We are offering base oil sn 500.Base oil is the name given to lubrication grade oils initially produced from refining crude oil (mineral base oil) or through chemical synthesis (synthetic base oil). Base oil is typically defined as oil with a boiling point range between 550 and 1050 f, consisting of hydrocarbons with 18 to 40 carbon atoms. This oil can be either paraffinic or napthenic in nature depending on the chemical structure of the molecules. Almost every lubricant used in plants today started off as just a base oil. The american petroleum institute (api) has categorized base oils into five categories (api 1509, appendix e). The first three groups are refined from petroleum crude oil. Group iv base oils are full synthetic (polyalphaolefin) oils. Group v is for all other base oils not included in groups I through iv. Before all the additives are added to the mixture, lubricating oils begin as one or more of these five api groups.

Group Ibase oils are classified as less than 90 percent saturates, greater than 0.03 percent sulfur and with a viscosity-index range of 80 to 120. The temperature range for these oils is from 32 to 150 degrees F. Group I base oils are solvent-refined, which is a simpler refining process. This is why they are the cheapest base oils on the market.

Group IIbase oils are defined as being more than 90 percent saturates, less than 0.03 percent sulfur and with a viscosity index of 80 to 120. They are often manufactured by hydrocracking, which is a more complex process than what is used for Group I base oils. Since all the hydrocarbon molecules of these oils are saturated, Group II base oils have better antioxidation properties. They also have a clearer color and cost more in comparison to Group I base oils. Still, Group II base oils are becoming very common on the market today and are priced very close to Group I oils.

Group IIIbase oils are greater than 90 percent saturates, less than 0.03 percent sulfur and have a viscosity index above 120. These oils are refined even more than Group II base oils and generally are severely hydrocracked (higher pressure and heat). This longer process is designed to achieve a purer base oil. Although made from crude oil, Group III base oils are sometimes described as synthesized hydrocarbons. Like Group II base oils, these oils are also becoming more prevalent.

Group IVbase oils are polyalphaolefins (PAOs). These synthetic base oils are made through a process called synthesizing. They have a much broader temperature range and are great for use in extreme cold conditions and high heat applications.

Group Vbase oils are classified as all other base oils, including silicone, phosphate ester, polyalkylene glycol (PAG), polyolester, biolubes, etc. These base oils are at times mixed with other base stocks to enhance the oils properties. An example would be a PAO-based compressor oil that is mixed with a polyolester. Esters are common Group V base oils used in different lubricant formulations to improve the properties of the existing base oil. Ester oils can take more abuse at higher temperatures and will provide superior detergency compared to a PAO synthetic base oil, which in turn increases the hours of use.

Fuel oil is a fraction obtained from petroleum distillation, either as a distillate or a residue. Broadly speaking fuel oil is any liquid petroleum product that is burned in a furnace or boiler for the generation of heat or used in an engine for the generation of power, except oils having a flash point of approximately 40 C (104 F) and oils burned in cotton or wool-wick burners.

The term fuel oil is also used in a stricter sense to refer only to the heaviest commercial fuel that can be obtained from crude oil i.e. heavier than gasoline and naphtha.

The ASTM classification system, originally based on early refining and combustion engineering practices and nomenclature, identifies 6 fuel oil specifications. Different definitions do however exist.

Increases in the fuel oil number signify an increased boiling point and carbon chain length and heavier viscosity. Price usually decreases as the fuel number increases.

• Number 1: a volatile distillate oil intended for vaporizing pot-type burners. It is the kerosene refinery cut that boils off right after the heavy naphtha cut used for gasoline. Older names include coal oil, stove oil and range oil.
• Number 2: a distillate home heating oil. Trucks and some cars use similar diesel fuel with a cetane number limit describing the ignition quality of the fuel. Both are typically obtained from the light gas oil cut.
• Number 3: a distillate oil for burners requiring low-viscosity fuel. ASTM merged this grade into the number 2 specification and the term is rarely used.
• Number 4: a commercial heating oil for burner installations not equipped with preheaters. It may be obtained from the heavy gas oil cut.
• Number 5: a residual-type industrial heating oil requiring preheating to 170 220 F (77 104 C) for proper atomization at the burners. This fuel is sometimes known as Bunker B. It may be obtained from the heavy gas oil cut, or it may be a blend of residual oil with enough number 2 oil to adjust viscosity until it can be pumped without preheating. Also called Navy Special Fuel Oil, Navy Special or Furnace Fuel Oil.
• Number 6: a high-viscosity residual oil requiring preheating to 220 260 F (104 127 C). Residual means the material remaining after the more valuable cuts of crude oil have boiled off. The residue may contain various undesirable impurities including 2 percent water and one-half percent mineral soil. This fuel may be known as residual fuel oil (RFO), by the Navy specification of Bunker C, or by the Pacific Specification of PS-400. Also called Furnace Fuel Oil.
• Mazut:a residual fuel oil often derived from Russian petroleum sources and is either blended with lighter petroleum fractions or burned directly in specialized boilers and furnaces. It is also used as a petrochemical feedstock.

Bunker Fuels

Bunker fuels are also a type of fuel oil, used aboard ships. Bunker fuel is often used as a synonym for No. 6 fuel oil which is the most common bunker fuel.

• Bunker A:No. 2 fuel oil
• Bunker B:No. 4 or 5 fuel oil
• Bunker C: No. 6 fuel oil

Marine Fuels

Other types of classification used in the maritime field also include :

• HFO: Heavy Fuel Oil - pure or nearly pure residual oil, roughly equivalent to No. 6 fuel oil
• IFO: Intermediate Fuel Oil - a blend of gasoil and heavy fuel oil, with less gasoil than marine diesel oil.
• MDO: Marine Diesel Oil - a blend of heavy gasoil that may contain very small amounts of black refinery feed stocks, but has a low viscosity up to 12 cSt so it need not be heated for use in internal combustion engines
• MFO: Marine Fuel Oil - same as HFO
• MGO: Marine Gas Oil - roughly equivalent to No. 2 fuel oil, made from distillate only

Marine fuels are often quoted on the international bunker markets with their maximum viscosity (which is set by the ISO 8217 standard) due to the fact that marine engines are designed to use different viscosities of fuel. The unit of viscosity used is the Centistoke and the fuels most frequently quoted are listed below in order of cost, the least expensive first :

• IFO380: Intermediate fuel oil with a maximum viscosity of 380 Centistokes (

The fertilizers outlined here are compound fertilizers composed of primary fertilizers and secondary nutrients. These represent only one type of fertilizer, and other single nutrient types are also made. The raw materials, in solid form, can be supplied to fertilizer manufacturers in bulk quantities of thousands of tons, drum quantities, or in metal drums and bag containers.

Primary fertilizers include substances derived from nitrogen, phosphorus, and potassium. Various raw materials are used to produce these compounds. When ammonia is used as the nitrogen source in a fertilizer, one method of synthetic production requires the use of natural gas and air. The phosphorus component is made using sulfur, coal, and phosphate rock. The potassium source comes from potassium chloride, a primary component of potash.

Secondary nutrients are added to some fertilizers to help make them more effective. Calcium is obtained from limestone, which contains calcium carbonate, calcium sulphate, and calcium magnesium carbonate. The magnesium source in fertilizers is derived from dolomite. Sulfur is another material that is mined and added to fertilizers. Other mined materials include iron from ferrous sulfate, copper, and molybdenum from molybdenum oxide.

We are offering bitumen vg40.Viscosity grading can be done on original (as-supplied) asphalt binder samples (called ac grading) or aged residue samples (called ar grading). The ar viscosity test is based on the viscosity of aged residue from the rolling thin film oven test. With ac grading, the asphalt binder is characterized by the properties it possesses before it undergoes the hma manufacturing process. The ar grading system is an attempt to simulate asphalt binder properties after it undergoes a typical hma manufacturing process and thus, it should be more representative of how asphalt binder behaves in hma pavements.advantages: unlike penetration depth, viscosity is a fundamental engineering parameter.Testing equipment and standards are widely available.Temperature susceptibility can be determined because viscosity is measured at three different temperatures.
