Samuel M. Kier, a native of southwestern Pennsylvania, was the first person to refine crude oil. In the mid-1840s, he became aware of crude oil through his salt business. Occasionally, wells drilled for salt water would produce foul-smelling petroleum alongside the brine. For many in the salt business, the oil was a nuisance, and they were content to burn it or allow it to run off into nearby waterways. However, Kier was an entrepreneur, and he believed that he could turn the oily by-product of his salt wells into something of value.

Kier first used the flammable oil produced by his salt wells to light his salt works at night. The burning crude produced an awful smell and a great deal of smoke. Nevertheless, Kier was able to light his business without paying for an expensive illuminant like whale oil. Next, Kier packaged pure crude oil in half-pint bottles for sale as a medicine. A bottle of Kier’s Petroleum sold for 50 cents.

 

First Attempts Attempts at commercializing Oil

Kier knew crude oil would burn and thought that it could make a good and inexpensive lamp oil. However, the smell and smoke that burning oil produced made it hard to sell as an illuminant. In 1849, Kier took samples of his crude oil to Philadelphia where they were analyzed by Professor James C. Booth, a chemist. Booth agreed that crude oil could be used for illumination, but that it needed to be distilled or refined to get the best burning fluid. Thus, in 1850, Kier started experimenting with distillation and became the first person in the U.S. to attempt to use liquid petroleum as a starting material to produce lamp oil. His refining experiments were successful and by 1851, Kier produced a product called Carbon Oil, a fuel oil which burned with little smoke and odor. He sold his Carbon Oil for $1.50 a gallon.

In partnership with John T. Kirkpatrick, Kier created the first U.S. petroleum refinery in Pittsburgh, Pennsylvania

EARLY REFINERIES

In the early days of the oil industry, the methods for refining oil were very different than the methods we use today. People like Samuel M. Kier used horizontal cylindrical stills that only held 5 to 6 barrels of oil at a time. Using the stills, refiners were able to raise the temperature of the oil very slowly. As the temperature rose, they removed the distillates like gasoline for which they had no use, procuring only the lamp oil or kerosene

 

 

MODERN REFINING(fractional distillation).

This process separates the different components of crude oil so that they can be further refined.

Just as water goes from liquid to vapour at approximately 100°C, each type of hydrocarbon changes from liquid to vapor within a specific temperature range. In general, the more carbons in a molecule, the higher its boiling point. This allows for separation within the distilling process.

Fractional distillation begins when the crude oil, which is a mixture of different hydrocarbons, is put into a high-pressure steam boiler. This is a tank that makes the oil boil and turn to vapor, much like boiling water turns into water vapor. The crude oil is heated to temperatures up to 600° Celsius.

After the oil becomes vapor, it enters the bottom of the distillation column through a pipe. The distillation column is a tall tank that contains many plates or trays. The vapor rises in the column, cooling as it rises. The specific vapors cool at their boiling points and condense on the plates or trays in the column. Much like water condensation on the outside of a cold glass, the vapors turn into liquid fractions as they condense. The liquid fractions flow through pipes and are collected in separate tanks. The fractions include gases, naphtha, gasoline, kerosene, diesel fuel, lubricating oils, heavy oils, and other materials.

CRUDE OIL

There are different grades of crude oil, each with a specific composition determined by the original decomposed source materials as well as the properties of  the surrounding soil or rock formations. It can be light or heavy (referring to density) and sweet or sour (referring to its sulfur content).

 

OIL PRODUCTS

Asphalt

Asphalt is commonly used to make roads. It is a colloid of asphaltenes and maltenes that is separated from the other components of crude oil by fractional distillation. Once sphalt is collected, it is processed in a de-asphalting unit, and then goes through a process called “blowing” where it is reacted with oxygen to make it harden. Asphalt is usually stored and transported at around 148.9° Celsius.

Diesel

Diesel is any fuel that can be used in a diesel engine. Diesel is produced by fractional distillation between 200° Celsius and 350° Celsius. Diesel has a higher density than gasoline and is simpler to refine from crude oil. It is most commonly used in transportation.

Fuel Oil

Fuel oil is any liquid petroleum product that is burned in a furnace to generate heat. Fuel oil is also the heaviest commercial fuel that is produced from crude oil. The six classes of fuel oil are: distillate fuel oil, diesel fuel oil, light fuel oil, gasoil, residual fuel oil, and heavy fuel oil. Residual fuel oil and heavy fuel oil are known commonly as navy special fuel oil and bunker fuel; both of these are often called furnace fuel oil.

Gasoline

Almost half of all crude oil refined in the United States is made into gasoline. It is mainly used as fuel in internal combustion engines, like the engines in cars. Gasoline is a mixture of paraffins, naphthenes, and olefins, although the specific ratios of these parts depends on the refinery where the crude oil is processed. Gasoline refined beyond fractional distillation is often enhanced with iso-octane and ethanol so that it is usable in cars.

Gasoline is called different things in different parts of the world. Some of these names are: petrol, petroleum spirit, gas, petrogasoline, and mogas.

Kerosene

Kerosene is collected through fractional distillation at temperatures between 150° Celsius and 275° Celsius. It is a combustible liquid that is thin and clear. Kerosene is most commonly used as jet fuel and as heating fuel. In the early days of oil, kerosene replaced whale oil in lanterns. In the early 21st century, kerosene was used to power New York City Transit buses. Now, kerosene is used as fuel in portable stoves, kerosene space heaters, and in liquid pesticides.

Liquefied Petroleum Gas

Liquefied petroleum gas is a mixture of gases that are most often used in heating appliances, aerosol propellants, and refrigerants. Different kinds of liquefied petroleum gas, or LPG, are propane and butane. At normal atmospheric pressure, liquefied petroleum gas will evaporate, so it needs to be contained in pressurized steel bottles.

Lubricating Oil

Lubricating oils consist of base oils and additives. Mineral oils are manufactured by special processes called: solvent extraction, catalytic dewaxing, hydrocracking, and isohydromerization. Different lubricating oils are classified as paraffinic, naphthenic, or aromatic. Lubricating oils are used between two surfaces to reduce friction and wear.

Paraffin Wax

Paraffin wax is a white, odorless, tasteless, waxy solid at room temperature. The melting point of paraffin wax is between 42.2° C and 63.9° C, depending on other factors. It is an excellent electrical insulator, second only to Teflon®, a specialized product of petroleum. Paraffin wax is used in drywall to insulate buildings. It is also an acceptable wax used to make candles for the Jewish Menorah.

Bitumen

Bitumen, commonly known as tar, is a thick, black, sticky material. Refined bitumen is the bottom fraction obtained by the fractional distillation of crude oil. This means that the boiling point of bitumen is very high, so it does not rise in the distillation chamber. The boiling point of bitumen is 525° C. Bitumen is used in paving roads and waterproofing roofs and boats. Bitumen is also made into thin plates and used to soundproof dishwashers and hard drives in computers.

Petrochemicals

Petrochemicals are the chemical products made from the raw materials of petroleum. These chemicals include: ethylene, used to make anesthetics, antifreeze, and detergents; propylene, used to produce acetone and phenol; benzene, used to make other chemicals and explosives; toluene, used as a solvent and in refined gasoline; and xylene is used as a solvent and cleaning agent.

NB:

crude oil is the starting point for many diverse products such

–       clothes, threads, straps, shoe laces, plastic shoes, sandles, soles
