Crude Oil What Is It Used For

Crude Oil What Is It Used For – The fuel used in modern cars, be it gasoline, diesel or even LPG (Liquid Petroleum Gas), must have high purity standards for a successful car engine.

The crude oil is then broken down into its constituent hydrocarbons in a column of particles. Light fuels, including gasoline, are transferred from the top of this column, while heavier ones, such as diesel, are separated from the bottom.

Crude Oil What Is It Used For

Modern fuels must be able to ignite quickly even in adverse conditions, and must have the right mixture of hydrocarbons to burn properly to produce useful energy in an internal combustion engine. The fuel must have the correct octane rating to avoid knocking (rapid detonation) which can damage the engine.

Use Of Oil

The internal combustion engine is designed to run at a certain level of fuel and tuned to run efficiently at the maximum fuel it can handle, so consistent quality is important to the fuel.

Motor oil and diesel are obtained from crude oil, which is a complex mixture of hundreds of different hydrocarbons and other by-products that must be removed during processing. Crude oil varies from source to source; they generally contain volatile liquids, gasoline and others, as well as many heavier, almost solid substances, such as bitumen.

Separating and washing gasoline and diesel from crude oil requires a complex process, which is carried out in the oil industry.

The oil is distilled into its constituents through a process called fractional distillation. It separates the different types of crude oil using the fact that it boils and vaporizes at different temperatures.

Distillation Of Crude Oil & Oil Products

The first process is carried out in a fractionation column, a cylindrical tower up to 75 m high, in 30 and 40 trays called fractionation trays, which are mounted on top of each other. The bottom of the column is kept very hot but the temperature drops as it goes up the column, so each tray is slightly cooler than the one below.

The crude oil is heated between 315°C and 370°C so that all but the heaviest components. Then, it is introduced at the bottom of the fractionation column in the form of a mixture of gas and liquid. Oil vapor rises up the column through a device, such as a bubble plug, in a tray of particles that mixes with the liquid that is already there. The liquid remains, and the heavy oil settles at the bottom of the column.

As the steam rises, it cools according to the drop in temperature of the trays. Whenever steam rises from a tray containing a liquid whose temperature corresponds to the boiling point of one of the components of the steam, that fills the tray. Another high quality perfume that goes up in the column.

Therefore, each component of the steam reaches the plate on which it is pressed. The result is a series of different substances, called fractions, which can be drawn into the column through the pipe.

There are six main parts. The hot, still gas when it reaches the top of the column is called refinery gas and is used as a stand-alone fuel.

The rest is organized in another factory. The thermal properties of the resulting liquid droplets are highly variable when mixed with gasoline.

This is followed by naphtha (used for further processing into petrochemicals or alternatively for blending with gasoline), kerosene (which is paraffin), diesel and fuel oil and heavy fuel used for industrial oil, then the worst part , bitumen, the rest. as the rest.

Basic distillation processes separate crude oil into its chemically pure hydrocarbons. But some of these hydrocarbons are more valuable than others. In particular, the demand for gasoline is higher than that of bitumen, or even diesel. Therefore, some of the heavy particles are converted into gasoline in the refinery. This is done through a process called splitting.

In a flare, hydrocarbons are heated between 450°C and 540°C at high pressure. The result is low-grade petroleum that is refined at high temperatures and pressures to produce gasoline perfect for use in automobile engines.

Catalytic cracking is more beneficial than thermal cracking because it provides a higher yield of valuable products. By adding a catalyst (usually aluminum silica powder) to the oil during heating, the heavy particles are dispersed into a mixture of simple particles, which are fed into a small column to be separated.

These movements follow a process where the appropriate additives are introduced to make the mixed fuel suitable for winter or summer.

To be useful for running internal combustion engines, fuel must have certain properties. It should flow smoothly into the engine at high speed and power without detonation. This manifests as a “knock” and, if allowed to continue, can cause serious engine damage.

The gasoline must have volatile compounds that make the engine start quickly in winter. But the fuel should not be so volatile that it runs too fast and causes fuel system stalling or even carburetor icing (see limit, right).

The performance of a fuel is primarily measured by its octane rating. For this, gasoline is compared to two efficient fuels called n-heptane and iso-octane, both of which are hydrocarbons. N-heptane is a bad fuel for internal combustion engines and causes knocking; it has an octane rating of 0. Isooctane is a different, higher quality oil, and it has an octane rating of 100.

If the fuel has an octane rating of 90 this means that it gives its performance with a mixture of 90 parts iso-octane and 10 parts heptane. Most car engines require gasoline with an octane rating between 90 and 100.

As another thing to prevent knocking, it is still customary to add a little tetraethyl or tetramethyl lead to gasoline. However, this is always reduced due to the toxic nature of lead.

Where Does Gasoline Come From

The top rate of gasoline was lowered from 0.4 to 0.15 grams per liter in 1986, and unleaded gasoline began to appear on the European market. This is unleaded fuel.

Of the fuel – its mass that evaporates at a given temperature – will respect certain limits. If the shift is too low, the car engine is difficult to start and takes a long time to warm up. If it is high, the motor may

. In extreme cases, volatile fuel can cause carburetor icing because, as the fuel evaporates, it absorbs heat from its surroundings, causing the carburetor body to freeze cold enough that the water in -air heats up and blocks the nozzles.

Diesel fuel is more viscous and heavier than gasoline, does not move and exits the fractionator at a lower rate.

What Is The Process Of Crude Oil Refining

Diesel is not measured by octane like gasoline; instead, it is assigned a cetane number. This is achieved by comparing diesel fuel with two other hydrocarbons, cetane and alpha-methylnaphthalene.

High quality diesel fuel used in road vehicles has a cetane number of around 50, while low speed engines such as those used in large boats can run on petrol and low cetane. The higher the cetane number, the easier it is to start, making the fire brighter and reducing the level of “diesel burning”.

Some low-grade diesel fuel (called gasoline) used in station or highway operations is dyed for identification purposes and is therefore known as red diesel fuel. Only clean diesel fuel, subject to road tax, can be legally used on the road.

Diesel fuel, like gasoline, often contains dangerous additives. Anti-wax should be added to the diesel fuel used in the winter to prevent it from blocking the fuel lines and injectors.

From the refinery, gasoline and diesel are transported to depots and filling stations by road or by rail and organized trucks. .

The fuel is stored in an underground tank below the point of sale – service station. Gasoline and diesel are stored in separate tanks, as are the different grades of gasoline, until they are brought to the surface and measured for sale at the pumps.

The underground storage tanks are filled by boats with ropes that the boats attach each time they are full. Due to the risk of fuel vapor explosion, the risk of fire is reduced by using materials such as copper for the installation of cables and tools used to connect them.

Gasoline is stored underground in a filling station until it is sold, when pumps lift the gas from tanks above ground, and measure the amount of gas sold. Petrol and diesel are kept separate, as usual
