Crude oil Flashcards
What mixture does Crude Oil contain?
Hyrdocarbons
What are Hydrocarbons?
Compounds that only contain Carbon and hydrogen elements
Since, Crude oil have diffrent boiling points what method is used to sepreate Crude oil?
Fractional Distillation
Talking about the diffrent fractions
What does Pa Pa Never Kick Dear Lily’s Back mean?
(P.P.N.K.D.L.B)
Liquefied Peetroleum Gas (LPG), Petrol (Gasoline), Naphtha (Na/ph/tha), Kerosene, Diesel, Lubricating oils, Bitumen
What is the function of LPG?
Fuel used for cooking
What is the function of Petrol (gasoline)
Fuel used in cars
What is the function for Naphtha?
Feedstock for the petrochemical industry
Naphtha is used as feedstock for pyrolysis (NCC) to produce ethylene, propylene, butadiene, benzene, toluene and xylene that are basic feedstock for petrochemistry
What is the function of kerosene?
used as fuel for Aircraft engines
What is the function of Diesel?
Used to fuel Diesel engines
What is the function of Lubricating oils?
A source of Polishes and Waxes
What is the function of Bitumen?
Used to make road surfaces
How is crude oil sepreated via. Fractional distillation?
- Crude oil is heated in a furnace and turns into vapour which enters the fractionating column.
- The hot vapour rises up the column and cools down and each fraction condenses at a different temperatures.
- The fraction with the lowest boiling point is at the top and the fraction with the highest boiling point is at the bottom.
What are the changes that occur among the diffrent fractions of crude oil from top to the bottom? (Physical properties)
Boiling point increases and Thickness increases
What are the changes that occur among the diffrent fractions of crude oil from top to the bottom? (Chemical property)
Flammability decreases
Why does the boiling point increase?
- The size of the molecules increase.
- Which causes the IMFA (intermolecular forces of attraction) to increase.
- Hence, more energy is needed to overcome the IMFA.
