Types of Separation
Chromatography is a separation technique that every organic chemist and biochemist is familiar with. I, myself, being an organic chemist, have routinely carried out chromatographic separations of a variety of mixture of compounds in the lab.
Crystallization is a commonly used technique for the purification of substances. It is a separation technique in which solids are separated from a solution. It is a separation technique in which solids are separated from a solution.
Decantation is a process used to separate mixtures of liquids and solids or two immiscible liquids. What is meant by decanting in chemistry? Decantation is a process used to separate mixtures of liquids and solids or two immiscible liquids.
Evaporation is the process by which water (and other liquids) changes from a liquid state to a vapor or gas state. Evaporation is great for separating a mixture (solution) of a soluble solid and a solvent.

Fractional distillation of crude oil Because they have different boiling points, the substances in crude oil can be separated using fractional distillation. The crude oil is evaporated and its vapours allowed to condense at different temperatures in the fractionating column. Each fraction contains hydrocarbon molecules with a similar number of ...
Simple distillation may be used when the boiling points of two liquids are significantly different from each other or to separate liquids from solids or nonvolatile components. In simple distillation, a mixture is heated to change the most volatile component from a liquid into vapor.
Sublimation separates a mixture of solids, one of which sublimes. A few substances change directly, from a solid to vapour on heating without going through the liquid state. This change is called sublimation. On cooling, water vapour changes back to solid directly.
