Crude oil is separated by fractional distillation in an oil refinery.
Because different fractions separate at different temperatures.
No, it is a physical process.
Oil refining is the process of distilling oil and then further reforming, catalytic cracking, hydrofining, blending, and sometimes coking, hydrocracking, alkylating various fractions of the distilled oil.
Oil and water naturally do not mix, so separating them is not too difficult.You have to just pour the upper part of the solution (the oil) into other container. This process is also known as decantation.
Gasoline is a hydrocarbon obtained by separating crude oil into component fractions in a fractionating column; so yes a hydrocarbon can power an internal combustion engine.
there is only one process. that is fractionation. it can also be said fractional distillation.
Distillation

Dude you in mrs forewards class in bish? If you are then....your screwed, and were both failing :D
Refinery
A simple method is decantation.
Petrol, fuel oil , disel oil
