Chromatography is a technique for separating coloured chemicals such as ink. Chromatography is also to separate the components of a mixture for further use (and is thus a form of purification).
filtration aims to attain the separation of substances.The substance that is to pass through the filter must be a fluid, i.e. a liquid or gas.

If hot solution is allowed to cool, the solute forms crystals of pure compound.

About Fractional Distillation...
The various components of crude oil have different sizes, weights and boiling points.
The process call Fractional Distillation is used to separate crude oil into useful substances or fractions as they have different hydrocarbons of different boiling points.
The meaning of Fractional Distillation is separating chemical compounds by their boiling point by heating them to a temperature when several fractions of the compound will evaporate.
Distillation is a method of separating mixtures based on differences in their volatilities in a boiling liquid mixture. Distillation is a unit operation, or a physical separation process, and not a chemical reaction. Commercially, distillation has a number of applications. It is used to separate crude oil into more fractions for specific uses such as transport, power generation and heating. Water is distilled to remove impurities, such as salt from seawater. Air is distilled to separate its components—notably oxygen, nitrogen, and argon—for industrial use. Distillation of fermented solutions has been used since ancient times to produce distilled beverages with a higher alcohol content. The premises where distillation is carried out, especially distillation of alcohol, are known as a distillery.
Water can be purified by a process called distillation. Distillation can be separated into two. Simple distillation and Fractional distillation.Simple distillation is used to obtain the solvent from a solution. Fractional distillation is used to separate one liquid from a mixture of different liquids that have different boiling points. e.g.: If we wanted to make some PURE WATER from SEA WATER we would distill the sea water.

Some solids dissolve in water to make a solution. These solids are soluble. A solution is made from a solute and a solvent. When a solution is formed, the liquidis always clear. Solids that do not disolve are insoluble. When an insoluble solid is mixed with a solvent it will go cloudy. Sometimes the solid will sink to the bottom of the container containing the solvent. Milk contains insoluble particles.You cannot see through milk so it is not a solution. A solution is a mixture and it is possible to seperate the solute from the solvent by evaporation.
