How are the hydrocarbons in crude oil separated?
How are the hydrocarbons in crude oil separated?
This then will be a relatively simplistic look at the different potential hydrocarbons that might make up a crude oil, and how we can get them apart.
What kind of compounds are found in crude oil?
Compounds that contain only elements of carbon and hydrogen are called hydrocarbons and constitute the largest group of organic compounds found in petroleum. There might be as many as several thousand different hydrocarbon compounds in crude oil. Hydrocarbon compounds have a general formula of C x H y, where x and y are integer numbers. Figure 1.7.
What is the chemical constitution of crude oil?
Chemical Constitution of Crude Oil. Crude oil contains organic compounds, heteroatom compounds (S,N,O), hydrocarbons (C, H), metals and organic (Ni, V, Fe) and inorganic (Na +, Ca ++, Cl -) compounds as listed in Figure 1.7.
What makes up a fraction of crude oil?
Crude oil is a mixture of hydrocarbons. The crude oil is evaporated and its vapours condense at different temperatures in the fractionating column. Each fraction contains hydrocarbon molecules with a similar number of carbon atoms and a similar range of boiling points.
How is crude oil separated into hydrocarbons and crude oil?
Separating crude oil. Fran Scott explains fractional distillation – the separation of crude oil into fractions. Fractional distillation is used to separate crude oil into simpler, more useful mixtures. This method can be used because different hydrocarbons have different boiling points.

Why is distillation used to separate crude oil?
Some fractions undergo cracking to help meet demand for the smaller molecules. Fractional distillation is used to separate crude oil into simpler, more useful fractions. A fraction of crude oil is a group of hydrocarbon molecules of similar size with similar boiling points.
How is crude oil different from other liquids?
These liquids are used to make petrol, paraffin, diesel fuel etc. Crude oil is a mixture of different chemical called hydrocarbons. The boiling oil turns into a mixture of gases in the column. The gases flow up the column which is hottest at the bottom and cooler at the top.
