What are properties of furnace oil?
What are properties of furnace oil?
They generally have a kerosene-like odor and are flammable. Fuel oils are composed of complex and variable mixtures of aliphatic (alkanes, alkenes, cycloalkanes) and aromatic hydrocarbons, containing low percentages of sulfur, nitrogen, and oxygen compounds.
What are the chemical properties of engine oil?
3.1 CHEMICAL IDENTITY The oil is typically 73-80% weight/weight aliphatic hydrocarbons (primarily alkanes and cycloalkanes with l-6 rings); 11-15% monoaromatic hydrocarbons; 2-5% diaromatic hydrocarbons; and 4-8% polyaromatic hydrocarbons (Vasquez-Duhalt 1989).
What are physical properties of oil?
The most common physical properties used to describe petroleum are density, viscosity, and boiling point ranges. The density of crude oils is usually expressed as API (American Petroleum Institute) gravity, which is inversely related to specific density.
What is chemical fuel What are the properties of a good fuel?
A good fuel should satisfy the following requirements: It should have a high calorific value i.e., it should evolve a large amount of heat when it is burnt. Its moisture content should be low so that its heating value should be high. An ideal fuel should have moderate ignition temperature.
What are the chemical properties of fuels?
The so-called chemical elementary analysis shows that generally fuel oils consist of about 85 to 90% of carbon, 13 to 8% of hydrogen and a small percentage of sulphur, oxygen and nitrogen, but two fuel oils of the same elementary analysis may behave in quite a different manner in burning practice, so that this chemical …
What is the chemical composition of lubricants?
Lubricating oils are composed of 80–90% petroleum hydrocarbon distillate with 10–20% additives to impart specific properties to the oil. The petroleum hydrocarbon distillate generally consists of paraffinic or naphthenic compounds, whose properties are listed in Table 1.
What is the chemical name of oil?
Its chemical formula, C8H18, reflects the fact that each of the carbons is covalently bonded to one or two of the other carbon atoms and two to three hydrogen atoms. Octane burns really efficiently, so having more octane is good.
What is one chemical property of the products that come from crude oil?
Crude oils also contain a great variety of heteroatomic chemical constituents, comprising of sulphur, oxygen, carbondioxide, nitrogen and trace metals. Nitrogen varies from 0.01 to 2% as dissolved gas in the crude oil (Levinson, 1974). Oxygen occurs in different forms in oxygen-bearing resinous substances.
What are 5 chemical properties examples?
Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. Iron, for example, combines with oxygen in the presence of water to form rust; chromium does not oxidize (Figure 2).
What are the physical properties of oil?
Physical properties of Oil. Viscosity- the viscosity of an oil is a measure of the oil’s resistance to shear. Viscosity is more commonly known as resistance to flow. High viscosity implies a high resistance to flow while a low viscosity indicates a low resistance to flow.
What is the composition of fuel oil?
All fuel oils consist of complex mixtures of aliphatic and aromatic hydrocarbons. The aliphatic alkanes (paraffins) and cycloalkanes (naphthenes) are hydrogen saturated and compose approximately 80-90% of the fuel oils. Aromatics (e.g., benzene) and olefins (e.g., styrene and indene) compose 10-20% and l%, respectively, of the fuel oils.
What is the viscosity of oil?
Viscosity- the viscosity of an oil is a measure of the oil’s resistance to shear. Viscosity is more commonly known as resistance to flow. High viscosity implies a high resistance to flow while a low viscosity indicates a low resistance to flow.
