such towers are basically to separate the liquids having boiling points very closer (fractional distillation) so the length of the tower is useful for separation of condensing material and evaporating material, higher is the length of the tower more purity of a fraction we get.

Fractionating towers in refineries are tall to allow for better separation of components based on their boiling points. By having a tall tower, there is more space for the different fractions to separate vertically as they rise, resulting in better purity and efficiency of the refining process. The height of the tower allows for greater contact between the rising vapor and descending liquid, facilitating separation.
