what are the components of petroleum
What do you think would happen if a person did not consider the impact of his or her decision? In addition to cracked naphtha for making petrol, hydrocracking yields light gases useful for refinery fuel, or alkylation as well as components for high quality fuel oils, lube oils and petrochemical feedstocks.

Density of oil is determined by the length of the hydrocarbons it contains. If it contains a great deal of long-chain hydrocarbons, the petroleum will be denser. If it contains a greater proportion of short-chain hydrocarbons it will be less dense. Besides chain length, the ratio of carbon to hydrogen also helps to determine the density of a particular hydrocarbon. The greater the amount of hydrogen in relation to carbon, the lighter the hydrocarbon will be.

Pechelbronn Pitch fountain is said to be the first European site where petroleum has been explored and used.


Te still active Erdpechquelle, a spring where petroleum appears mixed with water has been used sincee. Oil sands have been mined since the 18th century.

Scottish chemist James Young noticed a natural petroleum seepage in the Riddings colliery at AlfretonDerbyshire from which he distilled componenfs light thin oil suitable for use as lamp oil, at the same "what are" obtaining a thicker oil suitable for lubricating machinery.

In Young set up a small pteroleum refining the crude oil.

Young eventually succeeded, by distilling cannel coal at a low heat, in creating a fluid resembling petroleum, which when treated in the same way as the seep oil gave similar products. Young found that by slow distillation he could obtain a number of useful liquids from it, one of which he named "paraffine oil" because at low temperatures it congealed into a substance resembling paraffin wax.

The production of these oils and solid paraffin wax from coal formed the subject of his patent dated 17 October The demand for petroleum as a fuel for lighting in North America and around the world quickly grew. Drake's well is probably singled out because it was drilled, not dug; because it used a steam engine; because there was a company associated with it; and because it touched off a major boom.

A group directed by Major Alexeyev of the Bakinskii Corps whag Mining Engineers hand-drilled a what are in the Baku region in Romania is the first country in the world to have had its annual crude oil output officially recorded in international statistics: The first commercial oil well in Canada became operational in at Oil Springs, Ontario then Canada West.

Advances in drilling continued into when local driller Shaw reached a depth of 62 metres using the spring-pole drilling method.

Access to oil was and still is a major factor in several military conflicts petrolum the twentieth century, including World War IIduring which oil facilities were a major strategic asset and were extensively bombed. As petroleum production in the US peaked during the s, however, the United States was surpassed by Saudi Arabia pefroleum the Soviet Union.

Today, about 90 percent of vehicular fuel needs are met by oil. Petroleum also makes up 40 percent of total energy consumption in the United States, but is responsible petrolum only 1 percent of electricity generation. Viability of the oil commodity is controlled by several key parameters, number of vehicles in the world competing for petroleum, quantity of oil exported to the world market Export Land ModelNet Energy Gain economically useful energy provided minus energy compohentspolitical stability of oil exporting nations and ability to defend oil supply lines.

What is the Petroleum Industry?

The top petroleum oil producing countries are Russia, Saudi Arabia and the United States. Saudi ArabiaUAEIraqQatar and Kuwait. A large portion of the world's total oil exists as unconventional sources, such ghe bitumen in Canada and extra heavy oil in Venezuela.

While significant volumes of oil are extracted from oil sands, particularly in Canada, logistical and technical hurdles remain, as oil extraction requires large amounts of heat and water, making its net energy content quite low relative to conventional crude oil.

Thus, Canada's oil sands are not expected to provide more than a few million barrels per day in the foreseeable future. In its strictest sense, petroleum includes only crude oil, but in component usage it includes all liquid, gaseous and solid hydrocarbons. Residue from this reaction is mixed again with hydrogen, reheated, and sent to a second reactor for further cracking under higher temperatures and pressures.

The Classification of Petroleum

In addition to cracked naphtha for making petrol, hydrocracking yields light gases useful for refinery fuel, or alkylation as well as components for high quality fuel oils, lube oils and petrochemical feedstocks. Following the cracking processes it is necessary to build or rearrange some of the lighter hydrocarbon molecules into high quality petrol or jet fuel blending components or into petrochemicals.

The former can be achieved by several chemical process such as alkylation and isomerisation. Olefins such as propylene and butylene are produced by catalytic and thermal cracking. Alkylation refers to the petroleum bonding of these light molecules with isobutane to form larger branched-chain molecules isoparaffins that make high octane petrol.

Olefins and isobutane are mixed with an acid catalyst and cooled. They react to form alkylate, plus some normal butane, isobutane and propane. The resulting liquid is neutralised and separated in a series of distillation columns.

Isobutane is recycled as feed and butane and propane sold as liquid petroleum gas LPG. Isomerisation refers to chemical rearrangement of straight-chain hydrocarbons paraffinsso that they contain branches attached to the main chain isoparaffins.

This is done for two reasons:. Isomerisation is achieved by mixing normal butane with a little hydrogen and chloride and allowed to react in the presence of a catalyst to form isobutane, plus a small amount of normal butane and some lighter gases. Products are separated in a fractionator. The lighter gases are used as refinery fuel and the butane recycled as feed.

Pentanes and hexanes are the lighter components of petrol. Isomerisation can be used to improve petrol quality by converting these hydrocarbons to higher octane isomers. The process is the same as for butane isomerisation. Under pressure and temperature, over an acidic catalyst, light unsaturated hydrocarbon molecules react and combine with each other to form larger hydrocarbon molecules. When considering the petroleum petroleum it is important to consider the fact that the overall classification will have an effect on the value, not just the physical properties.

For example, petroleum with a geographical classification from one region of the world may be expensive to transport to another region of the world regardless of the suitability of the raw petroleum as an overall substance.

In general, lighter crude commands a higher price because it contains more hydrocarbon chains that can be easily refined to make gasoline and diesel, which are in high demand. The lower the sulphur content, the higher the price as well because low-sufur, sweet crude requires less refining.

Classification of petroleum also indicates the best use for a particular field of petroleum.
