LNG is a colorless, odorless substance with a density of 0.41-0.5 kg / l. It is influenced by alkanes (it is 0.41kg / l),. Non-toxic.
The boiling point is –158 ... –163 ° C. Modern LNG consists of 85-95% methane, and the remaining 5% consists of ethane, propane, butane, and nitrogen. The lower limit of heat of combustion is 50.116 kJ / kg, or 20 MJ / l. During the processing of sulfuric acid carbon dioxide, etc.
Our company offers supplies of road bitumen of various categories practically throughout the entire Russian Federation.Constantly increasing requirements for road surface, as well as requirements related to the increase in its service life are one of the main requirements for the quality of bitumen today.
The Company produces standard bitumen grades pursuant to GOST 2245-90. Though, constant upgrade of pavement quality requirements, and increase of timing period between road general repairs – increase quality requirements for bitumen production processes. Currently Alrosa-Gaz is implementing modernization program of all bitumen production facilities pursuant to the national standard GOST 33133-2014.
Mazut is a set of hydrocarbons (with a molecular weight of from 400 to 1000), petroleum resins (with a molecular weight of 500-3000 or more), asphaltenes, carbenes, carboids and organic compounds containing metals (V, Ni, Fe, Mg, Na , Ca).
EN 590 is a standard according to the European Committee for Standardization, which lists the physical properties of diesel fuel intended for vehicles in the case of sales in the European Union and other European regions.
Urals is a Russian brand of export oil blend. It is obtained by mixing in the pipeline system of Transneft heavy, high-sulfur oil of the Urals and the Volga region (the sulfur content of which reaches 3.0%, and the density in API degrees does not exceed 26-28) with light West Siberian oil Siberian Light API degrees, sulfur content 0.57%).
The total sulfur content in Urals oil should be no more than 1.2-1.4%, API gravity - 31-32 (or 860–871 kg / m³). The Brent and WTI grades have a density of 38–40 ° API and a sulfur content of no more than 0.2–0.4%, while the Middle Eastern oil of the Oman and Dubai grades maintains a density of 30–33 ° API, the presence of sulfur is 1.1–2.1% . The total supplies of Urals (about 3 million barrels per day) and ESPO (1 million) are quite large and, according to 2018 estimates, exceed the supply of marker varieties BFOE (Brent), Oman, Dubai. Urals is a high-sulfur oil grade (sulfur content of about 1.3%), which is a mixture of oil produced in the Khanty-Mansiysk and Yamalo-Nenets Autonomous Districts, Bashkortostan, Tatarstan and the Samara Region. The main producers of Urals oil are companies Rosneft, Bashneft, Lukoil, Surgutneftegaz, Gazprom Neft, TNK-BP and Tatneft.
Jet fuel is kerosene, not a distillate, such as Gasoil / Diesel. At the refinery, it is separated from gasoline and paraffin. Jet A-1 is widely used as the main fuel worldwide. The difference of this fuel from the Russian analogue TS-1 is in thermo-oxidative stability, which, in turn, is related to the content of mercaptan sulfur in raw materials.
For Jet A-1, a lower content of sulfur is allowed. According to the new standards, the sulfur content should be equalized. The second important component is the corrosive activity of this fuel. Jet A-1 has a flashpoint above 38 ° C (100 ° F) at an auto-ignition temperature of 210 ° C (410 ° F). At the same time, the freezing temperature is at the level of Jet A-1 is -47 ° C (-53 ° F)
CCAI and CII are the abbreviations responsible for the quality of residual fuel oil ignition. Marine fuel in international markets is still the fuel with the highest viscosity standard.
The unit of viscosity is Centistoke. Popular fuels having a viscosity in accordance with ISO 8217 standards based on D6 are as follows: * IFO 380 - intermediate diesel fuel d6 with a maximum viscosity of 380 Centistokes * IFO 180 - intermediate diesel fuel d6 with a maximum viscosity of 180 Centistokes * LS 380 - low sulfur fuel oil (<1.5%) of intermediate d6 with a maximum viscosity of 380 Centistokes * LS 180 - low-sulfur (<1.5%) intermediate diesel fuel d6 with a maximum viscosity of 180 Centistokes * MDO - marine diesel oil. * MGO - marine gas oil.
