Black oil

Fuel Company "Rusneftesnab" engaged in the supply of petroleum products on the Russian Federation, and also delivers fuel oil. Supply of fuel is carried put by road transport in Moscow and its neighboring area. JSC "Rusneftesnab" delivers fuel by rail to the regions of the Russian Federation.

Our goali is to  provide our consumers only with a quality petroleum products in the shortest possible time in view of a rational pricing policy.

Fuel oil (from the Arabic mazhulat - rubbish) is a liquid dark brown product, a residium after refinary or  recycling of  gasoline, kerosene and gas oil fractions boiling up to 350 - 360 ° C. Fuel oil is a mixture of hydrocarbons (with a molecular weight from 400 to 1000 g / mol), the petroleum resins (molecular weight 500 - 3000 g / mol and more), asphaltenes, carbenes, karboidov and organic compounds containing metals (V, Ni, Fe, Mg, Na, Ca). Physico-chemical properties of oil depend on the chemical composition of the initial oil and the degree of distillate fractions. Fuel oil is characterised by viscosity 8 - 80 mm / s (at 100 ° C), density of 0.89 - 1 g / cm (at 20 ° C) , pour point 10 - 40 ° C, the sulfur content of 0,5 - 3,5%, ash to 0,3%, the lowest heat of combustion 39,4 - 40,7 MJ / mol.

Heavy oil is used as fuel for steam boilers, boiler plants and industrial furnaces. Production of fuel oil is about 50% by weight in the calculation of the original oil. In view of the need to deepen its further processin, fuel oil in an increasing scale is subjected to further processing, distilling off under vacuum the overhead products, boiling in the range 350 - 420, 350 - 460, 350 - 500 and 420 - 500 ° C. Vacuum distillates are used as feedstock for motor fuels and distillate lubricating oils. Butts of  vacuum distillation of fuel oil  is used for processing in a thermal cracking and coking in the production of residual lube oil and tar, and then processed for bitumen.

Sale and delivery of oil products is made in Russia by road and rail. Delivery of dark fuel (fuel oil) is carried out for industrial enterprises and organizations that use in the manufacture and consume fuel oil, diesel fuel, gasoline, bitumen and other petroleum products.

The main consumers of fuel oil are industry and housing and communal services. In 2005, Russia exported 45.8 million tons of fuel oil at 10.2 billion $. Fuel oil ranks fourth after the oil, gas and diesel fuel in the structure of Russian exports (in monetary terms).

Fuel oil belongs to the group of residual hydrocarbon fractions processed after oil refining. Properties of oil depends on the initial properties of crude oil and its depth of processing at the refinaries. Oil, as the final product of oil refining, contains ballast - incombustible part, consisting of mineral mass, water. In the process of cracking oil, light hydrocarbon fraction, gasoline, kerosene, diesel fuel saturated oil with hydrogen to a greater extent, so the hydrogen content of fuel oil compared to the crude oil decreases, which reduces its calorific value.

Reducing the calorific value of fuel oil is due to increased content in its composition of sulfur, nitrogen, oxygen resin, asphaltene, ash, solids.

Mineral mass of oil has a significant amount of various metals, including vanadium. Vanadium is concentrated in the petroleum resins, asphaltenes, and are the major sulfur-containing components. Vanadium oxides cause a low-temperature and high temperature, at 600-700 ° C, the corrosion of metals, resulting in the destruction of heating surfaces, sealing surfaces of exhaust valve and gas turbine blades.

According to international standards of quality, mineral mass contained in the fuel oil shall not exceed 0,1-0,3%, but despite its small content, produced by burning fuel oil ash, postponing to the heating surfaces of boilers, significantly reduces heat transfer from combustion products . Ash deposits on the surfaces of piston diesel engines cause accelerated wear of the rubbing surfaces, inhibit the transfer of heat to the cooling medium.

Fuel oil quality is changing during transportation and storage in containers. As a result of continuous oxidation and polymerization reactions, hydrocarbon fuel converted into solid products, precipitating.

During cold weather  when rail tanks are being bubble heating, water content in fuel oil may reach 10-15%. During further storage fuel oil  is extra watered with atmospheric moisture. Analises of  quality of fuel oil stored in tanks at one of the petrolium storage depotes show that water content in the samples collected at the level 4-5 m from the bottom reaches 5% and in the bottom layers -12%.

Shipment of oil is carried out by rail directly from the factory-manufacturer. Delivery of fuel by rail is needed to supply industrial enterprises and organizations that use in the manufacture and consume fuel oil, diesel fuel, gasoline, bitumen and other petroleum products.

Bunker companies  heats oil in the containers to a temperature at which is provided by repumping and mixing of fuel oil. Water settling in the high-viscosity fuel oil with high density which has been heated insufficiently, becomes practical impossible, noreover, it is likely to be assumed that the consumers receive too watered oil. The quality of fuel oil may deteriorate during mixing it in the oil storage tanks with fuel oil, which quality characteristics do not meet the standard requirements because of long storage. Different suppliers provede bunker companies with batches of fuel, mixing them by keeping only the quality standards of the viscosity, and do not take into account other indicators. By acting in this way, they are based on international standards of quality, which does not include check of the purification degree from ectogenic inclusions and  stability of fuel, do not determine the current carbon aromatic index / CCAI /, having a strong influence on fuel inflammation. If  the index is more than CCAI 850-890 so fuel inflammation is rapidly deteriorating.

This leads to accidental pollution products of combustion cylinder group, exhaust valves. Unburnt fuel can accumulate in the gas section, which leads to higher combustion pressure, knocking in the cylinders, explosion, fire in the gas section. An increased content of aromatic fractions is most probably for fuel with reduced viscosity from 180 cSt to 220 cSt, obtained by mixing distillated fuels with high-viscosity oil. Sale of fuel oil is  carried out on all over the Russian Federation.
