∙ Crystallization is a separation process that makes use of differences in solubility of the components present in the melt or the solution ∙ Simple distillation is a procedure by which two liquids with different boiling points can be separated. ∙ A fractional distillation is used when separating mixtures of liquids whose boiling points are almost similar(difference is less than 25oC ) ∙ Steam distillation is a procedure by which steam volatile liquids can be separated.
