gasoline, light coal wet goods again.
Method of refining according to such oil, because at least a portion of hydrogenation refinery oil M3 is mixed mutually with the part of HDMS refining oil M6, so for example can access the enough low petroleum products of vanadium (V) concentration of gas turbine fuel etc. thus, again, by the nubbin of HDMS refining oil M6 can obtain metal concentration (V+Ni) lower, decompose with (FCC) or hydrogenation as the contact of flowing and to decompose middle petroleum products with the raw material of (HCR), can the high multiple petroleum products of while production value added expeditiously.
Again, for decompose the middle petroleum products that decomposes the raw material of using (HCR) with the raw material or the hydrogenation of (FCC) as mobile contact, compare with gas turbine fuel (GTF) etc., permissible concentration height to metal, therefore under the situation of the load of not following hydrogenation demetalization-desulfurization, the yield of the deasphalted oil M4 of solvent deasphalting operation 3 can be improved, by-product amount can be suppressed thus from asphaltene (pitch) M5 of irreducible oil M2.
Again, in treatment scheme shown in Figure 1, metal concentration and the sulphur concentration of the deasphalted oil M4 that obtains in solvent deasphalting operation 3 are lower, mix with the part of the lower HDMS refining oil of metal concentration and sulphur concentration and satisfy to flow contact and decompose the occasion of decomposing the raw material proterties of using (HCR) with (FCC) or hydrogenation, its part is not being delivered under the situation of hydrogenation demetalization-desulfurization process 4, mix with the part of HDMS refining oil M6 by the by-pass line shown in the symbol among Fig. 1 12, become the contact of flowing and decompose with (FCC) or hydrogenation decomposition also passable with the middle petroleum products of the raw material of (HCR).
[the 2nd embodiment]
Fig. 2 is the treatment scheme of the 2nd embodiment that is used to illustrate the method for refining of oil of the present invention, in the method, the same with the 1st embodiment shown in Figure 1, produce gas turbine fuel (GTF) simultaneously from stock oil and decompose the raw material of using (HCR) with the raw material or the hydrogenation decomposition of (FCC) with flowing to contact.
The main difference point of the 2nd embodiment and the 1st embodiment shown in Figure 1 is: be provided with that the HDMS refining oil M6 that will obtain carries out that underpressure distillation is handled and the underpressure distillation separation circuit 6 that is separated into decompression light oil M7 and decompression irreducible oil M8 at the back segment of hydrogenation demetalization-desulfurization process 4.That is, the method for refining of oil shown in Figure 2, the HDMS refining oil M6 that will similarly obtain with example shown in Figure 1 delivers to underpressure distillation separation circuit 6, carries out the underpressure distillation separating treatment.
In this underpressure distillation is handled, HDMS refining oil M6 is imported vacuum still to be distilled, separate low boiling point component and high boiling point composition among the HDMS refining oil M6, obtain lower boiling decompression light oil M7, obtain high boiling decompression irreducible oil M8 from tower bottom from top of tower.
Handle in order to carry out such underpressure distillation, in this example, for handle the asphaltene oil M4 that obtains by above-mentioned solvent deasphalting, wish that the vanadium among the resulting deasphalted oil M4 is controlled at below 30% with respect to the extraction yield of the vanadium (V) among the base feed irreducible oil M2.Thus, in the hydrogenation demetalization of back segment and desulfurization are handled, do not apply big burden, just can improve the rate of recovery of petroleum products.
Again, for handling resulting HDMS refining oil M6 by such deasphalted oil M4 being carried out hydrogenation demetalization-desulfurization, wish to select demetalization-desulfurization condition make its vanadium (V) concentration below the 20wtppm, be preferably in below the 10wtppm, make simultaneously sulphur concentration below the 0.5wt%, be preferably in below the 0.3wt%.
Moreover, handle resulting decompression light oil for such HDMS refining oil M6 is carried out underpressure distillation, make its vanadium concentration below 1wtppm for well.
Through after such operation, at least a portion of the oily M3 of hydrogenation refinery that at least a portion of the decompression light oil M7 that underpressure distillation operation 6 is obtained and hydrogenation refinery operation 2 obtain is delivered to the 2nd mixed processes 7 and is mixed mutually, obtains one of petroleum products.
In the occasion of the petroleum products that the 2nd mixed processes 7 is obtained as gas turbine fuel (GTF), the same with example shown in Figure 1, make its vanadium (V) concentration below 0.5wtppm.At this moment, the same with previous example, adjust ratio of mixture aptly according to the V concentration of decompression light oil M7.In the occasion of vanadium (V) concentration below 0.5wtppm of decompression light oil M7, do not add hydrogenation refinery oil M3 and directly former state ground is also passable as gas turbine fuel (GTF) again.
Handle the decompression irreducible oil M8 that obtains and the nubbin of not supplying with underpressure distillation separation circuit 6 among the HDMS refining oil M6 for the nubbin of decompression light oil M7 with through underpressure distillation, they are decomposed the raw material of using (HCR), petroleum products in the middle made from the raw material or the hydrogenation of (FCC) individually or by mixing aptly as mobile contact decomposition.
Method of refining according to such oil, by underpressure distillation separation circuit 6 HDMS refining oil M6 being carried out underpressure distillation handles, boiling spread by the distillation proterties is separated into the decompression light oil M7 and decompression irreducible oil M8 that contains metal and residual carbon hardly, therefore vanadium concentration, metal concentration and the residual carbon that can allow HDMS refining oil M6 itself are to higher concentration, can improve the yield of the deasphalted oil M4 of solvent deasphalting operation 3 thus, therefore can suppress by-product amount from asphaltene (pitch) M5 of irreducible oil M2.
Again, for the deasphalted oil M4 that obtains in solvent deasphalting operation 3, in enough low occasions such as their vanadium (V) concentration, its part is not delivered to hydrogenation demetalization-desulfurization process 4 and just import by-pass line 12, mix with decompression irreducible oil M8, be made as the contact decomposition of flowing and decompose with the intermediates of the raw material of (HCR) also passable with (FCC), hydrogenation from underpressure distillation separation circuit 6; Again, for the HDMS refining oil M6 that obtains at hydrogenation demetalization-desulfurization process 4, import bypass pipe 12 and mix mutually, being made as the contact of flowing and decomposing that to decompose the middle petroleum products of the raw material of using (HCR) with (FCC), hydrogenation also passable with decompression irreducible oil M8 from underpressure distillation separation circuit 6.
[the 3rd embodiment]
Fig. 3 is for the treatment scheme of the 3rd embodiment of the present invention is described, this method is the same with example shown in Figure 1, is produced gas turbine fuel (GTF) simultaneously and is flowed contact to decompose with (FCC) or hydrogenation by stock oil and decompose the raw material of using (HCR).
The main difference point of the 3rd embodiment and the 1st embodiment shown in Figure 1 is: be provided with after fractionation by distillation operation 1 the irreducible oil M2 that obtains is carried out that underpressure distillation is handled and the underpressure distillation separation circuit 20 that is separated into decompression light oil M11 and decompression irreducible oil M12, the decompression irreducible oil M12 that obtains is carried out solvent deasphalting handle the solvent deasphalting operation 21 that is separated into deasphalted oil M13 and asphaltene (pitch) M14, and the mixing oil of the deasphalted oil M13 that obtains and decompression light oil M11 is carried out hydrogenation demetalization-desulfurization handle the hydrogenation demetalization-desulfurization process 22 that obtains HDMS refining oil M15.
That is, in the method for refining of oil shown in Figure 3, the irreducible oil M2 that will obtain with example shown in Figure 1 delivers to underpressure distillation separation circuit 20 and carries out the underpressure distillation processing the samely.
In this underpressure distillation separating treatment, irreducible oil M2 is imported vacuum still to be distilled, separate low boiler cut and high boiling fraction among the irreducible oil M2, from top of tower obtain low boiling point component decompression light oil M11, obtain high boiling decompression irreducible oil M12 from tower bottom.
After underpressure distillation separation circuit 20, the decompression irreducible oil M12 that obtains is delivered to solvent deasphalting operation 21, be separated into deasphalted oil M13 and asphaltene (pitch) M14.Handle for this solvent deasphalting, the same with example illustrated in figures 1 and 2, but metal and residual carbon and sulphur content have concentrated than irreducible oil M2, therefore for handling the deasphalted oil M13 that obtains by the solvent deasphalting of decompression irreducible oil, the ideal higher limit step-down of the extraction yield of vanadium (V) is preferably controlled and is made that extraction yield is 15%.
Secondly, the deasphalted oil M13 that obtains is like this mixed with above-mentioned decompression light oil M11, obtain HDMS refining oil M15 by this mixing oil being carried out hydrogenation demetalization-desulfurization processing.For the HDMS refining oil M15 that obtains, wish to select demetalization-desulfurization condition, make its vanadium (V) concentration below the 2wtppm, be preferably in below the 1wtppm, make its sulphur concentration be 0.5wtppm, be preferably in below the 0.3wtppm simultaneously.
Then, at least a portion of the hydrogenation refinery oil M3 that the part of the HDMS refining oil M15 that d hydrogenation demetalization-desulphurisation treater preface 22 is obtained and d hydrogenation refinery operation 2 obtain is delivered to the 3rd mixed processes 23 and is mixed, and obtains the gas turbine fuel as petroleum products one of (GTF) of vanadium concentration below 0.5wtppm.
For the nubbin of not supplying with the 3rd mixed processes 23 among the HDMS refining oil M15 that obtains in hydrogenation demetalization-desulphurisation treater preface 22, it can be contacted as flowing to decompose and use (FCC) or hydrogenation decomposition with the raw material of (HCR), make middle petroleum products.
The concentration of the metal ingredient that deasphalted oil M13 and decompression light oil M11 contain respectively, residual carbon, sulphur composition is difference widely, be pressed with the very occasion of big difference at reaction conditions especially hydrogen branch, they are not mixed, just carrying out hydrogenation demetalization-desulfurization with optimal conditions respectively in reactor separately handles, at least a portion of the decompression light oil M11 that mixes then or hydrogenation demetalization-desulfurization has been handled is mixed with at least a portion of the oily M3 of hydrogenation refinery, can access the gas turbine fuel (GTF) of its vanadium (V) concentration below 0.5wtppm.
Method of refining according to such oil, owing to the part of HDMS refining oil M15 is mixed with at least a portion of hydrogenation refinery oil M3 at the 3rd mixed processes 23, therefore vanadium (V) concentration of the mixing oil that obtains is enough low, can access the gas turbine fuel as one of petroleum products.Again, even handle the nubbin that obtains HDMS refining oil M15 through over hydrogenation demetalization-desulfurization from the mixing oil of will reduce pressure light oil M11 and deasphalted oil M13, also can access metal concentration (V+Ni) low, as the contact of flowing decompose with or hydrogenation decompose the middle petroleum products of the raw material of usefulness, the high multiple petroleum products of production value added simultaneously expeditiously.
For decompose the middle petroleum products that decomposes the raw material of using (HCR) with (FCC) or hydrogenation as mobile contact, compare with gas turbine fuel etc., permissible concentration height to metal, therefore use or the raw material of hydrogenation decomposition usefulness with flowing contact to decompose by producing gas turbine fuel (GTF) simultaneously, the yield of the deasphalted oil M13 of solvent deasphalting operation 21 can be improved, by-product amount can be suppressed thus from the asphaltene (pitch) 14 of decompression irreducible oil M12.
Secondly, the 4th embodiment～the 6th embodiment that suits as the occasion of stock oil to sweet crude oil be described.So-called in this manual sweet crude oil comprises Arabic light oil, Iranian light oil, Iranian Marvin's mink cell focus and sulphur concentration and their equal or lower crude oil, refers to the crude oil of sulphur concentration below 2.0wt% particularly.
In following embodiment, owing to use sweet crude oil, compare with the 1st embodiment that with the mink cell focus is object, omitted hydrogenation refinery operation (HT operation) 2.Content is in addition carried out the processing same with the 1st embodiment basically.Below, for the operation identical, attach the symbol that adds A after the symbol in the 1st embodiment and describe with the 1st embodiment.
[the 4th embodiment]
Fig. 4 is the schema of expression the 4th embodiment of the present invention.In the 4th embodiment,, at first, stock oil is delivered to fractionation by distillation operation 1A carry out distillation processing the same as before as stock oil with above-mentioned sweet crude oil, be separated into the distilled oil M1A and the high irreducible oil M2A of Bi Qi boiling point that constitute by lower boiling oil.Install get final product identical with the 1st embodiment.
The distilled oil M1A that obtains at fractionation by distillation operation 1A is separated into distilled oil M3A and M3A ' by flasher 30.
The irreducible oil M2A that obtains at fractionation by distillation operation 1A delivers to solvent deasphalting operation (SDA operation) 3A, handles deasphalted oil (DAO) M4A and asphaltene (pitch) M5A that obtains as extracting solution by solvent deasphalting.
Handle as this solvent deasphalting, at first, contact with the solvent convection current, be separated into the asphaltene (pitch) that deasphalted oil, metal and residual carbon are concentrated by make irreducible oil M2A at solvent extraction tower.Deasphalted oil is reclaimed with solvent from cat head, obtains by separating the solvent of removing in the regenerant in supercritical state.Asphaltene (pitch) reclaims with solvent from tower bottom, makes the solvent evaporation in the regenerant and removes.
The refining procedure of solvent deasphalting operation 3A back segment only is the occasion of hydrogenation demetalization-desulfurization process 4A, and the extraction yield that the control solvent deasphalting is handled is advisable vanadium (V) concentration of deasphalted oil M4A below 25wtppm.
At least a portion of the deasphalted oil M4A that will be obtained by solvent deasphalting operation 3A is delivered to hydrogenation demetalization-desulfurization process (HDMS) 4A, in the presence of hydrogen and catalyzer, carry out hydrogenation demetalization-desulfurization handle obtain hydrogenation demetalization-desulfurizing and refining HDMS refining oil M6A.This hydrogenation demetalization-desulfurization is handled substantially the same with the above-mentioned hydrogenation refinery processing (hydrogenation refinery operation 2) that with the heavy feed stock is object, therefore omits explanation.
The condition that hydrogenation demetalization-desulfurization is handled, wish to select, vanadium (V) concentration that makes the HDMS refining oil M6A that obtains below the 2wtppm, be preferably in below the 1wtppm and the sulphur concentration of HDMS refining oil M6A below the 0.5wt%, be preferably in below the 0.3wt%.
The part of the HDMS refining oil M6A that will obtain at hydrogenation demetalization-desulfurization process 4A is delivered to the 4th mixed processes 5A with at least a portion of distilled oil 3A and is mixed, and obtains petroleum products.
In the occasion of the petroleum products that obtains with the 4th mixed processes 5A, set ratio of mixture and make vanadium (V) concentration of petroleum products below 0.5wtppm as gas turbine fuel (GTF).For example the V concentration of HDMS refining oil M6A is that the V concentration of 1wtppm, distilled oil 3A is the occasion of 0wtppm, and the volume ratio of HDMS refining oil M6A and distilled oil 3A was set in 1: 1 or following (side who is HDMS refining oil M6A reduces), mixed.
For the nubbin of not supplying with the 4th mixed processes 5A among the HDMS refining oil M6A that obtains at hydrogenation demetalization-desulfurization process 4A, it is decomposed the raw material of using (HCR) with the raw material or the hydrogenation decomposition of (FCC), petroleum products in the middle of making as mobile contact.Again, the nubbin for do not supply with the 1st mixed processes 5A in hydrogenation refinery oil M3A also can be made into petroleum naphtha, gasoline, light coal wet goods petroleum products M3A '.
Method of refining according to such oil, because at least a portion of hydrogenation refinery oil M3A is mixed with the part of HDMS refining oil M6A, so for example can access the enough low petroleum products of vanadium (V) concentration of gas turbine fuel etc. thus, again, by the nubbin of HDMS refining oil M6A can access metal concentration (V+Ni) lower, decompose with (FCC) or hydrogenation as the contact of flowing and to decompose middle petroleum products with the raw material of (HCR), can the high multiple petroleum products of while production value added expeditiously.
Again, for decompose the middle petroleum products that decomposes the raw material of using (HCR) with (FCC) or hydrogenation as mobile contact, compare with gas turbine fuel (GTF) etc., permissible concentration height for metal, therefore do not follow the load of hydrogenation demetalization-desulfurization, just can improve the yield of the deasphalted oil M4A of solvent deasphalting operation 3A, can suppress by-product amount thus from asphaltene (pitch) M5A of irreducible oil M2A.
Again, in treatment scheme shown in Figure 4, metal concentration and the sulphur concentration of the deasphalted oil M4A that obtains at solvent deasphalting operation 3A are lower, mix that satisfying flows and contact with the part of the lower HDMS refining oil of metal concentration and sulphur concentration and decompose the occasion of decomposing the raw material proterties of using (HCR) with (FCC) or hydrogenation, with its part without hydrogenation demetalization-desulfurization process 4A, mix with the part of HDMS refining oil M6A by the by-pass line shown in the symbol 12A among Fig. 4, be made as the contact of flowing and decompose with the raw material or the hydrogenation decomposition of (FCC) also passable with the middle petroleum products of the raw material of (HCR).
[embodiment 5]
Fig. 5 is the schema of method of refining of the oil of explanation the 5th embodiment of the present invention, the same with example shown in Figure 4, be to represent that producing gas turbine fuel (GTF) simultaneously by stock oil contacts the processing flow chart of the occasion of decomposing the raw material of using (HCR) with the raw material or the hydrogenation decomposition of (FCC) with flowing.
This example is with the main difference point of example shown in Figure 4: at the back segment of above-mentioned hydrogenation demetalization-desulfurization process 4A the HDMS refining oil M6A that will obtain is set and carries out underpressure distillation and handle the underpressure distillation separation circuit 6A that is separated into decompression light oil M7A and decompression irreducible oil M8A.
That is, in the method for refining of oil shown in Figure 5, the HDMS refining oil M6A that will obtain equally with example shown in Figure 4 delivers to underpressure distillation separating treatment operation 6A and carries out the underpressure distillation processing.
Handle as this underpressure distillation, HDMS refining oil M6A is imported vacuum still to be distilled, be separated into low boiling point component and high boiling point composition among the HDMS refining oil M6A, obtain lower boiling decompression light oil M7A, obtain high boiling decompression irreducible oil M8A from tower bottom from top of tower.
Handle owing to carry out such underpressure distillation, therefore, can control extraction yield, make its vanadium (V) concentration ideal higher limit for example become 50wtppm in this example for handling the deasphalted oil M4A that obtains by above-mentioned solvent deasphalting.That is, extraction yield can be increased, the rate of recovery of petroleum products can be improved.
Again, for by such deasphalted oil M4A is handled the HDMS refining oil M6A that obtains by carrying out hydrogenation demetalization-desulfurization, select demetalization-desulfurization condition make its vanadium (V) concentration below the 20wtppm, be preferably in below the 10wtppm, wish simultaneously sulphur concentration below the 0.5wt%, be preferably in below the 0.3wt%.
Again, for such HDMS refining oil M6A is handled the decompression light oil obtain by underpressure distillation, make its vanadium (V) concentration below 1wtppm for well.
After such operation, at least a portion of the decompression light oil M7A that will obtain at underpressure distillation separation circuit 6A is delivered to the 5th mixed processes 7A with distilled oil M3A and is mixed, and obtains one of petroleum products.
In the occasion of the petroleum products that the 5th mixed processes 7A is obtained as gas turbine fuel (GTF), the same with example shown in Figure 4, make its vanadium (V) concentration below 0.5wtppm.At this moment, the same with previous example, adjust ratio of mixture aptly according to vanadium (V) concentration of decompression light oil M7A.Again, when the occasion of vanadium (V) concentration below 0.5wtppm of decompression light oil M7A, also impassable with regard to direct former state ground under the situation that wherein adds distilled oil 3A as gas turbine fuel (GTF).
Again, handle the nubbin of not supplying with underpressure distillation separation circuit 6A among the decompression irreducible oil M8A that obtains and the HDMS refining oil M6A for the nubbin of decompression light oil M7A and underpressure distillation, make them decompose the raw material of using (HCR) with the raw material or the hydrogenation decomposition of (FCC), petroleum products in the middle of making individually or by mixing the mobile contact of conduct aptly.
Method of refining according to such oil, by underpressure distillation operation 6A HDMS refining oil M6A being carried out underpressure distillation handles, boiling spread by the distillation proterties is separated into containing metal and the decompression light oil M7A of residual carbon and the irreducible oil M8A that reduces pressure hardly, therefore can allow that vanadium concentration, metal concentration, the residual carbon of HDMS refining oil M6A itself reach higher concentration, can improve the yield of the deasphalted oil M4A of solvent deasphalting operation 3A thus, therefore can suppress by-product amount from asphaltene (pitch) M5A of irreducible oil M2A generation.
Again, to the deasphalted oil M4A that obtains at solvent deasphalting operation 3A, in its enough low occasion of vanadium (V) concentration, its part imports by-pass line 12A without hydrogenation demetalization-desulfurization process 4A, mix with decompression irreducible oil M8A from underpressure distillation separation circuit 6A, being made as the contact of flowing decomposes with (FCC), the hydrogenation decomposition also can with the intermediates of the raw material of (HCR), also import by-pass line 12A for the HDMS refining oil M6A that obtains at hydrogenation demetalization-desulfurization process 4A again, mix with decompression irreducible oil M8A, be made as the contact of flowing and decompose with (FCC) from underpressure distillation separation circuit 6A, hydrogenation is decomposed with the middle petroleum products of the raw material of (HCR) also passable.
[the 6th embodiment]
Fig. 6 is the schema for the 6th embodiment of the method for refining that oil of the present invention is described, the same with example shown in Figure 4, be to represent that producing gas turbine fuel (GTF) simultaneously by stock oil decomposes the processing flow chart of the occasion of the raw material of using (HCR) with flowing to contact to decompose with (FCC) or hydrogenation.
This example is with the main difference point of example shown in Figure 4: arrange at the back segment of above-mentioned separated operation 1A that the residual oil M2A that will obtain carries out that the decompression distillation separation circuit 20A that is separated into decompression light oil M11 and decompression residual oil M12 is processed in decompression distillation, the decompression residual oil M12A that will obtain carries out solvent deasphalting and process the solvent deasphalting operation 21A that is separated into deasphalted oil M13A and asphaltene (pitch) M14A and the miscella of the deasphalted oil M13A that obtains and decompression light oil M11A is carried out hydrogenation demetalization-desulfurization process and obtain the hydrogenation demetalization of HDMS refined oil M15A-desulfurization process 22A.
That is, in the method for refining of oil shown in Figure 6, the irreducible oil M2A that will obtain equally with example shown in Figure 4 delivers to underpressure distillation separating treatment operation 20A and carries out the underpressure distillation processing.
As this underpressure distillation separating treatment, irreducible oil M2A is imported vacuum still to be distilled, be separated into low boiler cut and high boiling fraction among the irreducible oil M2A, from cat head obtain low boiling point component decompression light oil M11A, at the bottom of tower, obtain high boiling decompression irreducible oil M12A.

Secondly, the deasphalted oil M13A that obtains is like this mixed with above-mentioned decompression light oil M11A, obtain HDMS refining oil M15A by this mixing oil being carried out hydrogenation demetalization-desulfurization processing.For the HDMS refining oil M15A that obtains, wish to select demetalization-desulfurization condition, make its vanadium (V) concentration below the 2wtppm, be preferably in below the 1wtppm, make simultaneously its sulphur concentration below the 0.5wtppm, be preferably in below the 0.3wtppm.
Then, the part of the HDMS refining oil M15A that will obtain at hydrogenation demetalization-desulfurization process 22A is delivered to the 6th mixed processes 23A with distilled oil M3A and is mixed, and obtains the gas turbine fuel as petroleum products one of (GTF) of vanadium (V) concentration below 0.5wtppm.
Again, for the nubbin of not supplying with the 6th mixed processes 23A among the HDMS refining oil M15A that obtains at hydrogenation demetalization-desulfurization process 22A, it can be decomposed with the raw material or the hydrogenation of (FCC) as mobile contact and decompose the raw material of using (HCR), petroleum products in the middle of making.
Metal ingredient and the residual carbon that diasphaltene alkene M13A and decompression light oil M11A contain separately and the sulphur composition is made a world of difference, be pressed with the very occasion of big-difference at reaction conditions especially hydrogen branch, they are not mixed, handle but in reactor separately, carry out hydrogenation demetalization-desulfurization with top condition, mix then, at least a portion of the decompression light oil M11A that perhaps hydrogenation demetalization-desulfurization has been handled is mixed with at least a portion of distilled oil M3A, also can access the gas turbine fuel (GTF) of its vanadium (V) concentration below 0.5wtppm.
