It's called Distiling...
Crude oil is a micture of diffrent lengths of Hydrocarbons and they each boil at diffrent tempretures so the Crude Oil is put into a big tube (sort of) and then heated up and each set of hydrocarbons will boil at a different tempreture and will reach the top of the tub were it is then collected...
Very basic answer...

What is the meaning of Brent oil?
Brent crude oil is a "benchmark crude" oil agreed upon by various suppliers and traders of crude oil. Other crude oils are often priced based on the agreed upon benchmark crude which has a particular set of properties.

What is the meaning of refinery of crude oil?
A crude oil refinery is a factory. The factory takes the crude oil, and turns it into useful products, like gasoline.
What is the name of a factory where crude oil is made?
Crude oil is not "made". "Crude oil" is the name giving to the raw form of oil that is pumped from the ground.
What is done to the crude oil before it enters the column?
Crude oil is heated at about 350 degrees
Is crude oil a chemical?
Crude oil is a complex mixture of a great many different chemicals.
Are clothes made from crude oil?
Yes, some synthetic fabrics like polyester and nylon are derived from crude oil. The oil is broken down into its chemical components to create fibers that are then used to make clothing.
Why does crude Oil not dissolve in water?
Crude oil is hydrophobic, which means it repels water and is not soluble in it. This is due to the nonpolar nature of the hydrocarbon molecules in crude oil, which do not interact well with the polar molecules in water. As a result, crude oil will not dissolve in water but will float on its surface.
what chemical in crude oil is more volatile oxygen carbon hydrogen or nitrogen?
Crude oil contain compounds of O, C, H, N and not chemical elements.
What is the role of chemistry in purifying crude oil in an oil refinery?
All the processes involved in the refining of crude oil are chemical processes; this is the field of petrochemistry.
What is an example of catalytic cracking?
"Cat cracking" is the process used to break crude oil down into gasoline, kerosene, adn fuel oils.
Explain how the different chemical compounds in crude oil are separated?
Crude oil is separated into different chemical compounds through a process called fractional distillation. This process involves heating the crude oil to high temperatures, then cooling it in a fractionating column. The different compounds in crude oil have different boiling points, allowing them to be separated based on their molecular size and weight.
What are the reasons NYMEX crude oil goes up and down in price?
There are many reasons why NYMEX crude oil goes up and down in prices. This includes the level of production from crude oil suppliers as well as world events and government policy.
Boiling point of crude oil?
There is not a "cut and dry" answer to this as the boiling of crude oil is a process. Heated to about 500 C the covalent carbon-carbon bonds begin to break during the "cracking process" - or breaking down of large molecules of heavy heating oil. computer says 500 oC
What is demulsifier?
Demulsifier is type of chemical mostly used with or injected on wet crude oil,
What chemical element is bonded to hydrogen to make up crude oil?
fuel pump
Is crude oil used to make fibers?
No, crude oil is not directly used to make fibers. Synthetic fibers like polyester and nylon are made from petrochemicals derived from crude oil through a series of chemical processes. The crude oil serves as a source of the raw materials needed to produce synthetic fibers.
