Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for producing gas turbine fuel oil used as fuel for gas turbine power generation and to a gas turbine fuel oil.

[0002]

2. Description of the Related Art In conventional oil-fired power generation, high-pressure steam is generated using crude oil and / or heavy oil as fuel for a boiler, and the steam turbine is turned to generate power. However, this system has low power generation efficiency,
At present, high-efficiency large oil-fired boilers are also being developed, but their power generation efficiency remains at around 40%.

On the other hand, power is generated by turning a gas turbine using natural gas as a heat source, exhaust heat is recovered from high-temperature exhaust gas from the gas turbine, steam is generated, and power is generated by turning the steam turbine. There is a gas turbine combined cycle power generation (hereinafter abbreviated as gas turbine power generation) system. This system is attracting attention because of its high power generation efficiency, low CO2 emission per power generation unit, and extremely low SOx and NOx emissions during flue gas.

By the way, when natural gas is used as a raw material, it is transported from a gas field to a power generation facility by pipeline, or
After storing and vaporizing NG, it has to be burned in a gas turbine, which causes a problem of high equipment cost. For this reason, a method of using light oil as gas turbine fuel has been proposed.

[0005]

Generally, light oil generates smoke due to incomplete combustion depending on the hydrocarbon composition, and depending on the amount of the light oil, it is expected that soot generated as an unburned substance will adversely affect the environment.

[0006] It is known that this smoke-generating property deteriorates as the amount of unsaturated hydrocarbons and aromatic hydrocarbons increases, and that the smoke-generating properties increase particularly when aromatic hydrocarbons are contained. The present inventor is also studying that crude oil is subjected to atmospheric distillation, the atmospheric residue is further subjected to a separation treatment by vacuum distillation or the like, and light oil is taken out from the atmospheric residue and used as a gas turbine fuel oil. However, aromatic hydrocarbons increase with an increase in the distillation temperature at normal pressure, and therefore, it is not uncommon for gas oil obtained by performing vacuum distillation in the subsequent stage to have a composition exceeding 40% by weight. In the case of catalytic cracking oil in refineries, 60
% May contain aromatics.

The inventor of the present invention has considered using light oil containing aromatic hydrocarbons as gas turbine fuel oil. However, when light oil containing a large amount of aromatic hydrocarbons is used, the exhaust heat recovery boiler is used. It has been found that unburned soot adheres to the heat transfer surface of the heat converter and the heat exchange efficiency is significantly reduced, and furthermore, the problem is that the unburned soot adheres to the surface of the denitration catalyst and deteriorates the catalytic performance.

The above problems are closely related to the aromatic content of the light oil, and it has been found that when the amount is 30% by weight or more, the above problems become remarkable. On the other hand, as a gas turbine fuel oil, it has also been found that when the aromatic content is low, that is, when the amount of the paraffinic saturated hydrocarbon increases, there is a problem that the wax component precipitates and solidifies at a low temperature. Has been found to be optimal as a gas turbine fuel oil.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method for producing a gas turbine fuel oil which does not adversely affect an exhaust heat recovery boiler or a denitration catalyst and has low smoke emission. . Another object of the present invention is to effectively utilize a normal pressure residue obtained by distilling a feed oil at normal pressure as a gas turbine fuel.

[0010]

According to the present invention, a light oil having an aromatic hydrocarbon content of 30% by weight or more is mixed with a light oil having an aromatic hydrocarbon content of less than 30% by weight. And the content of aromatic hydrocarbon is at least 6% by weight and at least 30% by weight.
Less than 10 cSt at 130 ° C, 1 ppm or less alkali metal, 1 ppm or less lead, 0.5 ppm or less V, 2 ppm or less Ca, and 500 ppm or less sulfur at 130 ° C. As the light oil having an aromatic hydrocarbon content of 30% by weight or more, a light oil is taken out from a crude oil and / or an atmospheric residue obtained by atmospheric distillation of heavy oil, and the light oil is hydrogenated. The processed one can be mentioned.

An aromatic hydrocarbon content of 30% by weight
Examples of the light oil having a value of less than 1 include a light oil obtained by distilling crude oil at normal pressure. In this case, the light oil may be further hydrotreated. The present invention also covers the gas turbine fuel oil produced in this manner.

[0012]

FIG. 1 is an explanatory view showing an example of a system for carrying out a method for producing gas turbine fuel oil according to the present invention, which will be described as a first embodiment.
The feedstock oil 1 may be either crude oil or heavy oil, or a mixture of crude oil and heavy oil. The feedstock is first desalted in the desalination section 11. This treatment mixes the feedstock oil with water and transfers the salt and mud to the aqueous phase, thereby removing alkali metals that adversely affect the gas turbine. The desalted raw material oil 1 is sent to the atmospheric distillation column 2, for example, a first light oil 21 having a boiling point lower than 340 ° C. to 370 ° C. and a residual oil having a boiling point higher than that (an atmospheric residual oil).
22.

The first light oil 21 can be further separated and used depending on the level of the boiling point.
An outlet for the fraction is provided in order from the top to the bottom of the
Separation is performed such that the target light oil is taken out from the outlet corresponding to each boiling point. Then, the separated first light oil 21 is subjected to, for example, a hydrotreating process or a gasoline production process in a not-shown treatment process, and is used as LPG, gasoline, kerosene, light oil, or the like.

On the other hand, the residual oil (normal pressure residual oil) 22 separated in the atmospheric distillation column 2 is heated to a predetermined temperature in a heating furnace 30 and then sent to the vacuum distillation column 3 where it is subjected to atmospheric pressure. Light components among the residual oils, for example, a light oil (pressure-reduced light oil) 31 having a boiling point lower than 565 ° C. at normal pressure and a heavy component,
It is separated into heavy oil (vacuum residual oil) 32 whose normal pressure boiling point exceeds it. In this example, the feedstock oil 1 composed of crude oil and heavy oil is added to the atmospheric residue and supplied to the vacuum distillation column 3. The separated light oil 31 is sent to the hydrotreating unit 4.

In the hydrotreating unit 4, the hydrogen gas 51 pressurized from the hydrogen plant 5 and the light oil 31 are passed through the catalyst layer, so that a very small amount of hydrocarbons contained in the hydrocarbon molecules in the light oil 31 are introduced. Of impurities such as vanadium, nickel, and lead (the metal content is very small because it is mainly contained in heavy oil), sulfur, and nitrogen. For example, sulfur and nitrogen react with hydrogen to form hydrogen sulfide and ammonia, respectively. The alkali metal is dissolved in some water contained in the oil or exists in the form of a salt, but is adsorbed and removed on the catalyst surface. Further, the unsaturated hydrocarbons in the light oil 31 react with hydrogen to be converted into saturated hydrocarbons, but the conversion of aromatic hydrocarbons into saturated hydrocarbons does not proceed very much. After passing through the catalyst layer, the gas separated from the liquid (oil) by decreasing the pressure is sent to a hydrogen plant 5 after removing impurities such as hydrogen sulfide and ammonia, and is used as a raw material for producing hydrogen gas. Can be

The hydrogen gas 5 in the hydrotreating unit 4
1 is, for example, 50 to 70 kg / cm 2, the reaction temperature is, for example, 340 ° C. to 380 ° C., and LHSV (Liquid Hourly) is used.
Space Velocity) is set to 0.5 hr -1 to 3 hr -1, respectively, and by performing the hydrogenation treatment under such process conditions, the viscosity at 100 ° C. is 4 cSt or less, the alkali metal is 1 ppm or less, and the lead is 1 ppm or less. , V (vanadium) is 0.5 ppm or less and sulfur is 500 ppm or less (a second light oil 53). Thus, almost all of the unsaturated hydrocarbons contained in the second light oil 53 become saturated hydrocarbons, but the aromatic hydrocarbons are hydrocracked into three rings and two benzene rings to form a single ring. However, a monocyclic benzene ring has a strong bonding force, so that further decomposition is rarely performed. For this reason the second
The content of aromatic hydrocarbons in the light oil 53 may be considerably large, for example, 40% by weight.

A gas turbine fuel oil is manufactured by mixing the second light oil 53, which is the fuel oil thus taken out, with another third light oil. As the third light oil, for example, a part of the light oil 21 separated in the atmospheric distillation column 2 can be used. As the third light oil, a light oil having a low content of aromatic hydrocarbons, for example, a light oil of Daqing oil which is one of high quality oils (eg, light gas oil, kerosene, heavy naphtha, etc.)
54 may be brought from another refinery and used. The component of the third light oil 54 does not contain a metal component and has a viscosity of 10%.
It is preferable that the temperature is 2 cSt or less at 0 ° C., the nitrogen concentration is 100 ppm or less, and the sulfur concentration is 500 ppm or less.

Here, the content of each aromatic hydrocarbon in the second light oil 53 and the third light oil 54 and the mixing ratio thereof need to satisfy the following conditions. That is, the aromatic hydrocarbon content of the second light oil 53 is n (n
Is 30% or more) by weight, the content of the third light oil 54 is m weight%, and the amount of the third light oil 54 is “a” with respect to the amount “1” of the second light oil 53. In the case of mixing only, it is necessary to satisfy the following expression (1). According to the formula (1), the content of the aromatic hydrocarbon contained in the mixed oil (gas turbine fuel oil) becomes smaller than 30% by weight. (N + am) / (1 + a) <30 (1) For example, when the aromatic hydrocarbon content of the second light oil 53 is 4
Assuming that the content of the aromatic hydrocarbon in the third light oil 54 is 0% by weight and the content of the aromatic hydrocarbon in the third light oil 54 is 5% by weight, 0.4 <a must be satisfied from the equation (1). Light oil 53 and 3rd
When the light oil 54 is mixed at a ratio of 1: 1, the aromatic hydrocarbon content of the mixed oil becomes 22.5% by weight.

Further, the gas turbine fuel oil obtained by this mixing has, for example, a viscosity of 4 cSt or less at 100 ° C., an alkali metal of 1 ppm or less, a lead of 1 ppm or less, a V (vanadium) of 0.5 ppm or less, and a sulfur of 500 ppm or less. And nitrogen is preferably 100 ppm or less. With such a quality, the combustion temperature is high, the adverse effect on the blades of the turbine is small, and it can be used sufficiently, and the adverse effect on the environment is also suppressed. The mixing ratio of the second light oil 53 and the third light oil 54 generally satisfies the gas turbine fuel oil requirements in terms of viscosity, metal content, and the like of the second light oil 53. Actually, it is determined in terms of the content of the aromatic hydrocarbon.

A second light oil 53 and a third light oil 54
The mixed oil (gas turbine fuel oil) obtained by mixing
When the content of the aromatic hydrocarbon is too low, the low-temperature fluidity is reduced and the handling property is affected, and the content of the aromatic hydrocarbon is 6% by weight or more, generally 10 to 30% by weight, more generally Is preferably 15 to 30% by weight.

The other heavy oil 32 (vacuum residual oil) separated in the vacuum distillation column 3 is used as a raw material oil 1 if necessary.
(Crude oil or heavy oil) and can be used as boiler fuel oil.

According to the above-described embodiment, the light oil (fuel oil) obtained by subjecting the atmospheric residual oil to vacuum distillation and hydrotreating can be used as a gas turbine fuel oil containing less aromatic hydrocarbons. In generating power, it is possible to suppress the generation of smoke without providing an electric precipitator for treating a smoke-generating substance generated when an aromatic hydrocarbon is burned. Therefore, a decrease in pressure loss can be avoided, high power generation efficiency can be obtained, and environmental pollution is small. As a result, the atmospheric residual oil can be effectively used as the gas turbine fuel oil.

In the above-described embodiment, the method of producing gas turbine fuel oil using the light oil 31 obtained by separating the atmospheric residual oil 22 in the vacuum distillation tower 3 has been described, but the separation step is limited to vacuum distillation. Instead, a catalytic cracking method, a steam distillation method, a solvent stripping method, or the like may be used.

Next, a second embodiment will be described with reference to FIG. The treatment process of the atmospheric residual oil in the second embodiment is to catalytically crack the second light oil 53 in the first embodiment by the catalytic cracking device 6. The catalytic cracking device 6 includes a riser 6 having a small pipe diameter.
1, the light oil (second light oil 53) supplied from the lower side and the catalyst supplied from the catalyst supply part 62 are passed upward at a high speed together with a carrier fluid, for example, oil vapor and steam, to form a riser-61. Is separated into a catalyst and a vapor by a sudden increase in the cross-sectional area in a disengager 63 having a large pipe diameter which is connected to the upper end of the column, and the cracked oil component as the vapor is rectified (atmospheric distillation column) 64 Distill at.

Then, gasoline is obtained from the upper stage of the rectification column 64, and fourth light oil (light oil or kerosene) 65 is obtained from the middle stage. Assuming that the second light oil 53 contains, for example, about 40% by weight of aromatic hydrocarbons, this is catalytically cracked to produce gasoline, which is included in the fourth light oil 65 as cracked oil. The amount of the aromatic hydrocarbon to be obtained is, for example, about 55% by weight. Therefore, it is used as a gas turbine fuel oil after being mixed with the third light oil 54 to reduce the content of aromatic hydrocarbons to 6% by weight or more and less than 30% by weight. The heavy oil obtained from the bottom of the rectification column 64 is used as boiler fuel oil together with the heavy oil 32 that is the vacuum residue obtained from the bottom of the vacuum distillation column 3.

The fourth light oil 65 in the present embodiment has a viscosity of 4 cSt or less at 100 ° C., an alkali metal of 1 ppm or less, a lead of 1 ppm or less, a V (vanadium) of 0.5 ppm or less, and a sulfur of 500 ppm or less. Yes, the gas turbine fuel oil is substantially satisfied even as it is, so that the fourth light oil 65 and the third light oil 54 are mixed by considering only the aromatic hydrocarbon content, A gas turbine fuel oil satisfying the rules described in the first embodiment can be obtained.

The above-mentioned process of decomposing atmospheric residue by combining vacuum distillation and catalytic cracking is intended mainly to produce gasoline from vacuum gas oil (second gas oil 53) desulfurized by hydrotreatment. It is performed as. Therefore, the cracked light oil obtained by the catalytic cracking process (the fourth light oil 6)
In 5), a large amount of aromatic hydrocarbon is generated by each reaction such as cyclization and dehydrogenation generated in the process, and it is difficult to use as a gas turbine fuel oil as it is, but according to the present embodiment, It can be used effectively as gas turbine fuel oil.

Therefore, the production of gasoline and the production of light oil required for the production of gas turbine fuel oil can be performed in combination, and the atmospheric residual oil can be effectively used as an energy source. In the gas turbine combined cycle power generation described below, power generation can be performed using both gasoline and gas turbine fuel oil produced through a post-process. Therefore, by combining this embodiment with the gas turbine combined cycle power generation system. The construction of a system with high energy efficiency becomes possible.

FIG. 3 shows a third embodiment of the present invention, in which the light oil 21 obtained in the atmospheric distillation column 2 is hydrotreated in the hydrotreating apparatus 7, and the refined oil thus obtained is obtained. A part of 71 may be mixed with the second light oil 53 as a third light oil, that is, a light oil having an aromatic hydrocarbon content of less than 30% by weight according to the present invention. The main purpose of this hydrotreating process is hydrodesulfurization for removing impurities such as sulfur compounds. Since the refined oil 71 is obtained by refining the light oil 21 obtained by atmospheric distillation, the aromatic hydrocarbon content is, for example, 22% by weight, and it can be used alone as a gas turbine fuel. Is mixed with the light oil 53 as a diluent. In this case, as an example of reaction conditions performed in the hydrotreating apparatus 7, the pressure of the hydrogen gas 51 is, for example, 35 to 50 kg / cm 2, the reaction temperature is, for example, 350 to 380 ° C., and the LHSV (Liquid
Hourly Space Velocity) is set to 1 hr -1 to 4 hr -1, respectively, and by performing the hydrogenation treatment under such process conditions, the viscosity is 4 cSt or less at 100 ° C., the alkali metal is 1 ppm or less, and the lead is 1 ppm or less. , V (vanadium) is 0.5 ppm or less and sulfur is 500 ppm or less. The remaining portion of the refined oil 71 that is not mixed with the second refined oil 53 is used as, for example, gas turbine fuel oil.
Therefore, about 80% of the light oil 71 is added to the light oil 53 at the following ratio. Light oil 71: Light oil 53 =
When mixed at a ratio of 6: 5, a gas turbine fuel oil having an aromatic content of 29.5% by weight can be obtained.

In the above, 30% by weight of the aromatic hydrocarbon is used.
The method for obtaining the second and fourth light oils including the above is not limited to the above-described embodiment. For example, heavy oil is distilled under reduced pressure without using the atmospheric distillation column 2, and the reduced pressure light oil is hydrotreated. You may do so. In addition, for a part of light oil obtained by distilling crude oil containing a large amount of aromatic hydrocarbons at normal pressure, the aromatic hydrocarbons are decomposed by a nuclear hydrogenation reaction using a noble metal-based hydrogenation catalyst, and the content of aromatic hydrocarbons is reduced. May be obtained, and this may be used as the third light oil mentioned above. Further, the light oil containing less than 30% by weight of an aromatic hydrocarbon may be a light oil obtained by distilling crude oil under reduced pressure, or a light oil obtained by distilling residual oil obtained by atmospheric distillation under reduced pressure. It may be oil.

The gas turbine fuel oil obtained by the present invention is used in a gas turbine combined cycle power generation system. This power generation system will be described with reference to FIG. 4. Gas turbine fuel oil is burned by a combustion nozzle, the gas turbine 201 is driven by the combustion gas, and electric power is extracted from the generator 202. On the other hand, the high-temperature exhaust gas discharged from the gas turbine 201 is supplied to the exhaust heat recovery boiler 203, where steam is generated by the heat of the exhaust gas. This steam allows the steam turbine 20
4 is driven, and electric power is extracted from the generator 205.
If power is generated in this manner, the exhaust heat of the gas turbine fuel oil can be effectively used, and power generation can be performed with high efficiency.
