What is the crude petroleum



is called several names such as: oil, black gold, crude oil, oil can be

defined as a liquid black tends to greenness, and fluid is flammable,

oil exists in the upper layer of the Earth’s crust. Mainly oil and

consists of a complex mixture of hydrocarbons: alkanes series which

is very precious chemically, oil differs in terms of its composition

and its purity and its appearance dramatically depending on where

you extracted the oil from it. The oil is used heavily in several areas

such as: electricity production and operation of equipment used in

the production of electrical energy that can be generated in other

ways provide humanity burning oil, the oil is used also in running

factories and moving transportation means, and is also used in

chemical products, where it is a constituent of these products raw

materials such as fertilizers, pesticides, and fabrics, rayon, artificial

leather, plastics, medicines, these are the benefits and uses of oil

and many others if anything it shows The importance of big oil in

our daily lives, without it you cannot do several important things in

our lives, so it must be maintained because it is an important means

for energy and used in many, many important things.

Ancient geological ages of oil produced because the forest was

heavily deployed throughout the land, aquatic plants and plankton

marine organelles that occurred under layers of Earth, after millions

of years and with increasing pressure on it turned into oil. Stages

and conditions of oil phase formative stage; at this stage must have

oil composition: organic matter, which must be present in high

concentration in layers of rocks and rock called source rocks. The

presence of heat.

Having the right pressure in the depths. This phase is three points o

f terms which are oil. The second phase of the migration stage: the

stage in which oil migrates from where you are from any of the

source rocks high advise passing to other areas less compressed,

which is made by two factors: pressure difference: the force

responsible for moving the oil.

Cracks and fractures in the rocks to allow passage of oil. Third stage:

stage and final stage that work on the oil pool in large quantities, so

there must be oil catch system which works on preventing further

oil migration.


Oil and oil components or the oil output of the landfill organisms

process, is a substance or a viscous liquid and dense textures, color

black tends to greenness, smells like rotten eggs, a flammable

dramatically, mainly consists of a mixture of hydrocarbons, it

contains mainly associating the following elements are described:

Carbon: which constitutes the highest percentage so that up to 85%

-90%. Hydrogen: as a proportion of about 10% to 15%. Oxygen:

which of between zero and 1.5%. Sulfur: which estimated the

proportion of its existence by 0.1% to 3%. Nitrogen: which of

between 0.1% to 5%.

The ratio of oil to the so-called Greek word (BP), which consists of

the first two parts Petra means rock, and oleum second, which

means the oil or fat. With respect to the use of this liquid and

benefit from it, it is impossible to be used immediately after the

crude oil extracted, it needs to undergo a process called (oil

refining), in order to obtain oil derivatives known and that can take

advantage of them.
