Petroleum is a naturally occurring, yellowish-black liquid found in geological formations beneath the Earth’s surface. It is commonly refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation, i.e. separation of a liquid mixture into fractions differing in boiling point by means of distillation, typically using a fractionating column.It consists of naturally occurring hydrocarbons of various molecular weights and may contain miscellaneous organic compounds.
