Petroleum refining or Oil refining is an industrial process in which crude oil is extracted from the ground and transformed and refined into useful products like Liquefied Petroleum Gas (LPG), kerosene, asphalt base, jet fuel, gasoline, heating oil, fuel oils etc. Crude Oil consists of hydrocarbon molecules.

♣There are three steps in the Petroleum refining process:

∆Separation,
∆Conversion,& ∆Treatment.

It would not be possible to travel by vehicle without petrol or diesel oil. Learn how do we obtain petrol and crude oil and also more about petroleum or oil refineries.

♣What is Petroleum?

Petroleum is a substance that occurs naturally. It is a dark liquid. It occurs beneath the earth’s surface. A large number of products like petrol, diesel, lubricating oil, etc derive from petroleum. Its compounds can be separated with the help of fractional distillation. In the year 2006, primary sources of energy consisted of petroleum 36.8%, natural gas 22.9%, and coal 26.6% share for fossil fuels in primary energy production in the world.

♣Formation of petroleum:

It takes around millions of years for petroleum to form. It is formed due to the presence of decomposed carcasses of dead animals beneath the surface of the earth. These carcasses of dead animals are subjected to extreme pressure and heat. Over centuries, millions of animals lived and died to become fossilized, just in case of plant-based matter. Similarly, in the ocean, oceanic creatures drowned to the bottom of the ocean and got buried under the sand and rocks.

Decayed due to the presence of bacteria, the decomposed organic matter got buried deeper and deeper over the years. Over millions of years, high temperature, high pressure, the absence of air converted the dead animals to petroleum and coal. This liquefied form of dead organic matter is petroleum or crude oil. Crude oil is extracted from oil wells, these wells can be very deep. The oil extracted is later refined to form petrol, diesel, aviation fuel, paraffin wax, lubrication oil, etc.

♣Petroleum Refining Process,
refining of petroleum:

Deposition of petroleum occurs with natural gas in the rocks called oil wells from where it is taken out by drilling. Refining is a process where the separation of various compounds of crude oil occurs. Fractional distillation is a process used to separate its compounds.

Crude Oil procured from an oil well is a mixture of many liquids. Different temperature evaporates a different liquid. This temperature is the boiling point of that liquid. The crude oil is heated to a temperature of 600-degree Celcius, is fed in at the bottom of the column and heated further. The liquid with the lowest boiling point changes into vapor first and condenses. At higher temperature, the next volatile liquid changes into a vapor state and rises.

Different vapors rise at different temperature and as they condense, they are collected in different trays. Different liquids are collected in different trays. A few gases reach the top of the column without condensing.

♣Products produced in Petroleum Refining Process:

: Generally, liquefied petroleum gas is useful for domestic fuel.

: Procuration of petrol occurs from this fraction.

: It is used as domestic fuel and also as fuel in jet engines.

: It is useful in the automobile industry.

: This type of oil is used in making lubricating oils.

: It is essential for ships, central heating, and factories.

: We can procure products like paraffin wax, bitumen from this residue. It is useful for making roads and roofing.

What Is Paraffin and What Are Its Uses?

Paraffin, also known as liquid paraffin, paraffin oil or kerosene, is a combustible hydrocarbon liquid that is burned as a fuel. It is a mixture of different types of simple hydrocarbons, it is less volatile than gasoline and it boils at 302-527 degrees Fahrenheit. Paraffin can be extracted from coal, wood and oil shale, but it is primarily obtained from the distillation of petroleum, which was first distilled in 1807 by geologist Abraham Gesner. The cost of producing paraffin was high, however, when new sources of paraffin and cheaper methods of refining were later discovered, it lead to lower prices of the fuel. Paraffin, when found in solid form, is called paraffin wax, while the liquid form is referred to as paraffin oil. Liquid paraffin oil is a mineral oil that comes in two forms, either heavy liquid paraffin oil or light liquid paraffin oil. Paraffin is clean burning and maintains a high heat output.

Paraffin Uses

Paraffin is a alkane hydrocarbon that has a variety of practical uses in industries such as medicine, agriculture and cosmetics. Paraffin is widely used as fuel for jet engines and rockets and as fuel or a fuel component for diesel and tractor engines. In centuries past, before electricity was invented, paraffin was used in lamps and lanterns as the main source of lighting. Today, paraffin is the most widely used heating oil in home central heating systems in the UK and it is still used in less developed countries as the main fuel for cooking. Paraffin is also used as a fuel in portable stoves during outdoor activities and mountaineering. Liquid paraffin can be used as a lubricant for machinery. Lubricants can help to extend the life of expensive machinery and equipment by reducing friction, binding and wear. Paraffin can also be used as a coolant for electrical systems, as hydraulic fluid and as a solvent for greases and insecticides. Liquid paraffin also has medicinal properties. It is commonly used to treat dry skin, constipation, and eczema. Paraffin wax is also used as a water-harvesting soil treatment to supply runoff water to dry areas, as an adhesive and as a water-proofing agent.
