Technical field the Invention relates to oil fuel for gas turbines and more specifically to a method of obtaining fuel oil for gas turbines used for power generation gas turbine, sposobstvo turbine.

Background of the invention In General, thermal generation of electricity using fuel oil provides for the generation of high pressure steam in the boiler with the use of crude oil and/or heavy oil as fuel for the boiler to rotate a steam turbine using the generated steam and generate electricity. However, this system has a low efficiency of electricity generation. Currently developed high-performance large-sized boiler, oil fuel, however, the efficiency of power generation such boiler is only 40%. Thus, this leads to the release of large amounts of energy in the form of greenhouse gas without release. In addition, this leads to the fact that some so x in the gaseous products of combustion or flue gas produced from the system. Although gaseous products of combustion are subjected to desulfurization of flue gas, so x is partly emitted into the atmosphere, causing environmental pollution.

In addition, was established gas turbine power generation system combined cycle, which is adapted to actuate a gas turbine for genericbase heat from the high temperature flue gas. or gaseous products of combustion emerging from the gas turbine to produce steam to drive a steam turbine, generating electricity. The system has been known in the art, since it has a high generation efficiency, a reduced amount of CO2generated per unit of generated energy, and significantly reduced so x and NOx in the flue gas. When the system is used as fuel gas natural gas required to transport it from the gas field to the plant by pipeline or to store liquefied natural gas and turn it into a gaseous state and then burn it in a gas turbine. Unfortunately this increases the cost of the equipment.

Also developed a method of obtaining oil fuel for the gas turbine described in the publications of patent applications in Japan 207170/1994 and 209600/1994. The method described in the first Japanese publication, provides for the processing of low-sulfur crude oil, with salt content, increased to 0.5 ppm or less, atmospheric distillation or vacuum distillation to obtain oil toplevelmenu Japanese publication, provides for the heating of low-sulphur crude oil waste heat obtained from the gas turbine, and the subsequent influence of hydrogen on low-sulfur crude oil to reduce, thus, sulfur and heavy metals in crude oil, then removing the thus treated crude oil, which is then used as fuel oil for gas turbines.

Currently, the problem of environmental pollution has become vital in this industry. So, you want to minimize the content of sulfur compounds in the flue gas. This problem could have been solved by the use of plants for flue gas desulfurization. However, during the production of electricity using fuel oil for gas turbine application installation for desulfurization of flue gas causes loss of efficiency of electricity generation due to loss of pressure, so you want to minimize the sulfur content in fuel for gas turbines. Thus, the method described in the first Japanese publication, leads to a significant limitation of heating oil at atmospheric distillation or vacuum distillation in order, therefore, not to increase kolichestvo for gas turbines. This leads to the fact that the degree of extraction of oil fuel for gas turbines from crude oil are at the level of only 40%, even when using middle Eastern crude oil, which has a low sulfur content. The increase in heating oil to increase the degree of extraction of fuels leads to increased production of sulfur.

In addition, when the method is used for crude oil, which is more accessible and has an increased content of sulfur, removing the light fractions of oil or light residue from the distillation in the same amount leads to the fact that the sulfur content in the light oil fractions exceeds the set level, and they are unsuitable for use as a fuel oil for gas turbines. Thus, this leads to reduce the extraction of light fractions of oil, which leads to the fact that the application of the method for crude oil is technically and economically disadvantageous.

The last Japanese publication describes a method of producing hydrogen using methanol as a starting material and implementation Hydrotreating of crude oil received by hydrogen. However, the method involves the refining of crude oil with low sulfur content, and the application of the method with crude oil, crude oil, not with the light fractions of oil or light distillate obtained by the distillation of crude oil, and thus, it must be adapted to the conditions of processing heavy oil or residue contained in crude oil. This requires an increase in the reaction temperature, pressure, reaction time and reaction time or period of time during which the heavy oil is in contact with the catalyst in the reaction. However, this causes excessive cracking of light fractions in the crude oil, resulting in liquefied petroleum gas or similar contained in large quantities in the oil fuel for gas turbines, and storage of oil fuel part of it passes into the gaseous state. This requires increasing the resistance of the reservoir pressure to a considerably high level. In addition, the reaction temperature and pressure of the reaction should be increased and, thus, the reactor for Hydrotreating has a complex structure and high production cost. In addition, the increase in reaction time requires large size catalyst carrier, which leads to an increase in the size of the reactor and increases the consumption of the catalyst.

The best variant implementation of the invention In Fig. 1 shows an example system for implementing the method of obtaining oil plants of the invention perform the Hydrotreating. In the following description, from the first to the fifth of the Hydrotreating operation will be performed according to the stages of Hydrotreating. Oil fuel for gas turbines, obtained in the process of Hydrotreating operations, in General, are mixed with each other. Thus, the following embodiments of the invention will be described with mixed oil fuel for gas turbines. However, the present invention can be carried out without mixing oil fuel oil fuel used separately from each other.

Original oil 1 can be a crude oil. Original oil 1 first of all, is subjected to a desalting operation section 11 demineralization in such conditions, which is usually used in petroleum refining. The treatment is carried out so that the original oil and water were mixed with each other for translation, thus, salt and mud in the water phase, resulting alkali metal, which adversely affects the gas turbine, is removed. Then desalted original oil served in the atmospheric distillation column 2, where it is divided, for example, on the light fractions of oil or light distillate 21, having a boiling point below 340- C. Learned so light fractions 21 oil then served in the first installation 3 Hydrotreating.

Known atmospheric distillation column 2 for oil treatment is usually performed in such a way that a lot of Windows for removal fractions are located so that they are allocated sequentially from the upper part of the atmospheric distillation column to the bottom, in accordance with the boiling points of the fractions, such as kerosene, gasoline, etc., because the light fractions of oil or light distillate containing fraction with a high boiling point to a low boiling point. As a result, the light oils are output respectively through the window for removal, if necessary. In contrast, shows a variant embodiment of the invention is made so that it enables the output of the light fractions of oil or light distillate together, for example, from the upper part of the atmospheric distillation column 2, leaving the light oils are mixed with each other, then submit light fractions of oil in a setting of 3 for Hydrotreating. The alternative shown in Fig.2 may be so designed that faction in the areas of the respective boiling points were derived through a lot of the fractions are mixed with each other and then they are served in a setting of 3 for Hydrotreating, which faction simultaneously subjected to Hydrotreating. It is shown in Fig.2 atmospheric distillation column is equipped with four such Windows for output.

More specifically, the production of automotive fuel oil subjected to simultaneous or group desulfurization, usually requires changes in operating conditions such as temperature, pressure, catalyst, etc. as gasoline, kerosene and gas oil are different from each other according to the level of desulfurization. In contrast, upon receipt of oil fuel for the gas turbine, when the light fractions of oil or light distillate having a boiling point of, for example, below 350oWith, subjected to simultaneous desulfurization, you only need to bring working conditions according to the technical requirements of the receipt of fuel oil for gas turbines in General and, thus, the operating conditions differ significantly from those used in the refinery. This allows you to put light fractions of oil or light distillate in the atmospheric distillation column 2 the Hydrotreating in the General setting, as described above.

In the process atmospheric distillation light ends of the oil or light distillate containing moustache to obtain fuel oil to gas turbines and, thus, the fraction of light oil can be processed in the plant for Hydrotreating together or in combination. Such joint processing allows to minimize the cost of the equipment. Technique Hydrotreating, which can be used in the shown embodiment, the system allows operation at high temperature, because the shade of oil fuel for the gas turbine does not matter in contrast to the Hydrotreating operation performed in the refinery in the production of automotive fuel oil when work is done at low temperature and high pressure in order to avoid staining of motor oil during operation of the Hydrotreating. This reduces the cost of the reactor, because it operates at a low pressure, which provides an additional reduction in the cost of the equipment.

Now with reference to Fig.3 will be described installation 3 for Hydrotreating and hydrorefining, ongoing. Light fractions of oil or light distillate 21 is mixed with the compressed gaseous hydrogen and then served in the upper part of the reaction column 31. The reaction column 31 is supplied located it with a layer 32 of a catalyst which includes novtel gazoobraznye hydrogen pass through the layer 32 of the catalyst and fed through the lower part of the reaction column 31 through the inlet pipe 33 into the tank 34 high pressure. A small amount of heavy metals such as vanadium, Nickel, lead, etc. that are included in the light oils are 21 or deducted in hydrocarbon molecules, as well as sulfur and nitrogen react with hydrogen over a period of time passing through the layer 32 of a catalyst and, thus, be separated or extracted from the hydrocarbon molecules. The result is that heavy metals are absorbed by the surface of the catalyst, and sulfur and nitrogen react with hydrogen to form hydrogen sulfide and ammonia, respectively. Alkali metals that are dissolved in water, in small quantities contained in the oil substance, or are present in the form of salts, absorbed by the surface of the catalyst. Metals typically contain heavy oil or oil residue, so they are present in small quantities in light petroleum fractions 21.

From the bottom of the reaction column 31 enters a mixed fluid of gas and oil under high pressure of from 30 to 80 kg/cm2which then served in the reservoir 34 high pressure, where hydrogen gas is separated from the mixture. The pressure of the hydrogen gas increases through compressor WED, and then it is served in the mode of circulation in the area is via the regulator PV pressure in the tank 35 low pressure, causing its pressure is reduced, for example, 10-30%. This leads to the fact that liquefied gas, such as hydrogen sulfide, ammonia, etc., dissolved in a liquid substance or oil evaporates. Thus separated purified distillate is a fuel for gas turbines. Reference number 35A marked pump. The gas separated in the tank 35 low pressure, contains unreacted hydrogen and hydrogenated compounds such as hydrogen sulfide, ammonia, etc. and methane obtained by the selection of part of the hydrocarbon molecules, and light oil substance in the range from fractions of liquefied petroleum gas, light oil. Used herein, the term "light oil ingredient" means an ingredient which is easier to light fractions of oil or light distillate 21. The gas separated in the tank 35, is fed into the section 36 remove impurities, where deleted in the gas hydrogen sulphide and ammonia.

Section 36 remove impurities may be provided located in her absorption liquid layer for absorption of impurities, such as, for example, hydrogen sulfide and ammonia, and thus, the passage of gas through the absorption liquid layer provides the removal of haslego in the reaction of hydrogen gas and light oil substance with a reduced number of carbon atoms, such as methane or the like. The mixed gas 42 serves in hydrogen installation 4, in which a light oil matter contained in the mixed gas 42, is used as material for the production of gaseous hydrogen. Part of the light oil fractions 21 allocated in the atmospheric distillation column 2, also served in the hydrogen installation 4 for use as a material for the production of gaseous hydrogen. When applying a source of oil for obtaining hydrogen gas limited heavy oil, oil may be supplied from outside to the hydrogen installation 4 only at the beginning of installation 4.

Hydrogen gas is supplied into the reaction column 31 as described above, is used in circulation, the amount of hydrogen gas contained in the gas in the circulation channel 37, gradually decreases, while the number of light petroleum substances, such as methane and the like, increases. This leads to a relative decrease in the number of gaseous hydrogen. To avoid this situation and, thus, ensure Hydrotreating, hydrogen unit 4 in the circulation channel 37 is fed hydrogen gas 41.

, the which burns fuel gas, and the reaction tube 44 located in the furnace 44. Light oil substance, such as methane, and steam is introduced into the reaction tube 44 so that the light oil substance is subjected to steam reforming to produce hydrogen and by carbon monoxide. Then, carbon monoxide and unreacted light oil substance modify, or delete from gas to produce gaseous hydrogen. Processing of removing or cleaning can be carried out, for example, by adsorption deviation of pressure (PSA), adsorption temperature deviation (TSA), low-temperature separation, membrane separation, or similar methods.

According to the present invention, during 1-5 operations hydrogenation light oil fraction or light oil substance may be introduced into contact with the compressed hydrogen in the presence of a catalyst to perform any of the operations such as (1) hydrodesulfurized or for Hydrotreating desulfurization or the removal of such impurities as sulfur compounds and the like, (2) Hydrotreating to improve the qualities of light fractions of oil or light oil matter due to the saturation of unsaturated hydrocarbons or similar substances, and (3) GI is the first operation of the Hydrotreating is to achieve the above desulfurization (1), the purpose of each of the second and third operations Hydrotreating is the implementation of the above desulfurization (1) t (2), and the purpose of each of the fourth and fifth operations is performed as described above desulfurization (1), Hydrotreating (2) and hydrocracking (3).

Next will be described the process performed in the first installation 3 Hydrotreating. During normal distillation of petroleum separate treatment machine naphtha, kerosene, gas oil, etc. contained in the light fractions of oil or light distillate, and each fraction corresponding to the narrow range of boiling points, is subjected to Hydrotreating. In contrast, according to the present invention, all of the fractions obtained by atmospheric distillation, is subjected to Hydrotreating together or in combination. Thus, the present invention allows a significant increase compared with the prior art, the amount of material subjected to Hydrotreating. The Hydrotreating conditions, such as pressure compressed gaseous hydrogen, the reaction temperature, etc. can vary depending on the type of oil subjected to Hydrotreating, goals, Hydrotreating, etc., More specifically, the temperature and pressure of the hydrogen gas can be selected in dagnogo hydrogen, preferably set in the range from 30 to 70 kg/cm2. In addition, the catalyst may be selected from those catalysts which are usually used according to the prior art. Preferably, the catalyst was prepared by deposition of sulphide Ni, Mo, or on alumina as the carrier. When you need to process Arabian light oil, the pressure of the hydrogen gas can be set in the range of 30 kg/cm2up to 50 kg/cm2that leads to the production of oil fuel for the gas turbine, which has a sulfur concentration, component 450 parts per million or less and the concentration of nitrogen, comprising 30 parts per million or less. In this case, increasing the pressure of gaseous hydrogen up to 40-70 kg/cm2provides increased energy collisions with hydrogen molecules of the oil ingredient so that the sulfur concentration and the nitrogen concentration can be reduced to 200 ppm or less and 20 ppm or less, respectively.

Residual oil (residual oil atmospheric distillation) 22 allocated in the atmospheric distillation column 2, served in a vacuum distillation column 5, in which the oil Oia at atmospheric pressure, equal 565oSince that is the easiest faction in the oil residues 22, and a heavy oil matter or residue (oil residues from the vacuum distillation) 52 with a boiling point at atmospheric pressure above 565oC. Light oil substance 51 serves the second installation 6 Hydrotreating to perform his Hydrotreating.

Hydrogen gas used in the second Hydrotreating, is supplied from the above-described hydrogen unit 4. Gas with a reduced number of carbon atoms, such as methane or the like, obtained in the second installation 6 Hydrotreating, serves as raw material in the hydrogen installation 4. When as a source of oil using Arab light crude, setting the pressure of the hydrogen gas level from 30 to 60 kg/cm2in the second installation 6 Hydrotreating provides reception of low concentrations of sulphur and nitrogen concentration, comprising 2000 ppm or less and 200 ppm or less, respectively. In addition, the pressure of hydrogen gas, comprising from 50 to 100 kg/cm2reduces the sulfur concentration and the nitrogen concentration up to a level of 1000 ppm or less, and 100 ppm or less, respectively.

That is the first substance (oil fuel for gas turbines), from the first installation 3 Hydrotreating (mixing), for use as fuel oil for gas turbines.

Heavy oil substance (oil residues from the vacuum distillation) 52 allocated in a vacuum distillation column 5, is separated into a light oil matter or zaasfaltirovan oil substance 72 and a heavy oil matter or neasfaltirovanyj oil residues 73 to install the deasphalting solvent or installing 71 extraction solvent. The separation is realized by means of the feed oil residue 52 of vacuum distillation and solvent in the installation 71 in the upper part of the column and, in its lower part for introducing them to the countercurrent contact, respectively, resulting in separation from each other of light and heavy oil contained in the oil residues 52 from the vacuum distillation, due to the difference of solubility of the solvent.

Selected so zaasfaltirovan oil substance 72 is mixed with a light oil matter 51 of the vacuum distillation column 5 and then fed to the second installation 6 Hydrotreating. Neasfaltirovanyj oil residue 73 is subjected to regulate the viscosity, if nbrazil, the Hydrotreating is performed in the first installation 3 Hydrotreating and hydrorefining, performed in the second installation 6 Hydrotreating, correspond to the first Hydrotreating operation and the second operation Hydrotreating, respectively, and vacuum distillation performed in a vacuum distillation column 5, and the processing in the setting 71 of the deasphalting solvent correspond to the first and second operations division, respectively.

Shows a variant embodiment of the invention provides for the receipt of fuel oil for gas turbines, which meets the requirements of the composition defined herein "the description of the invention". In the shown embodiment, in each operation of the atmospheric distillation and vacuum distillation followed by Hydrotreating operation and, thus, each of the operations of distillation can be carried out without taking into account the amount of sulfur and heavy metal, which leads to an increase in the quantity of light oil matter. Thus, when the initial oil use crude oil, fuel oil for gas turbine can be made with such high degrees of extraction, as 65% or more and preferably 70-90% (by weight) of the amount of crude tyano residues from atmospheric distillation, and/or heavy oil, oil fuel for the gas turbine can be made with such high degrees of extraction, as 40% or more and preferably 40-75% (by weight) from the number of original heavy oil.

More specifically, assuming that crude oil is served in the relative quantity of 100 units in the atmospheric distillation column 2, the light oils and oil residues from atmospheric distillation allocate it in the ratio of 60:40. Light oil substance and oil residues from vacuum distillation can be allocated in the ratio 40:20 on the basis of oil residues from atmospheric distillation in the relative amount of 40 units. In addition, oil residues from vacuum distillation in the relative amount of 20 units can be recycled in the plant 71 of the deasphalting solvent, resulting in a gain zaasfaltirovan oil substance and neasfaltirovanyj oil residues in the ratio of 10:10. When as a primary source of oil use crude oil may be oil fuel for gas turbines, which contains a light oil matter, light oil matter from vacuum distillation and zaasfaltirovan oil substance in the ratio of 60:20:ucaut even when asphalt destroying. Thus, when using crude oil as the primary source of oil, the present invention provides for the receipt of fuel oil for gas turbines with degrees of extract 65% or more and preferably 70-90%, depending on the type of the original oil.

In addition, when the primary source of oil use a heavy oil, which represents the oil residues from atmospheric distillation and/or heavy oil in the relative quantity of 100 units, a light oil matter and oil residues from vacuum distillation can be allocated in the ratio of 50: 50 in the vacuum distillation column 5. Oil residue from the vacuum distillation in the relative quantity of 50 units provide zaasfaltirovan oil substances and deasphalting oil residue in the ratio 25:25 installation 71 of the deasphalting solvent. Thus, when as a source of oil used original heavy oil can be obtained from fuel oil to gas turbine, consisting of a light oil matter from vacuum distillation and zaasfaltirovan solvent oil substance in the relative number 50:25, resulting in a degree izlechivalsya. In Fig.1 by broken lines shows that the heavy oil is subjected to desalting and then fed to a vacuum distillation column 5. The present invention, when used as a source of heavy oil original oil due to changes because of the differences in types of source oil provides the fuel oil for gas turbines with degrees of extraction of 40% or more and preferably 40-75%.

The present invention is carried out with the Hydrotreating of light fractions of oil or light distillate after the operation of distillation and not to the direct hydrotreatment of crude oil and, therefore, is only required to determine the reaction conditions, adequate light oil fractions. Thus, the increase in pressure and the reaction temperature can be minimized, and the reaction time can be reduced, which leads to simplification of the system. In addition, the present invention is directed to the obtaining of oil fuel for the gas turbine in such a way that the fractions obtained during the distillation operation, is subjected to Hydrotreating together or in the aggregate, which leads to simplification of the way.

According to the present invention, the heavy oil may be supplied into the vacuum rectification Atisa in the installation 71 of the deasphalting solvent. This option is filing does not affect the series of operations, beginning with the supply of crude oil atmospheric distillation column 2. Thus, it does not affect the degree of extraction of oil fuel for gas turbines, produced from crude oil. The number of oil fuel for gas turbines simply increases with the number of additional source of oil and, therefore, it is included in the scope of the present invention.

In addition, the present invention is not limited to such a design, where light oil substance obtained during the second operation, separation, or zaasfaltirovan oil substance 72 received in the installation 71 of the deasphalting solvent is processed in the second installation 6 Hydrotreating. Thus, it can be processed during the third operation Hydrotreating or third setting 60 Hydrotreating, is located separately from the second installation of 6 Hydrotreating. The overall implementation of the second and third Hydrotreating operations as in the variant shown in Fig.1, requires the determination of reaction conditions, adequate heavy oil matter, resulting in the pressure of the hydrogen gas is at such a high level to the mu, that the pressure of hydrogen gas during the second and third operations is 50-150 kg/cm2and 80-200 kg/cm2respectively. Thus, separate operations provides a significant reduction in the amount of material processed during the third Hydrotreating operation, therefore, the reaction pressure tank can be reduced in size. In any case, the system may have pre-emptive design depending on its scale, as necessary.

According to the present invention, when performing the three operations Hydrotreating the first and third operations can be performed collectively or jointly. Alternatively, the operation of the three can be generalized.

According to the present invention, the first separation operation carried out for the separation of oil residues 22 obtained in the atmospheric distillation column 2, is not limited by vacuum distillation. It can be run by steam distillation, deasphalting solvent, thermal cracking for heating oil residues 22 to a temperature component, for example, 430-490oFor fractionation uglevodoroda or the like. The implementation of the first operation of separation by deasphalting solvent may be carried out in such a manner as shown in Fig.6, which illustrates another variant of implementation of the present invention. Oil residues 22 from atmospheric distillation served in the installation 81 deasphalting solvent, with the result that they are separated into a light oil matter (zaasfaltirovan solvent oil substance) 82 and a heavy oil matter (neasfaltirovanyj solvent oil residues) 83. Light oil substance 82 serves the second installation 6 Hydrotreating.

In the embodiment of the invention shown in Fig.6, the second separation operation is not performed. However neasfaltirovanyj solvent oil residues 83 may be subjected to a second operation of separation, as in the variant shown in Fig.1. The second separation operation can be performed by the above-described thermal cracking.

Heavy oil a substance selected during the first operation of separation, may be subjected to Hydrotreating, as shown in Fig.7, which illustrates another variant of implementation of the present invention. More specifically, the heavy oil matter (on VERTOU installation 91 Hydrotreating to separate light oil substance 92 and heavy oil substance 93. The fourth installation 91 Hydrotreating is located after the installation shown in Fig.3, and includes a distillation unit for the separation of heavy oil substances 83 on light oil substance 92 and heavy oil substance 93, such as, for example, the installation for atmospheric distillation or installation for vacuum distillation.

Each of these constructions of the embodiments of the invention also provides for the receipt of fuel oil for gas turbine heavy oil components isolated during the first operation of separation (for example, the operation of the deasphalting solvent), resulting in significantly increased extraction of oil fuel for gas turbines. Alternatively, the portion of the source oil may be fed into the fourth installation 91 Hydrotreating, which is mixed with heavy oil substance 83 received in the installation 81 deasphalting solvent.

In addition, the present invention can be implemented as shown in Fig.8, which illustrates another another variant implementation of the present invention, in the shown embodiment, oil residues 22 obtained during the operation of the atmospheric distillation, served in the fifth mouth light oil substance 102 and heavy oil substance 103 thus, what light oil substance 102 can be mixed with petroleum fuel for gas turbines, obtained in the first installation 3 Hydrotreating. The fifth installation 101 Hydrotreating includes the same main line installation as the fourth installation 91 Hydrotreating.

Heavy oil substance 103 is served in the installation 111 of the deasphalting solvent for the separation of light oil matter (zaasfaltirovan oil substance) 112 and a heavy oil matter (neasfaltirovanyj oil residues) 113. The selected light oil substance 112 is used as fuel oil for the gas turbine, mixing it, for example, with a light oil substance 102 received in the fifth installation 101 Hydrotreating, and heavy oil substance 113 using, for example, as fuel oil for boiler. The third operation of the separation is not limited to the operation of the deasphalting solvent and may be in the form of operation of thermal cracking process or the operation of the vacuum distillation. Shown also provides for the extraction of oil fuel for gas turbines from the original oil in such a high degree as 65% or more and preferably 70-90%. Light oil substance (gas), such as methane or Eisenach in Fig.7 and 8, served in a hydrogen installation 4 for the production of gaseous hydrogen.

In the above-described variants of the invention, the light fractions of oil or light distillate 21 obtained in the atmospheric distillation column 2, and a light oil matter (light oil substance from the vacuum distillation) 51, obtained in the vacuum distillation column 5, is then recycled to the hydrotreatment units, respectively, different from each other. In an alternative embodiment, the present invention can be implemented as shown in Fig. 9, which illustrates another another variant implementation of the present invention. In the shown embodiment, light fractions 21 oil and light oil substance 51 mixed together and then subjected to Hydrotreating in the installation of 6 Hydrotreating. This design represents the combination of the first installation of 3 units of the second installation 6 Hydrotreating in the variant shown in Fig.1. In General, the reaction conditions for Hydrotreating define adequately the heavy oil matter contained in the original oil. In the shown embodiment, the heavy oil substance corresponds to the light oil matter (light oil matter from vacuum distillation) 51. together, while reducing the weight ratio (volumetric ratio) of light oil substance 21 and a light oil matter 51 from vacuum distillation in the original oil. Such processing avoids the use of plants for Hydrotreating of light oil substances, thereby reducing production costs. The increase in the content of light petroleum substances 21 or reducing the content of light petroleum substances 51 from the vacuum distillation requires reaction conditions were established adequately heavy oil substance in accordance with a light oil matter 51 from vacuum distillation in a small amount. This complicates the design of the reactor or makes it unreliable as a result he will not have a satisfactory economic benefits. In contrast, setting the reaction conditions adequately light the oil substance 51 from the vacuum distillation significantly improves the cleaning light oil matter.

In the embodiment of the invention shown in Fig.9, the first separation is carried out, for example, vacuum distillation. However, the first separation operation may be implemented by any other suitable postanovka 61 Hydrotreating together or in combination.

When the process of installing 61 Hydrotreating is carried out using Arab light oil, install the pressure of the hydrogen gas in the range of 30-60 kg/cm2provides reception of low concentrations of sulfur and nitrogen in petroleum fuel for gas turbines, as 500 parts per million or less, and 50 ppm or less, respectively. Increasing the pressure of the hydrogen gas to the level of 50-100 kg/cm2additionally reduces the concentration of sulfur and nitrogen to such low levels as 300 parts per million or less and 30 ppm or less, respectively.

The purified distillate obtained by simultaneously processing a light oil matter and light fractions 21 oil installation 61 Hydrotreating, quite suitable for use as a fuel oil for gas turbines. Alternatively, the purified distillate, as shown in Fig. 10, is subjected to distillation at a temperature of, for example, 350oIn the atmospheric distillation column 62 so that the received light oil substance can be used as a higher-quality fuel oil for the gas turbine, and the resulting oil residue can be used as oil t sestultima so, that heavy oil substance obtained in the course of the first separation operation, the second operation of the separation and/or third operations of separation, partially oxidized with gaseous oxygen to produce hydrogen, which is then used in the Hydrotreating unit. The Hydrotreating unit can be setup to be used in any of the Hydrotreating operations from the first to the fourth. In Fig.11 shows another variant implementation of the present invention, which provides execution of such Hydrotreating. More specifically, residual oil, supplied from the unit 81 of the deasphalting solvent, is subjected to partial oxidation to produce hydrogen, which is then fed to the first installation 3 Hydrotreating and second installation 6 Hydrotreating. Reference number 63 marked oxygen apparatus for extracting oxygen from air, and the reference number 64 marked the installation of the partial oxidation. Heavy oil substance that is necessary to partially oxidize, is not limited to oil residue obtained in the installation 81 deasphalting solvent, and thus, any oil residues obtained during the first operation of separation in the vacuum distillation column 5 or poenae substance, obtained during the second or third operations of separation.

Setting the partial oxidation may have the construction shown in Fig.12. In setting 4, shown in Fig.12, the heavy oil matter and high-pressure steam is heated and then injected into the reaction furnace 65 together with oxygen and, thus, get gas, mainly consisting of CO and H2in the reaction of partial oxidation conditions comprising a temperature of 1200-1500oC and pressure 2-85 kg/cm2. The gas is then quenched or rapidly cooled to 200-260oWith the help of water in the cooling chamber located below the reaction furnace 65. This allows to extract the major part of the unreacted carbon and enter into gas pairs, necessary for the subsequent conversion process. Then the gas is fed to the washing column 66, in which the entire remaining unreacted carbon can be completely removed from the gas. Then it is served in a CO-Converter 67, which, remaining in the gas is converted to CO2by reaction WITH steam using, for example, cobaltmolybdenum catalyst. Subsequently, an oxidizing gas, such as CO2and like him, absorbed in bash the toty.

Oil fuel for gas turbines, obtained according to the present invention can be used, for example, to generate electricity, as shown in Fig.13. More specifically, fuel for the gas turbine is burned in the burning nozzle, resulting in a gain of gaseous combustion products, which are then used to actuate the gas turbine 201 so that the generator 202 generates electricity. The gas turbine 201 emits a high-temperature exhaust gas, which is fed to the HRSG waste heat 203, which generates steam using the heat of exhaust gas. Steam provides actuation of the steam turbine 204, resulting in the generator 205 generates electricity. This generation provides effective utilization of waste heat fuel oil for the gas turbine, thereby improving the efficiency of electricity generation.

Examples of the application of the invention described below.

Example 1 Arab light crude oil (contents S: 1.77 wt.%), which is the most affordable in the art, was used as a source of oil for the production of fuel oil is the cue fraction of oil or light distillate 21 with a boiling point of 350oC or lower and heavier fractions of crude oil or oil residues 22 with a boiling point above 350oWith the pressure of the hydrogen gas during the first operation of the Hydrotreating was set at 45 kg/cm2in the resulting oil fuel for gas turbines. In addition, during operation of the vacuum distillation through a separation of the received light oil substance 51 with a boiling point of 565oOr lower (boiling point at atmospheric pressure) and heavy oil substance 52 having a boiling point above 565oC. additionally, the pressure of hydrogen gas during the second operation of the Hydrotreating was set at 55 kg/cm2to obtain fuel oil for the gas turbine, which then was mixed with the oil fuel for gas turbines, obtained during the first operation of the Hydrotreating. Any alkali metal, alkaline earth metal, V and Pb was not detected in the mixed fuel to a gas turbine, which has a concentration of sulfur component 430 parts per million, and viscosity, component 1,3 cSt at 100oC. the Degree of extraction of oil fuel for gas turbines amounted to 84% of the original oil. Was obname which is 1300oC.

Simulations were made assuming that all the energy is obtained from crude oil converted to power generation (power generation gas turbine and power generation boiler). Power supply refinery, power generation efficiency of the gas turbine combined cycle and the power generation efficiency of the boiler was set at 4%, 49% and 38%, respectively. Under these conditions, the final extraction capacity was calculated by setting the number of the original crude oil delivered to the refinery, as 100 units in units of calorific value. In the result it was found that can be extracted 45,7 units of capacity in units of calorific value.

Comparative example 1 Oil fuel for gas turbines was obtained according to the method described in published patent application Japan 207179/1994. According to Japanese publication as a source of oil was used low-sulfur crude oil, in which the salt concentration increased to 0.5 ppm or less, for production of oil fuel for a gas turbine having a sulfur concentration of 0.05 wt.% or less. Arabski way the crude oil was processed according to the method described in the Japanese publication, resulting by distillation were selected petroleum fraction having a sulfur concentration of 0.05 wt.% or less. Oil fuel for gas turbines, obtained according to this publication, had only the fraction of light naphtha to kerosene, which have a boiling point up to 245oC. Also, any alkali metal, alkaline earth metal, V, and Pb in the oil fuel for gas turbines have been identified. In addition, it had a sulfur concentration of about 470 ppm and the viscosity of 0.3 cSt at 100oWith, as a result, it had better quality. However, the degree of extraction of oil fuel for the gas turbine from the amount of the original oil was low and amounted to 24%.

Modelling was conducted essentially to the same conditions as described above in example 1, except that the power for the power station was established at the level of 3%. The final extraction capacity was calculated by setting the number of the original crude oil delivered to the refinery, as 100 units in units of calorific value. In the result, it was found that the degree of extraction of power which gave much worse results for the generation of energy in comparison with the present invention.

Example 2 From the number of samples of crude oil in the Middle East Omani crude oil known as having a relatively low sulfur content. This Omani crude oil was used to produce fuel oil for the gas turbine system shown in Fig.1. Omani crude oil has a sulfur concentration, component 0,94 weight. %, and thus it corresponds to a low-sulfur crude oil, are described in published patent application Japan 207179/1994. In example 2, the crude oil was subjected to atmospheric distillation, whereby it was divided into light fractions of oil or light distillate 21 with a boiling point of 350oC or lower and heavier fractions of crude oil or residual oil having a boiling point above 350oC. Also, the pressure of hydrogen gas during the first operation of the Hydrotreating was set at 40 kg/cm2in the resulting oil fuel for gas turbines. Also, during operation of the vacuum distillation through a separation of the received light oil substance 51 with a boiling point of 565oOr lower (boiling point at atmospheric pressure) and heavy oil substance 52 having a boiling point above 565oC. in Addition, the Yes is to get the oil fuel for the gas turbine, that was then mixed with the oil fuel for gas turbines, obtained during the first operation of the Hydrotreating. Any alkali metal, alkaline earth metal, V and Pb was not detected in the mixed fuel to a gas turbine, which has a concentration of sulfur component 410 parts per million, and viscosity, component 1,1 cSt at 100oC. the Degree of extraction of oil fuel for gas turbines amounted to 85% of the original oil. It was found that fuel oil for gas turbines can be used for gas turbine inlet temperature which is 1300oC.

Simulations were made assuming that all the energy is obtained from crude oil converted to power generation (power generation gas turbine and power generation boiler). Power supply refinery, power generation efficiency of the gas turbine combined cycle and the power generation efficiency of the boiler was set at 4%, 49% and 38%, respectively. Under these conditions, the final extraction capacity was calculated by setting the number of the original crude oil supplied to an oil head is 5.8 units of capacity in units of calorific value.

Comparative example 2 fuel Oil for gas turbines was obtained from the same Omani crude oil, as described above in example 2 according to the method described in published patent application Japan 207179/1994. The production was carried out as described above in comparative example 1. The crude oil was processed according to the method described in the Japanese publication, resulting by distillation were selected petroleum fraction having a sulfur concentration of 0.05 wt.% or less. Oil fuel for gas turbines, obtained according to this publication, had only the fraction of light naphtha to kerosene, which have a boiling point up to 250oC. Also, any alkali metal, alkaline earth metal, V and R in the oil fuel for gas turbines have been identified. In addition, it had a sulfur concentration of about 490 ppm and the viscosity of 0.45 cSt at 100oC. However, the degree of extraction of oil fuel for the gas turbine on the number of initial oil significantly decreased to as low as 35%, regardless of the fact that the original oil is a low-sulfur crude oil.

Modelling was conducted essentially to the same conditions as in the Rovno 3%. The final extraction capacity was calculated by setting the number of the original crude oil delivered to the refinery, as 100 units in units of calorific value. In the result, it was found that the degree of extraction capacity in units of calorific value was low and constituted 40.7 units. Thus, comparative example gave significantly worse results for the generation of energy in comparison with the present invention, regardless of the fact that used the original oil had reduced sulfur content.

Thus, according to the present invention, crude oil is subjected to atmospheric distillation to separate light fractions of oil or light distillate and oil residues from atmospheric distillation. The light oils are then subjected to Hydrotreating, and oil residues from atmospheric distillation is subjected to a separation or Hydrotreating, resulting in an easy oil substance. The thus obtained light oil substance is then subjected to Hydrotreating to obtain a purified distillate, which is used as fuel oil for gas turbines. Thus, the present invention provides for obtaining the oil is STV fuel oil.
