Advantages and disadvantages of Freezing: Theoretically, freezing has some advantages over distillation. These advantages include a lower theoretical energy requirement, minimal potential for corrosion, and little scaling or precipitation. The disadvantage is that it ir.volves handling ice and water mixtures that are
Simple distillation condenses the liquid once, so the boiling points of the two liquids must be far apart to make it efficient. The number of simple distillations in a fractional distillation apparatus depend on the length and efficiency of the fractionating column. The process is the same; the difference is mainly one of iteration. Oct 21, 2020 · ADVANTAGES DISADVANTAGES.
