Characteristics & Uses Of Petroleum

Products By Engr. FAISAL KAREEM

Products which are obtained from crude oil

Petroleum products are obtained throughfractional distillation of crude oil

characterized by their boiling points and molecular weights

What are Petroleum Products ?

Fractionating Column

Petroleum fuels should ignite and burn easilyand release their energy completely. Hydrocarbons Volatility Impurities Fuel Microbes Octane Volatility Flamibility

Characteristics Of PetroleumProducts

Gasoline contains hydrocarbons in the range of (C4-C10)

kerosene and aviation fuels in (C4-C19) range

diesel fuels can be found in the (C8-C21) range.

Other more heavier hydrocarbons are heating oils found in range of (C15-C22)

lubrication and hydraulic fluids are in the range of C20-C60

Hydrocarbons

Our well know fuels are combined of a number of different hydrocarbon compounds formulated to meet specific properties for an application.

Lighter fuels as gasoline are more volatile than JET or diesel fuels at the same temperature and pressure

Volatility

Refined fuels contain a number of impurities like gums, metals, microbial growth, sediment, sulfur and water

Impurities

As fuel is sterilized when it leaves the refinery, microbial growth occurs after fuel comes into contact with air and water

Biocide additives are needed to encounter such problems

Fuel Microbes

Gasoline fuels are rated with a octane number and this is an indication of their resistance against detonation (knocking)

The higher the rating the more resistant. A high rating does not imply more power but that the fuel can be used in higher compression or turbo supercharged engines

Octane No

Relates to a liquids boiling point and its tendency to evaporate at normal ambient temperatures and pressures

Volatility

Indicates how readily a fuel will start to burn, very helpful in an engine combustion chamber after the spark plug creates a spark.

Flammability

Petroleumm Products are used for various Purpose
