Fractional distillation
Method of separating hydrocarbons to get crude oil. produces different fractions which have different purposes shorter chains can be used for petrol and small gases like Bunsen burners and longer chains are used for diesel.
Crude oil cycle: Fossil fuel formed from the remains of dead animal and plant matter that has been buried under mud and compressed due to high temps and pressures where it turns to crude oil.
Method: 1) The oil is heated till it evaporates (turns to a gas) The gas enters the functioning column. 2) At the bottom of the collum the temp is really high however at the top the temps ar cooler 3) The longer hydrocarbons have higher boiling points (equal to the temp they will condense at) So they condense near to the bottom of the column. But ones with lower boiling points will rise higher and condense at cooler temps. Some hydrocarbons have much high boiling points that they are drained out as a liquid as waste product.
