Definition Of Oil
Oil is the world’s most important fuel and underpins our high standard of living. It provides modern convenience and freedom of movement and is crucial to transport systems. Oil refining produces transport fuels, such as petrol (gasoline), diesel and jet fuel, as well as heating oils such as kerosene. By-products from oil refining are also valuable.
They are used in the production of plastics and chemicals, as well as many lubricants, waxes, tars and asphalts. Nearly all pesticides and many fertilisers are made from oil or oil byproducts. Oil has been produced commercially and refined since the 1850s.
Oil is formed deep underground from the decomposition of organisms such as plankton and algae. Over millions of years, heat and geological pressure transform this organic matter into oil and gas.
What Is Crude Oil?
Crude oil is a naturally occurring, unrefined petroleum product composed of hydrocarbon deposits and other organic materials. A type of fossil fuel, crude oil can be refined to produce usable products such as gasoline, diesel and various forms of petrochemicals. It is a nonrenewable resource, which means that it can’t be replaced naturally at the rate we consume it and is, therefore, a limited resource.
Crude oil is typically obtained through drilling, where it is usually found alongside other resources, such as natural gas (which is lighter and therefore sits above the crude oil) and saline water (which is denser and sinks below). It is then refined and processed into a variety of forms, such as gasoline, kerosene, and asphalt, and sold to consumers.Although it is often called "black gold," crude oil has ranging viscosity and can vary in color from black to yellow depending on its hydrocarbon composition. Distillation, the process by which oil is heated and separated in different components, is the first stage in refining.
History of Crude Oil
Although fossil fuels like coal have been harvested in one way or another for centuries, crude oil was first discovered and developed during the Industrial Revolution, and its industrial uses were first developed in the 19th century. Newly invented machines revolutionized the way we do work, and they depended on these resources to run. Today, the world’s economy is largely dependent on fossil fuels such as crude oil, and the demand for these resources often spark political unrest, as a small number of countries control the largest reservoirs. Like any industry, supply and demand heavily affect the prices and profitability of crude oil. The United States, Saudi Arabia, and Russia are the leading producers of oil in the world.
Petroleum Derivatives: Synthesis and Application
Petroleum products are materials derived from crude oil (petroleum) as it is processed in oil refineries. Unlike petrochemicals, which are a collection of well-defined usually pure chemical compounds, petroleum products are complex mixtures. The majority of petroleum is converted to petroleum products, which includes several classes of fuels.
According to the composition of the crude oil and depending on the demands of the market, refineries can produce different shares of petroleum products. The largest share of oil products is used as “energy carriers”, i.e. various grades of fuel oil and gasoline. These fuels include or can be blended to give gasoline, jet fuel, diesel fuel, heating oil, and heavier fuel oils. Heavier (less volatile) fractions can also be used to produce asphalt, tar, paraffin wax, lubricating and other heavy oils. Refineries also produce other chemicals, some of which are used in chemical processes to produce plastics and other useful materials. Since petroleum often contains a few percent sulphur-containing molecules, elemental sulphur is also often produced as a petroleum product. Carbon, in the form of petroleum coke, and hydrogen may also be produced as petroleum products. The hydrogen produced is often used as an intermediate product for other oil refinery processes such as hydrocracking and hydrodesulphurization.
