Franctional Distillation Of Crude Oil Flashcards
0
Q
What is crude oil made of?
A
Mixtures of lots of different hydrocarbons (alkanes and alkenes)
1
Q
How is crude oil formed?
A
From buried remains of plants and animals
2
Q
Describe process of fractional distillation
A
Oil heated until most turns into gas
Gases enter fractionating column, liquid (bitumen)
drained off at bottom.
Fractional column hotter at bottom, cooler at top.
Longer hydrocarbons with high boiling points turn into liquids and drain out nearer the bottom. Shorter hydrocarbons with lower boiling points drain off nearer the top.
3
Q
Name the order of hydrocarbons draining from fractional distillation column, bottom to top - 7
A
Bitumen Oil Diesel Kerosene (paraffin) Naphtha Petrol Liquid petroleum gas - LPG
