The process of centrifugation is used in Diaries to separate cream from milk .centrifugation is the method of separating the suspended particles of a substance from a liquid in which mixture is rotated .

2.Fractional distillation is amplifier separate mixer of two or more volatile liquids having boiling points close to each other .

3.An air separation plant separates atmospheric air into its primary components,typically nitrogen and oxygen .
