Mass Transfer
Steam distillation is not recommended to be used, if the

Material can not be distilled by indirect heating even under low pressure, because of the high boiling temperature

Liquids decompose, if distilled directly at atmospheric pressure

Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature

Azeotropic mixture is to be separated and the final product is miscible with water
