Description

The invention relates to the field of liquid hydrocarbon fuel compositions for ship high-speed diesel engines, ship gas turbines and ship boilers and can be used year-round mainly on displacement (constantly afloat) ships and, if necessary, on commercial ships.

Currently, in accordance with GOST RV 50920 “Fuels, oils, greases and special fluids. The restrictive list and appointment procedure for armaments and military equipment ”on ships with boiler power plants, mixed fuel (fuel oil F5 according to GOST 10585) is used, consisting of residual components of oil refining (fuel oil, tar) and distillate components as primary oil refining (diesel fuel, vacuum gas oil), and the secondary processing of oil fractions (light gas oil catalytic or thermal cracking).

On ships with high-speed diesel engines (crankshaft revolutions up to 2200 min ^-1 ) and gas turbine (working gas temperature 1000 ° С and more) installations, L-0.2-62 diesel fuel is used in accordance with GOST 305, consisting of hydrotreated oil fractions, 96% about. which boil up to 360 ° C.

The use of fuel oil on these types of power plants is impossible due to its unacceptably high coking ability (up to 6%), ash content (up to 0.05%) and the content of corrosive metals (vanadium, sodium, lead, etc.), which manifest themselves in the high-temperature region - in combustion products (BV Losikov et al. Fuels for stationary and ship gas turbines. X., M, 1970, pp. 81-92. Express information "Transport and storage of oil and gas", 1969, No. 44, p .9-16).

The use of F5 fuel oil is also undesirable on ships with boiler power plants due to the inevitable deterioration of their combat readiness due to the need for frequent cleaning of the heating surfaces of boiler units, during which they are decommissioned, and the ship cannot provide maximum speed. Corrosive-aggressive metals in the combustion products systematically lead to the failure of spacecraft elements (in particular, steam generating tubes), which requires repair of the spacecraft.

Due to the development of modern means of detecting ships at sea by the presence of hot soot particles of incomplete combustion of fuel oil with increased thermal radiation, as well as due to contamination by the combustion products of optical and radar devices located on the upper deck of ships, their vulnerability to enemy attacks increases on the contrary, the ability to detect an adversary decreases.

The combat readiness of ships is also reduced due to precipitation from fuel oil during storage in the tanks of the ship. These sediments are composed of solids, asphaltenes, carbenes, carbides and paraffins. Poor demulsifying properties (long-term retention of water in the fuel mass, including in the form of "nests", the ingress of which when the fuel is supplied to the combustion leads to the decay of the combustion torch, and sometimes to "explosions" in the furnace due to the sharp evaporation of a large amount of water ), which leads to a decrease in speed or the need for repair. The low refueling speed (especially on the go) due to the high viscosity and the associated limitation of the maneuverability of the ship makes it more vulnerable to enemy attacks.

The elimination of these drawbacks is possible only if the use of fuel oil is excluded and instead of fuel oil is used on displacement ships with all three types of power plants (boiler, diesel and gas turbine) distillate fuel, which should be developed and become universal.

The highest requirements for fuel are diesel engines. These requirements are satisfied by diesel fuel L-0.2-62 according to GOST 305. However, it has limited resources, since it includes only hydrotreated fractions of direct distillation of oil boiling up to 360 ° С. With regard to use on ships, it has overestimated low-temperature properties (in particular, the cloud point is not higher than minus 5 ° С). The lowest ambient temperature for displacement ships can be 0 ° С (sea water temperature in winter), which makes it possible to increase the cloud point of distillate fuel for ships to minus 1 ° С, which, in turn, allows distillate fractions to be involved in the fuel fuel oil, which expands fuel resources.

The process of fuel combustion in a diesel engine is controlled only by the level of the minimum cetane number (cetane index). Both of these indicators are equivalent for fuels without cetane-raising additives, which include fuels for displacement ships. However, practice shows that excessively large values of the cetane index for fuels, especially fuels containing fractions with a boiling point of 96% vol. more than 360 ° C are also unacceptable. According to experience, the cetane index should not exceed the optimal cetane index by more than 5 units. It is desirable that the specified excess be as close as possible to a zero value, i.e. so that the fuel has a cetane index equal to the optimal cetane index. This requirement (excess of the cetane index over the optimal one) must be satisfied by the developed unified distillate fuel. More than 5 units. the magnitude of this excess leads to delayed combustion, which increases the specific consumption and smoke of the exhaust gas of the fuel, i.e. deterioration in fuel economy and its environmental performance. If the specified cetane indices are excessively large (15 units or more), an engine failure is likely due to soot clogging of the piston grooves and subsequent pinching of the piston rings in the engine cylinder. This is also facilitated by the increase in friction between the piston and the cylinder bushing due to burning of a film of lubricating oil by a long-lasting flame with slowly burning fuel.

Other requirements that the developed fuel must satisfy include the following restrictions: by mass fraction of sulfur - the maximum value of "not more than 0.5%" for the allowable amount of engine wear; in terms of fuel density - within the range of "853-862 kg / m ³ " to maintain acceptable "stability" of the ship when replacing heavy fuel oil with fuel with a lower density and in oxidative stability - "not higher than 2.5 mg of sediment per 100 cm ^{3 of} fuel" accelerated method (GOST R EN ISO 12205) to ensure the life of the filter elements of fuel systems before cleaning them.

The authors were faced with the task of developing a fuel suitable for year-round use on all three types of power plants of ships (boiler rooms, diesel and gas turbine), which will significantly increase the combat readiness of ships and will contribute to meeting the requirements of the President of Russia set forth in the article by Vladimir Putin “To be strong - a guarantee of national security for Russia ”(Russian newspaper, issue 5708 of 02.17.2012). He said: “We have adopted and are implementing unprecedented programs for the development of the Armed Forces and the modernization of the military-industrial complex of Russia. In Russia. In total, in the coming decade, about 23 trillion rubles will be allocated for these purposes. ”

Based on the above, the fuel must be distillate and meet the following requirements for the main performance indicators:

density at 20 ° C - 853-862 kg / m ³ ;

cloud point - not higher than minus 1 ° С;

mass fraction of sulfur - not more than 0.5%;

cetane and optimal cetane indices - not less than 45 units;

excess of cetane index over optimal - from 0 to 5 units;

precipitate during accelerated aging - not more than 2.5 mg / 100 cm ³ .

It is also desirable that the sediment in oxidized fuel contains (% wt.) As many fine particles as possible (up to 0.5 μm in size) in the total precipitate released by sequential filtration through membrane filters No. 6 (pore size 3.5 μm) and No. 2 (pore size 0.5 μm).

When viewing the patent and scientific and technical information, the authors identified technical solutions that partially ensure the fulfillment of the task.

Known fuel composition (low-viscosity marine fuel) containing (% wt.):

Straight run fraction (atmospheric gas oil),

boiling off at 240-450 ° С 5-15 The first vacuum run 200-400 ° C 5-25 Coking gas oil 160-400 ° C 5-30 Catalytic cracking gas oil 180-400 ° C 5-60 Diesel fuel 160-360 ° C Up to 100

(RF patent No. 207 6138, C10L 1/04, 1997).

The disadvantages of the composition are its high coking ability (0.2% wt.), High sulfur content (up to 1.5% wt.), Low cetane number (40 units), which does not allow its use in high-speed diesel engines of displacement ships.

Also known is a composition for a single marine fuel for power plants, containing (% wt.):

Vacuum fractions of fuel oil with temperature boiling 96% vol. up to 450 ° C 17-25 Hydrotreated Diesel Mixture and light catalytic cracking gas oil, taken before hydrotreating in a ratio of 1.5: 1 up to 100

(TU 38.101717-78. "Single fuel for marine power plants of naval facilities").

The disadvantages of the composition are its relatively low storage stability compared to diesel fuel and the low dispersion of the precipitate formed (a relatively large proportion of large particles in it) identified during storage. These shortcomings lead to the formation of a large amount of sediment on the bottoms of the tanks, and when supplied to the engine, severe clogging of the filter elements of the fuel systems.

The closest in technical essence, taken as a prototype, is a fuel composition for ship high-speed diesel engines and gas turbines, including vacuum fractions of fuel oil with a boiling point up to 450 ° C and a hydrotreated mixture of diesel fuel and light catalytic cracking gas oil, taken before hydrotreating in the ratio of 1, 5: 1, 8-hydroxyquinoline and additive C-5A in the following ratio of components, wt.%:

Vacuum fractions of fuel oil with temperature boiling 96% vol. up to 450 ° C 17-25 Reagent 8-hydroxyquinoline 0.0045-0.0105 Additive S-5A 0.0015-0.0035 Hydrotreated mixture of diesel fuel and light catalytic cracked gas oil, taken before hydrotreating in a ratio of 1.5: 1 up to 100

(RF patent No. 2305126, C10L 1/18, C10L 1/24, 2006).

The disadvantages of the composition are the limited temperature range of application, due to the fact that it contains fractions of fuel oil with an excessively high boiling point (96% vol. - 450 ° C), as well as the difficulties of its production in oil refineries (refineries) associated with accuracy 1.5: 1 ratio of diesel fraction and light catalytic cracking gas oil before hydrotreating. It is the need to fulfill this condition that makes it unprofitable to produce the specified fuel composition at the refinery, since the amount of light catalytic cracking gas oil produced is insufficient to obtain the required mixture with diesel fraction to ensure a continuous hydrotreatment process with a full load of the hydrotreatment unit. As a result, the hydrotreatment unit can continuously work only with reduced productivity or stand idle, which is unacceptable for refineries.

The presence of a fuel oil fraction with a boiling point up to 450 ° C leads to the release of solid paraffin crystals from the fuel composition even at a temperature of 7 ° C, increasing their number with a further decrease in temperature. Since ship’s tanks (unlike commercial vessels) are not equipped with fuel heating means, the use of this fuel composition on ships all year round, in particular in the cold season (at temperatures below 7 ° C) is impossible due to clogging of filter elements with hard paraffins.

The technical result of the invention is to increase the level of operational properties of the fuel composition while maintaining the nominal performance of the units at the refinery without disrupting the process of their work.

The specified technical result is achieved in that the fuel composition for displacement ships containing vacuum fractions of fuel oil, light catalytic cracking gas oil, reagent 8-hydroxyquinoline, dispersant additive and hydrotreated diesel fuel, according to the invention, as vacuum fractions of fuel oil contains a light vacuum overhead fuel oil with a boiling point 96% vol. up to 400 ° C, non-cleaned light gas oil of catalytic cracking and as a dispersing additive - additive C-40 in the following ratio of components,% mass .:

Light vacuum overhead oil with temperature boiling 96% vol. up to 400 ° C 11-16 Non-cleaned light gas oil catalytic cracking 4-19 Reagent 8-hydroxyquinoline 0.0020-0.0075 Dispersing additive S-40 0.0004-0.0015 Hydrotreated Diesel Rest

and also the fact that at a density at 20 ° C of a light vacuum overhead of fuel oil with a boiling point of 96% vol. up to 400 ° С equal to (892 ± 4) kg / m ³ , and at a density at 20 ° С of non-hydrotreated light catalytic cracking gas oil equal to (975 ± 2) kg / m ³ , their content in the fuel composition is,% of the mass, “No more than 14” and “no more than 9”, respectively, and at a density at 20 ° C of a light vacuum overhead of fuel oil with a boiling point of 96% vol. up to 400 ° С equal to (883 ± 3) kg / m, and at a density at 20 ° С of non-hydrotreated light catalytic cracking gas oil equal to (935 ± 4) kg / m ³ , their content in the fuel composition is,% wt., “Not less than 14” and “not less than 17”, respectively.

Light vacuum overhead fuel oil with a boiling point of 96% vol. up to 400 ° C is a fraction of fuel oil, boiling in the temperature range from 270-330 ° C to 375-405 ° C, obtained by distillation of fuel oil at a distillation column of a refinery operating under reduced pressure (under vacuum).

Non-hydrotreated light gas oil of catalytic cracking is a hydrocarbon fraction boiling in the temperature range from 200-230 ° C to 325-360 ° C, obtained by distillation distillation of the products of catalytic cracking of a mixture of vacuum fuel oil straps boiling in the range from 270-330 ° C to 500- 550 ° C.

As practice has shown, the density (kg / m ³ at 20 ° C) of these components obtained at different refineries is different and depends on the quality of the refined oils and the characteristics of the plant’s process units. For the Slavneft-YANOS refinery, the components produced have a density at 20 ° C: of light vacuum overhead fuel oil with a boiling point of 96% vol. up to 400 ° С - (883 ± 3) kg / m ³ ; non-cleaned light catalytic cracking gas oil - (935 ± 4) kg / m ³ For the Ryazan Oil Refining Company CJSC, the components produced have a density at 20 ° C: a light vacuum overhead with a boiling point of 96% vol. up to 400 ° С - (892 ± 4) kg / m ³ ; non-hydrotreated light catalytic cracking gas oil - (975 ± 2) kg / m ³ .

The reagent 8-hydroxyquinoline is manufactured according to GOST 5877 and is a light yellow crystals with a melting point of 75-76 ° C and a molecular weight of 145.16. It is widely used, in particular, as an analytical reagent, in the production of antiseptics in medicine, as a reagent in the determination and separation of metals (Al, Zn, Cd, Mg, etc.). The reagent has antioxidant properties and is able to prevent the formation of sludge during storage of fuels weighted fractional composition.

Additive S-40 is manufactured according to TU 0257-104-40065452-2006 "Additive succinimide S-40" and is a solution (40-50 wt.%) Of polyisobutenyl succinimide polyethylene polyamine in industrial oil I-20. The viscosity of the kinematic additive at 100 ° C is "not more than 500 mm ² / s", the mass fraction of nitrogen,% - "not less than 1.2", the flash point, ° C - "not lower than 180". The additive is used as a dispersant in motor oils.

Hydrotreated diesel fuel. An oil fraction is obtained boiling in the temperature range from 190-200 ° C to 360 ° C during the distillation of oil on a distillation column operating at atomospheric pressure. Then this fraction is subjected to hydrotreating to reduce the mass fraction of sulfur to a level of less than 0.2%. The result is a component "hydrotreated diesel fuel", which is included in the inventive fuel composition.

The obtained samples were laboratory tested in the amount of requirements for the main performance indicators of the claimed fuel composition, the results of which are shown in table 2.

From the data given in tables 1 and 2, it follows that the output of the component composition from the declared limits leads to an unacceptable decrease in operational properties.

So, for samples No. 1, No. 2 and No. 7 (table 1, columns 2, 3 and 8; table 2, columns 3, 4 and 9) with a lower content of components than stated, the density of the fuel decreases to an unacceptable level (respectively 852, 838 and 851 kg / m ³ instead of the required “853-862 kg / m ³ ”) and the sediment increases with accelerated aging of the fuel (2.8, 2.9 and 3.3 mg / 100 cm ^3, respectively, instead of the required “not more than 2.5 mg / 100 cm ³ "). The precipitate during accelerated aging in a fuel containing more additives of 8-hydroxyquinoline and C-40 than in the declared amount - samples 9 and 12 (table 1, columns 10 and 13; table 2, columns 11 and 14), practically does not decrease, t .e. an increase in the number of additives in excess of the declared is unjustified.

The presence in the fuel composition of additives 8-hydroxyquinoline and C-40 in the declared amount (% wt.), I.e. 0.0020-0.0075 and 0.0004-0.0015, respectively, provides the amount of sediment in an acceptable amount (not more than 2.5 mg / 100 cm ³ ) - samples No. 3, 4, 5, 6, 8, 10 , eleven.

Exceeding the content of components over the declared limit (samples No. 9 and No. 12 table 1, columns 10 and 13; table 2, columns 11 and 14) leads to unacceptable values of the density at 20 ° C (864 kg / m ³ instead of "853-862 kg / m ³ ”), mass fraction of sulfur (0.51% instead of“ no more than 0.50 ”) and excess of the cetane index over the optimum (minus 0.5 and minus 0.3 instead of“ from 0 to 5 ”).

According to the test results of the samples, an experimental batch of the inventive fuel composition according to sample No. 11 was prepared, which was tested by laboratory methods in comparison with the composition of the prototype and the composition of hydrotreated diesel fuel in accordance with the regulatory documentation for the tests, and the possibility of its production at the refinery during operation was evaluated installations with full performance. The test results are shown in table 3.

As follows from the data in table 3, the inventive fuel composition has advantages over the prototype cetane index (47.7 and 46.5) - it has better flammability in diesel engines, i.e. better starting properties of fuel; by the excess of the cetane index over the optimal (0.1 instead of 1.3 units) - the best approximation to the zero value of the excess of the cetane index over the optimal cetane index, which reduces the specific consumption and smoke of the exhaust gases; at the cloud point (minus 3 ° C instead of 7 ° C), which makes it possible to use it year-round without the need to install fuel heaters in each tank of the ship to prevent the release of solid paraffins at temperatures below 7 ° C and to ensure the production of fuel at refineries without changing technological plant operation processes (see p.6 of the present description).

The inventive fuel composition (sample 11) has an advantage over the base fuel (diesel fuel L-0.2-62 according to GOST 305) in terms of the optimality of the combustion process (excess of the cetane index over the optimal 0.1 units and 9.3 units, respectively) . This provides a lower specific consumption of the inventive fuel composition, i.e. increases its efficiency, and reduces the smoke of exhaust gases, i.e. improves its ecological properties.

Confirmation that the specific consumption and smoke of the exhaust gases depend on the value of the cetane number (cetane index) of the fuel are the data given in the article by L.V. Malyavinsky and V.M. Russian "Study of the effect of cetane number of diesel fuels on engine performance" (Chemistry and technology of fuels and oils, 1976, No. 2, p. 45-46). According to the article, diesel fuel DL according to GOST 4749-73 with a cetane number of 45 units. in comparison with diesel fuel, DS according to the same GOST with a cetane number of 51 has a lower specific consumption (by 2.9% mass.) and exhaust smoke (by 13.3% in units of the Hartridge device) when tested on a YaM3-236 engine ), and when tested on a D-20 engine - by 3-3.5% and 30-40%, respectively.

The excess of the cetane index over the optimum (table 3 p. 6) for the inventive fuel composition has a value of 0.1 units, and for diesel fuel L-0.2-62 according to GOST 305 - 9.3 units. This means an even greater advantage (than for the fuels given in the article) of the claimed fuel composition over the base fuel in terms of specific consumption and exhaust smoke.

The large volumetric heat of combustion (table 3 p. 7) of the claimed fuel composition relative to the base fuel by 2.5% (36.4 and 35.5 MJ / dm ³ ) increases the range of the ship without refueling by 2.5%. An additional (in excess of 2.5%) increase in range will also occur due to lower specific fuel consumption, which follows from the data in this article and the test results for the indicator "excess of cetane index over optimal cetane index" of the claimed fuel composition and base fuel given in table 3 p. 6.

The developed fuel composition is completely distillate (see p. 9-10 of the present description), i.e. free from the disadvantages of fuel oil, leading to a decrease in the combat readiness of ships with boiler units (see p. 2 of this description).

Thus, the inventive fuel composition meets the requirements posed by the authors (see task to the authors, pp. 4-5 of the present description) and provides a technical result of the invention (improving the operational properties of the fuel composition while maintaining the nominal performance of refinery units without disrupting the process process of their work) only in the claimed range of component ratios.

The application of the invention will ensure year-round use of the fuel composition for displacement ships by lowering the cloud point from 7 ° C (in the prototype) to minus 1 ° C, as well as the possibility of its manufacture at a refinery without reducing the productivity of the plants. Increasing the range of the ship without refueling and reducing the smoke of exhaust gases when burning fuel in power plants will increase the combat readiness of ships, which meets the requirements of the President of Russia to strengthen the Armed Forces of the country.
